Description
Summary:We conducted a field experiment in which small mammal density was manipulated at three replicate sites near Toolik Lake, Alaska. The motivation for collecting this pointframe dataset was to understand and quantify the impact of the most abundant herbivores, small rodents (voles and lemmings) on tussock tundra vegetation community composition and canopy structure in the Arctic. In July of 2018, at each site we set up an 8 meter (m) x 8 m fenced exclosure with a 0.635 centimeter (cm) square mesh to prevent herbivore grazing and increase vegetation cover (Exclosure treatment (EX)), set up a 20 m x 20 m enclosure that was stocked with up to 4 voles from spring snowmelt through September in 2018 and 2019 (Press treatment (PR)), and identified an 8 m x 8 m unfenced control plot marked at each corner with pin flags at each site (Control (CT)). In 2019, at each site we set up a 20 m x 20 m enclosure that was stocked with up to 4 voles from spring snowmelt through September in 2019 only, after which voles were ...
