Land use planning with multiobjective programming: a model for forest development in the hills of Nepal
… term planning of renewable natural resources development in the Hills of Nepal. Considerable emphasis was placed upon identifying land use planning problems for the prevalent limited market economy and subsistence farming system. A multiobjective programming model was chosen for modeling the …

Forest resource management for sustainable development : a case of Mount Meru Forest Reserve in Northern Tanzania
… as applied to most of the world's tropical forests are anthropocentric. In view of this, conservation of these ecosystems has been threatened by overuse and pressure of exotic monocultures. Sustainable forest development aims at utilizing the forest resource without unduly degrading the …

The relationships between forest and mountain fynbos communities in the southwestern Cape Province of South Africa
Evergreen forests are believed to be restricted to moist sites in the southwestern Cape because of seasonal drought and high fire frequency in adjacent fynbos shrublands. However, soil moisture has not been demonstrated as the controlling factor. Succession to forest has been observed in some areas …

Spatial and temporal dynamics of fire and vegetation change in Thunder Creek watershed, North Cascades National Park, Washington
… Cascades National Park to evaluate past fire and forest vegetation dynamics. The first study evaluated forest development following a series of fires c. 150 years ago. Tree species, age and size data were sampled along altitudinal transects. Tree species distributions and relationships with …

Flood Processes, Forest Dynamics, and Disturbance In the Congaree River Floodplain, South Carolina
… impacts. This study was designed to examine the forest development dynamics in abandoned meander landforms on the Congaree River floodplain, South Carolina in order to gain a better understanding of the forest successional responses to environmental gradients and historic logging …

Where can we grow kelp? Evaluating data for the selection of N. luetkeana seaforestation and aquaculture sites in British Columbia nearshore waters
… prior to establishing locations suitable for seaforestation — a regenerative practice that aims to grow resilient marine ecosystems. Sections of the British Columbian (BC) coastline were examined to identify favourable conditions for Nereocystis luetkeana forest development based on available …

Environmental determinism and forest structure and composition: a naturally replicated experiment
Ecological theory states that forest succession is largely environmentally determined. Many investigators have suggested, however, that stochastic processes can frequently alter successional pathways. In particular, the colonization phase is thought to be very stochastic. This study utilizes a …

Woody Species Diversity, Forest and Site Productivity, Stumpage Value, and Carbon Sequestration of Forests on Mined Lands Reclaimed Prior to the Passage of the Surface Mining Control and Reclamation Act of 1977
The present state of forestry post mining land uses has prompted concern among researchers, landowners, and the public. Surface mines reclaimed to forests under the provision of the Surface Mining Control and Reclamation Act (SMCRA) may not achieve site productivity levels required by the law. …

Aboriginal forest tenure and governance in British Columbia : exploring alternatives from a Stellat'en First Nation community perspective
… contribute to the identification of appropriate forest tenure and governance designs that are in congruence with Aboriginal values, interests and rights. The research is highly relevant to current societal deliberations on sustainable forest management as well as to the future of the forest …

Holocene variations in summer temperature and effective moisture: Understanding the causes of vegetational dynamics in Alaska
… on soil carbon pools. However, responses of the forest—tundra ecotone to the modern warming trend are spatially heterogeneous because controls other than temperature limit tree growth and seedling establishment near tree line. Paleo-investigations can address the sensitivity of the forest—tundra …

Carbon Pools and Fluxes as an Indicator of Riparian Restoration
Riparian forests are integral components of the landscape. The inherent biogeochemical processes that occur in such forests provide numerous benefits to wildlife and society. Maintaining good water quality is a major benefit from riparian forests and therefore, the maintenance, creation, or …

Biogeochemistry of Carbon on Disturbed Forest Landscapes
Carbon accreditation of forest development projects is essential for sequestering atmospheric CO2 under the provisions of the Kyoto Protocol. The carbon sequestration potential of surface coal-mined lands is not well known. The purpose of this work was to determine how to measure carbon …

Climate change adaptation and sustainable forest management in the boreal forest
Climate change will pose increasing challenges to forest managers working to achieve sustainable forest management in the boreal forest. A logical starting point for climate change adaptation is to proactively identify management practices and policies that have a higher likelihood of achieving …

The effects of tree crown plasticity on the structure and dynamics of near-natural beech forests
A new individual-based forest model for the species beech (Fagus sylvatica L.) was developed and implemented. The model called BEEch Plasticity (BEEP) describes tree crown plasticity phenomenologically and is able to model aboveground competition for PAR on a process basis. The current debate about …

Diversity, Invasibility, and Stability of Appalachian Forests across an Experimental Disturbance Gradient
… I measured how plant communities in Appalachian forests responded to disturbances caused by forest management activities. I had two primary objectives including (1) testing theories of biological diversity and invasions by nonnative species; and (2) providing empirical data that will help guide …

Restoration of threatened species populations: tuatara rehabilitations and re-introductions
… of seabird colonies 3. presence of open canopy forest The threat posed by kiore to established tuatara populations was investigated by determining the existence and degree of food competition before and after an eradication program for kiore on offshore islands. Kiore successfully out-competed …

Long-Term Disturbance Histories Of Managed And Natural Mixed-Hardwood Forests Of Central Indiana
… of the last century, we have observed changes in forest composition and structure related to changes in disturbance regimes. Reduced frequency and severity of disturbance events has allowed for the ingrowth of shade-tolerant, mesophytic species into forest understories; the result is shifting …
