Our study focused on land cover in Käsmu peninsula, located in the north coast of Estonia in
Lahemaa National Park. We wanted to find out what kinds of land covers can be found along
the way and whether Käsmu peninsula is a homogenous site regarding MUC code and land
cover or not. In addition, we were interested in how different kinds of vegetation alter the
temperature change along the journey and how does the temperature/humidity change related
to the elevation and land cover (e.g. peatland VS sandy pine forest; developed VS natural
sites).
In our expedition on August 3rd 2022, we investigated two study areas (sized 30 times 30
meters) that were at two different spots. First site was located in a sparse pine forest, on dry
sandy soil, under the pine trees and covered with blueberries. Second spot was on a humid
peatland, which was covered with peat moss and marsh Labrador tea (Rhododendron
tomentosum).
We used different methods to examine tree heights, temperature, humidity and other figures.
Work was divided between the expedition team members. In conclusion, we were not too
surprised with the results as the areas examined were not very far away from each other and
differences in land covering plants was not major. We hope that our data will be useful to
other people such as locals for knowing their area better and scientists to get a better and
more precise overview of Käsmu peninsula.
