Toward sustainable forest management : the potential contribution of timber certification and product labelling in Victoria

Sustainable forest management has emerged as a major international forestry issue. This research assessed the potential contribution of certification and labelling to sustainable forest management in Victoria. The results indicate a potential demand for certified forest products and a consumer willingness to pay to ensure forests are managed sustainably.

A critical review of multi-criteria decision making methods with special reference to forest management and planning

This paper provides a review of research contributions on forest management and planning using multi-criteria decision making (MCDM) based on an exhaustive literature survey. The review primarily focuses on the application aspects  highlighting theoretical underpinnings and controversies. It also examines the nature of the problems addressed and incorporation of risk into forest  management and planning decision making. The MCDM techniques covered in this review belong to several schools of thought. For each technique, a variety of empirical applications including recent studies has been reviewed. More than 60 individual studies were reviewed and classified by the method used, country of origin, number and type of criteria and options evaluated. The review serves as a guide to those interested in how to use a particular MCDM approach. Based on the review, some recent trends and future research directions are also highlighted.

Random forest based lung nodule classification aided by clustering

An automated lung nodule detection system can help spot lung abnormalities in CT lung images. Lung nodule detection can be achieved using template-based, segmentation-based, and classification-based methods. The existing systems that include a classification component in their structures have demonstrated better performances than their counterparts. Ensemble learners combine decisions of multiple classifiers to form an integrated output. To improve the performance of automated lung nodule detection, an ensemble classification aided by clustering (CAC) method is proposed. The method takes advantage of the random forest algorithm and offers a structure for a hybrid random forest based lung nodule classification aided by clustering. Several experiments are carried out involving the proposed method as well as two other existing methods. The parameters of the classifiers are varied to identify the best performing classifiers. The experiments are conducted using lung scans of 32 patients including 5721 images within which nodule locations are marked by expert radiologists. Overall, the best sensitivity of 98.33% and specificity of 97.11% have been recorded for proposed system. Also, a high receiver operating characteristic (ROC) A_z of 0.9786 has been achieved.

Spatial ecology of sooty owls in south-eastern Australian coastal forests : implications for forest management and reserve design

We investigated the home-range size and habitat use of eight Sooty Owls (Tyto tenebricosa tenebricosa) in coastal forests in East Gippsland, Victoria, Australia, between November 2006 and January 2008. The size of home-ranges varied widely; based on 95% adaptive kernel estimates, the average size of home-ranges of males was 3025ha (±1194s.d., n=3), whereas that of females was 994ha (±654s.d., n=5). Sooty Owls utilised a broad range of ecological vegetation classes and topographical features for roosting and foraging at a greater scale than previously assumed. There was minimal selection for habitat types based on floristic composition, primarily only avoiding heathlands (for foraging and roosting) and selecting particular dense foliage (rainforest and riparian scrub) for foliage roosting. Two Owls maintained home-ranges close to logged areas, with logging regrowth (<45 years old) being strongly avoided by both individuals. We recommend that the size of individual reserves for Sooty Owls in commercial forests should be increased to more closely resemble the core spatial resource requirements needed by a pair. Reserves should be largest where they feed predominantly on hollow-dependent prey. Most importantly, rather than conservation measures just focussing on the spatial requirements of Sooty Owls, efforts should be directed towards retaining high densities of crucial resources, such as hollow-bearing trees and mammalian prey species throughout the landscape.

Traditional environmental knowledge and community perceptions in sustaining the forest environment : case study of Minahasa ethnic community in the surrounding of Lake Tondano, North Sulawesi - Indonesia

The idea of sustainable development is distinct from the idea of restoring or conserving nature. This concept is embedded in the Rio Declaration on Environment and Development (1992) which Indonesia and several countries around the world have signed. Sustainable development seeks to interlace humans and nature, while restoration (especially at the large scale) often allows nature to be addressed separately, sometimes out of remorse for the damage caused by humans. In terms of attaining sustainable natural resource development, the opportunities offered by traditional ecological knowledge documentation are considered essential in enabling the achievement of sustainability because most of these Indigenous and/or local communities are situated in areas where many species have been historically cultivated and used in a sustainable way for thousands of years. The skill and techniques of these local communities can provide valuable information for the global community to evaluate current environmental policies. Such research and evaluation is often robustly and best undertaken through ethnoecological methodological paradigms. This paper examines the traditional environment knowledge of the Minahasan ethnic community, who live in the surrounds of Lake Tondano in the North Sulawesi, together with the Minahasan conscious and unconscious actions in conserving their forest ecology in addition to their knowledge of culture about forest protection in the region. In particular, contemporary use of traditional environmental knowledge is examined in terms of its relevance to in traditional resource management and land use planning, as avenues to better curate and manage natural resources through informed regional planning strategies and mechanisms.
