Gelbard‚ Ph.D. Department of Environmental Science and Policy‚ University of California‚ Davis THE STRUCTURE AND FUNCTION OF the world’s grasslands makes them one of the most vulnerable to global climate change of any terrestrial ecosystem (Sala et al.‚ 2000; IPCC‚ 2001a). The low-stature of vegetation confers high light availability‚ leaving many grasslands naturally vulnerable to invasive species (Wagner‚ 1989)‚ especially following disturbance (Hobbs and Huenneke‚ 1992).
