Cultivation before the Iron Age (500
BC)?

We review the evidence for the earliest agriculture in Finland. The claims are all based on pollen
analysis. Some claims go back to the Neolithic period. We contest these claims critically and argue that
the ‘early cereal-type’ pollen grains may in fact come from large-grained wild grasses, and cannot be
taken as clear evidence for cultivation in the absence of other lines of evidence. Cultivation of cereals in
Finland may have started as late as the start of the Iron Age in c. 500 BC.

INTRODUCTION
In this contribution, we consider the start
of agriculture in Finland. Finland would
have presented a major challenge to early
farmers. It lies north of 60°N (Figure 1),
and close to the northern limit for deciduous forest. However, it is still possible to
practise cultivation, although modern
farming is concentrated in the southwestern
corner and coastal areas. In most of
Europe, the agricultural transition is
equated with the start of the Neolithic.
This is not, however, the case in Finland,
where the start of the Neolithic is defined
by the appearance of pottery (see Figure 2).
The question ‘when did cultivation start?’ is
under discussion in various parts of
Europe, but while the question elsewhere is
‘was there pre-Neolithic cultivation?’ (e.g.
Rowley-Conwy, 2004; Behre, 2007), in
Finland it is ‘was there pre-Iron Age cultivation?’ In Finland, the Iron Age started c.
500 cal BC, and continued until AD 1200.

There is still no consensus as to when
cereal cultivation started in Finland. Some
have suggested that cultivation started as
early as 3200–2300 cal BC, in the Neolithic Corded Ware (CW) culture
(Vuorela & Hicks, 1996; Alenius et al.,
2009; Mökkönen, 2010). Mökkönen
(2010) suggests that the first cultivation
might have begun even earlier. More
recently, Alenius et al. (2013) and Nordqvist and Herva (2013) have argued that it
could have been as early as the appearance
of the first ceramics in 5000–4000 BC.
These claims of early cultivation have
sometimes been used uncritically (e.g.
Costopoulos et al., 2012; Nordqvist &
Herva, 2013). Finland, like other northern
areas, generally has very poor organic preservation on archaeological sites, so finds of
animal bones and macrobotanical plant
remains are very rare. Many of the claims
for early agriculture are therefore based on
palynological records (Huurre, 2003),
often single grains of cereal-type pollen.

We will argue that cultivation may have
begun much later, as late as the start of
the Iron Age (c. 500 cal BC). Finland is
not alone in claiming early agriculture on
the basis of pollen evidence (see the
important paper by Behre, 2007). In
Britain, Edwards (1989) identified numerous traces of ‘cereal-type’ pollen of
Mesolithic age, but in a recent major
study, Whittle et al. (2011: 808, 849)
reject these claims and date the start of
farming to the Neolithic. Claims for
Mesolithic ‘cereal-type’ pollen have also
recently been advanced in central and
southern Europe (e.g. Tinner et al., 2007;
Jeunesse, 2008). Other areas of northern
Europe have seen a similar debate. In
northern Norway, Johansen and Vorren
(1986) argued that ‘cereal-type’ pollen
indicates that agriculture started in the
mid-third millennium cal BC, although
other lines of evidence suggest a date not
much before 1000 cal BC (Valen, 2007).
The Finnish debate should thus be seen as
part of a wider European discussion.
EARLY AGRICULTURE IN FINLAND: THE
DEBATE
The Late Neolithic Corded Ware and
Kiukainen cultures
The traditional view has been that farming
was introduced into southern Finland by
people of the CW archaeological culture

