Ecosystem restoration remains high on development agendas worldwide. In the Sahel, including Senegal, knowledge gaps remain how underlying policy and regulations for rights ownership influence farmers’ incentives upscaling land restoration. We contribute to filling these by i) analysing agroforestry related regulations, ii) assessing key stakeholders (foresters, animators, farmers) perceptions ...
THOUGH budding and grafting have been long used by horticulturists a a means of reproducing genetically complex or sterile clones superior for their fruit or ornamental value, little consideration has been given to these techniques by foresters as a means of improving the unit value of forest stands. Forest geneticists in Denmark and Sweden have, however, sensed the practical value of these tec...

Most people are aware of terms used for common groups of animals such as a “pack” of dogs, “school” of fish, “flock” of birds, and “herd” of horses.

To improve street trees through better selection of species 1 and cultivars is an important goal of the Municipal Tree Restoration Program . Communities have been assisted by publishing “Street Tree Factsheets”, through workshops on “Selecting Street Trees’, and by research on performance testing of cultivars. Factsheets on 35 species or genera and 87 cultivars were based on published informati...
INTRODUCTION AND OBJECTIVE Due to the nature of their work, foresters are exposed to many infectious pathogens from the wildlife reservoir. The primary aim of this study was to assess their contact with these pathogens. MATERIAL AND METHODS Sera and antibodies, mainly of IgG class against selected infectious factors, collected from a group of 216 employees of National Forests from eastern and...
" Liberty and forest laws are incompatible, " remarked an English country vicar, speaking on behalf of villagers shut out of woodland reserved for the exclusive use of the king, in 1720. 1 The history of state forestry is indeed a history of social conflict. In monarchies and in democracies, in metropolitan Europe as well as in colonial South Asia, the state management of forests has met bitter...
by foresters, natural fire regimes have been dramatically altered, with concomitant changes in forest composition. Soulé argues that, because we often have no viable concept of natural baseline conditions or normal variability in forest ecosystems, the only viable strategy is to maintain all forest species and natural ecological processes, such as fire. He further asserts that large carnivores ...
