It is likely more planting locations will be identified following weed management work. The removal
of the densely populated areas of weeds will provide the opportunity for greater numbers of
NJKHT to be planted and established.


The planting locations and descriptions are shown in the attached planting opportunity plan.



Proposed Planting Strategy:

To achieve the projected 32 individual trees established to maturity, a planting ratio of 3:1 should
be implemented. Planting three trees at 1.5 – 2m centres in a group will promote competition for
light and increase tree height at a greater rate. Over time, one of the three trees will likely become
dominant and suppress the others. The suppressed trees will still provide amenity and ecological
services to the mid-storey canopy. The planting opportunity plan provides the proposed planting
location and mixes for each of the species.


The proposed pruning will not significantly alter the combined canopy form. The pruning is minor
and should only be noticeable when standing inside the site directly under the area of pruning.


The new trees will quickly fill the available space due to their juvenile growth rates, and the three
identified species have greater annual extension growth than the neighbouring Bribie Island
Pines. The site's wind exposure will limit the ultimate size of the planted trees. When growth
exceeds the shelter of the adjoining Bribie Island Pines, the growth elongation will reduce
because of the wind exposure. The trees will continue to increase in size. However, growth will
be much slower, and therefore, this exposure will determine the ultimate crown spread. The trees
in the lower area of the site will tend to be taller with greater crown spread when compared to
trees higher on the slope. The texture of the overall canopy will not change; the proposed planting
will fill in the openings in the current canopy.
