<strong>Red</strong>gum and Stringybark trees were cut for railway sleepers and construction timber<br />
from the area including the Round Waterhole NFR until the 1940s. (Kuhl pers. comm.<br />
1991)<br />
There has been no commercial cutting of trees in either area since these times.<br />
3.2.3 Wildfire<br />
Uncharred reject sleepers, cut stumps and tree tops remaining after the last sleeper<br />
cutting operations provide evidence that there has been no significant wild fires at<br />
Round Waterhole for 50 years or more. A similar lack of fire effects is evident at<br />
Muddy Flat where it is believed that no wild fires have occurred at least since 1928.<br />
(Pannell pers.comm.2000).<br />
3.2.4 Prescribed Burning<br />
There is no record of either Reserve being burnt deliberately to reduce the fire<br />
hazard. Prescribed burning has generally been applied to Stringybark and Bracken<br />
vegetation associations where fuel loads, fire intensity and the potential to produce<br />
and deposit wind-borne flaming material ahead of a fire is high. These <strong>Reserves</strong> are<br />
dominated by more open <strong>Red</strong>gum woodland over a ground cover of sedge and grass<br />
species considered to be relatively less hazardous.<br />
Prescribed Burning Policy<br />
In 1971, in recognition of the conservation value of the native forests and the limited<br />
knowledge of the ecological impact of repeated burning, <strong>Forest</strong>rySA (then Woods<br />
and <strong>Forest</strong>s Department) developed a prescribed burning policy with the objective of<br />
carrying out low intensity mosaic burning in native forests at intervals of 3 - 8 years.<br />
Some areas were scheduled for longer intervals between burns, and certain areas<br />
were excluded from burning to provide scientific reference (benchmark) areas.<br />
The policy was reviewed in 1985, 1992 and 1998, continuing the emphasis on habitat<br />
management.<br />
The objectives of <strong>Forest</strong>rySA's current Prescribed Burning Policy which schedules<br />
burning of varying intensity and interval in selected compartments while maintaining<br />
other compartments as unburnt reference areas, is to:<br />
create and maintain floristic and structural diversity<br />
optimise species presence and minimise further local extinctions<br />
reduce wildfire intensities to improve survival and re-colonisation opportunities<br />
protect assets by fuel reduction in limited strategic areas.<br />
The policy recommends alternating prescribed fire intensity from low to high for<br />
consecutive fires in the same compartment. The seasonal timing of the fire, ie,<br />
spring or autumn may also vary depending on assessed vegetation diversity and<br />
development and the requirement for species regeneration.<br />
The minimum interval between burns has been based on the reproductive period of<br />
the major over-storey species Eucalyptus baxteri which has been established to be<br />
