Here are a few reasons why:
- Mowing or close grazing removes all the vegetation, while prescribed burning leaves some behind. This can be important for maintaining soil health, as well as providing food and shelter for wildlife.
- Mowing or close grazing can damage the root systems of plants, while prescribed burning does not. This can make plants more susceptible to drought and other environmental stresses.
- Mowing or close grazing can create a thatch layer on the ground, which can prevent water from infiltrating the soil. This can lead to runoff and erosion, as well as making it more difficult for plants to establish themselves.
- Prescribed burning can help to control invasive species, while mowing or close grazing can actually spread them. This is because invasive species are often more competitive than native plants, and they can take advantage of the disturbed conditions created by mowing or close grazing.
In general, prescribed burning is a more sustainable and beneficial way to manage rangelands than mowing or close grazing.
