Reindeer on Mt. Saana

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!

I have a really cool job where I get to spend my summers in beautiful places, hiking and looking at plants. I’ve done work in the Elwha river valley, Sierra Nevada mountains, burned California shrubland, Kenyan savannah, and more. I study how plants respond to disturbance—fire, drought, dam removal, build up of nutrients—and how those responses are shaped by other plants and by herbivores.

This summer, I’m working somewhere I’ve always wanted to go–Finnish Lapland–studying tundra plants. The project is testing how plant communities recover from years of added nutrients. It’s amazing to be so far north (the sun never sets! also, the sun never sets) in a patchwork landscape of mountains and lakes. And the tundra—the plant community itself—is incredible.

This is Mount Saana, where I’m working. From a distance, the area above the trees looks like a homogenous greenish-brownish blur. But get closer, and more and more variation reveals itself in the patchwork of ankle-heigh shrubs. Even closer, and stunning flowers pop out in all colors and shapes. Here’s a picture of one of our study plots—just a mere 25 cm x 25 cm—with 13 species growing in it!
