Regeneration success
Regeneration success of eucalypt areas is reported after
they are three years old, while swamp blackwood, rainforest
and Huon pine forest coupes are reported after they
are five years old. Regeneration success is determined
by undertaking regeneration surveys. The percentage
of assessed plots that were stocked is reported for each
regenerated area. For each forest type, there is a set
minimum stocking standard that needs to be achieved. This
approach complies with the recommended methodology
for national regeneration success monitoring.
For the 2007/08 year, 10,205 hectares of native forest
regeneration reached regeneration success reporting age.
Of this area 98 per cent achieved the required stocking
standards. This is an increase of three per cent on the
five-year average (95 per cent) and exceeds the Forestry
Tasmania target of 85 per cent of harvested area being
regenerated to standard.
Three areas totalling 197 hectares did not meet the
stocking standards. Two of these areas were assessed
to have contained sufficient stocking to be considered
as ecologically stocked or be able to maintain wood
production at a reduced rate. The third coupe contained
a large understocked patch (14 hectares) that will be retreated
in the 2008/09 year so that it complies with the
stocking standards.
