Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA08, 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 TIMA08. 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.

本数据集为澳大利亚昆士兰州北部50个永久1公顷样地中其中1个样地的鸟类区系数据，隶属于荒漠高地样地网络鸟类计数数据集。本次发布的数据特指TIMA08样地的野外观测记录。
澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）设立的永久样地坐落于热带铁木林中，样地分布于一片约50km×50km的区域内，横跨4个租赁牧牛牧场。该样地共涵盖3种植被管理策略，分别为：1）皆伐清理：移除所有乔木与灌木；2）疏伐：移除地表植被与中层植被；3）原生未干扰林：未进行过大规模疏伐或皆伐的原生林地。
在每个1公顷样地中，研究人员会在为期4天的周期内开展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：一次于日出后3小时内开展，另一次则于当日日出3小时后至日落前完成。
本数据集是一套涵盖2004年至2013年的大型数据集的一部分。需说明的是，此前的研究曾在60个永久1公顷样地中开展，本次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荒漠高地样地网络鸟类计数数据及记录，2013. 长期生态研究网络（Long Term Ecological Research Network, LTERN）。访问链接：http://www.ltern.org.au/knb/metacat/ltern2.145.23/html
荒漠高地研究样地始建于2004年，并分别于2005年、2006年、2008年及2013年进行了回访调查。
