The CSIRO Division of Forestry has its headquarters in Canberra with regional groups in Hobart, Mt. Gambier and Perth. The Division has a staff of 170 and a mission to increase the economic and environmental benefit to Australia by improving the productivity and management of the nation's forests. The Division's research is organised in four programmes: Australian Tree Resources, Hardwood Plantations, Regrowth Forest Management and Softwood Plantations.
Research on non-wood forest products (NWFPs) is largely within the Australian Tree Resources programme, where the objective is to explore, sample, evaluate and distribute the genetic resources of trees of actual or potential value for planting in Australia and other countries.
NWFPs which are significant in Australia include: honey and pollen production, wild flowers and tree foliage, seed, nut and other tree crops, essential oils, sandalwood, craftwood, broombush, Christmas trees, drugs, tannins, gums and resins. Many of the existing NWFPs industries rely on exploiting natural forests, but there is increasing attention being paid to establishing man-made forests for this purpose. The human and financial resources available for work on NWFPs at CSIRO Division of Forestry are limited, dictating a high degree of selectivity in the projects undertaken and dependence on a high level of external support. Despite these constraints, a significant programme has developed within the Division, focused mainly on the Division's strengths in species selection, genetic improvement and beneficial symbionts. This paper provides a brief review of current projects on NWFPs at CSIRO's Division of Forestry.
The seeds of about 50 Australian dry-zone Acacia species are traditional food of Australian Aboriginal people. Nutritional and toxicological analysis of seeds shows them to be quite high in protein, fat and carbohydrates, and to have low levels of known toxic and anti-nutritional factors. Recently in Australia, the seeds of several acacias have become popular ingredients of "bush tucker" (i.e. use of indigenous species of both plant and animal as food) preparations such as biscuits and coffee. Three species, Acacia colei, A. cowleana and A. tumida, have grown rapidly in trials in semi-arid regions of sub-Saharan Africa. In the 450-700 mm annual rainfall zone of the Sahel, wide-spaced plants can produce heavy crops of seed annually. Trials conducted at Maradi, Niger have shown that seed of A. colei is easily processed using local technology and can be used to prepare palatable foods (Harwood, 1994).
In August 1991, CSIRO Division of Forestry organised a workshop to discuss the merits and methods of developing the human food value of Australia's dry-zone Acacia species (House and Harwood, 1992). Work so far has concentrated on extending the knowledge base for species with human food potential, including their Aboriginal use, ecology and botany, nutritional value and performance in field trials both within Australia and outside (see Annex 1.A). Priorities for future research include feeding trials with laboratory animals, medically monitored dietary trials with human volunteers and field experiments to determine appropriate silvicultural strategies for maximum seed yields.
Cut flowers and foliage constitute a $A 150 million industry in Australia today, with significant growth potential from expanding exports. A small project is under way at CSIRO Division of Forestry to assess the potential of eucalypts as a source of material for the cut-flower industry. A growth retardant, paclobutrazol, is being used to stimulate the formation of large numbers of flowers in potted specimens of species with colourful and decorative floral parts (see Annex 1.D.1).
The Australian Centre for International Agricultural Research (ACIAR) is currently funding a project involving CSIRO Division of Forestry in Perth, the Chinese Academy of Forestry and researchers in the Philippines to improve the performance of plantation-grown eucalypts through the introduction of beneficial mycorrhizal fungi that enhance eucalypt growth. To bolster dwindling supplies of fungi from native forests in China and the Philippines, the team is also researching the potential for introducing new species of edible fungi from Australia that are compatible with eucalypts and acceptable to the palate.
The Division is also assisting in the development of a black truffle-growing industry in Tasmania, aiming to supply truffles to the world market. Details of these projects are summarised in Annex 1.B.
Essential oils are produced throughout the world. A significant proportion is produced in the United States and Europe, as well as Brazil, India, China and a number of African and Southeast Asian nations. Australia, a net importer of essential oils and oil products, has a relatively small industry with considerable scope to expand. Australian native plants used for essential oil production since early times include Eucalyptus , Australian tea tree (mainly Melaleuca alternifolia), Australian sandalwood (mainly Santalum spicatum), huon pine and boronia. Other essential oil crops that have been developed in Australia during the last two decades include basil, blackcurrant, caraway, citrus oils, fennel, lavender, peppermint and spearmint.
