Landscapes for the conservation of the Giant Ibis in Cambodia

朱鹭是一种极度濒危的鸟类，目前仅限于分布在柬埔寨北部大草原的少数种群。通过一项社区保护计划，柬埔寨野生动物保护协会(WCS)保护了大约20%的筑巢种群，大多数鸟巢每年都能成功地繁殖幼崽，但经过十年的这样的工作，种群还没有恢复的迹象。朱鹭占据的稀树草原经历了景观规模的变化，大型食草动物的消失以各种方式改变了景观，这可能会影响朱鹭的招募，但年轻的朱鹭对景观的利用鲜为人知。WCS打算实施景观管理活动，以增加朱鹭的数量，该项目将使用GPS跟踪技术来评估这些工作的成功，并协助制定新的保护计划。目的：(1)通过GPS标签识别朱鹭幼年所使用的景观特征。(2)评估旨在模拟水坑和整个景观中草食动物活动的干预措施的成功(3)检验大型食草动物的丧失正在阻止朱鹭恢复的假设(4)为大型朱鹭制定最新的保护行动计划

The Giant Ibis is a critically endangered species of bird, now restricted to a small population scattered across the savannahs of northern Cambodia. Through a community conservation programme, the Wildlife Conservation Society (WCS) Cambodia protect around 20% of the nesting population, most nests successfully raising young each year but after a decade of such work, there is no sign of a population recovery yet. The savannahs occupied by the ibis have seen landscape-scale changes with loss of large herbivores altering the landscape in a variety of ways that may affect ibis recruitment, but the use of the landscape by young ibis is poorly known. WCS intend to implement landscape management activities to boost ibis populations and this project will use GPS tracking technology to assess the success of these works and assist in developing new conservation plans.OBJECTIVES:(1) To identify the landscape features used by young ibis through GPS tagging.(2) To evaluate the success of interventions designed to simulate herbivore activity at waterholes and across the landscape(3) To test the hypothesis that loss of large herbivores is preventing ibis recovery(4) To develop an updated conservation action plan for Giant Ibis
