Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA18, 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 TIMA18. 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 2014. 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 (2015): Desert Uplands Plot Network, Bird Count Data and Notes, Northern Queensland, Australia, 2014.

Long Term Ecological Research Network. http://www.ltern.org.au/knb/metacat/ltern2.167.18/html 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收录了澳大利亚昆士兰州北部50个永久1公顷样地中1个样地的鸟类区系数据。本数据集发布特指在TIMA18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）的永久样地坐落于热带铁木林，分布在面积约50km×50km范围内的4处租赁畜牧牧场中。这些样地涵盖3种植被管理策略，分别为：1）皆伐清理（清除所有乔木与灌木）；2）疏伐改造（移除地表及中层植被）；3）未受干扰的原生铁木林（未开展过大规模疏伐或清理作业）。
在每个1公顷样地中，研究人员会在为期4天的调查周期内开展8次5分钟时长的日间鸟类计数。每个样地每日完成2次计数：一次为日出后3小时内的清晨时段计数，另一次需间隔至少3小时且于日落前完成。
本数据集隶属于采集周期涵盖2004年至2014年的更大规模数据集。需注意，此前的研究曾在60个永久1公顷样地中开展，完整数据集可通过以下组合数据包获取：Metcalfe, D; Vanderduys, E (2015): Desert Uplands Plot Network, Bird Count Data and Notes, Northern Queensland, Australia, 2014. Long Term Ecological Research Network. http://www.ltern.org.au/knb/metacat/ltern2.321.2/html.

沙漠高地研究样地于2004年始建，并分别于2005年、2006年、2008年、2013年及2014年开展回访调查。