Research on essential oils at CSIRO Division of Forestry is directed at selection and improvement of yield and quality of oil in woody plant species with potential for commercial exploitation of their oils. Specific projects are briefly described below and in Annex 1.C.
Commercial production of Eucalyptus oil in Australia began in 1852, in Victoria near Dandenong. Eucalyptus oils were used as medicinal products, for various industrial purposes and in perfumery and were produced from natural forests. Annual production in Australia reached a peak of about 800 tonnes in the 1950s and has since declined to less than 100 tonnes against stiff overseas competition from oils produced as a by-product of the timber industry (Boland et al., 1991).
Current research in Australia is focused on the excellent solvent properties of 1,8-cineole, a major component of medicinal-grade Eucalyptus oils, for industrial applications like degreasing, where it may replace ozone-depleting, petrochemical-based solvents. The expectation that the demand for oil may increase dramatically (300 times) if this new market develops has led to a resurgence of interest in production of Eucalyptus oil, especially in Western Australia (Barbour and Bartle, 1993).
Species included in seed collecting and selection and breeding programmes at CSIRO Division of Forestry for their oil-yielding potential are E. camaldulensis, E. polybractea and E. radiata. Part of the work on E. camaldulensis is based in Thailand, where the Division, as a component of a project funded by ACIAR, is assisting the Thai Royal Forest Department to assess the potential of producing Eucalyptus oil locally (Annex 1.C.4). The book, Eucalyptus leaf oils: use, chemistry, distillation and marketing, was prepared by Divisional staff in collaboration with University of New South Wales and private companies (Boland et al., 1991). Papers highlighting the work done include Doran and Brophy (1990), Doran and Matheson (1994) and Doran and Bell (1994).
Several melaleuca species produce essential oils of commerce. Cayuput oil from M. cajuputi in Indonesia and Niaouli oil from M. quinquenervia in New Caledonia are among the best known. Australian tea tree oil from M. alternifolia has a rapidly expanding world market as a natural antiseptic. Once produced solely from natural stands in northern New South Wales, production since the 1980s has come increasingly from fast-growing, intensively managed plantations (Murtagh, 1991). Production of Australian tea tree oil is expected to reach 120 tonnes in 1994.
The Australian tea tree oil industry has recognised the need for enhanced efficiencies to maintain its position as the major world producer of this type of oil. The yields of oil from established plantations are variable; there is much scope to improve both the amount and quality of the yield through selection and breeding (Butcher et al., 1994). Since May 1993, CSIRO's Division of Forestry has been assisting in a M. alternifolia breeding programme with the aim of increasing oil yields of new seedling plantations by 30 percent in five years.
The Division of Forestry is also involved in the screening of Melaleuca species and their close relatives for interesting oils with commercial potential. Part of this work is based in the Mekong Delta region of Viet Nam where, as a component of a project funded by ACIAR, one indigenous and several exotic Melaleuca species have been established in field trials to assess their potential for both wood and oil production.
A range of other Australian tree species are currently under investigation as potential essential oil crop plants (e.g. species of the genus Backhousia).
The honey and pollen industries are important Australia-wide in all regions and climatic zones. Much of the industry is based on native species (predominantly eucalypts), but exotic and native crop plants and pasture and weed species also provide a large nectar supply for the industry. The gross value of honey production in Australia is estimated to be in the order of $A 32 million, not including the value of incidental pollination of many agricultural crops. Exports mainly to the United Kingdom, Germany and the United States earn about $A 12 million. Australia's beekeeping industry also produces 600 tonnes of beeswax annually.