(see Figure 1 for the CW distribution).
This typologically Late Neolithic culture is
associated with agriculture across a wide
area of Europe. Various arguments have
been advanced to support the claim for
cultivation in Finland. Most of these
involve pollen, and will be considered in
detail below. The most recent claim that
the Finnish CW was agricultural has been
put forward by Mökkönen (2010).
Mökkönen used new data concerning
changes in settlement pattern, and a correlation between spruce and the CW
culture, to claim that the CW people were
cultivators. The change in settlement
pattern was from more sheltered inland
areas towards more coastal and open sites.
This change could, however, be interpreted in the opposite way: there is no
clear reason why such a settlement shift
Lahtinen and Rowley-Conwy — Early farming in Finland
should be connected to cultivation, and it
is questionable whether cultivation has
anything to do with it. It might equally
indicate more intensive fishing as part of
an adaptation to the climate change.
Previous discussions have alluded to
CW cultivation. Nuñez (2004) stresses the
weaknesses in the evidence, but argues
that the CW was indeed likely to have
been partially agricultural, mainly based on
the fact that CW people were agriculturalists elsewhere. He believes that farming
was environmentally vulnerable this far
north, and may have suffered a setback
and disappeared almost totally soon after
the CW period. Edgren (1999) argues
that positive indicators of cultivation by
the CW culture are lacking, and that the
argument is based purely on the situation
at CW sites in Sweden and the Baltic
countries. Edgren believes that it is unlikely that cultivation occurred during the
Late Neolithic period, although he does
not say when it did start. He points out
that the Pre-Roman Iron Age was the
period of intensification of cultivation in
southern Finland.
There have been various critiques of
these early farming claims. Zvelebil and
Rowley-Conwy (1984) wrote that ‘the
palynological evidence for CW farming in
Finland rests on a few uncertain identifications of cereal pollen—evidence which
in view of the great similarities in size and
shape of other Gramineae pollen…, could
hardly justify the belief that CW economy
was based on farming’ (Zvelebil &
Rowley-Conwy, 1984: 115). Finds of
single pollen grains have subsequently
increased, but the same problems with
reliability have remained (see Discussion
below).
Direct evidence for CW agriculture
continues to elude archaeologists. A recent
major radiocarbon programme using accelerator mass spectrometry was directed
towards potential early domestic animal
663
bones. None of the bones dated were of
CW age; most were recent or modern in
origin (Bläuer & Kantanen, 2013).
Although the evidence from the subsequent Kiukainen period is broadly
similar, one domestic animal bone, a
sheep/goat carpal, has been directly dated
to this period. The bone is from Pedersöre
Kvarnabba, remarkably far north on Finland’s west coast (see Figure 1), and is
dated to 3679 ± 33 BP (Ua-43043)
(Bläuer & Kantanen, 2013: Table 1), or
2192–1960 cal BC1. It is also possible that
animal herding and cereal cultivation were
adopted at different times.
THE BRONZE AGE
There is some published evidence that
could support Bronze Age cultivation.
Zvelebil (1981) used productivity modelling to compare site locations and
connections to land which is suitable for
cultivation in south-western Finland.
He showed that CW sites were not situated in close proximity to potential arable
land. However, during the Bronze Age,
the proximity of the archaeological sites to
land suitable for cultivation increased.
Thus, Zvelebil (1981) concluded that the
Bronze Age economy was a combination
of farming and hunting. However, since
direct evidence is missing, this alone need
not prove anything about cultivation. Such
potentially cultivable areas can also be rich
in natural flora, and might be optimal for
wild animals such as elk (Alces alces).
Another possibility is that these results
simply reflect land uplift that made former
sea floor sediments, like arable clays and
silts, more available in the Bronze Age, as
hunters also benefit from close proximity
to watercourses. As Zvelebil and Rowley1

