Les savoirs écologiques des chasseurs de gibier d'eau girondins : étude de leur validité pour une gestion de l'avifaune des zones humides.

Abstract

The wildlife management outside the protected natural area asks the question of knowledge of the environments it attends and the evolution of their capacity. Achieve to a detailed description of the qualitative and quantitative distribution of species, with the only professionals as data collectors trained for these purposes, seems Utopian. The immensity of spaces of trivial campaign combined with the mobility of species, which don’t hesitate to use these environments day and night while making long trips, involved a regular presence and a fairly common statement for presence indices when monitoring is necessary. While some researchers and managers are now more reluctant to use the participatory ecology as a way of collecting these data, this method can sometimes suffer from a lack of volunteers. A lack of information can exist on some parts that it would inquire. In this context, consider seeking those who shape these natural environments, staying long and using this nature seems a plausible alternative to acquire information and knowledge necessary to wildlife management. But the quality of these collectors is to ask to measure wealth and reliability, and thus the opportunities or not to engage in monitoring or management process.The wildlife management outside the protected natural area asks the question of knowledge of the environments it attends and the evolution of their capacity.

In this context, consider seeking those who shape these natural environments, staying long and using this nature seems a plausible alternative to acquire information and knowledge necessary to wildlife management. But the quality of these collectors is to ask to measure wealth and reliability, and thus the opportunities or not to engage in follow-ups or management process.The first part of our work first examines the nature of the information necessary for the management of different species of wildlife and variability wherewithal that are used to collect (Chapter 1). The mobilization of knowledge sometimes belonging to rural then raises questions about their scientific relevance (Chapter 2). It appears that these may contribute to better management of wildlife. Thus, in a second part, we show how various hunting practices mobilize knowledge that appear to contribute to the management of wildlife. The characteristics of the night hunting waterfowl make it more conducive to the collection of observations and original knowledge, some of which could contribute to the management of migratory birds. Wetlands Gironde appear as an appropriate field study (Chapter 3). Then, we look in details what constitutes the practice of hunting game, and show that these practitioners are likely to collect original information on birds and wetlands (Chapter 4). The reliability of information collected and therefore the quality of the observers may be heterogeneous according to the affinities of these practitioners, the best of them should be identified. The third part then attaches to detect, using their notebooks, hunters who among the mass of these individuals turn out to be reliable observers (Chapter 5). In addition, the information they are likely to have accumulated combined knowledge. Through a series of interviews and evaluations, it is the nature and the richness of their knowledge that asks to identify the most expert and competent of them (Chapter 6).
