Wildlife conservation evaluation: attributes, criteria and values

Review on Problems, Prospects and Economic Contribution of Wildlife Management and Ecotourism in Ethiopia

“…Although it may be inappropriate to restrict wildlife to a few kinds of organisms common usage, public perceptions, funding allocations, and history have resulted in a practical definition of wildlife as undomesticated free-ranging vertebrates. The definition of wildlife is left as essentially undomesticated, free-ranging terrestrial vertebrates (reptiles, amphibians, birds, and mammals) [13]. These diverse species of wildlife are protected and managed in different conservation areas (Ethiopia Wildlife Conservation Authority [14].…”

The ecodiver index in the evaluation of habitats: a complementary methodology for forest inventory in the elaboration of technical plans and ordinance of land, environmental planning and administration of natural resources

“…It is because of this that taxon or formations of great rarity and fragmentation of distribution area should be evaluated differently in a way that doesn't correspond exclusively to its biogeographic category of distribution area. Once again, the rarity of species (Margules & Usher, 1981;Usher, 1986;Cerrillo et al, 2002) calculated by the inverse number of 10 km x 10 km grids in those where such species appear, it seems the clearest and most exact approach to take. However, due to the lack of data in most of cases, we propose the following more simple scale, although much less precise: dominant plants that create a formation in a fragmented area, with restricted area and rarity.…”

“…and with the use of different techniques (Loidi, 1994). Different methods for the evaluation of ecosystems have been tried and tested by several authors in the recent years (Loidi, 1994;Penas et al, 2005;Díaz González & García-Rodríguez, 1997;Cohen et al, 2005;Behera et al, 2005;Mouw & Alaback, 2003;Usher, 1986;etc.). Generally speaking, the most important aspects that analyse these methodologies include:…”

“…On the other hand it also considers the reduced distribution area or rarity of the species (Margules & Usher, 1981;Usher, 1986;Cerrillo et al, 2002) calculated by the inverse number of 10 km x 10 km grids in which that species appears. Although this last approach is the most exact and correct, the lack of this information for most species means that an approximation is necessary, based upon the size of the biogeographic category.…”

“…The distribution area of a species or syntax influences the level of floral representation in a plant community in characterising a territory and, more indirectly, also in rarity and it could influence the degree of threat or its fragility (Loidi, 1994;Lorite, 2001;Margules & Usher, 1981;Usher, 1986;Cerrillo et al, 2002).…”