Conwy (1984: 117) note, there is an ‘autocorrelation
between
watercourses,
sedimentary basins and soil fertility.’
According to Zvelebil (1981), arable land
does not become a major focus of the
settlement pattern in south-western
Finland during the mid-first millennium
AD.
Sarmaja-Korjonen (1992: 146) argues
that ‘there is no detailed Finnish pollen
record that indicates continuous farming
from the Bronze Age onward’. She points
out that biostratigraphical correlation with
the archaeological record might be poor
because of wide error ranges in the radiocarbon dates, and also believes that cereal
pollen might have been transported over
long distances; thus, a decline in Picea
(spruce) pollen together with single
Cerealia-type pollen grains should be
treated very cautiously as evidence of local
cultivation. However, other palaeobotanists have suggested that cultivation began
in the Bronze Age. Tolonen (1984) argues
that the results from three pollen analyses
in southern Finland are reliable. Two of
those studies, from lakes Kantala and Kissalammi, suggest that cultivation started in
the Late Bronze Age (Tolonen, 1978a,
1981). One of these is from Lake Ahvenainen, and has one pollen grain of
Triticum-type and one of Hordeum-type in
a level dated by varves to 1200–1300 BC
(Tolonen, 1978b). Simola (1999) discusses
cultivation in the Bronze Age as if it was
an established fact, but does not give any
references to support this idea. Having
said this, he does admit that signs of early
cultivation are scarce, and can only be seen
in a small area of south-western Finland
before the Iron Age (Simola, 1999).
Macrofossil evidence for agriculture
remains very scarce. One directly dated
domestic animal bone, a cow maxillary
molar from Nakkila Viikkala, is dated to
3086 ± 30 BP (Hela-1271) (Bläuer &
Kantanen, 2013: Table 1), or 1427–1271
cal BC. This is further south-west than
the Kuikainen example mentioned above
(Figure 1). These two bones remain the
only directly dated evidence of domestic
animals in Finland that necessarily predate
the Iron Age.
Charred cereal grains are also very
scarce. One directly dated grain of barley
has been recovered from a multiperiod site
from Kotirinne in Niuskala in the city of
Turku (Figure 1). 30 years after its discovery, it remains ‘the oldest cereal grain find
in Finland’, with a radiocarbon date of
3200 ± 170 BP (Ua-338), or 1891–1018
cal BC (Vuorela & Lampiäinen, 1988:
33). It is derived from a ‘grain from the
lower part of the undisturbed layer’
(Vuorela & Lempiäinen, 1988: 36). This
has been used as clear evidence of
Lahtinen and Rowley-Conwy — Early farming in Finland
cultivation (Vuorela & Hicks, 1996; Lempiäinen, 1999; Huurre, 2003; Mökkönen,
2010). This date is one of five from Niuskala, and when calibrated (Figure 3), they
show a remarkably wide degree of spread.
The date on the cereal grain has a very
large standard deviation. A review of the
dates both of the cereal grain and of the
entire site is needed, and independent verification of the cereal date required. In the
osteological study from Niuskala, no domestic animals were found. The bone
fragments were identified as seal, fish and
hare (Asplund et al., 1989). This suggests
that this settlement was mainly a fishing
and hunting site.
Three other barley grains from two sites
have been dated to nearer the end of the
Bronze Age. Two from the site Jätinhaudanmaa in Laihia have been dated to
2785 ± 30 BP (Poz-23351) and 2590 ± 40
BP (Ua-33250) (Holmblad, 2010: 135),
or 1008–844 cal BC and 831–552 cal BC,
respectively. The one from Kitulansuo has
been dated to 2990 ± 60 BP (Lavento,
1998), or 1400–1048 cal BC. However,
the grain from Kitulansuo was published
in a non-peer reviewed journal, with no
contextual information or discussion of the
665
date. The location of these sites is puzzling: Jätinhaudanmaa is remarkably far
north and Kitulansuo remarkably far
inland for such an early date; however,
barley grains directly dated to about the
same time have been recovered from
Umeå (Viklund, 2011), opposite Jätinhaudanmaa on the Swedish side of the Gulf
of Bothnia (see Figure 1). The presence of
barley grains at these sites may indicate
Late Bronze Age cultivation, but does not
necessarily prove that it took place locally:
we cannot rule out the possibility that they
could have been traded into the area.
More studies are urgently needed that
focus on this issue.
Apart from these isolated examples,
macrofossil data suggest that cultivation
began between AD 100 and 1000 in the
southwestern extremity of Finland (see
Onnela et al., 1996). Most of the sites
were excavated before Accelerator Mass
Spectrometry dating was widely used, and
so it is very likely that some dates are inaccurate. Plant macrofossil studies mainly
cover southern Finland, and in many more
northern areas, such studies are still
lacking. Thus, more detailed analyses are
needed. At the ancient field in Rapola,

