This layer shows the extent of Statutory Plant Health Notices (SPHN) issued by Scottish Forestry in Scotland. The SPHN extent defines the boundary within which the full conditions and biosecurity measures of the SPHN apply - for smaller woodlands this is usually the external boundary of the woodland.  An SPHN typically covers a 250m buffer around a confirmed infected site.  The layer includes both active notices and older ones which have expired. It includes SPHNs issued for any pests and diseases, although the majority are for Phytophthora ramorum.
