New methods of forest management and the study of their impact on sustainability are strongly dependent on realistic mathematical modelling. The complexity of the models however, makes the use of computational power, and thus the incorporation of knowledge from computer science and research, indispensable. In this paper we wish to demonstrate the development of a simulator for the growth and production of cork oak woodlands – montados. The software is divided into three sub-modules, sharing a common core, with functions and mathematical operations. The desktop client allows for repeated operations for more intense calculations, and statistical operations for modelling purposes. The web version is intended to be used by final users in forest practice. It permits simulation of inventory data based on individual tree measurements, and inventory data based on plot description with a reduced amount of detail (number of trees per ha, diameter structure, etc.) The last module allows the incorporation of the cork model into other software by means of SOAP protocol, via web services. It conforms to the WS-I Basic Profile 1.1, to ensure interoperability among the largest number of clients. This module allows other developers to use the cork oak growth-model in their software...

Forest and fire management planning activities are carried out mostly independently of each other. This paper discusses research aiming at the development of methods and tools that can be used for enhanced integration of forest and fire management planning activities. Specifically, fire damage models were developed for Eucalyptus globulus Labill stands in Portugal. Models are based on easily measurable forest characteristics so that forest managers may predict post-fire mortality based on forest structure. For this purpose, biometric data and fire-damage descriptors from 2005/2006 National Forest Inventory plots and other sample plots within 2006, 2007 and 2008 fire areas were used. A three-step modelling strategy based on logistic regression methods was used. In the first step, a model was developed to predict whether mortality occurs after a wildfire in a eucalypt stand. In the second step the degree of damage caused by wildfires in stands where mortality occurs is quantified (i.e. percentage of mortality). In the third step this mortality is distributed among trees. Data from over 85 plots and 1648 trees were used for modeling purposes. The damage models show that relative damage increases with stand basal area. Tree level mortality models indicate that trees with high diameters...

In Portugal over 85% of the forest area is occupied by Maritime pine (Pinus pinaster), eucalypt (Eucalyptus globulus), cork oak (Quercus suber) and holm oak (Quer- cus ilex). Eucalypt plantations extend over 20% of the total forest area being the main source of raw material for the pulp and paper industry. In The main aim of the present study was to develop a planning oriented stand level model to pre- dict wildfire risk for a wide range of forest stands in Por- tugal, including different mixtures of species as well as even-and uneven-aged structures. The model aims at predicting the effects of management options (e.g. silvi- cultural treatments) on the probability of wildfire propa- gation to enhance the integration of forest and fire management activities.

Although tree hollows seem to be key structures for a wide range of forest mammals, their importance for Mediterranean forest carnivores remain poorly understood. Here we address this issue, by analysing daily resting site use by 21 radio-collared common genets. Tree hollows were used far more frequently during the wet season (October–April; 73.1% of daily locations) than in the dry season (May–September; 47.6%). Nests and underground dens were the second and third most frequently used resting sites, respectively, in both wet (17.5% and 9.4%) and dry (34.1% and 18.3%) seasons. Each individual reused a large percentage of its resting sites (65.7%). Some resting sites (17.3%) were used by more than one individual, but simultaneous sharing was exceedingly rare (0.56% of daily locations). Hollow use probability during the wet season varied little in relation to environmental variables, though there was a tendency to be higher away from riparian habitats (>50 m) and to be lower in sites with very high shrub cover (>80%). Environmental influences were responsible for more variability in the dry season, when hollow usage was highest in hot days, in days with precipitation, far from riparian habitats, close to sources of human disturbance...

Report of Cost Action FP 0804 Forest Management Decision Support Systems (FORSYS); Computer-based tools for supporting forest management. The experience and the expertise world-wide answers a call from both the research and the professional communities for a synthesis of current knowledge about the use of computerized tools in forest management planning. According to the aims of the Forest Management Decision Support Systems (FORSYS) (http://fp0804.emu.ee/) this synthesis is a critical success factor to develop a comprehensive quality reference for forest management decision support systems. The emphasis of the book is on identifying and assessing the support provided by computerized tools to enhance forest management planning in real-world contexts. The book thus identifies the management planning problems that prevail world-wide to discuss the architecture and the components of the tools used to address them. Of importance is the report of architecture approaches, models and methods, knowledge management and participatory planning techniques used to address specific management planning problems. We think that this synthesis may provide effective support to research and outreach activities that focus on the development of forest management decision support systems. It may contribute further to support forest managers when defining the requirements for a tool that best meets their needs. The first chapter of the book provides an introduction to the use of decision support systems in the forest sector and lays out the FORSYS framework for reporting the experience and expertise acquired in each country. Emphasis is on the FORSYS ontology to facilitate the sharing of experiences needed to characterize and evaluate the use of computerized tools when addressing forest management planning problems. The twenty six country reports share a structure designed to underline a problem-centric focus. Specifically...

The urgent need to limit anthropogenic carbon emissions has led to a global initiative to Reduce Emissions from Deforestation and forest Degradation (REDD+). But designing national architectures for REDD+ that integrate local actions on forests with national-level outcomes and do so effectively, efficiently, and equitably continues to be challenging. One option to facilitate the design and implementation of REDD+ is to learn from the experience of other programs that have historically been successful in achieving sustainable tropical forest management, such as community forest management (CFM). Lessons about the factors that contribute to CFM success will be useful in designing REDD+ programs. REDD+ may also benefit from harnessing the capital developed by CFM. Of course, REDD+ and CFM represent both opportunities and challenges for each other. Identifying how CFM can contribute to REDD+ goals, and the potential benefits and risks in using CFM to achieve REDD+ implementation requires careful analysis of available evidence because the two sets of interventions do not have a complete overlap in terms of their objectives and mechanisms.

