Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA15, 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 TIMA15. 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包含澳大利亚昆士兰州北部50处永久1公顷样地中的1处样地的鸟类区系数据。本数据出版物特指针对TIMA15样地开展的观测记录。
由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，覆盖约50km×50km范围内的4处租赁牧牛场。该批样地对应三类植被管理策略，分别为：1）清伐（移除所有乔木与灌木）；2）疏伐（移除地表及中层植被）；3）未受干扰的原生林地（未开展显著疏伐或清伐作业）。
在每处1公顷样地内，于4天周期内开展8次时长5分钟的日间鸟类计数。每日在每个样地完成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、日落前的时段计数。
本数据集隶属于2004年至2013年间采集的更大规模数据集。需说明的是，此前的研究曾在60处永久1公顷样地开展观测，完整数据集可通过以下组合数据包获取：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
沙漠高地研究样地于2004年设立，并分别于2005、2006、2008及2013年进行回访监测。
