- Abstract
The golden snub-nosed monkey (GSNM), Rhinopithecus roxellana, is an endangered species on the IUCN Red List, and the Yuhe National Nature Reserve in Gansu is one of its principal habitats. The GSNM's protection and management rely heavily on predicting its probable suitable habitat. The Maxent model was used to examine the habitat suitability of GSNM in the Yuhe Nature Reserve and surrounding areas. Infrared cameras used to monitor GSNM in 2019–2020 provided the model with data. Through analysis and screening, 23 distribution sites of GSNM and five environmental variables were included in the final model. The findings revealed that the Yuhe Nature Reserve's area of appropriate habitat for GSNM was 248.43 km2, accounting for 52.79 percent of the reserve's total area and that this was concentrated in the core zone. The Maxent model was optimized using the Kuenm package, and the resulting value reached an exceptional level of 0.948. A Jackknife test revealed that the mean diurnal range was the most important environmental factor affecting the distribution of GSNM (45.84%). Finally, the planning of the reserve was generally in line with the predictions, and the functional zoning could be altered accordingly. We advised extending the reserve southward based on the study's findings, while strengthening the supervision of marginal areas of the reserve.
