Gibraltar Range National Park Vegetation 2002 VIS_ID 4731

Gibraltar Range and southern Washpool National Parks vegetation mapping was undertaken by Paul Sheringham and Dr John T. Hunter in 2002 by contract for the NPWS Northern Tableland Region. The study area includes Gibraltar Range National Park and the southern section of the Washpool National Park on the north coast and northern tablelands in north eastern New South Wales. The park is located on the Great Diving Range approximately 90 km east of Grafton and about 65 km east Glen Innes. The Gibraltar range straddles the northern tablelands and north coast botanical subdivisions.\r\n\r\nThe vegetation of Gibraltar Range and southern Washpool National Parks is described and mapped (scale 1:25 000). Twelve communities are defined based on PATN analysis, a thirteen is defined based on previous investigations, ten broad community associations are mapped. These ten mapping communities were mapped based on ground truthing, air photo interpretation and landform. Two communities are considered vulnerable and three rare. Most communities are of open forest structure, although sedgelands, heaths, woodlands, mallee scrubs, tall open forests and closed forests also occur. Many of the communities show considerable variation and intergrade along common boundaries.\r\n\r\nVIS_ID 4731

直布罗陀山脉国家公园与沃什布尔国家公园南部区域的植被制图项目，由保罗·谢林汉姆与约翰·T·亨特博士于2002年受NPWS北部台地区域委托承接。研究区域涵盖新南威尔士州东北部北海岸与北部台地区域内的直布罗陀山脉国家公园，以及沃什布尔国家公园南部片区。该园区坐落于大分水岭（Great Dividing Range）之上，距格拉夫顿以东约90公里，距格伦因尼斯以东约65公里。直布罗陀山脉横跨北部台地与北海岸植物分区。

本研究对直布罗陀山脉国家公园与沃什布尔国家公园南部区域的植被开展了系统性描述与制图工作，制图比例尺为1:25000。基于PATN分析（PATN analysis）共划定12个植被群落，另有1个群落依据既往研究得以界定，最终共制图10个广义群落关联单元。上述10个制图群落均通过地面实测验证、航空相片解译与地形地貌分析完成成图。其中2个群落被列为易危类群，3个群落被列为稀有类群。多数群落呈现疏林结构，不过区域内亦分布有莎草沼泽、石楠灌丛、疏林、马利灌丛、高大疏林与密闭林。多数群落在共同边界处存在显著变异与渐变过渡现象。
