Knowledge about Plant Coexistence during Vegetation Succession for Forest Management on the Loess Plateau, China

Coexistence between species within plant communities is a key issue in the practice of revegetation, forest management, and biodiversity conservation. Vegetation restoration critical to control soil erosion improve ecological environment on Loess Plateau. Here, we investigate interspecific relationships dominant plants during natural vegetation succession The results suggest that, under process environmental filtering, can reduce competition promote coexistence via spatial heterogeneity temporal asynchronous differences. niche overlap index (Oik) significantly positively correlated with strength associations. Most pairs had weak more stable relationships. χ2 test showed that 317 were associated 118 negatively associated. community positive process, interaction relationship tends be neutral. We should enhance protection pay attention management. Results revealed Carex lanceolata Boott Lespedeza bicolor Turcz coexisted easily other for mutual benefit, which could help build artificial forestland native function.
