Desert Uplands Plot Network: Bird Count Data and Notes for Plot PENR09, 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 PENR09.

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收录了澳大利亚昆士兰州北部50个永久性1公顷样地中1个样地的鸟类群落数据，本数据集仅对应PENR09样地的观测记录。

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桉林地中，分布于一片约50km×50km的区域内，横跨4处租赁牧牛牧场。这些样地对应3种植被管理策略：1）皆伐（移除全部乔木与灌木）；2）疏伐（移除地表与中层植被）；3）未受干扰的原生林地（未开展大规模疏伐或皆伐活动）。在每个1公顷样地中，研究人员会在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。

本数据集是2004至2013年大型综合数据集的一部分。需说明的是，过往研究曾在60个永久性1公顷样地中开展，该完整数据集可通过组合数据包获取：

沙漠高地研究样地于2004年设立，并分别于2005、2006、2008及2013年进行回访监测。
