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收录了澳大利亚昆士兰州北部50个永久性1公顷样地（2008年前为60个）的鸟类区系数据。该数据集隶属于覆盖2004年至2013年的更大规模数据集集合。由联邦科学与工业研究组织（CSIRO）设立的永久性样地分布于热带铁木林（Tropical Ironbark Woodlands）中，横跨4处租赁牧牛场地，分布范围约为50千米×50千米。该批样地对应三种植被管理策略，分别为：1）皆伐（清除所有乔木与灌木）；2）疏伐（移除地表及中层植被）；3）未受干扰的原生林（未开展过大规模疏伐或皆伐作业）。在每个1公顷样地内，研究人员会在4天周期内开展8次为期5分钟的日间鸟类计数：每日完成2次计数，分别为日出后3小时内的晨间计数，以及晨间计数结束至少3小时后至日落前的午后计数。该沙漠高地研究样地于2004年设立，并分别在2005、2006、2008及2013年进行了重访调查。作为沙漠高地样地网络完整研究计划的一部分，已收集的相关数据集包概要可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
