The war on deciduous forest
At the mid-twentieth century the pace of the transformation of the Swedish forest increased. New methods; large-scale clearcutting, mechanization of logging and planting of seedlings were developed. Chemicals were used to control insects and unwanted tree species. The aims of this study were to elucidate the timing, chain of events and the spatial extent of the large-scale spraying of phenoxy acids in Swedish forests and the drivers for this prac…
Anthropogenic use of fire led to degraded scots pine-lichen forest in northern Sweden
Northern pine-lichen forests are generally regarded as natural ecosystems that, in the past, were repeatedly affected by wild fires. This paper presents and tests a new hypothesis that reindeer herders used recurrent fires to promote and sustain reindeer lichen-dominated ground vegetation, in order to maintain good winter-grazing grounds in Scots pine forests. We investigated vegetation and fire history in three pine-lichen forests along the Lule…
Heat impact and soil colors beneath hearths in northern Sweden
Cereal cultivation from the Iron Age to historical times
For several decades researchers have debated when cereal cultivation was introduced to northernmost Europe. Most previous studies have concentrated on sites along the coast or close to major rivers; these are areas well-suited to agriculture and represent routes for people and knowledge transfer, but omit other vast areas suitable for cultivation and sedentary settlement. Here, we present strong evidence of permanent cultivation from ad 480 onwar…
Indications of shifting cultivation west of the Lapland border
Permanent cultivation is generally believed to have been established in the interior of northernmost Fennoscandia later than elsewhere in northern Europe, during or after the late 17th century. Although subtle evidence from various pollen records suggests cultivation may have occurred much earlier in this region, such indications have generally been disregarded. We hypothesized that cultivation was introduced early in the Lapland border zone wher…
Intensive land use in the Swedish mountains between AD 800 and 1200 led to deforestation and ecosystem transformation with long-lasting effects
Early Cereal Cultivation at Sami Settlements
It has been generally accepted that cultivation in northernmost Sweden was intrinsically associated with the migration of Nordic farmers into the area and that indigenous Sámi societies followed purely hunter-gatherer or pastoralist subsistence strategies. In this paper, it is argued that the discursive connotations of cultivation have promoted a dichotomy between Sámi and Swedish idioms that are still being reproduced among scholars, as well the…
Revealing the cultivation history of northernmost Sweden
Archaeological and historical records suggest that cultivation became established rather late in northern Fennoscandia, preferably in coastal villages of northernmost Sweden during the 14th century. The expansion of these settlements has obliterated the relevant biological archives, thus restricting our ability to conduct palaeoecological studies of the oldest villages and limiting our knowledge of their cultivation history. In a secondary phase,…

Historical land use and resource depletion in spruce-Cladina forests of subarctic Sweden
Woody vegetation, fuel and fire track the melting of the Scandinavian ice-sheet before 9500 cal yr BP
New studies indicate the presence of early Holocene ice-free areas far north in Scandinavia. Post-glacial fire and vegetation were investigated based on sedimentary charcoal and pollen from two small lakes in northern Sweden. Accumulation of organic sediment started around 10,900 and 9200 cal yr BP, showing that both lake valleys were ice-free extremely early given their northerly location. Fire events started after 9600 cal yr BP and became less…
Fire as an important factor for the genesis of boreal Picea abies swamp forests in Fennoscandia
The initial establishment of Picea abies in Sweden and Norway on a landscape level, between 3000 and 1000 years ago, was often preceded by recurrent fire and thereafter the influence of fire decreased. However, in some swamp forests, the absence of fire over the last 3500 years has promoted the continuous presence of deciduous trees, i.e. Picea has not established although it has been present regionally for over 3000 years. Our objective was to s…
A thousand years of human impact in the northern Scandinavian mountain range
The vegetation history has been examined by pollen, microscopic and macroscopic charcoal analyses in the vicinity of two alpine Stállo settlement sites and one forested ‘Reference area’ with no settlement remains in northwestern Sweden in the northern part of the Scandinavian mountain range. The acquired data provide indications of the effects of human activities on local vegetation during the settlement phase, and on ecological processes in both…
Long-term sustainability of a northern boreal deciduous swamp forest in northern Sweden
In Fennoscandian boreal forests the general succession pattern after a stand-replacing fire includes the pioneer tree species Betula, Populus, Salix and Pinus. The primary colonizers are subsequently replaced by secondary species; on mesic and moist soils commonly by Picea abies. Many swamp forests have developed from deciduous Betula/Alnus fens to Picea abies swamp forests during the last 3500 years, since Picea became common in this region. Our…
Vegetation development at a mountain settlement site in the Swedish Scandes during the late Holocene
Long-term vegetation changes in the northern Scandinavian forest limit
A palaeoecological study was performed in the northern Scandinavian mountain range in Sweden. The aim was to study vegetation changes and shifts in forest limit altitudes during the last 5000 years in a tree-less archaeological site (Adamvalta) situated below the regional forest limit, and in a forested reference area with similar geological features but without archaeological evidence of human presence (Ajdevaratj). The suitability of uncritical…

The 9000-year histo of vegetation development and disturbance patterns of a swamp-forest in Dalama, northern Sweden
Analysis of pollen and charcoal in peat cores together with age-structure data of a swamp- forest site in the western part of central Sweden show the regional vegetation succession and the disturbance patterns over the last 9000 years. Five major vegetation sequences are identified: 1) Betula- Pinus period (c. 7000 to c. 6000 cal. BC); 2) wetland development (c. 6000 cal. BC to c. cal. AD 300); 3) Picea swamp-forest establishment ( c. cal. AD 300…