Original dates from Asplund et al. (1989).
666
cereal macrofossils are dated to between
AD 780 and 1217 (Vikkula et al., 1994).
In Mikkeli, central Finland, they are dated
to AD 596–1690 (Vanhanen, 2010) (see
Figure 1 for the location of these sites).
In Finland, the earliest evidence for agriculture thus comes from the pollen record.
It is to this that we now turn our attention.
ARE SINGLE POLLEN GRAINS EVIDENCE
OF CEREAL CULTIVATION?
Most sites at which early agriculture is
claimed have only one grain of cereal
pollen. The claim that single pollen grains
are reliable evidence is based on the fact
that
self-pollinating
(autogamous)
Hordeum (barley) releases only small quantities of pollen into its immediate
surroundings (Vuorela, 1973). The pollen
is unlikely to be found, and thus it has
been claimed that every single pollen grain
provides reliable evidence of cultivation
(Vuorela, 1986; Vuorela & Kankainen,
1991; Vuorela & Hicks, 1996; Alenius
et al., 2009). Forests have an important
filtering effect on pollen, which makes it
even more difficult to find, especially in a
mosaic-like forested area like those around
slash-and-burn clearances. This has lead
Vuorela (1999: 339) to state that ‘the first
record of Cerealea pollen in pollen diagrams, in many cases, can be taken as an
indication of the beginning of agriculture’.
We do not argue against the unlikelihood
of self-pollinating plants being seen in
pollen analysis—barley pollen does not
spread in large quantities. But does this
mean that every pollen grain find is
reliable evidence of cultivation?
There are various reasons to doubt it.
We are not the first to raise these problems. In a major review article, Behre
(2007) pointed out that there are several
possible errors in the identification of
single pollen grains of cereals, such as
European Journal of Archaeology 16 (4) 2013
• reliability of identification;
• long-distance transportation of cereal
pollen; long-distance transportation of
large grass pollen;
• contamination; reliability of dating;
• reliability of anthropogenic indicators.
In summary, Behre (2007) highlights
that it is impossible to prove whether
single pollen grains are local or even from
cultivated plants at all. He argues that a
single pollen grain neither proves early cultivation nor the lack of it. Pollen analysis,
used alone, might not be the right tool to
research very small-scale changes.
IDENTIFICATION
Firstly, ‘cereal-type’ pollen does not always
mean cereal pollen! It is only a classification type, which also includes several
wild grasses. There are also several definitions as to how to distinguish cereal
pollen from wild grass pollen and how to
classify different cereal pollen types. Criteria used in early farming studies in
Finland are from Rowley (1960), Beug
(1961), Erdtman et al. (1961), Andersen
and Bertelsen (1972), Andersen (1978),
Faegri et al. (1989), Moore et al. (1991),
and Reille (1992, 1995).
Andersen and Bertelsen (1972) and
Rowley (1960) have tried to distinguish
cereal pollen types on the basis of surface
structure and exine. Rowley (1960) argues
that most cereal pollens have an incised
surface, but admits that this is not an
exclusive criterion. Andersen and Bertelsen
(1972) suggest that Hordeum vulgare
(barley), Secale cereale (rye), Triticum monococcum (einkorn), and several wild species
such as Agropyron repens, Ammophila arenaria, Elymus arenarius, and Glyceria
fluitans all have similar sculptures (i.e.
structures on the pollen surface), although
Hordeum, Elymus, and Glyceria may have
Lahtinen and Rowley-Conwy — Early farming in Finland
larger spinules. Both studies suggest that
there are insufficient differences in surface
or exine structure in wild and cultivated
grass pollen to identify individual grains.
Other classifications are listed in
Table 1, with a list of species falling into
each class in Table 2. It is clear that in
every classification there are several wild
grasses that fall into the definition of
cereal, Hordeum or Triticum type. The
classification by Erdtman et al. (1961)
does not fulfill modern scientific criteria
because the measurements of the pollen
grains (i.e. the data) on which the study is
based were not published. Erdtman et al.
(1961: 3) even state that ‘the descriptions
are definitely provisional’ and ‘the size
figures may sometimes even be misleading’. Therefore, this classification should
not be used. Andersen (1978: 91) states
that ‘the Hordeum-group includes cultivated species and some wild grasses’. Beug
(1961) proposes that wild grasses, with
few exceptions, belong to wild grass type,
and those exceptions are included in the
cereal-type group. Faegri et al. (1989:
284–85) summarize this as follows: ‘by
statistical methods it is possible to differentiate between the pollen of various taxa
if there is a sufficient number and no
admixture, but since the various curves
667
overlap, identification of individual grains
remain impossible or doubtful.’ There is
currently no method to distinguish every
single wild grass from cultivated species.
Every study is based on statistical differences and there is overlap between species
of both classes.
Modern distributions of the Finnish
wild species producing large pollen grains
have been studied by the Natural Museum
of Finland. The dispersion of wild large
pollen grain species are reported in 1 × 1
km2 (see Figure 4). The total number of
squares examined in 2011 was 7993
(Lampinen & Lahti, 2012). Two species
producing Hordeum-type pollen are found
in Finland: Hordeum murinum is known
from eleven squares, Glyceria fluitans from
no fewer than 1385 squares, which
accounts for over 17 per cent of all the
squares (Lampinen & Lahti, 2012). Pollen
grains of Leymus (previously Elymus) arenarius and Ammophila arenaria fall into
Beug’s (1961, 2004) Triticum-type, and
several wild species fall into Beug’s (2004)
category of Cerealia-type pollen (Behre,
2007). In Finland, two such wild species
are found, Setaria pumela in eleven squares
and Avena fatua from 220 squares,
accounting for nearly 3 per cent of the
squares (Lampinen & Lahti, 2012). The

