T hree mature trees are not far from the Palm Drive sidewalk under the canopy of the great Torrey pine northwest of the intersection of Palm Drive and Arboretum Road. Eucalyptus conjures images of Australia, whose old-growth forests primarily consist of this large, strong tree. Context Hollow-bearing trees are an important breeding and shelter resource for wildlife in Australian native forests and hollow availability can influence species abundance and diversity in forest ecosystems. A persistent problem for forest managers is the ability to locate and survey hollow-bearing trees with a high level of accuracy at low cost over large areas of forest. A final stem density (canopy species) of approximately 500 – 750 stems/ha would reflect a typical mature open forest density. Samples were taken from narrow-leaved ironbark, Eucalyptus crebra, and grey box, Eucalyptus moluccana, in the east and from jarrah, Eucalyptus marginata, and marri, Eucalyptus calophylla, in the west. Canopy conductance, sap flux density and stomatal sensitivity to D All species showed a decline in G C in response to increasing D. Eucalyptus melliodora , a sub-humid species, had the highest normalized maximal G C ( G C / G Cmax ) per unit leaf area compared with all other species measured (Figure 2 a). ex Benth.
