In 1995, the Philippines officially adopted Community-Based Forest Management (CBFM) as its strategy for sustainable forest management in recognition of the urgent need to put “social fences” in open access forests and forest lands. CBFM was conceptualized to partly respond to the issue of the state as being the biggest “absentee landlord” by recognizing de-facto resource management of communit...

We present an in-depth analysis of natural forest management practices in Costa Rica based on a new historical forestry GIS database encompassing five conservation regions in the country where selective logging has been prevalent for the last 18 years. Natural forest management refers to the selective logging practices for the production of timber in natural forest ecosystems. The study conside...

Historical forest landscape dynamics include consideration of spatial and temporal distributions of forest conditions over recent history and also historical disturbance regimes. Understanding of historical landscape dynamics in these senses is relevant to planning future management of federal forest lands on both policy and ecological grounds. Although some particular elements of our policy fr...

Forests in boreal and temperate forest-ecosystems have importance for carbon balance since they sequester large amount of atmospheric carbon by uptake of carbon-dioxide during photosynthesis, and transfer and store carbon in the forest ecosystem. Forest material can be used for bio-fuel purposes and substitute fossil fuels, and supply wood products, which can replace carbon-and-energy-intensive...

Remote sensing and GIS are complementary technologies that, when combined, enable improved monitoring, mapping, and management of forest resources (Franklin 2001). The information that supports forest management is stored primarily in the form of forest inventory databases within a GIS environment. A forest inventory is a survey of the location, composition, and distribution of forest resources...

Forest management has traditionally been considered management of trees for timber. It really includes vegetation management and land management and people management as multiple objectives. As such, forest management is intimately linked with other topics in this volume, most especially those chapters on ecological modelling and human dimensions. The key to responsible forest management is to ...
