Propriedades físicas dos lenhos juvenil e adulto de Pinus elliottii Engelm var. elliottii e de Eucalyptus grandis Hill ex Maiden

The juvenile wood presents great difference in its anatomical and physical properties in relation to the mature wood. That heterogeneity of the wood causes a series of upset for the processing industry. The present research had as objective the study of the physical properties of the juvenile and mature wood of Pinus elliottii Engelm var. elliottii, with 25 years of age and of Eucalyptus grandis Hill ex Maiden, with 30 years of age, coming from the Experimental Station of Itapetininga and State Forest of Santa Barbara, belonging to the Forest Institute of the state of São Paulo. From both species there were taken from radial boards, specimens with dimensions of 20x30x50 mm, for the determination of density, swelling and swelling coefficient of the juvenile and mature wood. The results of the species showed that the mature compared with the juvenile wood presented: (1) an increase in the values of the basic density, at 0% and at 12% of moisture content and of the volumetric, radial and tangential swelling at 12% moisture content and maximum coefficient of radial and tangential swelling; (2) a reduction in the values of longitudinal swelling at 12% and maximum and of the longitudinal swelling coefficient.

Caracterização dos elementos físicos da bacia do córrego Santo Antônio (Rio Claro/SP)

O objetivo desta pesquisa foi caracterizar os elementos físicos da bacia do córrego Santo Antônio, buscando compreender a influência que a área de entorno dessa bacia exerce sobre a Floresta Estadual Edmundo Navarro de Andrade (FEENA). Para isto, foram elaboradas as cartas geomorfológica e de uso do solo, além da compilação de dados geológicos, pedológicos e climáticos. Essa influência foi avaliada em termos da dinâmica de remobilização de materiais provenientes das nascentes, que não pertencem a FEENA, e que se constituem, portanto, em área de uso agrícola. A análise das características físicas indicou que essa área é susceptível a ação dos processos morfogenéticos e que estes foram intensificados e acelerados pelo uso do solo ao redor das nascentes. Verifica-se, assim, a necessidade de se reavaliar esse uso e de se fiscalizar o cumprimento da própria legislação ambiental, no que se refere ao uso e ocupação do território, em fundos de vale.

Avaliação econômica de sistemas agroflorestais implantados para recuperação de reserva legal no Pontal do Paranapanema, São Paulo

O Pontal do Paranapanema, extremo oeste do Estado de São Paulo, é conhecido em todo o Brasil devido aos conflitos pela posse da terra, protagonizados pelo Movimento dos Trabalhadores Rurais Sem Terra (MST), que transformou significativamente a paisagem da região, onde atualmente se observam pequenas ilhas de assentamentos rurais imersos numa matriz de grandes pastagens. O Código Florestal prevê que esses assentamentos, assim como qualquer propriedade rural, deve manter 20% de sua área com cobertura vegetal arbórea. Essa área, conhecida como Reserva Florestal Legal, deve ser restaurada, caso não exista. Assim, esta pesquisa se desenvolveu no assentamento Santa Zélia, Município de Teodoro Sampaio, São Paulo, numa área de 15 ha de Reserva Legal. Seis famílias desse assentamento foram responsáveis pela restauração da área, através de módulos agroflorestais (Taungya) temporários. Dois indicadores foram utilizados para avaliação econômica da produção agrícola na área: Valor Presente Líquido (VLP) e Relação Benefício-Custo (RB/C). Os resultados indicaram valores positivos em todas as famílias analisadas, levando à conclusão de que sistemas agroflorestais podem ser adotados na recuperação de áreas de reserva legal em propriedades rurais. Sua maior ou menor viabilidade econômica irá depender de um manejo mais intenso na área para produção agrícola e de preços satisfatórios para venda no mercado.