Maps redrawn and modified from Lampinen & Lahti (2012)
modern distribution of Agrypyron species
in Finland is twelve squares, and Bromus
species 662 squares. Leymus species are
common not only in the coastal area (see
following discussion), but their modern
distribution covers almost the whole of
Finland (Lampinen & Lahti, 2012).
These problems have not, however,
been much discussed in Finland. Tolonen
(1984) did criticize the use of single pollen
grains, stressing that size is the only
separator between wild and cultivated
grasses. However, several wild plants
produce pollen so large that it will be considered as Cerealia-type. Other indicators
of forest clearance (e.g. Plantago major and
Chenopodiaceae) occur naturally in coastal
areas of Finland, often together with the
wild grasses that produce large pollen
grains. Therefore, it is not possible to
study the beginning of cultivation in such
places and it would be also more secure to
only use cereal pollen as evidence.
Tolonen (1984) also mentioned the possibility of long-distance transport.
Donner (1984) also criticizes studies of
early farming. He mentions the problems
of distinguishing cereal from wild grass
pollen, and argues that the solution is to
use different limits. The first, the ‘absolute
limit’, is the first occurrence of the taxon;
the second, the ‘empiric limit’, is when the
pollen curve becomes continuous; and the
third, the ‘rational limit’, is when the frequency of pollen increases. He explains
differences between the empiric and
rational limits with reference to the introduction of rye, since it produces more
pollen than other species, rather than an
intensification of farming. However, he
does not discuss whether the absolute
limit, often only based on one pollen
grain, can be considered as evidence for
local farming.
More recently Simola (2012) has criticized the paper by Mökkönen (2010) for
citing little actual evidence for early agriculture, and emphasized that there are
problems in the recognition of cereal-type
pollen.
It is important to know the local history
of the sampling site. In Finland, because
of land uplift, the coast has moved
throughout history. Single pollen grain
evidence has been used as evidence for cultivation in the Tornio area before 3500
BP (Vuorela & Hicks, 1996—citing Tikkanen, 1978). However, Tikkanen (1978)
showed that the period is clearly characterized by coastal vegetation. Wild grasses
Lahtinen and Rowley-Conwy — Early farming in Finland
producing large pollen grains, such as
Elymus and Agropyron, are common in
coastal biotopes (Reynald & Hjelmroos,
1976). The large pollen grains are more
likely to belong to these species than cultivated plants. At Merinjänjärvi, changes in
lithology (Figure 5) suggest that when the
first signals of cereal are seen, the site was
coastal (Reynald & Hjelmroos, 1980).
In such areas, pollen should not be used as
the only indicator for cultivation.
Modern pollen dispersal has been used
to evaluate whether pollen analysis can be
used to study small-scale cultivation.
Finland is a large country, and, in marginal northern areas where cultivation is
small scale, indicators of cultivation are
always sporadic. According to Hicks
(1985: 82), ‘… one cannot expect to be
able to distinguish close related activities
at this level (e.g. cereal fields from hay
fields)’. Thus, it is not possible to draw
any conclusion about the beginning of cultivation based on pollen analyses (Hicks,
669
1985). This is supported by a study where
modern pollen was used to test the representativeness of anthropological pollen
(Hicks & Birks, 1996). These modern
samples show that farms and fields cannot
be distinguished, and furthermore both
activities leave only a small amount of
pollen evidence. This suggests that it is
impossible to distinguish small-scale cultivation by pollen analysis.
LONG-DISTANCE TRANSPORTATION
Long-distance transportation is always a
problem in pollen studies. Evidence of
modern
long-distance
transportation
suggests that pollen can be transported by
storms to Fennoscandia from as far away
as North Africa or North America
(Franzén & Hjelmroos, 1988). Studies of
coloured snow from southern Sweden
found that Hordeum-type pollen, together
with that of other plants usually regarded

lake (i.e. gyttja), and finally the development of the bog. The coastal stage is marked by the presence of
large size grass pollen falling into the definition of Cerealia-type.

