Vegetation 2015 — Regional Ecosystems — Cover Codes

Regional Ecosystems (Cover Codes) in the Brisbane City Council area. Regional ecosystems (RE's) are vegetation communities in a bioregion that are consistently associated with a particular combination of geology, landform and soil (Sattler and Williams 1999, Vegetation Management Act 1999). Vegetation Cover- Brisbane supports a range of different vegetation cover. These being Remnant and Non-remnant vegetation. Remnant vegetation is further split into regional ecosystems, whilst non-remnant is split into eight. Canal - man-made. Disturbed - predominantly thinned vegetation that no longer meets criteria for remnant vegetation on the basis of canopy cover. Exotic - vegetation dominated by exotic species. Native plantation e.g. Eucalyptus spp., mixed native cabinet timber species. Plantation - predominantly pine plantation (Pinus spp.) and hoop/bunya pine. Regrowth - vegetation that has been cleared and has regrown but still does not meet the criteria for remnant vegetation. Rehabilitation area - actively managed e.g. 2 Million Trees area. Water - anthropogenic water bodies. This dataset was derived from the Queensland Herbarium dataset Regional Ecosystems 2015.本数据集为布里斯班市议会辖区内的区域生态系统（覆盖编码，Regional Ecosystems）数据集。区域生态系统（以下简称RE）是生物区中持续与特定地质、地貌与土壤组合相关联的植被群落（Sattler与Williams，1999；《1999年植被管理法》）。布里斯班的植被覆盖类型多样，包含原生植被（Remnant Vegetation）与非原生植被（Non-remnant Vegetation）两类。其中原生植被可进一步划分为区域生态系统，而非原生植被则分为8个子类：运河（Canal）——人工开挖的河道；受干扰植被（Disturbed）——以疏伐后植被为主，其冠层覆盖度不再符合原生植被判定标准的群落；外来植被（Exotic）——以外来物种为优势种的植被群落；本土人工林（Native plantation）——例如桉属（Eucalyptus spp.）树种混交的本土优质用材林；人工林（Plantation）——以松属（Pinus spp.）及南洋杉/班盖松（hoop/bunya pine）为主的人工林；次生植被（Regrowth）——经开垦后自然恢复但仍未达到原生植被判定标准的植被；修复管护区（Rehabilitation area）——受主动管护的区域，例如“百万植树计划”区域；人工水体（Water）——人为营造的水域。本数据集源自昆士兰植物标本馆2015年发布的区域生态系统数据集。
