Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA02, 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 TIMA02.

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.

本数据集为沙漠高地样地网络（Desert Uplands Plot Network）鸟类计数数据集，涵盖澳大利亚昆士兰州北部50个永久1公顷样地中TIMA02样地的鸟类区系观测数据。本数据出版物特指TIMA02样地的观测记录。

该CSIRO永久样地分布于热带铁木林（Tropical Ironbark Woodlands）中，覆盖4处租赁牧场地，样地群整体坐落于约50km×50km的区域内。样地对应3种植被管理策略，分别为：1）皆伐：移除所有乔木与灌木；2）疏伐：移除地表及中层植被；3）原生未干扰林地：未开展过显著疏伐或皆伐作业。在每个1公顷样地内，于为期4天的周期中开展8次时长5分钟的日间鸟类计数：每个样地每日完成2次计数，一次为日出后3小时内的晨间调查，另一次为晨间调查结束至少3小时后至日落前的时段调查。

本数据集隶属于覆盖2004至2013年的更大规模数据集。需说明，此前的研究曾在60个永久1公顷样地中开展，该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，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，可访问以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
