Agroforesty and animals

The introduction of non-native species, of any type, can lead to serious
problems.  Australia is a good example of how bad things can get. 
However, carefully planned and implemented introduction of animals to
forested ecosystems can provide positive benefits.  Sheep and cattle
grazing in young conifer plantations is an excellent example of this
concept and has been successfully implemented in the PNW and in the
southern US.  And probably elsewhere, as well.  This type of management
is also employed in New Zealand where sheep and radiata pine, both
introduced species, are grown together.  It may not be a natural
ecosystem, but it appears to be sustainable, at least for a few
rotations of the trees.
