The aforementioned dual trunk Queensland Blue Gum appears to be reasonably healthy and
its location does not pose any immediate threat to the building. As an isolated eucalypt its
contribution to leaf litter for bushfire purposes is acceptable but concurrently its size would
add substantially to the local vista.

Recommendations

The safety of people and their residences must always take priority over other
environmental outcomes. In this regard the maintenance of the low fuel zone between the
building and the covenant is critical.

Note also that if a substantial fire occurred within the covenant area then all other
environmental values — which are intended to be fostered - such as fauna, slope stability
and water quality may be affected detrimentally.

Hence the benefits of avoiding a major fire are many fold.

To achieve the management aim of a low fuel zone — and to avoid physical conflict between
vegetation and the building - the following actions should be implemented —

1. Removal of all regrowth eucalypts situated adjacent to the fence.

2. Removal of an unbalanced eucalypt situated approximately 3 metres from the
fence.

3. Removal of hoop pine bark mulch from within the covenant area.

4. Where the hoop pine bark mulch within the property is contiguous with the
covenant area, replace with inorganic mulch, slash pine bark or wood chips.

5. Keep the low fuel zone irrigated if sufficient water supplies are available.

6. Physically remove leaf litter in the low fuel zone every 1-2 months and dispose on
the steeper slopes in the covenant area.

7. Physically remove any dead standing material within 10 metres of the boundary
fence.

Although disposed prunings and other dead material with a nominal diameter of, say, over
15 cm would not contribute to the bushfire hazard in this locality - and would be beneficial
to erosion control — it is recommended that any smaller diameter material and its foliage be
removed from the site for disposal elsewhere.

However any interference with native vegetation within the covenant area always requires
the prior written approval of the Council (Covenantee).

Based on the author’s 40 years’ experience it is subjectively considered that the fuel load
within the overall covenant area at this time does not exceed 10 tonnes/ha as nominated in
the Fire Management Plan. However in the narrow low fuel zone this figure is compromised
by the presence of several eucalypts which should be removed.
