refer the use of strychnine. This poison is often used in horse carcasses, viscera of ruminants
and dogs, and chicken gizzards, thus attracting not only species such as wolves, but also carrion
birds (Brandão, 2004).
National Association for Nature Conservation (Quercus - Associação Nacional de Conservação
da Natureza) is the organisation which supports the project, as been developing a database of all
occurrences recorded since 1992 until now. This database records: place where the animal was
found, who found it, the species, the cause of death, etc. This important database has hundreds
of records, and an enormous potential for a Geographical Information System (GIS) creation
(Diogo 2009).
The original aim, of the present research, was to create a GIS, which ultimately aim was to
produce maps of the main risk of poisoning for the entire Portuguese country (see Figure 1,
Portuguese island not included).
To achieve those aims, it was necessary to stablish a relationship between the poisoning
episodes, environmental characteristics and the human activity. Thus, they were used GIS
techniques, such as 3D Analyst, Spatial Analyst and Geostatistical Analysis were used in ity
(Morrison, 1991; Reis, 1997; Hoef et al, 2001; Clemente et al. 2002; Blanquer et al. 2005;
Soares 2006; Abdi & Nandipati 2009).