as cultural indicators, including Plantago
lanceolata and Urtica (nettle), is part of
such particle movements. The source of
such pollen is impossible to trace absolutely, but mineral grains and plants
suggest that the origin was somewhere in
Denmark, at least 200 km away from the
sampling site (Franzén & Hjelmroos, 1988).
Pollen can travel not just hundreds of
kilometres, but also thousands. Samples
collected from the snow surface in close
proximity to the Arctic Circle in central
Sweden show this. Cerealia-type pollen
was found, mainly Secale-type and
Triticum-type. The closest area where
cereals flowered before the time of
sampling was Italy, and mineral particles
even suggest North Africa. These data
suggest that drawing conclusions from
single pollen grains should be avoided
(Hjelmroos & Franzén, 1994).
DATING
AND
INTERPOLATING PROBLEMS
Simola (1999) has pointed out that
Vuorela and Hicks (1996) used pollen evidence uncritically and have used
radiocarbon dates for early agricultural
activity without any discussion of
reliability of the results. Many of their
radiocarbon dates come from bulk sediment samples. Simola states that the
possibility of old carbon is not considered,
and that the dating results are not even
discussed. Bulk sediment was often used
to date pollen cores in the 1970s and
1980s. It has been shown that such results
can be in error by thousands of years (Barnekow et al., 1998; Grimm & Nelson,
2009; Stanton et al., 2010). This has long
been known in Finland: Tolonen et al.
(1976) showed that radiocarbon dates
from several lakes in southern Finland are
500–800 years too old compared with
known rates of land uplift or annual
varves. Several other Finnish studies have
produced similar results (Huttunen &
Tolonen, 1977; Tolonen, 1980a, 1990).
Tolonen et al. (1976) accepted that such
dates are estimates and should not be considered as absolute dates. Therefore,
estimating the beginning of farming
should be based on several dates and
results from several sites, and one must
accept that some of the sites will give
dates that may be too old. In another
study, Pitkänen and Huttunen (1999)
compared radiocarbon dates on leaves and
sticks from Betula (birch) with annual
varves from Lake Pönttölampi. The results
showed that the radiocarbon dates were
500–1100 years older than the varve ages.
Thus, any results should be considered
with considerable caution.
In some studies, the layer with early
farming evidence is not itself dated. Often,
in pollen analysis, age-depth models based
on sedimentation rates are used to place
the results on a chronological scale, and
ages for particular horizons are interpolated or extrapolated. One study
compared such an age-depth model based
on six radiocarbon dates to a lake’s annual
varves, and concluded that the age-depth
model was in error by as much as 90–180
years (Telford et al., 2004). Most of the
earlier studies in Finland used only two to
four dates, and the samples spanned
several years of sedimentation. Thus, it is
very likely that in reality the errors are
even greater. One major problem with
extrapolating dates occurs when the latest
radiocarbon date comes from below the
level under consideration: the sediment at
the surface is always recent and the sedimentation rate is fastest. To be able to
interpolate, it is necessary to distinguish
where the sediment ends (i.e. which is the
topmost layer), which is always an estimation. In many cases, error limits are not
even discussed and thus the uncertainty of
the study is not known, which makes
comparison of the studies more unreliable.
Lahtinen and Rowley-Conwy — Early farming in Finland
THE SPRUCE DECLINE
AND
FOREST FIRES
A decline in Picea (spruce) has often been
used as evidence for cultivation, because
the occurrence of single cereal-type pollen
grains, other cultural indicator species,
high levels of charcoal and the introduction of spruce often appear together in
pollen diagrams. The explanation offered
for this is that slash-and-burn cultivation
worked well in spruce forests (Vuorela,
1986). However, in Finland, such cultivation has been practised until recently, and
the most suitable forest type was in fact
Betula-Alnus (birch and alder) forest aged
about 15–30 years old (Heikinheimo,
1915).
Grönlund et al. (1992) used the spruce
decline as evidence of a local forest clearance phase, and together with single
pollen grains as an indication of early agriculture. Vuorela (1986) has even suggested
that the decline of Picea pollen is the only
indicator of early clearance for cultivation.
However, it is not possible to distinguish
between natural and anthropogenic fires,
although fires are often visible in pollen
diagrams before cereal pollen occurs.
Natural fires do occur: Larjavaara et al.
(2005) show that lightning can cause a fire
in boreal forest.
A connection between spruce and cultivation is not accepted by all.
Rowley-Conwy (1983) argued that a
spruce decline can be explained without
connection to human activity. His main
point is that ‘fire is a natural component
of spruce forest ecology’ (Rowley-Conwy,
1983: 206), and the so-called cultural indicators originate naturally in the area.
A study from northern Sweden supports
the idea that fire is an important element
in spruce-dominated forest (Hörnberg
et al., 2012). Similar results between spruce
and fire connections are seen in boreal
forests in Canada (Black & Bliss, 1980).
Spruce did not spread in close proximity to
671
swamps where fires were absent even if it
was present in the area (Segerström et al.,
2008). In Finland, Mökkönen (2010)
pointed out that the introduction of spruce
does not correlate with the spread of the
CW culture. If this culture did practice cultivation, as Mökkönen (2010) assumes, the
appearance of spruce therefore cannot be
explained by cultivation.
Fire-interval studies have been made in
the context of early cultivation studies.
Huttunen (1980) reconstructed fire intervals in southern Finland. There were
several changes in frequency. From AD
470 to 1100 mean frequency was 95 years;
from then until AD 1600 the mean interval was 57 years; and between AD 1600
and 1900 it was 30 years. A continuous
cereal pollen curve started around AD
1500. Similar results can be seen in
eastern Finland, where the fire interval
between the seventeenth and nineteenth
centuries was around 30–40 years after the
start of cultivation, and 100–200 years
before that (Lehtonen, 1998; Pitkänen &
Huttunen, 1999). In eastern Finland, a
study of charcoal particles showed intervals
of 320–520 years without a clear spruce
connection. However, sampling did not
reach to the modern surface, so this evidently reflects the natural fire frequency in
boreal forest, not one caused by agriculture
(Pitkänen et al., 2003a). Another study
supports this: in eastern Finland, intervals
are approximately 170–240 years until AD
1500, and, after that, approximately 50
years (Pitkänen et al., 2003b). More
recent studies suggest longer intervals.
In northern Swedish Lappland, fire intervals
fluctuated between shorter (approximately
200–300 years) and longer (approximately
500 years) periods. This in fact correlates
better with climatic fluctuations than
archaeological data (Caseldine et al.,
2008). It is doubtful whether agriculture
played any important role at all in such
northern areas.
672
European Journal of Archaeology 16 (4) 2013
In sum, it seems that fire intervals
might have decreased after cereal cultivation started. Cultivation would also
explain why there are differences between
regions. In northern Finland, where cultivation was not possible, slash-and-burn
cultivation was never practised and fire frequency stayed low. In southern and central
Finland, the evidence suggests the opposite to what has previously been argued.
There is no evidence that slash-and-burn
cultivation was practised in the early stages
of cultivation. Furthermore, it was probably never important in the western part of
the country. Thus, the spread of agriculture into eastern Finland might have been
affected by the late innovation of fast-cycle
slash-and-burn cultivation. However, more
studies are needed from the western part
of the country.
WHAT DO
THE
POLLEN DIAGRAMS TELL
US?
On the basis of the arguments put forward
in the previous section, it is questionable
whether pollen provides any evidence concerning the beginning of cultivation in
Finland. It might be a more recent innovation in Finland than has been previously
suggested. Pollen studies that have been
suggested to support the presence of early
cultivation before the Iron Age are discussed here.
Stone Age cultivation before 1500
cal BC
The only evidence for this period is in the
form of single pollen grains found at
various sites around Finland. Seventeen
examples are mentioned by Vuorela and
Hicks (1996) and Mökkönen (2010).
These are listed in Table 3, and plotted in
Figure 6 (top).
As we have discussed, method of identification is important. The studies of the
sites of Lamminjärvi, Lalaxkärret, and
Humppila, Vasikkasuo and Karvalammi
do not publish the criteria used for cereal
pollen recognition (Tolonen, 1980a,
1980b; Aalto et al., 1985; Vuorela, 1990).
At Könttärinlahti, a size criterion of 42
µm is mentioned and at Vasikkasuo, 41
µm is used, but at Könttärinlahti, the
pollen is said to be Hordeum-type (Vuorela
& Kankainen, 1991; Vuorela, 1994). In
Northen Ostrobotnia, size (greater than
45 µm) and pore size (greater than 8 µm)
were used to identify cereal-type pollen
(Reynald & Hjelmroos, 1980). At Kankareenjärvi and Preittilänsuo, Beug’s (1961)
criteria were used. However, Kankaanjärvi
was dated using bulk sediment dating, and
it has already been mentioned that such
dates are probably too old. Two cerealtype pollen grains (type is not mentioned)
were found in different layers at Preittilänsuo (Tolonen, 1987); these could just as
well be large wild grasses. At Katajajärvi,
modern methods of morphology and size
are used, and one Hordeum-type pollen
grain was found in the Stone Age layers
(Alenius et al., 2009). A similar situation
is seen at Kemiö where one Hordeum-type
pollen grain and one Secale-type pollen
grain occur in Stone Age contexts
(Alenius et al., 2008).
The most recent claim to find
Hordeum-type pollen is by Alenius et al.
(2013) from southern Finland. This paper
published the criteria utilized. One grain
of Fagopyrum esculentum (buckwheat) was
dated to 6276 ± 55 BP (5369–5063 cal
BC). It is possible for such large grains to
travel long distances; also the possibility of
modern contamination has to be considered with this single pollen grain. In a
study like this, where the minimum
number of pollen grains counted is 1100,
it is much more likely that rare large size
grass pollen grains will be recorded. Three

