Weed Potential 
As a weed Desert Ash is highly invasive in regions of moderate rainfall appearing in habitats including woodlands or along water courses and in drainage lines. It forms dense stands that reducing the regeneration of native tree or shrub seedlings and understorey plants.
 
It prefers an open sunny position on moist fertile soils or soils that are periodically inundated. It can tolerate dry periods once established. Trees can produce seeds with in 6-years and can live for up to 80 years. It is fast growing with seedlings germinating in an open sunny position. 

Seeds are produced prolifically in spring and maturing in late summer and remain dormant for up to 4-years. The seeds are dispersed by wind, water and in pruned material. 

Control methods include physically digging out seedlings and small plants when the soil is moist ensuring that the roots are removed as the slender trunks snap off easily and the plant re-shoots from the base. 

Fruiting branches should be bagged and destroyed if possible. Plants can be cut and painted on the stems or drilled and injected in the trunk towards the base with a non-selective herbicide during early autumn. 

Follow up applications may be requires as the tree can re-shoots. Young plants or seedlings may be sprayed with a non-selective herbicide during spring while the plant is actively growing.
