Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA01, Northern Queensland, Australia, 2013

The Desert Uplands Plot Network Bird Count Data contains bird fauna data for 1 of 50 permanent 1 hectare plots in Northern Queensland, Australia. This data publication refers specifically to observations made at Plot TIMA01. 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. This is part of a much larger dataset that spans from 2004 to 2013. Note that previous studies were undertaken at 60 permanent 1 hectare plots and that this data is accessible as a composite data package: Metcalfe, D; Vanderduys, E (2014): Desert Uplands Plot Network: Bird Count Data and Notes, Northern Queensland, Australia, 2013. Long Term Ecological Research Network. http://www.ltern.org.au/knb/metacat/ltern2.145.23/html The Desert Uplands research plots commenced in 2004, and have been revisited in 2005, 2006, 2008 and 2013.

《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块永久性1公顷样地中1块的鸟类区系数据，本数据出版物特指TIMA01号样地的观测记录。澳大利亚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，覆盖约50km×50km区域内的4处租赁牧牛牧场。这些样地涵盖3种植被管理策略，分别为：1）皆伐（清除全部乔木与灌木）；2）疏伐（清除地表与中层植被）；3）未受干扰的原生林地（未开展过大规模疏伐或皆伐作业）。在每块1公顷样地内，研究人员于4天周期内开展8次时长5分钟的日间鸟类计数。每块样地每日完成2次计数：一次在日出后3小时内的晨间时段，另一次则需在晨间计数结束至少3小时后、日落前完成。本数据集为2004至2013年大型综合数据集的组成部分。需说明的是，此前的研究曾覆盖60块永久性1公顷样地，本数据可通过以下复合数据包获取：Metcalfe, D; Vanderduys, E (2014): Desert Uplands Plot Network: Bird Count Data and Notes, Northern Queensland, Australia, 2013. 长期生态研究网络（Long Term Ecological Research Network）。数据链接：http://www.ltern.org.au/knb/metacat/ltern2.145.23/html。沙漠高地研究样地始建于2004年，并分别于2005、2006、2008及2013年开展回访调查。沙漠高地样地网络完整项目所收集的相关数据包概要，可通过以下链接查阅：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
