We explore the factors influencing the abundance of Colobus vellerosus in 11 forest fragments [Boabeng-Fiema Monkey Sanctuary and 9 surrounding forest fragments (range: 3.2-190 ha)] in the forest-savanna transition zone of Ghana. We used a 'complete' count for the colobus census in the fragments. We determined the fragment sizes using geographic information system methods and assessed forest fr...

Stand boundary identification is an important factor in forest management planning that is dependent on the quality and resolution of the imagery available. We identified stand boundaries on an area within the John C. Stennis Space Center using two sources of multispectral imagery, IKONOS and QuickBird. Forest stands were delineated using eCognition v3.0. Segmentation was performed by initially...

The boreal forest biome occupies 13 x I06km1. It comprises approximately 25% of the world's forest land (Olson et al. 1983; Apps et al. 1993) and includes 2.6 x 106km1 of peatlands (Gorham 1991). Changes in the extent or functioning of the boreal forest wuld substantially modify global climate through (1) release of its large stocks of soil carbon (Post et al. Boreal forests have also been impl...

The management of second growth forests to accelerate the restoration of late-successional and old growth characteristics will be one of the greatest challenges for conservation in the redwood region over the next century. In the redwood region, the largest complex of protected areas exists in the north, however >50 percent of these forest reserves are composed of logged, degraded second growth...

Extreme and persistent reductions in annual precipitation and an increase in the mean diurnal temperature range have resulted in patch scale forest mortality following the summer of 2010–2011 within the Forest study area near Perth, Western Australia. The impacts of 20 bioclimatic indicators derived from temperature, precipitation and of actual and potential evapotranspiration are quantified. W...

today, determination of the ecological species groups for current and future situation of forest and its relationship with environmental factors is necessary for forest management. for this purpose, 50 plots were established in altitude range of 2091- 2811 meters above sea level and 600 hectare in protected area of western dena. four ecological groups was identified using twinspan analysis that...

The regional determining factors underlying inter- and intra-site variation of (15)N natural abundance in foliage, O horizon and mineral soil were investigated in eastern China.(15)N natural abundance values for these forest ecosystems were in the middle of the range of values previously found for global forest ecosystems. In contrast to commonly reported global patterns, temperate forest ecosy...

according to reports of forest range and watershed management organization of iran, hundreds of forest fires take place in our country every year. due to destroying forest and grass land in different parts of iran, especially in zagross and alborz mountain, it is necessary to develop new methods to reduce fire effects in these places. there are many parameters that increase probability of fire ...

This paper looks at the economics of conversion and fragmentation of forest land. The forestry economics literature has generally focussed on the management of a single stand for timber and non-timber forest benefits with little attention being paid to forest level land use decisions, and in particular forest stand interactions. As noted by Bowes and Krutilla (1989), the focus on a single stand...

During recent years, oak decline has been widely spread across Brant’s oak (Quercus Brantii Lindl.) stands in the Zagros Mountains, Western Iran, which caused large-area forest dieback in several sites. Mapping the intensity and spatial distribution of forest dieback is essential for developing management and control strategies. This study evaluated a range of geostatistical and interpolation m...
