Desert Uplands Plot Network: Bird Count Data and Notes for Plot WOUR17, 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 WOUR17.

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 midstorey 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:

The Desert Uplands research plots commenced in 2004, and have been revisited in 2005, 2006, 2008 and 2013.

沙漠高地样地网络鸟类计数数据集包含澳大利亚昆士兰州北部50个永久1公顷样地中的1个样地的鸟类区系数据。本次数据发布特指在WOUR17号样地开展的观测记录。

CSIRO（澳大利亚联邦科学与工业研究组织）设立的永久样地位于热带铁木桉林地中，覆盖约50km×50km范围内的4个租赁牧牛牧场。该样地网络涵盖3种植被管理策略，分别为：1）皆伐（清除所有乔木与灌木）；2）疏伐（清除地表及中层植被）；3）未受干扰的原生林地（未开展过大规模疏伐或皆伐作业）。在每个1公顷样地内，研究人员于4天周期内开展8次5分钟日间鸟类计数。每个样地每日完成2次计数：一次于日出后3小时内的晨间开展，另一次则于晨间计数结束至少3小时后、日落前完成。

本数据集为2004至2013年大型观测数据集的一部分。需注意，过往研究曾在60个永久1公顷样地中开展，本次数据可作为组合数据包获取：

沙漠高地研究样地始建于2004年，并分别于2005、2006、2008及2013年开展复查。
