Soil Management and Crop Yield

Despite being widely distributed on the Brazilian Cerrado, C. obrieni is classified as endangered inhabiting the “cerradão” and riparian vegetation mixed with the bamboo Guadua paniculata. On Goiás State it has been found on different sites even though the low potential to its vegetation occurrence. Thus, we do an environmental diagnosis on C. obrieni incidence sites, identifying soil cover and major land uses, fragments with potential to support its ecological requirements and the main threats to its conservation. Results demonstrate that the soil cover and use matrix on Porangatu and Novo Planalto quadrants are dominated by agro pasturelands. On Minaçu 1 and Minaçu 3, the native vegetation area is a little higher than human modified areas, while on Minaçu 2 different Cerrado physiognomies predominate on the landscape. Average size of potential fragments on Novo Planalto and Porangatu were significantly lower than Minaçu fragments, predominating vegetation fragments smaller than 10 ha in all quadrants analyzed. Main threats to C. obrieni are associated to deforestation and fire, generated chiefly by agriculture and pasture expansion over native vegetation.Key words: Potential areas, habitat loss, local extinction, Celeus obrieni.
