Desert Uplands Plot Network: Bird Count Data and Notes for Plot TIMA12, 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 TIMA12.

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（Desert Uplands Plot Network Bird Count Data）涵盖澳大利亚昆士兰州北部50个永久性1公顷样地中1个样地的鸟类区系数据，本数据出版物特指在TIMA12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）设置的永久性样地分布于热带铁木林（Tropical Ironbark Woodlands）中，覆盖4个租赁牧牛场地，样地分布区域总面积约为50km×50km。这些样地对应3种植被管理策略，分别为：1）皆伐处理：清除所有乔木与灌木；2）疏伐处理：清除地表植被与中层植被；3）原生林原状处理：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，另一次则在晨间计数结束至少3小时后至日落前的时段内开展。

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，该综合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年、2006年、2008年及2013年进行了回访调查。
