Spain is one of the Mediterranean countries most severely affected by wildfires during the last 30 years, despite enhanced fire suppression efforts. At present, forest area is increasing more in Spain than in any other European country, and also has one of the highest densities of fire ignitions. However, forest management plans have been developed for only 13% of Spanish forest areas. The objective of the present study was to assess the role of forest fuel management for wildfire prevention in Spain. Different fuel management techniques, including mechanical treatments, prescribed burning and controlled grazing, were considered. A quantitative SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis was performed, based on a thorough documentation review and on the opinions of forest fire experts. Results enabled the identification of obstacles that hinder the implementation of effective fuel management, and suggested strategic recommendations to overcome them. New opportunities related to rural development activities (e.g. promotion of ‘FIRESMART’ products) would be highly relevant in fire-prone forest areas. These opportunities should provide additional funding for sustainable forest management and could foster fuel management activities that would directly involve and benefit rural populations.

Main Attribute

In the Amazon many forest species present problems of identification and obtaining botanical material with reproductive structures is not always possible. The macro and microscopic characteristics of the wood of three species of the genus Tachigali Aubl were analyzed in order to determine basic differences among the species. The collection of material was carried at the Forest Management Unit III, in the Flona do Jamari (Jamari National Forest), where we selected arboreal individuals from the species Tachigali poeppigiana Tul., Tachigali setifera (Ducke) Zarucchi & Herend and Tachigali subvelutina (Benth.) Oliveira-Filho, commonly known in Brazil as Tachi Preto (Black Tachi), Tachi Vermelho (Red Tachi) and Tachi Amarelo (Yellow Tachi), respectively, in which the coloring of the core is the main attribute for assigning their vernacular name. Heartwood samples were collected for the making of the specimens. The axial parenchyma was vasicentric and unilateral for T. poeppigiana and T. setifera, and unilateral and sparse for T. subvelutina. Pores were classified as medium and large for T. setifera and T. poeppigiana and very uncommon for T. subvelutina; however, they are medium and very uncommon for the three species. All species showed uniseriate, non-stratified and homogeneous rays. We concluded there are anatomical characteristics that allow the differentiation of the species from the genus Tachigali, which may be used to assist in forest management plans, as well as the surveillance system.

Matlab Programming

In Turkey, forest management plans are produced by terrestrial surveying techniques for 10 or 20 year periods, which can be considered quite long to maintain the sustainability of forests. For a successful forest management plan, it is necessary to collect accurate information about the stand parameters and store them in dynamic and robust databases. The position, number, height and closure of trees are among the most important stand parameters required for a forest management plan. Determining the position of each single tree is challenging in such an area consisting of too many interlocking trees. Hence, in this study, an object-based tree detection methodology has been developed in MATLAB programming language to determine the position of each tree top in a highly closed area. The developed algorithm uses the Canopy Height Model (CHM), which is computed from the Digital Terrain Model (DTM) and Digital Surface Model (DSM) generated by using the point cloud extracted from the images taken from a UAS (Unmanned Aerial System). The heights of trees have been determined by using the CHM. The closure of the trees has been determined with the written MATLAB script. The results show that the developed tree detection methodology detected more than 70% of the trees successfully. It can also be concluded that the stand parameters may be determined by using the UAS-based point clouds depending on the characteristics of the study area. In addition, determination of the stand parameters by using point clouds reduces the time needed to produce forest management plans.

Abstract Fuel reduction treatments implemented by nonindustrial private forest (NIPF) landowners affect wildfire hazard potential on both their tracts and surrounding lands. However, it is not clear how concerned they are about wildfire damages and what actions they are willing to take to lower wildfire hazard. This study determined the landowner concern level about wildfire damages and identified factors affecting their concern and fuel treatment implementation using seemingly unrelated and binary probit models, respectively. Approximately, 68% of landowners were concerned about property damage due to wildfires, and 45% implemented some fuel reduction treatments. The most common and least costly fuel treatment was prescribed burning ($18/acre) followed by chemical ($59/acre) and mechanical ($127/acre) treatments. Raising awareness about potential monetary losses due to wildfires, assisting landowners in preparing written forest management plans, and prioritizing areas with predominant pine cover will encourage landowner participation in hazardous fuel reduction programs and facilitate more effective wildfire mitigation. Study Implications Nonindustrial private forest (NIPF) landowners were concerned about monetary damages due to wildfires, which influenced their implementation of fuel reduction treatments. Estimates of fuel treatment cost and implementation frequency provide baseline information necessary to determine cost-effectiveness of various fuel treatments for their subsequent prioritization. Programs and policies that increase awareness among landowners about potential monetary losses due to wildfires, facilitate preparation of forest management plans with wildfire hazard mitigation prescriptions, and prioritize areas with high wildfire hazard potential are needed to increase implementation of hazardous fuel reduction treatments by NIPF landowners to reduce wildfire intensity and severity.

Decision Making Units

In this study, we develop a marginal chance-constrained data envelopment analysis (DEA) model in the presence of nondiscretionary inputs and hybrid outputs for the first time. We call it a stochastic nondiscretionary DEA model (SND-DEA), and it is developed to measure and compare the relative efficiency of forest management units under different environmental management systems. Furthermore, we apply an output-oriented DEA technology to both deterministic and stochastic scenarios. The required data are collected from 24 forest management plans (as decision-making units) and included four inputs and an equal amount of outputs. The findings of this practical research show that the modified SND-DEA model in different probability levels gives us apparently different results compared with the output from pure deterministic models. However, when we calculate the correlation measures, the probability levels give us a strong positive correlation between stochastic and deterministic models. Therefore, approximately 40% of the forest management plans based on the applied SND-DEA model should substantially increase their average efficiency score. As the major conclusion, our developed SND-DEA model is a suitable improvement over previous developed models to discriminate the efficiency and (or) inefficiency of decision-making units to hedge against risk and uncertainty in this type of forest management problem.

Planning Processes

Conceptions and challenges of public participation in British Columbia are reviewed to identify those characteristicsof planning processes that serve to benefit or constrain the interests and needs of public stakeholders. Perspectives onpublic participation, including representative and participatory democracies, and approaches to incorporating publicperspectives in decision-making (i.e., shared decision-making, consensus-building, and interest-based negotiation) arepresented to demonstrate the different approaches (and their benefits and challenges) available for providing opportunitiesfor public participation. Lessons from other natural resource management contexts are distilled and used to evaluatethe BC context. Three principal forest planning and management frameworks (the Commission on Resources and theEnvironment, Land and Resource Management Plans, and sustainable forest management certification) are examinedin light of whether meaningful opportunities for public participation were provided.Key words: public participation, British Columbia, Commission on Resources and the Environment, Land and ResourceManagement Plans, sustainable forest management certification
