Potential Distribution of Tree of heaven (Ailanthus altissima) in Victoria

This map of potential distribution of Tree of heaven has been produced from CLIMATE modelling and overlayed on suitable overlays with CMA boundaries.

Overlays used:

Land uses: Pasture irrigated and dryland
Broad vegetation types: Dry foothill forest; montane dry woodland; plains grassy woodland; valley grassy forest; coastal grassy woodland; herb-rich woodland; montane grassy woodland; riverine grassy woodland; riparian forest; rainshadow woodland; boinka-raak; mallee woodland; heathy woodland; wimmera mallee/woodland; lowland forest; box-ironbark forest; inland slopes and sedge-rich woodland.

Colours indicate the possibility of Ailanthus altissima infesting these areas. In the non-coloured areas the plant is unlikely to establish as the climate, soil or landuse is not currently suitable.
Red = Very High
Orange = High
Light Green = Medium
Dark Green = Likely
