A Synthetic Review of Feedbacks and Drivers of Shrub-Grass Interaction in the Process of Grassland Shrub Encroachment.

Many grasslands around the world are affected by shrub encroachment. The essence of shrub encroachment into a grassland habitat is a change in the direction and intensity of shrub-grass interactions, which leads to an alteration in the grassland community structure. Recent research progress can be summarized as encompassing the primary factors influencing shrub encroachment and the physical, biological, and chemical ways through which they affect grassland community succession and shrub-grass interactions.
