This website presents broad-scale, climate-based risk maps of native and non-native forest insects and diseases in Canada. This effort involves the collation of historical and recent field observations and the analysis of this data in relation to climate (see here for details on associated climate models). For species where data availability permits, users can also explore the intersection between climate suitability and host biomass across Canada (from Beaudoin et al. 2014) – providing a coarse indication of possible forest resources at risk.
