How do droughts affect the savanna?
“Trees can benefit from how much drought reduces grass — which competes for resources with the trees and fuels savanna fires.” Researchers say it is important to understand the ecosystem’s response to droughts, which are expected to become more frequent and severe with global climate change.
Are there droughts in the savanna?
Droughts are a periodic feature of these savanna ecosystems, but under current management regimes wild ungulate populations are often kept within hard boundaries and there are limited options for ungulate migration.
What is the biggest threat to the savanna?
Around the world, savannas are threatened by human actions like logging, development, conversion to agriculture, over-grazing by livestock, and introduction of non-native plant species.
What would happen to a savanna that experienced a decrease in rainfall?
When there is a deficit of rain, the trees suffer less than grasses and therefore win out. The Princeton research suggests that these global climate changes will eventually lead to a reduced abundance of trees on the savannas.
Why is the savanna worth saving?
Why are Savannas important to protect? Savannas are important to protect because they are rich in biodiversity. They are home to some of the world’s most exotic animals and birds. Savannas are located in migration corridors of animals and birds and contain some of the world’s largest watersheds.
How do humans impact the savanna?

Do humans live in the savanna?
