Yina Nature Reserve Vegetation 2003 VIS_ID 4763

Yina Nature Reserve vegetation mapping was undertaken by Dr John T. Hunter in 2003 by contract for the NPWS Northern Tableland Region. Yina NR is located within the New England Tablelands Bioregion and the Northern Tablelands Botanical District and is approximately 10 km east of Armidale. The reserve incorporates 101 ha within the Armidale Dumaresq Shire. The reserve was formally known as Hillgrove State Forest. \r\n\r\nThe vegetation of Yina Nature Reserve is described and mapped (scale 1:25 000).\r\nFour communities are defined based on classification (Kulczynski association). These four communities were mapped based on ground truthing, air photo interpretation and landform. Two communities are Endangered and one considered as vulnerable, the fourth is considered to be poorly reserved. Most communities are of woodland and open forest structure. The communities show considerable variation and intergrade along common boundaries and in particular on intermediate soil types.\r\n\r\nVIS_ID 4763

2003年，约翰·T·亨特博士受国家公园与野生动物服务局（NPWS）北部台地区域委托，完成了伊纳自然保护区（Yina Nature Reserve）的植被制图工作。该保护区地处新英格兰台地生物区（New England Tablelands Bioregion）与北部台地植物区（Northern Tablelands Botanical District）范围内，距离阿米代尔（Armidale）以东约10公里，隶属于阿米代尔-杜马雷斯克郡（Armidale Dumaresq Shire），占地面积为101公顷，其前身为希尔格罗夫州立森林（Hillgrove State Forest）。

本数据集对伊纳自然保护区的植被进行了系统性描述与制图，制图比例尺为1:25000。研究基于库尔钦斯基关联分类法（Kulczynski association）划定了4个植被群落，其制图工作依托实地验证（ground truthing）、航空影像解译（air photo interpretation）与地形地貌特征开展。其中2个群落属于濒危等级，1个群落被列为易危等级，剩余1个群落的保护储备不足。多数群落呈现出林地与开阔林的结构特征，各群落间存在显著差异，且在群落共同边界处，尤其是过渡性土壤类型区域，存在明显的群落过渡现象。
