Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA10, 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 TIMA10.

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）涵盖澳大利亚昆士兰州北部50个永久1公顷样地中单一样地的鸟类区系数据，本数据集特指于TIMA10样地开展的观测记录。

联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）布设的永久样地坐落于热带铁木桉林（Tropical Ironbark Woodlands）内，分布在一片约50km×50km区域内的4处承租牧场范围内。该批样地对应3种植被管理措施：1）皆伐（移除全部树木与灌木）；2）疏伐（移除地表及中层植被）；3）原生未受干扰林地（未开展显著疏伐或皆伐作业）。在每个1公顷样地中，于为期四天的周期内开展8次5分钟日间鸟类计数：每日完成2次计数，其一为日出后三小时内的晨间计数，其二为该时段后至少三小时且日落前的午后计数。

本数据集为2004至2013年大型观测数据集的组成部分。需说明的是，此前的研究曾在60个永久1公顷样地开展，完整数据集可通过复合数据包获取：

沙漠高地研究样地始建于2004年，并分别于2005、2006、2008及2013年进行回访。关于沙漠高地样地网络完整项目所收集的相关数据集概要，可参阅：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
