Arctic LTER terrestrial research conducts long-term, whole-ecosystem experimental manipulations of factors related to climate change including N+P factorial fertilization, greenhouses with and without N+P fertilization, and shade houses in the major tundra types around Toolik Lake.  In addition mammalian herbivore pressure has been experimentally altered in moist acidic (MAT) and heath tundra to examine the role of herbivores.
