Hampton-Miller CJ and Neitlich PN. 2024. Grazing exclosures in Bering Land Bridge National Preserve: 2012-2022 data report. Natural Resource Data Series. NPS/BELA/NRDS—2024/1406. National Park Service. Fort Collins, Colorado. https://doi.org/10.36967/2302594
To monitor the impact of grazing by caribou and other ungulates on vegetation in Bering Land Bridge National Park, 17 exclosures were installed in the summer of 2012 and one in 2007. These exclosures consist of 9 by 9 m of chainlink fencing, which prevented grazers from reaching vegetation plots within. Two plots within the fencing were paired with two unexclosed plots outside the fencing. All plots were measured in 2012 for lichen, bryophyte and vascular plant cover and species composition by point intercept methods. The first remeasure of the plots took place in 2022. This report summarizes the purpose of the exclosures, the methodology, changes to the methodology over time, the data structure of the database and preliminary results of re-measure data collected in 2022.
