NSW Koala Baseline Likelihood Map 2016

The map presents the distribution of the likelihood of koala occurrence across NSW based on publicly available data held in the Atlas of NSW Wildlife (www.bionet.nsw.gov.au). The proportion (’p’ column) of koalas (‘Koala’ column) recorded relative to a suite of arboreal mammals is presented in a 10 kilometre grid across NSW. A separate 5 kilometre grid is also available for Koala Management Area (KMA) 1 – North Coast. A measure of the confidence (‘Conf’ column) in the likelihood estimate is also presented. \r\nIn KMA 1 Atlas of NSW Wildlife (Bionet) record data has been supplemented with data from koala spot assessment (SAT) survey along with “rapid SAT” method undertaken where major data deficiencies remained. SAT surveys observation efforts and resulting koala records were used in the same manner as arboreal mammal records. This map can be used to inform the likely occurrence of koalas and informing decisions on mitigation of activities such as native forestry.\r\n\r\nDistance\r\n\r\nKoala Likelihood Mapping 5 km - 5 km Grid Cell\r\n\r\nKoala Likelihood Mapping 10 km - 10 km Grid Cell本地图依托新南威尔士州野生动物图鉴（Atlas of NSW Wildlife，www.bionet.nsw.gov.au）所收录的公开数据，呈现了新南威尔士州（NSW）内考拉（Koala）出现概率的空间分布格局。该数据集以10公里网格为基本单元，展示了考拉（'Koala'列）在所有被记录的树栖哺乳动物（arboreal mammals）中的占比情况（对应'p'列）。针对考拉管理区（Koala Management Area, KMA）1——北海岸区域，本数据集还提供了独立的5公里网格版本。此外，数据中同时包含了考拉出现概率估计值的置信度指标（'Conf'列）。 在考拉管理区1中，新南威尔士州野生动物图鉴（Bionet）的原始记录数据已补充了点位评估调查（spot assessment survey, SAT）所获数据，以及在主要数据缺口区域采用‘快速SAT’方法采集的相关数据。SAT调查的观测投入及其得到的考拉记录，均以与树栖哺乳动物记录完全一致的方式纳入分析流程。 本地图可用于辅助研判考拉的潜在分布区域，为天然林采伐等活动的影响减缓措施决策提供科学依据。 距离 考拉概率分布图（5公里网格单元） 考拉概率分布图（10公里网格单元）