This policy note was prepared in response to a request from the Government of Southern Sudan (GoSS) for World Bank assistance in developing legislative and institutional policies and strategies that will take advantage of the potential of the region's forest resources to contribute to poverty alleviation, food security, sustainable agriculture, economic growth, and to protection of forest-related environmental services such as climate, biodiversity, water, and wildlife resources. The note is intended to: (a) take stock of the current situation on the ground, including identifying the legislative, institutional, governance, and policy reforms needed to create an enabling environment for both public and private-sector investment. This should help in contributing to improved understanding of the currently underutilized potential of Southern Sudan's forest resources; (b) analyze what has worked and what has not worked prior to and since the signing of the Comprehensive Peace Agreement (CPA); and (c) suggest priority solutions and actions towards revitalizing the forestry sector. Key policy issues addressed in this note include: 1) strengthening forest resource information and knowledge base; 2) developing a coherent legislative and policy framework...

A pattern of forest area loss followed by a period of reforestation is representative of the forest transition process. Forest transition has been observed in many countries and is a feature of the development process. China reached its inflection point earlier and faster than most other countries that have gone through the transition. The report describes the success of reforms to forest resource tenure in collective forest areas. These reforms, which collectively amount to the largest transfer of forest assets in history, have effectively extended forest ownership to a million, mostly poor, rural households. These reforms have increased forest-based incomes, have increased timber harvests, and have done so sustainably by virtue of increasing planting and forest management and resource protection effort. The World Bank work in China's forestry sector has been successful. However, the developments discussed in this report raise new opportunities and challenges. It is no longer clear, for example, that World Bank loans are especially important in relation to the financing of commercial plantations. While the Bank has begun to move its plantation financing to public goods...

A major ice storm in January 1998 provided an opportunity to study the effects of a rare, intense disturbance on the structure of the northern hardwood forest canopy. Canopy damage was assessed using visual damage classes within watersheds of different ages at the Hubbard Brook Experimental Forest (HBEF) and changes in leaf area index in two of these watersheds. Ice thickness was measured, and ice loads of trees were estimated using regression equations. In the 60- to 120-year-old forests (mean basal area 26 m2•ha–1), damage was greatest in trees >30 cm diameter at breast height and at elevations above 600 m. Of the dominant tree species, beech (Fagus grandifolia Ehrh.) was the most damaged, sugar maple (Acer saccharum Marsh.) was the most resistant, and yellow birch (Betula alleghaniensis Britt.) was intermediate. Trees with advanced beech bark disease experienced heavier ice damage. Little damage occurred in the 14-year-old forest, while the 24- to 28-year-old forest experienced intense damage. In the young stands of this forest, damage was greatest between 600 and 750 m, in trees on steep slopes and near streams, and among pin cherry (Prunus pensylvanica L.). Recovery of the canopy was tracked over three growing seasons, and root growth was monitored 1 year after the storm. Because of the high density of advance regeneration from beech bark disease and root sprouting potential in ice-damaged beech...

Because of the importance of salamanders in forest food chains, the effects of forest management practices on populations of these animals warrant consideration. We compared the numbers and activity patterns of salamanders in areas of a deciduous forest in central New York State that had been cut selectively for firewood, or clearcut, or planted with conifers. Numbers of salamanders were lower in three recently distrurbed habitats than in adjacent old-growth control stands. The frequency of above-ground activity by both species of salamanders was positively correlated with the density of understory vegetation and the depth of leaf litter. Small-scale habitat disruption associated with harvesting firewood increased the numbers of the terrestrial eft stage of the red-spotted newt (Notophthalmus viridescens) but had no effect on numbers of red-backed salamanders (Plethodon cinereus). A recently clearcut area had fewer red-backed salamanders than adjacent old-growth forest had, but the numbers of salamanders in a 60-year-old second-growth forest were indistinguishable from those in the adjacent old-growth forest. Populations of salamanders in a conifer plantation were low. Thus, salamanders seem to be resilient to limited disturbance of forests...

AbstractThe aim of this study was to assess the influence of meteorological conditions on the fire occurrences in forest stands of Lichinga district, in the period from 2010 to 2012. Data about fire occurrences records of the district of Lichinga and two others close districts (Lago and Sanga) were provided by the Center for Monitoring and Control of Forest Fires (CCMIF) of the company Chikweti. Daily weather data: temperature, rainfall and relative humidity of the same period, recorded at 13:00 PM, by the meteorological station of the Institute of Agronomic Research of Mozambique (IIAM) in Lichinga district were also provided to this work. Meteorological data were submitted to regression analysis and Tukey test. The results showed a significant variation in temperature and humidity on both tests. The overlapping of fire occurrences and meteorological variables, suggested a great influence of the meteorological conditions in the occurrence of fires, mainly due to the very long dry periods. In 2010 there was a delay in the occurrence of fires; this was related to the rainy season which was slightly longer. September and October was the months that recorded the highest number of fire occurrences throughout the studied period.ResumoInfluência das condições meteorológicas na ocorrência dos incêndios florestais no distrito de Lichinga...
