Special Areas of Conservation (SAC) interest feature details

Special Areas of Conservation (SACs) are strictly protected sites designated under the EC Habitats Directive. This series of datasets is derived from the UK wide data submitted to the EU Commmission. A substantive update was done as part of the Standard Data Form updating exercise on 22 December 2015 (Tranche 50) . It contains details for each interest feature (habitat or species) for each and every SAC - there is one row in the dataset for each combination of individual site and interest feature. The data here are for the following sections of the standard data form.
This dataset relates to sections 3.1 and 3.2 of the Standard Data form

Notes on specific columns:

IS_MARINE
0 = Not considered to be a Marine Protected Area
1= Marine Protected Area.

DESIGNATION_STATUS_CODE
cSAC = submitted to the EU as a candidate site but not yet adopted by the EU as an SCI
SCI= Site of Community Importance - a status conferred by the EU Commission.
SAC = Designated SAC. The final stage in the process

PRIORITY
1= YES 0 = NO

Hectares
Values adjusted because whole sites area figures have changed due to GIS updates and habitat % cover estimates have been kept the same.

habcover: % of site

DATA_QUALITY
G = âGoodâ (e.g. based on surveys); M = âModerateâ (e.g. based on partial data with some extrapolation); P = âPoorâ (e.g. rough estimation); DD = data deficient (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

SPECIES_GROUP
A =Amphibians, B = Birds, F = Fish, Fu = Fungi, I = Invertebrates,L = Lichens, M = Mammals, P =Plants, R = Reptiles

Archived versions of this dataset are also available as part of a time series. These may be useful in determining how many sites there were at a given point of time, and also how some of the detailed information might have changed over time. Note that the data columns in this series of datasets were revised slightly in December 2015.
Each archived version corresponds to a European submission. A record of the changes made at each submisison is shown here.

特別保護區（SACs）系依据欧盟栖息地指令严格保护的指定地点。本系列数据集源自提交给欧盟委员会的英国全国数据。作为标准数据表更新练习的一部分，于2015年12月22日（第50批次）进行了实质性更新。该数据集包含了每个SAC中每个兴趣特征（生境或物种）的详细信息——对于每个SAC与每个兴趣特征的组合，数据集中都有一行。此处数据涉及标准数据表的下述部分。

关于特定列的说明：

IS_MARINE
0 = 不被视为海洋保护区
1= 海洋保护区。

DESIGNATION_STATUS_CODE
cSAC = 已提交给欧盟作为候选地，但尚未被欧盟采纳为SCI
SCI= 欧洲委员会授予的具有社区重要性的地点。
SAC = 指定的SAC。流程的最终阶段。

PRIORITY
1= 是 0 = 否

由于GIS更新导致整个站点面积数据有所变化，因此进行了调整，而栖息地覆盖率估计值保持不变。

habcover: 站点百分比

DATA_QUALITY
G = 良好（例如，基于调查）；M = 中等（例如，基于部分数据并进行了某些外推）；P = 差（例如，粗略估计）；DD = 数据不足（仅在无法进行种群大小粗略估计的情况下使用此类别，在这种情况下，种群大小字段可以保持为空，但“丰富度类别”字段必须填写）

SPECIES_GROUP
A = 两栖动物，B = 鸟类，F = 鱼类，Fu = 真菌，I = 无脊椎动物，L = 地衣，M = 哺乳动物，P = 植物，R = 爬行动物

本数据集的存档版本也作为时间序列的一部分提供。这些存档版本可能有助于确定在特定时间点有多少个站点，以及一些详细信息可能随着时间的推移如何发生变化。请注意，在2015年12月，本系列数据集中的数据列略有修订。每个存档版本对应于一次欧洲提交。每次提交所做的更改记录如下。
