Spermatophyta and invasive plants in Wanda Mountains, Heilongjiang Province, China

Study Extent

Wanda Mountains is located in the southeast of Heilongjiang Province, China, and the central vein runs from the northeast to the southwest. Wanda Mountains is one of the significant mountains of eastern Heilongjiang Province. The data presented in this checklist come from specimen records, field surveys, and local floras. We do not find any records in GBIF but 1767 records in NSII.

Sampling

From 2018 to 2020, we set 25 line transect and 420 quadrats, 60 for arborous plants (25 m × 25 m), 120 for shrub plants (5 m × 5 m), and 240 for herbaceous plants (1 m × 1 m) in Wanda Mountains while undertaking the project “The risk of invasive plants in Heilongjiang Province.” All species, both in quadrats and line transect, have been recorded.

Method steps

1. Local floras we used include "Flora Heilongjiangensis" (Zhou 2003), "Ligneous Flora of Heilongjiang" (Zhou 1986), "Flora Plantarum Medicinalium Chinae Boreali-Orientalis" (Liou 1959), "Flora Plantarum Herbacearum Chinae Boreali–Orientalis" (Liou 2004), "Atlas of Northeast Plant Distribution" (Cao et al. 2018). We referred "The Survey Reports on Chinese Alien Invasive Plants" to discriminate invasive alien plants (Ma 2014). We determined the scientific name in original data by reference to the accept name in the TPL database (The Plant List 2013), and the distribution area information referred to the Species 2000 database (Species 2000 China The Biodiversity Committee of Chinese Academy of Sciences 2020). At last, we used Christenhusz system (Christenhusz et al. 2010) for gymnosperms and APGIV system (The Angiosperm Phylogeny Group 2016) for angiosperms, in order to unify the classification system.

Wanda Mountains, one of the main mountainous regions in the east of Heilongjiang Province, is facing Russia across the Ussuri River (latitude 44°51′13″ to 47°10′30″ North, longitude 129°30′20″ to 134°10′10″ East), with a total area of 4486,000 hm2
