Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA17, 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 TIMA17.

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:

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个永久1公顷样地中1个样地的鸟类区系数据，本数据出版物特指在TIMA17样地开展的观测记录。

澳大利亚联邦科学与工业研究组织（CSIRO）设立的永久样地位于热带铁木林（Tropical Ironbark Woodlands）中，分布于总面积约50km×50km的4处租赁牧牛场地块内。该样地涵盖三种植被管理策略，分别为：1）皆伐（清除所有乔木与灌木）；2）疏伐（清除地表及中层植被）；3）未受干扰的原生林（未开展显著疏伐或皆伐的区域）。在每个1公顷样地内，研究人员于4天周期内开展8次日间鸟类计数，每次计数时长为5分钟。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、日落前的时段计数。

本数据集属于覆盖2004至2013年的更大规模数据集的一部分。需注意，过往研究曾在60个永久1公顷样地中开展，本数据集可作为组合数据包获取，引用信息如下：

沙漠高地研究样地始建于2004年，并分别于2005、2006、2008及2013年进行了回访监测。有关沙漠高地样地网络完整项目所收集的相关数据包的概要信息，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
