In China, the invasion of Spartina alterniflora is an important driver for decrease mangrove area and ecological service functions related to this habitat. past few decades, S. clearing restoration projects have mainly focused on areas where it already changed but ignored potential distribution areas. This study suggested that implementation protection prior with threat could greatly improve efficiency save costs. Thus, using Maximum Entropy Modeling (MaxEnt), we estimated spatial both mangroves in considering current data, topographical, sediments, sea surface temperature bioclimatic variables. What’s more, identified calculated distributed each province. We aimed explore (i) key factors determining along coastline (ii) hotspots their competitive occurrence, including degradation areas, order support conservation. The model showed distance topography play roles alterniflora, while were more sensitive range annual temperature. Our results furthermore confirm has a wider (~10,585 km2) than (~9124 at China; predict provinces Zhangzhou, Quanzhou, Zhanjiang, Beihai Wenzhou as competition between alterniflora. propose priority should be given or plants those which are co-suitable these management measures conducted hinder invasions clear existing plants, firstly. provides guidance native species by preventing biological invasion.
