Vegetation - Eastman and Hensley Lakes [ds1057]

The California Native Plant Society (CNPS) Vegetation Program produced a vegetation map and classification for approximately 35,000 acres including the town of Raymond and extending to Eastman Lake to the west, and surrounding Hensley Lake to the south (Madera and Mariposa Counties, California). CNPS delineated vegetation polygons using 2012 NAIP aerial imagery and CNPS survey data collected between 2008 to 2010, as well as field reconnaissance in 2014. The mapped area includes mostly private lands, as well as the properties adjacent to Eastman and Hensley Lakes which are managed by the Army Corps of Engineers. The vegetation classification of 47 native vegetation alliances and semi-natural stands was based on data within the southern Sierra Nevada Foothills Ecoregion across a larger area of approximately 300,000 acres including portions of Mariposa, Madera, and Fresno Counties. The vegetation map resulted in 31 types of mapping units including alliance-level vegetation types from the floristic classification within the focused study area. More information can be found in the mapping report, which is bundled with vegetation map published for BIOS here: https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/1000_1099/ds1057.zip The report can also be downloaded separately here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=101387.加州本土植物学会（California Native Plant Society, CNPS）植被项目组制作了一套覆盖约35000英亩范围的植被地图与分类数据集，该区域涵盖雷蒙德镇，西至伊斯特曼湖，南至毗邻亨斯利湖的周边区域，涉及美国加利福尼亚州马德拉县与马里波萨县。 CNPS采用2012年NAIP（National Agriculture Imagery Program，美国国家农业航空影像计划）航空影像、2008至2010年采集的CNPS调查数据，以及2014年的野外踏勘数据，勾绘得到植被多边形区域。 该制图区域以私有土地为主，同时包含由美国陆军工程兵团管理的伊斯特曼湖与亨斯利湖周边权属地块。 本次植被分类涵盖47种本土植被群丛（alliance）与半自然林分，分类依据取自内华达山脉南部丘陵生态区约30万英亩的更大范围数据集，覆盖马里波萨县、马德拉县与弗雷斯诺县的部分区域。 本次植被地图共生成31类制图单元，其中包含聚焦研究区内基于植物区系分类得到的群丛级植被类型。 更多详细信息可查阅配套制图报告，该报告与为BIOS项目发布的植被地图打包发布，下载链接为：https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/1000_1099/ds1057.zip；该报告也可通过以下链接单独下载：https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=101387。
