Venus Bay Conservation Park and Brush-tailed Bettong Release and Monitoring Survey, Biological Survey of South Australia - Vegetation Survey, Biological Database of South Australia

This survey constitutes part of the Ecological Restoration of Eyre Peninsula program and Ark on Eyre. Monitoring was conducted each spring from 1992 to 1999, although not all traplines were opened during the 1997 and 98 seasons. Pest foxes, cats and rabbits were eradicated by traps, baits and shooting ready for re-introduction of Bettongs. The response of integrated vermin control of rabbits foxes and cats was monitored. The first trial re-introduction of six male Brush-tailed Bettongs into Venus Bay Conservation Park (VBCP) was conducted in April 1994. The bettongs were radio-collared and tracked over several months to monitor their behaviour and survival. Following the success of the release, four subsequent releases occurred between September 1994 and January 1995. A total of 61 animals (22 males and 39 females) were released during this time, taking the total number of released individuals to 67. From December 2004 to October 2005 Spotlight surveys along transects were conducted every two-three months to monitor the bettong population. Vegetation photopoints were also set-up and monitored between 1992 to 1995 in the Venus Bay Conservation Park. The Venus Bay Conservation Park and Brush-tailed Bettong Release and Monitoring Survey is part of the Biological Survey of South Australia Program which is a series of systematic surveys conducted across the state between 1971 and the present with the broad aim of providing a baseline inventory of South Australia's flora and fauna biodiversity.

本调查隶属于艾尔半岛生态修复项目（Ecological Restoration of Eyre Peninsula）与“艾尔方舟”（Ark on Eyre）计划。1992年至1999年的每年春季，研究人员均开展监测工作，但1997与1998年度未启用全部诱捕样线。为开展帚尾袋鼯（Brush-tailed Bettong）的重新引入工作，研究人员通过布设诱捕装置、投放毒饵及狩猎的方式灭杀了有害狐类、家猫与野兔，并针对兔、狐、家猫的综合害兽防控措施的实施效果开展监测。1994年4月，研究人员开展首次试验性放归，将6只雄性帚尾袋鼯（Brush-tailed Bettong）放归至维纳斯湾保育公园（Venus Bay Conservation Park, VBCP）；所有放归个体均佩戴无线电项圈，并在后续数月内接受追踪监测，以掌握其行为模式与存活状况。此次放归取得成功后，研究人员于1994年9月至1995年1月期间又开展了4次后续放归，在此期间累计放归61只个体（其中雄性22只、雌性39只），使累计放归个体总数达到67只。2004年12月至2005年10月期间，研究人员每2至3个月开展一次沿样线的夜间灯光调查，以监测帚尾袋鼯的种群动态。1992年至1995年间，研究人员还在维纳斯湾保育公园内设立了植被摄影监测点并开展长期监测。本次“维纳斯湾保育公园与帚尾袋鼯放归及监测调查”隶属于南澳生物调查计划（Biological Survey of South Australia Program），该计划自1971年起在南澳全州范围内开展系统性调查并持续至今，其总体目标是为南澳大利亚的动植物生物多样性建立基线名录。可通过以下链接获取本数据集：http://aekos.org.au/collection/sa.gov.au/bdbsa_veg/survey_71
