Desert Uplands Plot Network: Bird Count Data and Notes for Plot PENR01, 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 PENR01.

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涵盖澳大利亚昆士兰州北部50个永久性1公顷样地的鸟类区系数据，本数据集特指在PENR01样地开展的观测记录。

澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）的永久性样地坐落于热带铁木林（Tropical Ironbark Woodlands）中，分布于约50km×50km范围内的4片租赁牧场地内。该批样地对应3种植被管理策略，分别为：1）清伐：移除所有乔木与灌木；2）疏伐：移除地表与中层植被；3）原生保留林：未开展大规模疏伐或清伐的原生林地。

在每个1公顷样地中，研究人员于4天周期内开展8次5分钟日间鸟类计数。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年庞大观测数据集的一部分。需说明的是，此前研究曾在60个永久性1公顷样地中开展，且该复合数据包可获取完整数据：

沙漠高地研究样地于2004年设立，并分别于2005、2006、2008、2013及2014年开展回访调查。沙漠高地样地网络完整项目所收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