Figure 6. Maps showing distribution of pollen sites with cereal-type grains. Top: Stone Age, sites
numbered as in Table 3; bottom: Bronze Age, sites numbered as in Table 4.
The only continuous pollen curve
claimed from the Stone Age is from Lake
Kankareenjärvi in southwestern Finland,
dated to 3530 BP. However, the author of
the study has stated that compared to
other studies in the region, the date is
likely too old. Dating was done on bulk
sediments, which are probably contaminated by old carbon. Furthermore, the site
is coastal, and thus some large cereal-type
pollen from wild grasses growing in these
habitats should be expected.
Reynald and Hjelmroos (1980) studied
six sites in the northern Ostrobotnian
region. Every one of the sites shows evidence of cereal-type pollen. This has been
used without any criticism as clear evidence of farming. However, most of the
sites were coastal, and have scattered
cereal-type evidence from the time the
rising land caused the isolation of the lake.
The large-grained wild species Elymis arenaria and Agropyron canina are common
species in the area (Reynald & Hjelmroos,
1976), so any evidence should be treated
very cautiously. Levels of cereal pollen
were low and sporadic in every diagram,
and no change from a natural to a farmed
landscape can be seen. Radiocarbon dating
in the area is problematic because of the
recycling of old carbon. In the absence of
any other source of evidence, it cannot be
Lahtinen and Rowley-Conwy — Early farming in Finland
determined when cultivation first occurred.
Historical sources suggest that it could be
as recent as the medieval era (Luukko,
1954).
Bronze Age cultivation (1500–500 cal
BC)
There are several sites that have claimed
evidence of Bronze Age cultivation. They
are listed in Table 4 and plotted in
Figure 6 (bottom)2.
There are only four sites with more
than single pollen grains. They are Aholanlammi (Koivula et al., 1994),
Loimaansuo (Vuorela, 1975), Antinlampi
(Vuorela et al., 1993), and Kissalammi
(Tolonen, 1981). At Loimaansuo and
Antinlampi, the identification criteria were
not published. One single Hordeum-type
pollen grain from Antinlampi is stated to
be as large as 60 µm. According to Faegri
et al. (1989) this should apparently be
classified as Elymus-type, although, since
other criteria are not mentioned, this is
not completely certain. Because of this, it
is not possible to consider the pollen
grains from these sites as reliable evidence.
At Aholammi, evidence is put forward
for Bronze Age cultivation. A continuous
cereal-type pollen curve starts after
3460 ± 90 BP (Koivula et al., 1994), or
2019–1531 cal BC. The radiocarbon dates
have, however, been done on bulk organic
material, which includes all organic
material found in the sediment; therefore,
the date should be considered only very
cautiously. The dating of the layer is the
latest date in the core, so it is not known
how accurate it is (see earlier discussion).
The sample for radiocarbon dating was a

