The ecological role of and survival threats to grassland rodents

Grassland rodents are an indispensable part of grassland ecosystems and play an important role in maintaining and optimizing the function of grassland ecosystems. However, these rodents are threatened by the grassland management departments that often focus on the negative effects of grassland rodents and ignore or seriously underestimate the ecological role that they play. Therefore, this paper describes the key grassland rodent species and their ecological role in grassland ecosystem engineering, and summarizes the threats that they are currently facing (including the effect of habitat loss, population killing, disease and alien species invasion and climate change), thus providing a reference for grassland rodent management and protection.
