Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA16, 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 TIMA16. 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沙漠高地样地网络鸟类计数数据集，收录了当地50个永久性1公顷样地中1个样地的鸟类区系数据，本数据集特指TIMA16样地的观测记录。

CSIRO（澳大利亚联邦科学与工业研究组织）设立的永久性样地分布于热带铁木林（Tropical Ironbark Woodlands），横跨4个租赁牧牛场，分布范围约为50千米×50千米。该样地覆盖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：移除下层与中层植被；3）未受干扰的原生林：未进行过大规模疏伐或皆伐作业。

在每个1公顷样地中，研究人员会在4天周期内开展8次为期5分钟的日间鸟类计数。每日完成2次计数：一次在日出后3小时内的晨间时段，另一次则需间隔至少3小时，且在日落前完成。

本数据集隶属于一套跨度为2004年至2013年的大型综合数据集。需说明的是，过往研究曾在60个永久性1公顷样地中开展，本数据集可作为组合数据包获取：Metcalfe, D; Vanderduys, E (2014): Desert Uplands Plot Network: Bird Count Data and Notes, Northern Queensland, Australia, 2013. 长期生态研究网络（Long Term Ecological Research Network）。访问地址：http://www.ltern.org.au/knb/metacat/ltern2.145.23/html

沙漠高地研究样地始建于2004年，分别于2005、2006、2008及2013年进行了回访调查。
