Manna Gum (Eucalyptus viminalis)
Manna Gum and Narrow-leaf Peppermint are the most widespread and common trees in this forest. The tallest and largest tree on the site is a Manna Gum (dbh 171 cm, April 2013).
Narrow-leaf Peppermint (E. radiata)
Common throughout the forest on Boundary Hill, the largest specimen 161 cm diam. (dbh).
Southern Blue-gum (E. bicostata)
Common along the contour on the lower slopes of the site, where groundwater conditions allow it to dominate and form pure stands. Several very large, old specimens and one tree is the only known den-tree for Greater Gliders on the property (167 cm dbh).
Broad-leaf Peppermint (E. dives)
Only a couple of small stands of this species occur on our property, though more widespread on the northern and western aspects of Boundary Hill.
Swamp Gum (E. camphora)
Strictly speaking, Swamp Gum is not part of Herb-rich Foothill Forest, but it occurs in swampy areas (ground-water discharge sites) at the heads of drainage lines at the. However, some of these springs and bogs are small and ephemeral, and the ecotone is not always distinct.
Blackwood Wattle (Acacia melanoxylon)
This is an uncommon tree in the forest, restricted to the margin of swampy areas and drainage lines.
Silver Wattle (Acacia dealbata)
Silver Wattles are relatively uncommon in the forest proper, concentrated along hte forest edge and a few sites where the canopy has been disturbed (eg. by tree-fall). It’s distribution may be partly determined by the heavy grazing and browsing pressure exerted by high densities of herbivores in the forest.
This small tree is semi-parasitic on eucalypts. It can produce from seed, but can also produce strong suckers from roots. Its foliage is highly palatable to many herbivores; in this forest Swamp Wallabies give these trees a noticeable ‘browse line’. With the heavy browsing pressure in the forest, regeneration is often poor. Though common on roadsides, there are few trees in the forest.
