| 2021 年, 通过红外相机在广东蕉岭长潭省级自然保护区内首次记录到极度濒危的国家重点保
护动物中华穿山甲 Manis pentadactyla 活动。 为有效保护该珍稀物种, 保护区于 2022—2023 年通过野外样
线调查、 红外相机监测、 环境因子采集等方法对中华穿山甲的种群数量与分布、 栖息地面积与分布、 受
威胁因素等进行监测。 共记录到中华穿山甲活体 6 只次, 洞穴 38 个, 估计种群数量为 (35. 97±56. 28)
只, 估计该物种核心分布面积为 2. 69 km

, 位于保护区南侧, 栖息地通常位于 200 ~ 300 m 海拔段、 上坡
位、 陡坡、 半阴半阳坡, 及针阔混交林生境。 保护区中华穿山甲是具有繁殖力的极小种群, 易受非法捕
猎与栖息地破坏影响, 需进一步采取措施进行严格保护。 |

| Abstract: |
| In 2021, infrared camera monitoring in Guangdong Jiaoling Changtan Provincial Nature Reserve
captured documented activity of the critically endangered Manis pentadactyla, a National Class I Protected Species. To effectively protect this rare species, the reserve monitored the population size and distribution, habitat
area and distribution, and key threatening factors of the local M. pentadactyla through line transect survey, infrared camera monitoring, and environmental factor collection from 2022 to 2023. A total of 6 live individuals
and 38 burrows were recorded. The estimated population size was (35. 97±56. 28). The core distribution area
of the species was estimated to be 2. 69 km
2
, which was located on the south side of the reserve. The habitat is
usually located at an altitude of 200 - 300 m, upland, steep slope, semi -shade and semi -sunny slope, and theropencedrymion habitat. The M. pentadactyla in the reserve is an extremely small population with fecundity,
which is vulnerable to illegal hunting and habitat destruction, and requires immediate and strict protection measures. |
