what are some threats to a savanna
Threats to Biodiversity. The primary threats to the savanna biome are humans (for example, poachers are killing elephants for their ivory tusks and hunting animals to the brink of extinction) and global climate change.
One threat to these Savanna biomes is the animals which graze upon it. Other biomes such as Taiga or Rainforest have a high tree quantity which means that less grass is able to grow for animals to graze on. However, since Savannas have few trees and much wide open space than other biomes an herbaceous layer grows much easier.
