Riverine macroinvertebrates in a Cangshan mountain range of the Southwest China

The data show community structure at local sites. The datasheet has an abundance matrix (with sites as rows and taxa as columns). The community data were collected in the Cangshan Mountains located in a national, nature reserve in Yunnan Province, Southwest China. From November to December in 2012 (the dry season), 46 sites were surveyed along six streams on the east (21 sites) and west aspects (25 sites). At each site, macroinvertebrate samples were collected along a river reach of 50 to 100 m. Five replicates of the macroinvertebrate sample were collected from multiple habitats. For each replicate, macroinvertebrates were collected using a Surber sampler (30 × 30 cm with 500 μm mesh).
