Forest nursery and seedling production in Leyte and Samar has been an unsustainable development and livelihood undertaking, the focus of which has been solely to serve the usual funded reforestation projects that merely recognize quantity rather than quality of planting materials produced. As a consequence, forest nursery and seedling production has never been established as a sustainable business venture, particularly at the smallholder and local community level. Forest nursery accreditation and planting stock certification is believed to be a sound strategy that can promote high quality forest tree seedling production which would eventually establish the activity as a lucrative livelihood venture especially for smallholders and local communities. The nursery accreditation and planting material certification experiences for fruit and forest trees in Leyte and Samar provide a useful basis and guide in developing and formalizing a system suitable for forest nursery accreditation and planting stock certification. The DA-BPI and DBP accreditation systems can serve as a guide in framing-up the physical standard for a viable and sustainable forest nursery business, with necessary consideration for smallholder operators. Both, however, lack the necessary technical menu and the required best management practices that are crucial in coming up with an improved nursery accreditation and planting stock certification scheme that is achievable and affordable, particularly for smallholder nursery operators.

Field Indicators

The objectives of this study were to develop a systematic approach to identify important soil morphological and vegetation field indicators to better target land management in degraded landscapes in a specific region. The authors were able to link the soil-landscape features to the main soil and water processes operating within the landscape. This information was used to develop a set of field indicators (e.g. soil colour) within a user-friendly soil classification key that is linked to land use options to form the basis of a manual. It was shown that information written in this format helped farmers and regional advisers to identify options for remediation of waterlogged and saline areas and to improve planning at property and catchment scales. The authors identified a series of steps to be taken in producing the manual. Steps 1–5 describe the soil layers and construct them in toposequences, which are then used to map soil types in key surrounding areas. Steps 6–9 involve the local community in developing the manual.The paper provides an account of how manuals have been produced for 2 badly degraded areas in southern Australia (Mount Lofty Ranges, South Australia; and western Victoria) and promotes the methodologies for other regions. Descriptive soil information is pictorially integrated along toposequences and applied to identify key soil features. Complex scientific processes and terminology are more simply communicated to local groups using coloured cross-sectional diagrams and photographs of soil and vegetation to overcome some of the perceived barriers to adoption of best management practices. We consider the approach should have generic application.

Planting Materials

Private and government nurseries in the Philippines are not delivering high quality planting materials of a wide species base for smallholder forestry, tree farming and reforestation programs in the country. A project supported by the Australian Centre for International Agricultural Research (ACIAR) has been conducted to improve the operational effectiveness of the forest nursery sector in the Philippines. Surveys involving personal interviews of nursery operators, observations of the nursery design and facilities and assessment of seedling quality have been undertaken in Leyte (reported in this paper) and in Mindanao to provide baseline information for designing possible interventions. The Leyte study revealed that the low operational effectiveness of forest nurseries is a result of a combination of social, economic, technical and political factors. The majority of private nurseries are managed by resourceconstrained smallholders with little access to high quality seedling production technologies. Seedling production, both in private and government nurseries, is largely quantity-oriented and the pathway of high quality germplasm is not well developed. Government nurseries operate to provide free seedlings but this scheme results in crowding out the small-scale private nurseries, reducing the operational effectiveness of the private nursery sector. It appears that improving the operational effectiveness of the forest nursery sector in the Philippines requires policy changes to re-organize the operation of private and government nurseries and to strengthen the implementation of existing policies regulating the quality of planting stock from the forest nursery sector.

AbstractForest tree seedling production technologies impact reforestation success determined with survival and quality of seedlings. Five Abies alba seedling production technologies were tested: (1) bare-root seedling, three years in the open (3/0); (2) bare-root seedling, two years under a shading net (40% of full light), a year in the open (2/g); (3) ball root seedling, two years under a shading net (40%), a year in the open (2/K); (4) bare-root seedling grown in an opening in a Norway spruce stand (3/Pic); (5) bare-root seedling, three years under Scots pine canopy (3/Pin). Silver fir seedlings acclimatized their growth rates to the common growing environment in relation to the seedling production technology used in the nurseries. The height and diameter at root collar were positively correlated with survival. The 3/Pic seedlings manifested the lowest survival and were lower than other seedlings in terms of height and photochemical efficiency. The needle photochemistry of seedlings growing two years in plantation was determined by their earlier acclimation to the nursery light conditions. The production technology determined the ability of A. alba seedlings to acclimatize to the natural environment. Ball root seedlings grown two years in shade and a year in the open (2/K) acclimatized better to the full light environment compared with bare-root seedlings produced in canopy shade, and they are likely more suitable to be planted after clearcutting.
