At some point in their history, most forests in the Mediterranean Basin have been subjected to intensive management or converted to agriculture land. Knowing how forest plant communities recovered after the abandonment of forest-management or agricultural practices (including livestock grazing) provides a basis for investigating how previous land management have affected plant species diversity...

In the keynote, major reforestation challenges in Scandinavia will be highlighted. The following countries make up Scandinavia: Iceland, Norway, Sweden, Finland and Denmark. For Iceland, with only a forest cover of 2%, a major reforestation challenge is the deforestation and overgrazing in combination with land degradation and extensive soil erosion. The challenges include the conflicts with li...

Twelve ruminally cannulated and six intact crossbred beef steers were used in a randomized complete block design to evaluate the effects of stocking density of a riparian pasture in the Sierra Nevada mountains on grazing behavior, dietary selection, forage intake, digesta kinetics, and growth rates of Carex nebraskensis and Juncus balticus. Nine .5-ha pastures were assigned to one of three trea...

Loss of tropical forests and changes in land-use/land-cover are of growing concern worldwide. Although knowledge exists about the institutional context in which tropical forest loss is embedded, little is known about the role of social institutions in influencing regeneration of tropical forests. In the present study we used Landsat images from southern Madagascar from three different years (19...

This study characterizes the changes in leaf mass, morphological composition and nutritional value of blades palisadegrass (Urochloa brizantha cv. Marandu) under continuous grazing first year implementation pasture after second eucalyptus planting an Integrated Crop-Livestock System Crop-Livestock-Forest, which were tested four seasons. The experimental design was random blocks, with three trea...

Environment[1] Environment[1]Climate Change [2]Forest [3]Mountain [4]Norway [5]Forskning.no [6] Birch forest is currently expanding in mountain regions because of climate warming and reduced grazing pressure. A recent study shows that increased mountain forest promotes climate warming. Tourists and locals have noticed that forests are creeping up hillsides in mountain regions in Norway. Beautif...

Poverty can be defined as a pronounced deprivation of well-being related to lack of material income or consumption, low levels of education and health, vulnerability and exposure to risk, no opportunity to be heard and powerlessness (World Bank 2001:15). Thus, poverty alleviation can be defined as successfully lessening deprivation of well-being. In this regard, forest-based poverty alleviation...

Historically, oak forests and woodlands intergraded with southern boreal forest, temperate mesic forest, and grassland biomes, forming complex fire-mediated relationships in the Great Lakes region of Minnesota, Wisconsin, and Michigan, USA. Variability in fire recurrence intervals allowed oaks to mix with grasses or with mesic forest species in areas with high (2–10 yr) or moderate (several dec...

Pollen analysis of a high altitude bog (Winterton Bog) and an alluvial soil sequence in the upper Awatere catchment on the western flanks of the Inland Kaikoura Range, and radiocarbon dates on wood and charcoal from the Marlborough region, have established a Holocene (post 10 000 years B.P.) vegetation history for this area. The upper slopes of the catchment were almost entirely clad in Podocar...
