Human resources for research

Despite the establishment of Ensis, research capacity in forestry and forest products in coming decades may be constrained not least by significant reductions in the staff numbers of traditional research providers, an increased emphasis on short-term projects, and the diversion of staff from research projects to monitoring and consultancies. Many of the skilled personnel who have been ‘downsized’ have remained on call in the workforce as contractors or consultants, but their former contributions to institutional memories and the mentoring of younger colleagues are being lost, and their effectiveness is inevitably being eroded by increasing age and isolation. Future research capacity is also threatened by a marked down-turn in undergraduate numbers (Kanowski, 2006) a problem in many countries (described in Chapter 5). Although contemporary forestry problems may often be best addressed by teams including specialists from other disciplines, the consequent broadening of the potential pool of talent may be insufficient to meet national needs at a time both of expansion of the forest industry and of threats to it.

Some topics for research are described briefl y below.

New horizons for plantations

In Australia, the large area of maturing eucalypt plantations established in the last decade for fibre production presents a significant challenge for harvesting and marketing, as well as an opportunity to establish important processing capacity in Australia. The ability to grow commercially-successful plantations in the seasonally-dry tropics of northern Australia, and in low-rainfall areas in southern Australia (e.g. some areas now used for wheat) would be valuable: in the first case, to expand and diversify regional economies (Underwood, 2006), and in the second to ameliorate land degradation resulting from salinisation (Maslin and McDonald 2004).  

The hardwood dilemma

Australia and NZ have been very successful in developing timber industries based on softwood plantations, and more recently short-rotation hardwoods for fibre. However, research is still needed into the technical, economic and commercial challenges of establishing durable hardwoods from Australian native forests in plantations (Kile, 2005)

Forest protection and sustainability

Both native forests and plantations may be threatened by pests, diseases, weeds, droughts and fires. Sustaining productivity will require ongoing research in stand management, nutrition and genetics.

Water and climate change

Climate change is expected to have a profound effect on Australasian forests and on the research necessary to maintain them. In Australia, it is expected that an already very variable climate will become even more erratic, and that there will be more prolonged droughts and higher temperatures over extensive areas. These changes will certainly affect forest growth, and are likely to increase vulnerability to pests and diseases, and particularly fires. In some regions of southern Australia droughts and fires have already

significantly damaged the forest estate. The infl uence of forests on the quality and quantity of water yield from catchments has come to public attention as most cities in Australia face significant water shortages. Competition for water is increasing (see for example Clifton et al. 2006, and Nambiar and Ferguson 2005) and research on forested catchments is urgently required into management practices to maintain or increase water yield.
