Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA15, 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 TIMA15. 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.

澳大利亚昆士兰州北部的沙漠高地样地网络鸟类计数数据集，涵盖该区域50个永久性1公顷样地中1个样地的鸟类区系数据。本次发布的数据特指TIMA15样地的观测记录。
澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）设立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个租赁肉牛牧场内。
这些样地对应三类植被管理策略，分别为：1）皆伐清理（移除所有乔木与灌木）；2）疏伐（移除地表与中层植被）；3）原生未干扰林（未开展过大规模疏伐或皆伐作业的原生林地）。
在每个1公顷样地内，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：一次为日出后3小时内的清晨观测，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2004至2013年采集的更大规模数据集集合。
需注意，此前的研究曾在60个永久性1公顷样地中开展，本数据可作为组合数据包获取：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，长期生态研究网络（Long Term Ecological Research Network）。访问链接：http://www.ltern.org.au/knb/metacat/ltern2.145.23/html
沙漠高地研究样地于2004年设立，并分别于2005、2006、2008及2013年进行了回访监测。
