remnant vegetation or planted native vegetation may provide additional habitat for
species and/or facilitate the movement of organisms between habitat patches.
Scattered paddock trees are a critical type of remnant native vegetation on a

(see Chapter 4), and we have found that plantings established around
paddock trees can significantly increase their suitability for bird species like the
White-browed Woodswallow and the White-plumed Honeyeater.

The
combination of large old remnant paddock trees and adjacent young, densely
planted trees may increase the range of places where birds can find food or
construct a nest. The value of paddock trees as nodal points around which to
establish plantings needs to be weighed against the potential for natural
regeneration to occur around paddock trees if processes like the intensity of
