Desert Uplands Plot Network: Bird Count Data and Notes for Plot PENR06, 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 PENR06.

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.

《澳大利亚昆士兰州北部荒漠高地样地网络鸟类计数数据集》收录了澳大利亚昆士兰州北部50个永久性1公顷样地中的1个样地的鸟类区系数据。本数据集出版物特指在PENR06样地开展的观测记录。

联邦科学与工业研究组织（CSIRO）的永久性样地分布于热带铁木林（Tropical Ironbark Woodlands），横跨4处租赁牧牛场地，总面积约50千米×50千米。该批样地涵盖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（清除地表及中层植被）；3）未受干扰的原生林地（未开展大规模疏伐或皆伐作业）。在每个1公顷样地内，需在4天周期内完成8次为期5分钟的日间鸟类计数。每日在每个样地开展2次计数：一次为日出后3小时内的晨间计数，另一次为晨间计数结束至少3小时后至日落前的时段计数。

本数据集隶属于覆盖2004年至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公顷样地开展相关工作，完整复合数据集可通过以下链接获取：

荒漠高地研究样地始建于2004年，并分别于2005年、2006年、2008年及2013年进行了回访调查。关于荒漠高地样地网络完整项目所收集的相关数据集概要，可通过以下链接查阅：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
