Desert Uplands Plot Network: Bird Count Data and Notes for Plot PENR07, 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 PENR07.

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.

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处永久性1公顷样地的鸟类区系数据，本数据集出版物特指针对PENR07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）的永久性样地设于热带铁木林（Tropical Ironbark Woodlands）中，分布于面积约50km×50km范围内的4处租赁牧场地内。该批样地涵盖3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（移除地表及中层植被）；3）原生未干扰林地（未开展显著疏伐或皆伐作业）。在每处1公顷样地中，将在4天周期内开展8次为期5分钟的日间鸟类计数：每日完成2次计数，分别为日出后3小时内的晨间计数，以及该时段结束后至少3小时且于日落前进行的单次计数。

本数据集隶属于2004至2014年的更大规模数据集。需注意，此前的研究曾在60处永久性1公顷样地开展观测，完整复合数据集可通过以下数据包获取：

沙漠高地研究样地始建于2004年，并分别于2005、2006、2008、2013及2014年开展复查。沙漠高地样地网络完整项目所收集的相关数据包概览，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
