Study Extent

From 2018 to 2020, we surveyed the forest-covered region of the Wanda Mountains, with an area over 12,000 km2, including 12 administrative districts.

Sampling

The data presented in this checklist come from specimen records, local floras, and field surveys. We did not find any records in GBIF but 1767 records in NSII. In order to fully understand the plant species diversity in Wanda Mountains, transect lines and quadrats were set up in this area from 2018 to 2020. During the setting of transect and quadrat, we carefully considered the differences of species distribution in different altitudes, precipitation, vegetation, habitats and human disturbance areas, and finally determined 25 transects (about 250km in total) and 420 quadrats to cover all the above areas. Among the 420 quadrats, there are 60 for arborous plants (25m × 25m), 120 for shrub plants (5m × 5m), and 240 for herbaceous plants (1m × 1m). All species, both in quadrats and transect lines, have been recorded.

Method steps

1. 1. Obtain the preliminary checklist through published materials, specimen records as well as field survey; 2. Correct the taxonomic status and scientific names to get the final checklist; 3. Sort and identify the data based on published documents such as local floras and reports on invasive alien plants as well as specimen records.

This data paper presents the first checklist of spermatophytes and invasive alien plants in the Wanda Mountains, comprising a total of 704 species and infraspecific taxa. Among these, there are 656 native plants belonging to 329 genera and 94 families, and 48 invasive alien plants belonging to 39 genera and 20 families.
