Botrytella reinboldii (DD)

Observations of Botrytella reinboldii were collected from the Baltic Sea area for HELCOM Red List species list. The HELCOM Red List of Baltic Sea species in danger of becoming extinct (2013) is the first threat assessment for Baltic Sea species that covers all marine mammals, fish, birds, macrophytes (aquatic plants), and benthic invertebrates, and follows the Red List criteria of the International Union for Conservation of Nature (IUCN). Almost 2800 species were considered in the Red List assessment and about 1750 were evaluated according to the IUCN Red List criteria. Botrytella reinboldii has been placed to the Red List category of Data Deficient (DD) species. Dataset for download contains spatial grid of the Baltic Sea. Distribution of the species can be found in corresponding name column. Values are coded: 0 = no observations 1 = present before year 1995 or in 1995 2 = present after year 1995 3 = present before and after year 1995本数据集针对瑞氏葡萄囊藻（Botrytella reinboldii）的观测记录采集自波罗的海海域，用于波罗的海海洋环境保护委员会（HELCOM）红色名录物种清单的编制工作。 《2013年波罗的海濒危物种HELCOM红色名录》是首个覆盖波罗的海全部海洋哺乳动物、鱼类、鸟类、大型水生植物（macrophytes，水生植物）以及底栖无脊椎动物的波罗的海物种威胁评估报告，其评估标准遵循国际自然保护联盟（IUCN）的红色名录等级准则。 本次红色名录评估共涉及近2800个物种，其中约1750个物种依据IUCN红色名录标准完成了正式评估。 瑞氏葡萄囊藻（Botrytella reinboldii）被归入数据缺乏（Data Deficient，DD）等级的红色名录物种类别。 可供下载的数据集包含波罗的海海域空间网格数据。该物种的分布信息可在对应名称列中查询。数据编码规则如下： 0 = 无观测记录； 1 = 1995年及之前存在观测记录； 2 = 1995年之后存在观测记录； 3 = 1995年前后均存在观测记录。