10-cm slice, which itself will cause great
error limits (Koivula et al., 1994).
At Kissalammi, Cerealia-type pollen
appears as early as 3940 ± 110 BP (2864–
2135 cal BC) but there are never more
than one or two pollen grains (Figure 7).
These pollen grains appear in the pollen
diagram as Cerealia-type, but in the published text it is stated that ‘in the last part
of QM-3060 ± 120 BP [1608–979 cal
BC] Cerealia pollen grains, viz. Hordeum
and Triticum types was connected with
cultivation in the vicinity of the site’
(Tolonen, 1981: 217). It is not evident
how many pollen grains from each genus
were determined, or whether some grains
were just of cereal type. The total amount
of cereal-type pollen increases from 500
varve BC onward. The study was carried
out by counting 1500 arboreal pollen
grains per sample (Tolonen, 1981); this
large total increases the likelihood that
wild large-pollen species or long-distance
transportation grains will be found. There
is also one cereal-type pollen grain before
the Bronze Age, so it is likely that some
large-grain wild species grew near the site.
In northern Finland, only a limited
number of studies have been done. Small
amounts of cereal-type pollen are found at
almost every site. Tikkanen (1978) states
that coastal vegetation can clearly be seen
in the diagrams, and this will include wild
grasses with large pollen grains. Thus, it is
not possible to say whether the cereal-type
pollen really comes from cultivated cereals.
As already mentioned, cultural indicators
are common in such an environment.
As discussed in the Stone Age section,
there is similar evidence in the study by
Reynald and Hjelmroos (1976) from
several sites in the northern Ostrobotnian
region, so this evidence is not conclusive.
However, it has been used to support the
hypothesis that cultivation started in
northern Finland soon after it began in
the southern part of the country (Vuorela

CONCLUSIONS
Pollen analysis is a useful tool, but is not
an absolute method for determining the
presence of agriculture. Wild grasses can
produce pollen of cereal-type, Hordeumtype, and Triticum-type. Consequently,
any evidence derived from single pollen
grains is always questionable. As there is
not enough reliable evidence to support
agriculture in Finland before the Iron Age,
we conclude that more studies using
different lines of evidence are required
before Stone Age or Bronze Age cultivation can be proposed.
The evidence from Finland thus takes
its place alongside that from most of the
rest of Europe. The early pollen claims for
cereal cultivation are anomalous, and
increasingly out of line with all the other
sources of evidence for agriculture. Finland
acts as an important test-case for Europe
as a whole: since prehistoric agriculture
was a marginal economic activity so far
north, the pollen claims focus attention on
the issue across the continent. Future
work by Finnish archaeologists on the
date of the earliest agriculture in Finland
will be of continental significance.

sur des analyses polliniques; quelques-unes remontent jusqu’à la période néolithique. Nous évaluons de
façon critique ces affirmations et avançons que les grains de pollen de type ‘céréales anciennes’ pourraient
très bien provenir d’herbes sauvages à gros grains, et, en l’absence d’autres preuves, ne sauront pas servir
comme preuves évidentes pour la culture de céréales. Il se peut que la culture des céréales en Finlande
n’ait commencé qu’au début de l’Âge du Fer vers 500 BC. Translation by Isabelle Gerges.

Frühe Landwirtschaft in Finnland: Hat es dort Pflanzenanbau vor der Eisenzeit
(500 v. Chr.) gegeben?
In diesem Beitrag werden die frühesten Belege für Landwirtschaft in Finnland untersucht, die sämtlich
auf Pollenanalysen beruhen und teilweise sogar Datierungen bis ins Neolithikum beanspruchen. Diese
Ansätze werden kritisch untersucht und es wird vermutet, dass diese Pollenkörner ‘früher Cerealientypen’ eigentlich von langkörnigen Wildgräsern stammen und bei Abwesenheit anderer Belege nicht als
klarer Beweis einer Kultivierung angesehen werden können. Die Kultivierung von Getreide wird erst
zu einem späten Zeitpunkt, dem Beginn der Eisenzeit um etwa 500 v. Chr., begonnen haben. Translation by Heiner Schwarzberg.
