Desert Uplands Plot Network: Bird Count Data and Notes for Plot PENR07, 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 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 mid-storey 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: Metcalfe, D; Vanderduys, E (2014): Desert Uplands Plot Network: Bird Count Data and Notes, Northern Queensland, Australia, 2013. Long Term Ecological Research Network. http://www.ltern.org.au/knb/metacat/ltern2.145.23/html The Desert Uplands research plots commenced in 2004, and have been revisited in 2005, 2006, 2008 and 2013.

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个永久1公顷样地（permanent 1 hectare plots）中1个样地的鸟类区系数据。本次数据发布特指在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）设立的永久样地分布于热带铁木林（Tropical Ironbark Woodlands）中，覆盖约50km×50km范围内的4个租赁牧场。这些样地对应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（清除下层及中层植被）；3）未受干扰的原生林地，未进行过大规模疏伐或皆伐。
在每个1公顷样地中，于为期4天的监测周期内开展8次5分钟的日间鸟类计数。每日在每个样地完成2次计数：一次在日出后3小时内的晨间时段，另一次在该时段结束后至少3小时且日落前的时段。
本数据集隶属于2004至2013年间采集的更大规模数据集。需注意，过往研究曾在60个永久1公顷样地开展观测，该完整数据集可通过组合数据包获取：Metcalfe, D; Vanderduys, E (2014): Desert Uplands Plot Network: Bird Count Data and Notes, Northern Queensland, Australia, 2013. Long Term Ecological Research Network. http://www.ltern.org.au/knb/metacat/ltern2.145.23/html
该沙漠高地研究样地于2004年设立，分别在2005、2006、2008及2013年进行了重访监测。
