Desert Uplands Plot Network: Bird Count Data and Notes for Plot PENR10, 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 PENR10.

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调查数据》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，本数据集特指PENR10号样地的观测结果。

澳大利亚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）中，覆盖约50km×50km范围内的4处租赁牧牛场地。该样地涵盖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（清除地表与中层植被）；3）未受干扰的原生林（未进行过大规模疏伐或皆伐）。

在每个1公顷样地内，研究人员于4天周期内开展8次为期5分钟的日间鸟类调查。每个样地每日完成2次调查：一次于日出后3小时内的清晨时段开展，另一次则于首次调查后至少3小时且日落前完成。

本数据集属于2004至2014年期间采集的更大规模数据集的一部分。需说明的是，此前的研究曾以60个永久性1公顷样地为研究对象，该完整数据集可通过组合数据包获取：

沙漠高地研究样地始建于2004年，并分别于2005、2006、2008、2013及2014年进行了回访。沙漠高地样地网络完整项目所采集的相关数据包概览可于以下网址获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
