摘要: 野化放归是维持濒危野生动物种群长期续存的重要手段,而对于圈养动物放归自然来说,如何较快地适应复杂的野外环境,是能够成功放归的重要保障。因此,深入研究动物放归后的栖息地偏好、活动模式及环境因子利用等特征,有助于掌握其环境适应的过程。本研究对大熊猫 (Ailuropoda melanoleuca) 进入自然环境后 6 个月内的栖息地偏好,12 个月内的家域、日移动距离和环境因子利用等特征进行了分析,以了解其野外适应过程。研究发现大熊猫个体很好地适应了野外环境,家域稳定后其栖息地偏好与野生大熊猫相似,偏好栖息地重合比例最高达 66%;第 12 个月活动家域面积为 4.5 km2;平均日移动距离为 (293.2 ± 420.2) m;月平均利用海拔为 (2 721.3 ± 66.9) m;活动区域平均坡度中位数小于 20.0°;主要活动于阳坡及半阳坡区域。大熊猫适应过程分为探索期 (1 ~ 31 d)、初始稳定期 (32 ~ 61 d)、游荡期 (62 ~ 91 d) 和稳定期 (92 d 以后) 4 个阶段。本研究还发现对于放归成年雌性圈养个体,延长野化训练周期,可能会在一定程度上让其在较短的时间内进入稳定期,从而提升放归成功率。本研究结果可为进一步优化圈养大熊猫野化培训和监测等方案提供依据。

Abstract: Animal rewilding is an important means to maintain the long-term survival of endangered wildlife populations. For captive animals, how to quickly adapt to the complex wild environment is an important guarantee for successful survival. Therefore, knowing habitat preference, activity patterns, and utilization of environmental factors is helpful to clarify the process of ecological adaptation of reintroduced animals. In this study, we focused on the preferred habitat within 6 months, home range size, daily movement distance, and use of environmental factors within 12 months of a reintroduced giant panda (Ailuropoda melanoleuca). After 6 months later, the reintroduced giant panda showed the similar habitat preference as wild giant pandas in the same area (the coincidence ratio up to 66%), with a utilization (2 721. 3 ± 66. 9) m altitude in the end of one year. Also, the reintroduced giant panda exhibited a 4. 5 km2 home range, moved (293. 2 ± 420. 2) m average distance daily, used a 20. 0° median average slope of the active area in sunny slope and semisunny slope areas. Based on the results, we divide the adaptation process in 4 stages: exploratory period (1 - 31 d), initial stable period (32 - 61 d), wandering period (62 - 91 d), and stable period (after 92 d), after which the reintroduced individual was well adapted to the wild environment. Our study indicates that releasing adult captive females and extending the rewilding training period may benefit reintroduced giant pandas to enter a stable stage in a relatively short period, thereby improving the success rate of reintroduction. The results of this study can provide a basis for further optimization of captive giant panda rewilding training and monitoring programs.
