Bald Rock National Park Vegetation 1999_2006 VIS_ID 4707

Bald Rock National Park vegetation mapping was undertaken by Dr John T. Hunter in 1999 by contract for the NPWS Northern Tableland Region along with Boonoo Boonoo National Park. The mapping was revised in 2006. Bald Rock National Park is located approximately 20 km north of Tenterfield and occurs in two sections.\r\n\r\nThe vegetation of Bald Rock National Park is described and mapped (scale 1:25 000). This forms part one of the survey of lands within these two reserves with part two of the survey incorporating newly acquired lands. Ten communities are defined based on PATN analysis and one specialised community is as circumscribed by previous surveys. These eleven communities are mapped based on ground truthing, air photo interpretation and altitude. Most communities are of a Tall Open Forest structure, however Woodlands exist along with Heaths, Sedgelands, Shrublands and Closed Forest. The distribution of communities is related to drainage, aspect, slope and soil depth. Many of the communities show considerable variation and intergrade along common boundaries. A number of specialised communities are thought to be restricted to the reserve.\r\n\r\nVIS_ID 4707

1999年，约翰·T·亨特博士受澳大利亚国家公园与野生动物服务（NPWS）北部台地区域委托，同步开展了巴尔德岩国家公园与博诺博诺国家公园（Boonoo Boonoo National Park）的植被测绘工作，该测绘成果于2006年完成修订。巴尔德岩国家公园坐落于滕特菲尔德（Tenterfield）以北约20公里处，由两片独立区域组成。

巴尔德岩国家公园的植被已完成系统性描述与制图（比例尺1:25000），该成果为上述两处保护区土地调查的第一部分，调查第二部分将纳入新获批收购的土地。研究基于PATN分析划定了10个植被群落，并参考既往调查界定了1个特殊植被群落。上述11个植被群落均通过野外实地验证（ground truthing）、航空影像解译（air photo interpretation）及海拔数据完成制图。多数群落为高大开阔林（Tall Open Forest）结构，此外还分布有林地（Woodlands）、灌丛（Heaths）、莎草沼泽（Sedgelands）、灌丛地（Shrublands）及封闭林（Closed Forest）。植被群落的空间分布与排水条件、坡向、坡度及土壤厚度密切相关。多数群落在共通边界处存在显著变异与过渡特征，部分特殊植被群落被认为仅局限于该保护区范围内。
