Forest management plans in a tangle

Sustainable Forest Management in Cameroon Needs More than Approved Forest Management Plans

One of the main objectives of the 1994 Cameroonian forestry law is to improve the management of production forests by including minimum safeguards for sustainability into compulsory forest management plans. As of 2007, about 3.5 million hectares (60%) of the productive forests are harvested following the prescriptions of 49 approved management plans. The development and implementation of these ...

Performance evaluation of forest management plans (Case study: Iranian Caspian forests)

The aim of this research was to measure the relative efficiency of forest management plans in north of Iran. In order to fulfill the research, data of 12 forest management plans were collected from the financial balance sheets of Shafaroud Forest Company during a ten years period. First of all, basic Data Envelopment Analysis (DEA) models (BCC and CCR) were used to determine the efficiency. The...

Desmosomes in a tangle

Desmosomes in a tangle ntermediate filament–associated desmosomes—like their actin-associated counterparts, adherens junctions—link neighboring epithelial cells through cadherin connections. Crystal structure analyses of adherens junction cadherins suggested that these proteins interact at their NH 2 -terminal tips. A recent model shows that the most distal of five extracellular domains, called...

Using a GIS model to assess terrestrial salamander response to alternative forest management plans.

A GIS model predicting the spatial distribution of terrestrial salamander abundance based on topography and forest age was developed using parameters derived from the literature. The model was tested by sampling salamander abundance across the full range of site conditions used in the model. A regression of the predictions of our GIS model against these sample data showed that the model has a m...
