An error has been identified in the written answer given on 06 February 2018.
The correct answer should have been:
Animal and Plant Health Agency (APHA) spent £3.8m on invasive non-native species in 2016/17 including both direct costs and apportioned support staff and overheads.
APHA do not keep the split as requested but can further subdivide the cost between direct costs (£2.2m) and apportioned support staff and overheads (£1.6m).
Biosecurity and control of invasive non-native species are devolved matters.
In England in 2016/17 the government spent an estimated total of £922,000 on biosecurity measures relating to invasive non-native species.
The overall cost can be apportioned as £145,000 for policy functions, £90,000 on risk analysis, £335,000 for early warning and rapid response measures, £210,000 on coordination, £80,000 on communication and awareness raising activities, and £62,000 on research.
