Desert Uplands Plot Network: Bird Count Data and Notes for Plot WOUR18, 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 WOUR18.

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个永久性1公顷样地中的1个样地的鸟类区系数据。本数据集发布的内容特指在WOUR18号样地开展的观测记录。

澳大利亚联邦科学与工业研究组织（CSIRO）的永久性样地设于热带铁木林（Tropical Ironbark Woodlands），分布于总面积约50km×50km范围内的4个租赁牧场上。这些样地涵盖3种植被管理策略，分别为：1）皆伐：移除所有乔木与灌木；2）疏伐：移除地表及中层植被；3）原生未干扰林地：未开展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次为期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小时内的晨间时段，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年大型综合数据集的一部分。需说明的是，此前的研究曾在60个永久性1公顷样地中开展，且本数据集可作为复合数据包获取：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

沙漠高地研究样地始建于2004年，并分别于2005、2006、2008及2013年进行了回访调查。关于沙漠高地样地网络完整项目所收集的相关数据包概要，可通过以下链接获取：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplandsmdup_bird_survey_data_2013
