3.1 Species distribution
records
On the basis of the selection criteria in section 2.1, we finally
identified 25 rare, endangered and/or national protected species with
high simulation accuracy, belonging to 23 genera and 19 families (Table
2). We had organized the collected species distribution data and
obtained a total of 314 distribution
records of species, and further understood the distribution status of
each species in Northwest Yunnan. The result suggested that there were
at least
four
distribution records for each species, as a result, detailed
distribution records were shown in Table 2. Among them, Dipentodon
sinicus and Psammosilene tunicoides had more occurrence records,
with a total of 59 and 41, respectively. They were mainly distributed in
the vicinity of the Gaoligong Mountain National Nature Reserve and
several PNRs (i.e., Napahai, Bitahai, Haba Snow Mountain and Yulong Snow
Mountain). However, Anisodus tanguticus , Camellia
reticulata and Paris rugosa owned few distribution records, with
four for each. They were scattered in the vicinity of Gaoligong
Mountain, Baima Snow Mountain and Cangshan Erhai NNRs.

Plants List, specifically: 1) Threat level: referenced IUCN Red List
criteria, Vulnerable (VU), Endangered (EN), Critically Endangered (CR);
