Work Packages

Work Package 1: Predation and the dynamics of arctic-alpine food webs

To determine the potential of rodents to control vegetation biomass along a coast-inland gradient and a primary productivity gradient. Rodent impact will depend on variation in predator abundance.



Work Package 2: Impact of vertebrate herbivory on tundra vegetation

To study the combined direct and indirect impacts of herbivores and climatic factors on plant communities and ecosystem processes on tundra.



Work Package 3: Impact of grazing on the dynamics of rare arctic-alpine plants

alppiruusu.jpgTo determine the core areas of Fennoscandian arctic-alpine plant diversity and assess their conservation status in current and future climates. In addition, we explore whether positive impacts of reindeer activity can help to preserve this diversity in a changing climate.



Work Package 4: Moth-reindeer-birch dynamics in northernmost Fennoscandia
Lappland II 070.jpg

To quantify the impacts of grazing and browsing by reindeer and small herbivores on forest regeneration and plant and soil communities following moth outbreaks using experimental herbivore exclosures.



Work Package 5: Large scale impacts of herbivory on vegetation
Lappland 2006 - Teil I 099.jpg

To produce large and medium scale vegetation maps covering all areas in Northern Fennoscandia. In addition the work package aims to evaluate greenness, productivity and carbon exchange for dominant vegetation communities.



Work Package 6: Ecology and socio-economy of
reindeer herding systems porot.jpg

To study how past and present Sámi reindeer herding practices have affected shrub cover and how the majority societies have interfered with these processes. Can the goals of reindeer owners and the conservation of tundra ecosystems benefit from each other?


Work Package 7: Interaction between vegetation and climate

wp6.jpgTo investigate how reindeer affect the ground surface and climate. We have noticed that by altering the vegetation density and height, reindeer have influence on snowmelt timing as well as ground reflectance and heating.


Work Package 8: Abiotic processes, spatial information (GIS), synthesis and policy recommendations


T
o combine the results of other teams with existing information to produce knowledge and GIS databases on Fennoscandian tundra ecosystems and the processes of climate change. This supports the adaptation to the impacts of warming climate and will be done in collaboration with reindeer herders and authorities.
