Jervis Bay Booderee National Park Plot Network: Bird Count Survey Data, Booderee National Park, Jervis Bay Territory, 2013

This bird count data package comprises repeated time-controlled point interval counts conducted annually along a permanent 100 metre-long transect. The abundance of species observed or heard is recorded, and counts are not undertaken in poor weather (rain, fog or high wind). Two five-minute counts are conducted at each site, one at the 20 m mark and the other at 80 m mark of the transect. All birds seen or heard are recorded and assigned to different distance classes. Each site is surveyed on a different day by a different observer to reduce day effects on detection and reduce problems with observer differences. Surveys are completed in late September each year. Bird count surveys commenced in 2002 and have been conducted since on an annual basis. The Jervis Bay Booderee National Park Plot Network was established in 2002 in Booderee National Park in the Jervis Bay Territory, South-eastern Australia. The study location is a floristically diverse area in which fire history has been well-documented over several decades. The plot network’s objectives involve quantifying the inter-relationships between natural disturbance and/or management intervention (including weed and feral animal control and prescribed burning) and the reciprocal changes in vegetation condition and biodiversity response. The Jervis Bay Booderee National Park Plot Network study forms part of the collection of data packages by this plot network. A synopsis of related data packages which have been collected as part of the Jervis Bay Booderee National Park Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/jervis-bay-booderee-national-park.

本鸟类计数数据集包含沿固定100米样线开展的、经时间管控的定点间隔重复调查数据。调查会记录观测或听闻到的鸟类物种丰富度，且恶劣天气（降雨、大雾或强风）时不开展计数工作。每个样点开展两次时长5分钟的计数：一次设于样线20米标记处，另一次设于80米标记处。所有观测或听闻到的鸟类均会被记录，并按不同距离区间进行分类。为降低日期效应对鸟类探测的影响，以及规避观测者个体差异带来的问题，每个样点会由不同观测者于不同日期开展调查。调查于每年9月下旬完成。鸟类计数调查始于2002年，此后每年持续开展。杰维斯湾布德里国家公园样地网络（Jervis Bay Booderee National Park Plot Network）于2002年在澳大利亚东南部杰维斯湾领地的布德里国家公园内设立。该研究区域为植物区系多样性丰富的区域，数十年来的火灾历史均有完整记录。该样地网络的研究目标为量化自然干扰与/或管理干预（包括杂草防控、外来动物防治以及计划火烧）之间的相互关系，以及植被状况与生物多样性响应的双向变化。本次鸟类计数调查是杰维斯湾布德里国家公园样地网络所收集数据集的组成部分。杰维斯湾布德里国家公园样地网络完整项目中所收集的相关数据集概览，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/jervis-bay-booderee-national-park。
