The Areas With Bark Beetle Mortality (2000-2021) data layer maps areas with bark beetle mortality over the years 2000-2021 and was derived from Forest Health Protection's dataset on 'cumulative areas with bark beetle mortality'. Detection surveys are the primary method of collecting data on the health of treed areas affected by insects and diseases. Aerial and ground surveys are conducted annually.
