Description
Summary:We conducted a field experiment in which small mammal density was manipulated at three replicate sites were set up in tussock tundra near Nome, Alaska(AK). The motivation for collecting this Normalized Difference Vegetation Index (NDVI) dataset was to understand and quantify the impact of the most abundant herbivores, small rodents (voles and lemmings) on dynamics of canopy productivity on tussock tundra vegetation communities 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)). Within each treatment at each site, we measured NDVI at 8 distinct locations within each quadrat and subplot ...
