Satellite view of the KLEE exclosure plots in Laikipia, Kenya, where we have been excluding various combinations of cattle, wildlife, and mega-herbivores (elephants and giraffes) from a savanna grassland since 1995.  Each of the 18 plots is 200m x 200m.  This is an NDVI false-color image taken 20 June 2003 (Quickbird, via Digital Globe). Redder areas are indicative of higher productivity.  The larger red areas are anthropogenic glades, and the smaller red areas are low termite “mounds”.  Both are hot spots of soil fertility, plant productivity, and animal use.
