Woodland Restoration Plot Network: Composition of Revegetated Sites Compared with Natural Vegetation, Western Sydney Parklands (Western Sydney Regional Park), NSW, Australia, 2001

This data package is a derivative product consisting of a summary of the published data package Woodland Restoration Plot Network: Vegetation Structure and Composition Data, Western Sydney Parklands (Western Sydney Regional Park), NSW, Australia, collected in 2001. (http://www.ltern.org.au/knb/metacat/ltern.120/html). These data are used to produce the graph and conclusions found in figure 8.30 on page 314 of Lindenmayer et. al 2014, Biodiversity and Environmental Change: Monitoring Challenges and Directions. These data show trends in compositional similarity of revegetated sites to remnant native vegetation in the first decade since planting (1992-2001) in a woodland restoration project. The lack of convergence between revegetated areas and native woodlands in species composition suggests that there has been little colonisation of native species in the revegetated sites. These data were collected from twenty-five 0.1 hectare sites which were established in a 10-year chronosequence of plantings that was sampled in 2001. The sites were located on retired farmland that includes a mosaic of restored vegetation (native plantings) of varying ages juxtaposed with patches of remnant vegetation and untreated, abandoned pasture. All sites were originally woodland prior to agricultural development about 200 years ago. The plantings monitored by the Woodland Restoration Plot Network research plots commenced in 1992 and have been revisited every 3-4 years since 2001.

本数据包为衍生产品，由2001年采集的已发布数据集《Woodland Restoration Plot Network: Vegetation Structure and Composition Data, Western Sydney Parklands (Western Sydney Regional Park), NSW, Australia》的摘要汇编而成，数据集元数据链接为http://www.ltern.org.au/knb/metacat/ltern.120/html。上述数据用于生成Lindenmayer等人2014年出版的《生物多样性与环境变化：监测挑战与发展方向》（Biodiversity and Environmental Change: Monitoring Challenges and Directions）一书第314页图8.30中的图表及相关结论。该数据集展示了澳大利亚新南威尔士州西悉尼公园区（西悉尼区域公园）某林地修复项目中，1992-2001年（即造林后首个十年）植被修复样地与原生本土植被的群落组成相似性变化趋势。人工修复区域与原生林地在物种组成上未呈现趋同特征，表明修复样地内本土物种的定植程度极低。本数据集采集自25个0.1公顷的样地，这些样地属于10年时间序列的造林样带，于2001年完成采样工作。样地选址于退役农田区域，该区域镶嵌分布着不同林龄的本土人工修复植被（本土造林）斑块、原生植被斑块以及未受干预的废弃牧场。所有样地在约200年前的农业开发活动之前均为原生林地。由林地修复样地网络（Woodland Restoration Plot Network）监测的造林修复项目始于1992年，自2001年起每3-4年开展一次回访监测。可通过链接http://www.ltern.org.au/index.php/ltern-plot-networks/woodland-restoration 查阅作为林地修复样地网络完整项目一部分采集的相关数据包概要。
