广东潮安凤凰山省级自然保护区中华穿山甲种群现状与栖息地评估OA

To assess the current population status of the Chinese pangolin(Manis pentadactyla)within the Guangdong Chao'an Fenghuangshan Provincial Nature Reserve,field surveys employing standard-ized transect protocols and infrared camera trapping were conducted during 2023 to collect empirical data on burrow distribution and habitat parameters.These data were integrated with infrared camera monitoring records from the reserve dating back to 2021,enabling a comprehensive assessment of pop-ulation resources,habitat status,and threat factors.The analysis revealed:1)A total of 50 Chinese pangolin burrows were identified,with a burrow density of 5.56/km2,and population density was es-timated to range between 0.20 and 0.53 individuals/km2,corresponding to an estimated 7～19 indi-viduals.2)The spatial distribution of pangolins within the reserve was concentrated in southwest of Bianfuyan Village,predominantly within zonal evergreen broadleaf forests and mixed coniferous-broadleaf forest communities.Significant preferences were observed for gentle slopes,elevations be-tween 500～700 m,and forest stands characterized by herbaceous layer coverage of 25％-49％.3)The primary threats identified encompass habitat loss,degradation,severe fragmentation,and poac-hing.Additionally,the presence of free-ranging domestic dogs in surrounding villages escalated the risk of potential zoonotic disease transmission.
