During harvesting of fire<br />
salvage, the buffer and<br />
filter prescriptions must be<br />
increased beyond the<br />
measures listed for site<br />
with high or very high<br />
water quality risk.<br />

*Slope should be regarded as the average slope of the coupe area in the vicinity of the<br />
water body and within the catchment<br />
* The width of buffer and filter strips must be measured from the edge of the saturated<br />
zone (at time of harvesting) or channel (whichever is greater), on each side of the<br />
waterway.<br />
* The width of buffer and filter strips must be measured in the horizontal plane.<br />

Quality,<br />
River Health<br />
and Soil<br />
Protection<br />
Water quality and river<br />
health must be protected<br />
by maintaining buffers<br />
and/or filter strips (to each<br />
side of the waterway).<br />
The location of buffers<br />
and filter strips must be<br />
easily distinguishable in<br />
the field, either through<br />
the use of geographic<br />
features or marking<br />
Filters must not be less<br />
than the widths specified in<br />

Trees may be felled from<br />

felling of trees into filter<br />
strips must be avoided<br />
where possible.<br />

Disturbance to soil and<br />
understorey vegetation<br />
from harvesting operations<br />
in filter strips must be<br />
minimised. Directing trees<br />
to fall out of filter strips<br />
may reduce soil<br />
disturbance.<br />
Code guidelines followed.<br />
