A walk in the snow

This week, I was in the field to train two students and find potential new field sites. The training was successfully done in decent weather, a mix of sun and clouds. But when we started to walk up the mountain, the snow came. It was snowing and hailing and raining, all in one.

We found a beautiful summer farm, where I will have one of my field sites. It even has a letter box, where hikers can write their names when walking up the mountain.

I’ll have to come back to select the sites properly, set up plots. And then I will spend a lot of time staring at the plants. Looking forward to this!

First field day – THREE-D

A couple of weeks ago, I went to the field for the first time in the THREE-D project. In this project, we want to disentangle the impact of different global change drivers on biodiversity and the carbon cycle. We need to select new sites and set up the whole experiment this summer in western Norway and eastern Himalaya in China.

This first round was to set up grazing exclosures. We want to get and estimate of the grazing intensity along the elevational gradients, to know how much biomass is removed over the growing season. For this, we put up metal cages, that will exclude large herbivores and this will be compared with control plots without cages. The biomass in these plots will be harvested, dried and weighed. A master student will work on this project in Norway this summer.