Relação entre a precipitação anual e o incremento em volume de árvores amostradas em plantações de Pinus taeda

This work was based on a complete tree stem analysis to assess the growth behavior and current annual volume increment (CAI) of four individuals of Pinus taeda sampled in populations located in the 'Avare II' State Forest and 'Itapeva' Experimental Station, State of São Paulo. The relationship between the rainfall time series and CAI index was examined by means of cross-correlation coefficients. The convergence coefficients (GL) between the series were calculated. In the individuals that showed a statistical significance in the cross-correlation between the time series, the previous year's rainfall significantly affected the current annual volume increment in the year under consideration. The GL values between the series were higher in 'Itapeva'. Since the two sites showed no significant difference in rainfall distribution, the difference was attributed to the soil texture at 40-60 cm - medium in 'Avare' and clayey in 'Itapeva', so the CAI of the 'Itapeva' plantation reflects the higher availability of water.

Critérios para indicação de espécies prioritárias para a restauração da vegetação de cerrado

Knowing the attributes of the most suitable species to overcome the obstacles in different environmental conditions is an important tool for ecological restoration. To evaluate the comparative performance of native Cerrado species being cultivated at an arboretum (Assis State Forest, Assis, SP, Brazil), we categorized 106 species by the following attributes: average annual increment in height and crown diameter, survival rates, frequency of herbivory, frost susceptibility and seed dispersal syndrome. The score of each attribute may vary from 1 to 3, and the value of a species for restoration was generated from the sum of the scores for the different attributes converted to the scale of 0 to 100. Analyzing the species altogether, survival was 70%, the average annual increment was 30 cm in height and 21 cm in crown diameter. Only 8% of the species showed high susceptibility to frost and 17% high frequency of herbivory. Eighteen species had scores above 80, being the first Annona crassiflora, Cecropia pachystachya, Enterolobium gummiferum, Plathymenia reticulata e Protium heptaphyllum. In this group are the species that gather the highest number of favorable attributes for the restoration of Cerrado vegetation. We generated two separate lists of ten species of higher value, one for the cerrado sensu stricto and the other for cerradao the forest type of cerrado vegetation. We believe that using these species accelerates the recovery of vegetation structure and thus provide the restoration of ecological processes of ecosystems undergoing restoration. At the end of the list are species of low scores, which, if used, can lead to higher costs or delay in the recovery of structure and ecological processes of the ecosystem being restored.

Análise microclimática funcional da Floresta Estadual Edmundo Navarro de Andrade: comparação entre os períodos 1889-1917, 1971-1999 e 1999-2011

Currently the forests around the world face different aspects of weather. Global climate change and its adversities alter significantly the dynamics of the forest, directly influencing the operation. Human activities interfere in the functions of forests, either by removal of vegetation, either by reforesting deforested areas. Given the influence of human activity and climate change on forests, this project presents a comparative and analytical situation, the microclimatic level, the State Forest Edmundo Navarro de Andrade (FEENA), in Rio Claro. We measured the temperature maximum, minimum and average in different periods surrounding the FEENA, from 1889 to 1917, 1971 to 1999 and from 1999 to 2011. What allowed to suggest changes in the microclimate of your surroundings and probably in forest dynamics

Proposta de trilha interpretativa para a Floresta Estadual Edmundo Navarro de Andrade (FEENA) - Rio Claro

Within the current context of environmental degradation, primarily caused by unsustainable pat terns of production and consumption (AGENDA 21, 1992), the Protected Areas (PAs) are considered internationally as one of the most successful measures for the conservat ion of biodiversity, according to the Union for the Conservation of Nature (IUCN). The city of Rio Claro (Sao Paulo, Brazi l ) has a significant conservation area in both environmental aspects as historical and cultural, the State Forest 'Edmundo Navarro de Andrade' (FEENA). Beyond the conservation measures, there is a need to develop environmental education that encourages community participation and appreciation in the unit 's maintenance and protection, as well as provide moments of reflection that could conduct perceptual changes, behavioral, attitudinal and evaluative on relations between human beings and their environment . This work brings the proposal to create an interpretive trail in the area of public use of FEENA to contribute to the Unit Management Plan in order to make it an Environmental Education tool. To prepare the planning of the interpretive trail, a deep bibliographic and cartographic review was performed on the subject. It was applied questionnaires in order to know the visitors better and map the features of public visitation, as well as map the visitor preferences about how they would like to receive information on the area and expose field studies in the track site. The trail was traced taking into account the environmental and social aspects, we propose a track suspended above the ground, in order to affect as little as possible and to include the area in the context of PAs people with reduced mobility and visually impaired
