4.
Local native trees support more species of native invertebrates than exotic
trees.

In turn, invertebrates are important sources of food for many native
birds and mammals.
5.
Exotic species may colonise areas well beyond planted areas and eventually
become environmental weeds elsewhere in agricultural landscapes. Such
environmental weeds can be expensive to remove and in some cases virtually
impossible to control.
6.
Plantings established with native trees are more resilient to fire. The vast
majority of native plants have well-developed abilities to recover naturally after
fire, particularly if they are well established (e.g. greater than 10-15 years old)
before they are burned. This is in marked contrast to most exotic species of
plants.
7.
Incentive payments to establish plantings may not (and should not) be
forthcoming if revegetated areas are dominated by exotic or invasive plant
species.
8.
Locally native plants are more likely to regenerate naturally which means a tree
planting will be there for the long term.
