Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA16, 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 TIMA16.

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（Desert Uplands Plot Network Bird Count Data）收录澳大利亚昆士兰州北部50个永久性1公顷样地的鸟类区系数据，本数据出版物特指TIM16样地的观测数据。

澳大利亚联邦科学与工业研究组织（CSIRO）设立的永久性样地位于热带铁木林（Tropical Ironbark Woodlands）中，分布在约50km×50km范围内的4个租赁牧牛牧场。该样地覆盖3种植被管理策略，具体为：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，于4天的调查周期内开展8次5分钟日间鸟类计数：每日完成2次计数，一次在日出后3小时内的晨间时段，另一次则间隔至少3小时后至日落前完成。

本数据集隶属于2004至2013年的更大规模数据集。需说明的是，此前的研究曾在60个永久性1公顷样地中开展，相关数据可通过组合数据包获取：

沙漠高地研究样地于2004年设立，分别于2005、2006、2008及2013年进行回访调查。关于沙漠高地样地网络完整项目所采集的相关数据包概要，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
