demonstrated that the displacement of native annuals by Mediterranean annual grasses in California may largely have been driven by cattle grazing.

Litter removal affected forest nutrient cycling and productivity less than expected, probably because the soil at the site is moderately fertile. However, litter addition increased litterfall indicating that some limitation of forest production was removed by litter addition.

Mediterranean climate ecosystems in other regions have nutrient-poor soils similar to our subtropical Florida sites, but show post-fire seedling recruitment patterns more similar to the nutrient-rich sites in California. Climate therefore appears to play a more major role than soil characteristics
