Desert Uplands Plot Network, Bird Count Data and Notes for Plot PENR09, Northern Queensland, Australia, 2014

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 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 2014. 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 (2015): Desert Uplands Plot Network, Bird Count Data and Notes, Northern Queensland, Australia, 2014.

Long Term Ecological Research Network. http://www.ltern.org.au/knb/metacat/ltern2.167.18/html The Desert Uplands research plots commenced in 2004, and have been revisited in 2005, 2006, 2008, 2013 and 2014.

澳大利亚昆士兰州北部荒漠高地样地网络鸟类调查数据，收录该区域50个永久性1公顷样地（permanent 1 hectare plots）中1个样地的鸟类区系数据。本数据集仅对应PENR09样地的观测记录。联邦科学与工业研究组织（CSIRO）设立的永久性样地坐落于热带铁木林（Tropical Ironbark Woodlands）中，分布在约50km×50km的区域内，横跨4处租赁牧牛场。这些样地涵盖三类植被管理策略（vegetation management strategies）：1）皆伐（clearing）：清除全部乔木与灌木；2）疏伐（thinning）：移除下层及中层植被；3）原生原状林地：未实施过大规模疏伐或皆伐的原生林地。在每个1公顷样地内，研究人员会在4天周期内开展8次昼间鸟类调查（diurnal bird counts），每次时长5分钟。每个样地每日完成2次调查：一次为日出后3小时内的晨间调查，另一次需间隔晨间调查至少3小时且在日落前完成。本数据集属于2004至2014年采集的更大规模数据集的一部分。需说明，此前的研究曾在60个永久性1公顷样地中开展，本数据集可作为整合数据包获取：Metcalfe, D; Vanderduys, E (2015): 《澳大利亚昆士兰州北部荒漠高地样地网络鸟类调查数据及记录，2014》，长期生态研究网络（Long Term Ecological Research Network, LTERN）。http://www.ltern.org.au/knb/metacat/ltern2.321.2/html。该样地的空间坐标可通过以下数据包获取：Metcalfe, D; Vanderduys, E (2014): 《澳大利亚昆士兰州北部荒漠高地样地网络：样地详情——空间坐标》，长期生态研究网络（LTERN）。http://www.ltern.org.au/knb/metacat/ltern2.167.18/html。荒漠高地研究样地于2004年设立，并分别在2005、2006、2008、2013及2014年开展回访调查。热带雨林样地网络完整项目所采集的相关数据包概要，可通过以下链接查阅：http://www.ltern.org.au/index.php/ltern-plot-networks/desert-uplands
