Biodiversity is the basis of ecosystem services, and the two are closely related. Earlier studies have assessed their relationship at the regional or watershed scale.
Researchers from Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences and their collaborators have pioneered a pixel-scale matching degree analysis framework to quantify endangered plant diversity andon Aug. 16.
By using the maximum entropy and Integrated Valuation of Ecosystem Services and Trade-offs models, the researchers created a spatial matching degree index of high-resolution with 30m × 30m pixel size. Using the framework, they modeled and depicted the spatial matching degree index of endangered plant diversity and ecosystem services in Xishuangbanna. The matching degree was classified into four types: low–low, low–high, high–low, and high–high.
They found that there was a mismatch relationship between the endangered plant diversity and ecosystem services in more than 70% of areas. Under the influence of altitude and/land cover type, the matching degree of endangered plant diversity and ecosystem services showed obvious spatial heterogeneity.
In low-altitude areas in the south of Xishuangbanna, endangered plant diversity and ecosystem services mainly showed mismatch, while high-altitude areas in the west had a better match. In

Biodiversity protects against invasions of non-native tree species, study findsFor centuries, human activity has intentionally or unintentionally driven the spread of plant species to areas far outside their native habitat. On average, about 10% of non-native species worldwide become invasive, often causing large ecological and economic consequences for affected regions.
