Growth modelling component of the AFFFM
No full textWhen developing the AFFFM, a conscious decision was made at an early stage to populate the model with as much data as possible. By doing so it was felt that the model would be more useful to a wider range of users. A module was developed which contains information about potential growth rates, harvest ages and log prices for a number of suitable timber species for the Atherton Tableland, the Darling Downs and the New England Tableland regions of eastern Australia. Data on the potential growth rate, harvest age and product mixtures for tree species suitable for plantations on the New England Tablelands and Darling Downs were generated using the Plantgro program. Users of the model from these areas can choose to load the appropriate values for the various species by specifying the location and soil type of the planned plantation. Data on the potential growth rate, harvest age and timber price for 31 species of cabinet timbers in Far North Queensland were also included. These data were obtained from a previous survey of forestry experts undertaken by Herbohn et al. (1999). This chapter outlines the process through which growth data used in the AFFFM were collected

Reforestation progress and forestry incentive schemes in Australia
No full text[Extract] This chapter examines the economic, political and social factors that have influenced small-scale forestry policy within Australia, as a background to discussion of the initiatives that have been developed and the forces driving forestry policy. A variety of initiatives to support small-scale forestry have been introduced in Australia in the last two decades. These have sometimes pursued competing objectives of commercial returns from timber and achievement of an array of environmental benefits arising from plantation forestry. Individual programs tend to have had a short life before being replaced by new initiatives, though in recent years there has been growing reliance on joint venture schemes
New horizons in sustainable small-scale foresting
No full textPreceding chapters have illustrated the multitude of objectives and wide variety of forms which small-scale forestry can take. We now seek to draw together some of the themes developed. Impediments to small-scale forestry are examined, and forest policies for achieving maximum benefits are discussed. Small-scale forestry is viewed as not simply a scaled-down version of industrial forestry, but a vibrant industry sector with great diversity in forestry systems and objectives. Notable developments and innovations are taking place in small-scale forestry
The role of small-scale forestry throughout the world
No full text[Extract] This chapter presents a perspective on the importance of small-scale forestry in developed and developing countries. The diversity of production systems in small-scale forestry is discussed and sustainability issues examined. The rationale and layout of this book is then outlined
Assessing financial performance of small-scale forestry
No full text[Extract] This chapter discusses some of the key issues associated with assessment of the financial performance of small-scale plantations. Issues discussed include choice of financial performance indicators, modelling of tree growth for nontraditional species, and price and marketing considerations. The development of financial models for small-scale mixed-species plantations established under the Community Rainforest Reforestation Program (CRRP) in north Queensland provides a case study of how models may be developed when there is a lack of empirical data
Using Financial Analysis Techniques in Forestry Research
No full textPrevious modules introduced the principles and methods of Discounted Cash Flow (DCF) and Cost Benefit Analysis (CBA) in relation to forestry projects. The current module extends the discussion of DCF to include its use in financial analyses. The purpose of CBA is to determine whether investment projects (used in the widest sense) are worthwhile from a social perspective, taking into account all costs and benefits including positive and negative externalities. In contrast, the focal point of financial analysis is assessing the impact of the project of the wealth of the individual or firm considering the project. In this module, concepts and methods of financial analysis (FA) will be introduced, and then applied to a case study of financial evaluation of a forestry project
Reliability of the Barangay-based smallholder tree farm inventory: Research and policy implications
No full textThe reliability of the inventories of smallholder tree farms conducted by barangay chairmen in selected municipalities in Leyte has been evaluated. The average number of trees per farm reported in the barangay-based inventory is 40 while the average verified number of trees is 49. The average stand age reported is 9.25 while the verified stand age is 9.03. No significant difference was found between the barangay-based inventory and verified data in terms of number of trees and stand age. Regression analysis shows that the difference in number of trees reported and the verified number of trees is directly proportional to the aggregate number of trees grown, thus the more trees grown, the higher the difference. The species reported by barangay-chairmen were found to be correct although some of them were reported using local names. The response rate of barangay chairmen in conducting the barangay-based inventory was acceptably high
