Part of my research on Mount Saana is how the effects of increased nutrients on tundra plant communities depend on the presence or absence of herbivores. In the past I’ve worked in areas with cattle and elephants, but the dominant herbivore in this system is reindeer. Our first two weeks in Finland we saw a few reindeer wandering on the roads and in campgrounds. This week, a herd of hundreds moved into this area, including up and down the mountain where we work. It’s been incredible to see them in the forest, wandering on the steep cliffs, and even grazing in our study plots!
