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 mid-storey 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 Tropical Rainforest 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（LTERN Desert Uplands Plot Network Bird Count Data）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。本数据集属于覆盖2004至2013年的大型数据集的一部分。澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）的永久性样地坐落于热带铁木林（Tropical Ironbark Woodlands）中，分布在约50km×50km范围内的4个租赁牧牛牧场内。这些样地对应三种植被管理方案，分别为：1）皆伐（移除所有乔木与灌木）；2）疏伐（移除地表及林中层植被）；3）未受干扰的原生林（未进行过大规模疏伐或皆伐）。在每个1公顷样地内，研究人员会在4天周期内开展8次5分钟日间鸟类计数。每个样地每日完成2次计数：一次为日出后3小时内的晨间计数，另一次为晨间计数结束至少3小时后至日落前的时段计数。沙漠高地研究样地始建于2004年，并分别于2005、2006、2008及2013年进行了回访调查。作为热带雨林样地网络（Tropical Rainforest Plot Network）完整计划一部分所采集的相关数据集包的概要信息，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
