Desert Uplands Plot Network: Bird Count Data and Notes, Northern Queensland, Australia, 2013

The LTERN Desert Uplands Plot Network Bird Count Data contains bird fauna data for 50 permanent 1 hectare plots (60 prior to 2008) in Northern Queensland, Australia. This is part of a much larger dataset that spans from 2004 to 2013. The CSIRO permanent plots are situated in Tropical Ironbark Woodlands, and extend across four leasehold cattle properties that lie within an area approximately 50km by 50km. The plots represent three vegetation management strategies, namely: 1) clearing (where all trees and shrubs are removed); 2) thinning (where ground and midstorey vegetation is removed); and 3) unmodified native woodlands where significant thinning or clearing has not occurred. Within each 1 ha site, eight five-minute diurnal bird counts are conducted over a four day period. Two counts are completed per day at each site: one count in the morning within three hours of sunrise and the other a minimum of three hours after this period and before sunset. The Desert Uplands research plots commenced in 2004, and have been revisited in 2005, 2006, 2008 and 2013. A synopsis of related data packages which have been collected as part of the Desert Uplands Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands

LTERN沙漠高地样地网络鸟类计数数据集包含澳大利亚昆士兰州北部50个永久1公顷样地（2008年前为60个）的鸟类区系数据。本数据集是2004至2013年采集的更大规模数据集的组成部分。澳大利亚联邦科学与工业研究组织（CSIRO）设立的永久样地分布于热带铁桉林地中，覆盖4处租赁肉牛牧场，区域总面积约为50千米×50千米。该批样地涵盖3种植被管理策略，分别为：1）皆伐模式（清除全部乔木与灌木）；2）疏伐模式（清除下层与中层植被）；3）未受干扰的原生林地（未开展过大规模疏伐或皆伐操作）。在每处1公顷样地中，于4天的调查周期内开展8次时长为5分钟的日间鸟类计数。每个样地每日完成2次计数：一次在日出后3小时内的晨间时段，另一次则于该时段结束至少3小时后、日落前完成。沙漠高地研究样地于2004年正式设立，分别在2005、2006、2008及2013年进行回访调查。作为沙漠高地样地网络完整研究计划一部分采集的相关数据集概述，可通过以下链接查看：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
