Wildlife fauna, in general term, consist in every animal specie that subsist, subject to natural selection, and develops in total freedom (LGEEPA, 2018). This represents a vital resource for humankind, in every possible way, either as a source of nutriments, for those species suitable for consumption; cultural, as in the case of those animals that hold an especial relation with the nation, either as symbol of identity or as elements of local folklore, traditions and believes; in addition to their ecological importance, which tends to be the most overrated, since each specie has a role in the ecologic dynamic.
Since the instauration of any project requires the transformation of the site, full or partial; several modifications take place, such as the removal of flora along with alterations of the edaphic structure, in consequence other factor will be affected, like the animal population who use this site as refugee or food sources. As it was stated before, part of the wildlife significance is the ecologic component, any alteration to the fauna could originate changes in the structure of the ecological net and further damages in the ecosystem (Schhuelze, Monney, 1994). A famous example of this kind of incidents, is the Yellowstone Park wolves case, where the reintroduction of the grey wolf (Canis lupus), after a prolonged absence, modified the presence of several species, even the landscape and vegetation changed (Smith, et al, 2003). Every organism bares an importance in the balance and wellbeing of the site and surrounding area, that’s why animal communities must be taken into consideration as relevant factors for the decision making.
Throughout any project in undeveloped landscapes, regardless of the degree of disturbance, is essential to perform the proper studies to identify the existence, characteristic and status of the wildlife; with the aim of keeping a steady knowledge of the fauna diversity along with their interaction with the surrounding biotic and abiotic elements. The information gathered by these studies, is going to be extremely useful for building up tools and instruments for future protection and conservation of the wildlife. To prevent or minimize the possible impacts and contribute to the care and maintenance of wildlife and healthy ecosystems.
