of this project are to:
guidelines for the preparation and management of seedling stock during
weed management systems that minimise the use of herbicides, including
the use of non-competing species as cover crops;
pruning, thinning and spacing systems that are suitable for converting
industrial pulpwood plantations to clearwood regimes and for farm forestry;
the benefits and costs of trees on farms, and the real or perceived
barriers to the adoption of commercial forestry on part or all of the
farm enterprise, and develop an enhanced understanding of the factors
which determine regional timber supply.
induction of cold-induced photoinhibition of E. nitens decreased
photochemical efficiency and chlorophyll, and increased xanthophyll
cycle conversion ratio and xanthophyll cycle pigments. Anthocyanin levels
gradually increased except in non-shaded, nutrient-deprived seedlings
that had high levels before the induction of photoinhibition. The findings
strongly indicated that anthocyanins might provide a photoprotective
shelters when placed around seedlings in the field to lower light intensity
will alleviate cold-induced photoinhibition and maximise growth during
winter, but limit growth during warmer periods and therefore overall
nitens and E. globulus seedlings can adjust their leaf angle.
Larger leaf angle was associated with decreased levels of incident photon
flux density and also with increased levels of photoinhibition induced
by nitrogen deficit. Leaf angle may play a role in photoprotection of
melanoxylon (blackwood) can compensate for the removal of crown
area during green pruning by increasing its photosynthetic capacity
in the upper two-thirds of the crown. Form pruning that removes foliage
solely from the upper reaches of the crown is likely to reduce this
increase in capacity and have a greater effect than lift pruning on
the growth of blackwood.
- For commercial
nurse-crop species like E. nitens and Pinus radiata, closer
spacing than is used conventionally can produce better blackwood form.
However there is a tendency for slower blackwood growth, meaning that
management of blackwood under systems such as the five-row nurse treatment
must be vigilant to avoid suppression of blackwood growth.
- Lack of
post-planting weed control has been a major deficiency leading to the
poor success of revegetation programmes in the Midlands of Tasmania.
Improved record keeping in these programmes would benefit landowners,
extension officers and research scientists working in this area.
- An examination
of the 'Drier Tasmanian Demonstration Areas' project indicated that
it had been successful in expanding commercial plantation establishment
into areas not traditionally or currently involved in the forest industries.
Demonstration sites are an important element in fostering the establishment
of trees on farms.

partnerships and seeing forestry's pluralism (i.e. reliance on many
and varied stakeholders) as an opportunity to engage more widely amongst
communities about forestry's contribution to the social, economic and
environmental fabric of society.
