The illegal trade of fauna in Brazil is characterized by the lack of wide and
systematic data from official or scientific sources and it's difficult to
evaluate the real dimension and impacts of such activity on Brazil, São
Paulo State or other Brazilian State. This research was made intending to
collaborate with the changes necessary to alter the present panorama of
lack of data and information. A total of 8.925 documents about fauna
apprehension by the Polícia Ambiental of São Paulo State from 1999 to
2003 were surveyed. The results counted a total of 45.444 wild animals
apprehended belong to 341 species, comprising 41.884 (92,17%) birds
with 263 (77,13%) species, 2.156 (4,74%) reptiles with 27 (7,92%) species
and 1.404 (3,09%) mammals with 51 (14,96%) species. The apprehended
birds were related to 23 Orders and 56 Families with approximately 24% of
the species considered threatened of extinction, 13% with no geographic
range in São Paulo State, 4% exotic, 1% invaders and 0,4% hybrids. The
species responsible for up to 50% of the apprehended specimens of birds
were: codorna (Coturnix coturnix), canário-da-terra (Sicalis flaveola),
coleirinha (Sporophila caerulescens) e pássaro-preto (Gnorimopsar chopi).
With regard to the mainly destinations of the 41.884 birds apprehended,
approximately 38% was categorized as No Declared Destinations, 25% as
Other Destinations and 10% as Releases. The apprehended reptiles were
related to 4 Orders and 14 Families with approximately 50% of the species
considered threatened of extinction, 8% with no geographic range in São
Paulo State and 7% invaders. The species responsible for up to 50% of
the apprehended specimens of reptiles was: tigre-d'água (Trachemys
dorbignyi). With regard to the mainly destinations of the 2.156 reptiles
apprehended, approximately 72% was categorized as No Declared
Destinations, 8% as Releases and 4% as CETAS. The apprehended
mammals were related to 9 Orders and 22 Families with approximately
67% of the species considered threatened of extinction, 2% with no
geographic range in São Paulo State, 6% exotic, 4% invaders and 2% vagrants. The species responsible for up to 50% of the apprehended
specimens of mammals were: capivara (Hydrochaeris hydrochaeris),
gambá (Didelphis albiventris) e tatu-galinha (Dasypus novencinctus). With
regard to the mainly destinations of the 1.404 mammals apprehended,
approximately 35% was categorized as Discarded, 25% as Releases and
18% as No Declared Destinations. The lack of data about apprehended
species and their destinations in São Paulo State become evident in the
fact that there are no data (from scientific or official sources) to provide a
direct comparison with the results showed by this research. So, the
construction of a wide and systematic database about these issues and
the planning of environmental public policies, truly focused on the
conservation of the biodiversity in São Paulo State, are a necessity that
can't be postpone any longer.
