RESUMOO estudo objetivou avaliar os fragmentos florestais, utilizando métricas da ecologia da paisagem no alto curso do rio Una, Ibiúna, SP. Realizou-se o mapeamento de uso do solo e cobertura vegetal para o ano de 2007 e 2017, a partir dos quais foi constatado que houve uma diminuição de aproximadamente 9,40% do total de área de Floresta durante este período. Porém, como a categoria Floresta apresentou a maior área para ambos os anos, a região ainda possui grande potencial para conservação. A partir do mapeamento do uso do solo e cobertura vegetal, foram extraídos os fragmentos florestais, totalizando 105 fragmentos no ano de 2007 e 53 em 2017, sendo a grande maioria de fragmentos pequenos. O total de borda confirmou o efeito de borda e a relação perímetro/área e a dimensão fractal indicaram a forma irregular dos fragmentos, apontando que a área se encontra sob grande pressão antrópica. Sendo assim, este estudo apresenta-se como uma ferramenta para auxiliar na gestão do uso responsável da região, promovendo o desenvolvimento de forma sustentável.

Conservação ABSTRACTThis study aimed to evaluate forest fragments using landscape ecology metrics in the upper reaches of the Una river, Ibiúna, SP. Land use and vegetation cover mapping was carried out for 2007 and 2017, and it was found that there was a decrease of approximately 9.40% of the total forest area during this period. However, as the Forest category presented the largest area for both years, it shows that the region still has great potential for conservation. From the mapping of land use and vegetation cover, forest fragments were extracted, totaling 105 fragments in 2007 and 53 in 2017, the vast majority being small fragments. The border total confirmed the border effect and the perimeter /area ratio and fractal dimension indicated the irregular shape of the fragments, indicating that the area is under great anthropogenic pressure. Thus, this study presents itself as a tool to assist in the management of responsible use of the region, promoting sustainable development.
