What are some limiting factors of Grasslands?

• Answer:

  Rain as a portion of the climate is a limiting factor. Temperate or high latitude grasslands include veldt, tallgrass prairie, & pampas with more than 20” rain/year. Other temperate grasslands are short-grass prairie & steppes that receive less than 20" rain/year. http://www.plantsystematics.org/reveal/pbio/biome/grea.html Fire is a factor. Temperature - seasonal range. Bedrock that provides the minerals for the soil. Savannas form the soil by laterization resulting in the top soil layer being very thin compared to a temperate pampas or steppe that has deep fertile soil formed by calcification. Some of the main influences in soil formation are the higher temperatures and the concentrated rainfall due to latitude and topography. How the bedrock weathers creates the soil.