Work at CSIRO Division of Forestry, as summarised in Annex 1.D, has concentrated on methods of inducing and enhancing flowering in various temperate and tropical tree species. The aims of the work are to reduce generation intervals in breeding programmes and encourage greater seed production from seed orchards of important commercial species such as Eucalyptus nitens (Moncur et al., 1994). Research at the Division has shown that the growth retardant, paclobutrazol, previously used in horticulture, can be used successfully in forestry. Following treatment of E. nitens trees with paclobutrazol at 2.5 years of age, flower buds were observed in year three, flowering occurred in year four and mature seed was harvested in year five - half the normal generation interval. A combination of additional treatments, including grafting, pot culture, temperature changes and espalier techniques, has further reduced generation time. The work of the Division on tropical tree species, such as that taking place in Indonesia with funding from ACIAR, uses similar technology to that developed for eucalypts. The Division is also assessing the potential of bees to enhance pollen flow in seed orchards, thereby improving the yield and quality of seeds in addition to providing honey as a by-product of seed orchard management.
The Australian woody flora is an extensive and diverse resource which has proven to be very valuable in afforestation programmes, both in Australia and in other countries. Today Australian trees are of considerable social and economic importance throughout the warm temperate and tropical regions of the world. Many species of the genus Eucalyptus grow quickly and can produce large quantities of wood for both industrial and community use. They are now the most widely planted hardwood trees in the world. Other widely-used genera include acacias and casuarinas: nitrogen fixing trees which are capable of tolerating harsh sites while yielding a variety of products, including timber, pulp, fuelwood, pollen in honey production and tannins. Estimates of the areas planted to species of these three genera globally are 9 million ha of eucalypts, 1.7 million ha of acacias and 1.4 million ha of casuarinas (Vercoe, 1993).
Tree seed exports from Australia are estimated to be in the order of 25-30 tonnes annually, with a commercial value of about $A 9 million (Doran and Gardiner, 1992). The Australian Tree Seed Centre (ATSC), part of CSIRO Division of Forestry, plays an important role in this industry. The Centre collects and supplies high quality seed of Australia's woody flora, with special emphasis on range-wide provenance collections and lots from widely spaced individual trees for research purposes. Currently, seed of over 1,000 species is held in store. ATSC responds to over 2,000 enquiries every year and dispatches several thousand seedlots to researchers in Australia and about 100 other countries (Vercoe and Midgley, 1993). ATSC manages the Seeds of Australian Trees Project for ACIAR. This project aims to identify and assist in the introduction and domestication of Australian tree and shrub species to meet fuelwood, agroforestry and industrial needs of developing countries. The research undertaken by the Centre generally complements the service role. Collaborative research projects cover several disciplines, including taxonomy, breeding strategies (including establishment and management of seed orchards), quantitative genetics, studies of genetic variation including use of biochemical markers, investigations of a range of physiological attributes (such as salt and waterlogging tolerance) and studies of pests and diseases of Australian trees. Several current ATSC projects are summarised in Annex 1.E.
CSIRO Division of Forestry is presently involved in only one project concerning resins (see Annex 1.F). ACIAR is providing limited support for the gathering of baseline data on the production of benzoin resin from Styrax tonkinensis, which is endemic to northern Laos and Viet Nam (Pinyopusarerk, 1994).
Tanning greatly increases the durability, water resistance and flexibility of animal hides, which if not treated would decay rapidly. The bark of Acacia mearnsii, a tree native to southern Australia, is one of the most important tannin sources in the world. Australia, once the sole producer of wattlebark tannin, now imports all its supplies from other countries, including South Africa, Brazil and Kenya. Currently Australia annually imports about 7,000 tonnes (about $A 10 million) worth of wattlebark tannin. Of that, an estimated 600 tonnes is used in the leather industry while the major use is as part of the resin component of wood-adhesives for particleboard flooring, plywood and finger-jointing (Searle, 1991).
CSIRO Division of Forestry and collaborators are presently involved in an ACIAR-funded project in China and Viet Nam to assist agencies in those countries to cultivate and improve A. mearnsii and other Australian acacias for wood and tannin production. In Australia, the Division is involved in similar work in Western Australia and in the Australian Capital Territory (Searle, pers. comm.). Summary details of these projects are given in Annex 1.G.
