Biological Control of Non-native Invasive Annual Grass Species

Here is an experiment from RLS on Texas Rescue Grass, Bromus Cartharticus, which is an annual non-native invasive grass. It behaves similar to Cheat Grass, Bromus Tectorum. They both love bacterially dominated soil systems and are early successional plants that thrive in damaged or disturbed areas.

With the use of Provide and Revive, tools for increasing microbial balance, we were able to shift the fungal bacterial ratio and increase fungal activity to selectively discourage the invasive annual Bromus grass and encourage desirable perennial grasses. This is one test of many and we are excited to help others!

Professor David Johnson has been working on this same idea. Here is a slide from his presentation that illustrates how the fungal to bacterial ratio affects the plant community. If you want your desired plants to thrive, you will need to make sure you have the ideal soil microbial community.
