Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA13, Northern Queensland, Australia, 2014

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 TIMA13.

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 2014. 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, 2013 and 2014.

本数据集为澳大利亚昆士兰州北部50个永久性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TIMA13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）的永久性样地坐落于热带硬桉林地中，分布于一片约50km×50km的区域内，覆盖4处租赁牧牛场。该批样地涵盖3种植被管理策略：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）未改造原生林地：未开展大规模疏伐或清伐作业的原生林地。

在每个1公顷样地中，研究人员于4天周期内开展8次为期5分钟的日间鸟类计数。每个样地每日完成2次计数：一次在日出后3小时内的晨间时段，另一次则于晨间计数结束至少3小时后、日落前进行。

本数据集为2004至2014年大型综合数据集的一部分。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，该综合数据集可通过组合数据包获取：

沙漠高地研究样地于2004年设立，并分别于2005、2006、2008、2013及2014年进行了回访调查。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
