RHS rosemary beetle (Chrysolina americana) monitoring
The data set consists of records for the rosemary beetle (Chrysolina americana) for the UK gathered by the Royal Horticultural Society, from members of the Society and the general public.
Data have been collected as part of the surveying work of the Royal Horticultural Society to establish the distribution and spread of the rosemary beetle, an invasive garden pest of rosemary (Rosmarinus), lavender (Lavandula) and related plants, which became established in the UK during the 1990s.
Data are from 1994 onwards when the rosemary beetle became established in the UK. A majority of records post May 2008 are via the web based form.
The survey aims for UK and Ireland coverage. A majority of records are at 1km or better resolution.
Data quality is good, but coverage pre May 2008 is predominantly limited to Royal Horticultural Society members.
Records are verified by Andrew Halstead, Andrew Salisbury, Anna Platoni or Hayley Jones based on samples or descriptions provided to the RHS Advisory Service or on the on-line form. Grid references are checked against site names.
Records of the rosemary beetle have been collected via the Royal Horticultural Society Advisory Service (predominantly from RHS members) and from the general public via an on-line recording form on the project website http://www.rhs.org.uk/Science/Plant-pests/Rosemary-beetle or RHS web profile page https://www.rhs.org.uk/advice/profile?PID=555
