The Municipal Biological Reserve of Serra do Japi shelters an important forest remnant of Atlantic Rainforest in the state of São Paulo. For its ecological importance, were created instruments for environmental and territorial management of the Conservation Unit, with the regulation of the use and occupation of the land in its Buffer Zone (BZ) in 2004. The objective of this study was to analyze the evolution of the land cover in the BZ region of the Municipal Biological Reserve of Serra do Japi in Jundiaí-SP, between 1989 and 2010. It was used in this study the image analysis of the satellite LANDSAT-TM5, with the help of software ILWIS and IDRISI. The results showed that urban occupation has increased 37.47% and the agro pastoral and reforestation areas have decreased 36.62% and 72.22% respectively, while forest areas have increased 49.57%. However, the relative importance of the forest area in BZ ranged from 46.60% in 1989 to 69.71% in 2010, leading to the conclusion that this region was favored by changes in land cover in the period evaluated, despite strong pressure for urban expansion in its surroundings.

Due to the considerations on the Legal Forest Reserve, the aim of this paper is to show the distribution of the farming areas in the region and their application – especially natural forests. Also, to compare the municipal values with those stated in the Brazilian Forest Code in order to analyze the process of implementing 20% of forest area in relation to the total farming area, at municipal and regional levels, not considering the areas of each of the farms nor the watershed to which they belong with the Brazilian Forestry Code. The work results show that all municipalities in the region of Botucatu do not have forest areas equal or greater than 20% of total area. Therefore, a non-exploratory reforestation procedure will have to be implemented to follow legal requirements. Finally, the results show that the city of Areiópolis will face the greatest difficulties in implementing the 20% of forests with regard to the Legal Forest Reserve, until 2021, when the deadline stated by the Legal Code expires. According to the same variables, the municipalities of Anhembi, Conchas, Laranjal Paulista, Pereiras, Pratânia and São Manuel will face medium-level difficulties, whereas Bofete, Botucatu, Itatinga and Pardinho will implement it the easiest way.

Devido às suas cracaterísticas físico‐químicas e geológicas, estuários e lagunas acham‐se entre os ambientes mais sensíveis para a contaminação de metais e, em vários casos, este aporte de metais está relacionado à atividade mineira nas áreas a montante do curso de água, não raro a muitos quilômetros de distância. O sistema Cananéia‐Iguape consiste em um complexo de canais estuarino‐lagunares, localizados na Reserva da Biosfera do Lagamar. Esses canais são bordejados por vegetação de mangue exuberante, e são um importante criadouro natural de espécies de organismos de interesse commercial, e base da economia da população local.
