Future of Grasslands

Global change defines how every abiotic and biotic factor along with ecological process's on our planet can or is changing, some of these changes may include increasing CO2 levels, wildlife and vegetation migration, transitioning of ecosystems into new alternate stable states and phases, and many more factors. Basically its how all of our planets systems can or are changing. I think global changes biggest affect on grasslands will be increasing temperatures or changes in the precipitation regime. Basically any type of change that is going to alter a site and possibly better support other vegetation. For example, say the precipitation regime changes and the grasslands are getting more rain than average, decreasing the fire frequency. The change in fire regime could allow woody encroachment or provide a habitat for non-native species, causing the ecosystem to start to shift to a tree, shrub, or non-native dominated ecosystem. Another impact on global change is that land managers cannot do anything about a changing temperature or precipitation regime, so the change would not be preventable in that case. Temp and precip are just two of the many examples that come with global change and its possible affects on grassland ecosystems. Feel free to comment down below if you guys think of other examples!
