New methods for evaluating structural properties of stands and individual tree mortality within forests are needed to enhance biodiversity assessment in forest inventories. One approach is to assess the degree of naturalness in a forest. We assessed forest naturalness by examining patterns and causes of mortality and deadwood amount and spatial distribution as indicators of naturalness, or degr...

Dr. Engineers, ICONA (Instituto National para la Conservacion de la Naturaleza), Madrid, Spain. Abstract: Management of the fragile and greatly modified ecosystems in the Spanish Mediterranean climate is complex. Rainfall occurs in a few intensive storms on rough topography. Climax vegetation is sparse forest dominated by evergreen xerophilic species. The emphases of the National Institute for ...

This study investigates how federal, state, and private corporate forest owners in a fire-prone landscape of southcentral Oregon manage their forests to reduce wildfire hazard and loss to high-severity wildfire. We evaluate the implications of our findings for concepts of social–ecological resilience. Using interview data, we found a high degree of "response diversity" (variation in forest mana...

Forest fire-potential is natural disaster that breaks out strongly , destructs largely and is difficult to dispose and rescue, its destructive power has a serious threat to the security of society and human living environment, moreover, it does greatly damage to natural ecological environment. Therefore, the study on forest fire prediction and prevention is a main job. In fact, it is complicate...

Forest disturbance often results in changes in soil properties and microbial communities. In the present study, we characterized a soil bacterial community subjected to disturbance using 16S rRNA gene clone libraries. The community was from a disturbed broad-leaved, low mountain forest ecosystem at Huoshaoliao (HSL) located in northern Taiwan. This locality receives more than 4,000 mm annual pr...

FOREST-BASED ALGORITHMS IN NATURAL LANGUAGE PROCESSING Liang Huang Supervisors: Aravind K. Joshi and Kevin Knight Many problems in Natural Language Processing (NLP) involves an efficient search for the best derivation over (exponentially) many candidates. For example, a parser aims to find the best syntactic tree for a given sentence among all derivations under a grammar, and a machine translat...

The sustainable management of forest resources can only be achieved through a well-organized road network designed with the optimal spatial planning and the minimum environmental impacts. This paper describes the spatial layout mapping for the optimal forest road network and the environmental impacts evaluation that are caused to the natural environment based on the multicriteria evaluation (MC...

In the springs of 2000, the Forest Engineering Research Institute of Canada (FERIC) undertook a series of studies to investigate the potential of using a combination of technologies to extend log hauling operations during the traditional spring break-up period. During spring break-up, thin pavement roads are weakened, resulting in the application of government-imposed load restrictions to preve...

Structural transformation in the economy and institutional innovations bring changes in the socio--economic dynamics in the society. This leads to changes in the pattern of income distribution, poverty and income inequality. Environmental resources such as forest still make significant contribution in rural household economy. The leasehold forestry program for the poor introduced in the last de...

Concreteness and imageability have long been held to play an important role in the meanings of figurative expressions. Recent work has implemented this idea in order to detect metaphors in natural language discourse. Yet, a relatively unexplored dimension of metaphor is the role of affective meanings. In this paper, we will show how combining concreteness, imageability and sentiment scores, as ...
