Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA11, 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 TIMA11. 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.

澳大利亚昆士兰州北部沙漠高地样地网络鸟类计数数据，包含当地50个永久1公顷样地中1个样地的鸟类区系数据。本数据出版物特指TIMA11号样地的观测记录。澳大利亚联邦科学与工业研究组织（CSIRO）设立的永久样地坐落于热带铁木桉林地内，分布于约50km×50km范围内的4个租赁牧牛场地中。这些样地涵盖3类植被管理策略，分别为：1）清理样地（移除所有乔木与灌木）；2）疏伐样地（移除地表与中层植被）；3）未受干扰原生林地（未开展过大规模疏伐或清理的原生林地）。在每个1公顷样地内，研究人员于4天周期内开展8次时长5分钟的日间鸟类计数。每个样地每日完成2次计数：一次在日出后3小时内的清晨时段，另一次则在该时段结束至少3小时后、日落前完成。本数据集属于2004至2013年期间收集的更大规模数据集的一部分。需说明的是，此前的研究曾在60个永久1公顷样地中开展，本数据集可作为整合数据包获取：Metcalfe D、Vanderduys E（2014）：《澳大利亚昆士兰州北部沙漠高地样地网络：鸟类计数数据与记录》，2013年，长期生态研究网络（Long Term Ecological Research Network, LTERN）。访问网址：http://www.ltern.org.au/knb/metacat/ltern2.145/html。沙漠高地研究样地于2004年设立，分别于2005、2006、2008及2013年进行了回访调查。沙漠高地样地网络完整项目所收集的相关数据包概要，可通过以下网址获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
