Critérios técnicos e de participação social para a recuperação florestal: quais as diferenças na definição de áreas prioritárias?

The Jararaca River Basin suffers significative environmental impacts caused by inaccurate land use. In Brazil, the areas for permanent preservation are defined and protected by the 2012 Federal Law 12.651. These areas are located in the bank side and other specific places. The objective of this paper was to analyze the results of possible alternatives in function of different procedures used in the proposal elaboration. The methodology used was the elaboration of a priority map for the recovery of these areas using the Geographic Information System with multicriterial analyses and comparing it with the guidelines from the Jararaca River Basin Management Plan. As a result, there were identified differences in the priorities defined by technical issues from the priorities defined by public consultation process.

Avaliação técnica e econômica do forwarder na extração de madeira em povoamento de eucalipto de primeiro corte

This study aimed to technically and economically evaluate the Forwarder performance in the first cutting wood extraction from a Eucalyptus grandis plantation. Technical analysis included a movement and timing study by continuous method, and the productivity was determined using the extracted wood volume in cubic meters. Economical analysis included operational costs parameters and wood extraction cost. Results referred to the effective operational performance. Loading and unloading activities responded for more than ¾ of the total time of effective Forwarder operational cycle. Operational costs were influenced by maintenance and repair costs. The estimated cost of extraction was US$ 0.97 per cubic meter.

Aplicação de análise multicriterial para determinação de áreas prioritárias à recomposição florestal

Using the Geographic Information System (GIS) and taking into account its capability to analyze spatial data, a database of updated spatial data from the sub-basin of the Descalvado stream, Botucatu, SP, was developed to provide an evaluation and diagnosis of the area concerning land use and the degradation processes therein. Through GIS, priority areas for forest recovery were defined by Multicriteria Evaluation and using the Ordered Weighted Average method. The latter allows the decision maker to define the area to be recovered, facing limitation of resources, among one of the proposed scenarios, or do it in stages. The study showed that there are accelerated erosion processes in the headwaters of the springs of water bodies; there is also fragmentation of native vegetation, especially in hillside areas, and little presence of native vegetation in riparian areas. The application of the multicriteria analysis using the Ordered Weighted Average was important as it systematized and discriminated scenarios of priority for forest recovery.

Recomposição florestal visando à conservação de recursos hídricos na bacia do Rio Pardo, SP

The Pardo River Basin represents the situation of disorderly process of use and occupation of land, where forest fragmentation is one of the results. This study evaluated the use of Multicriteria Evaluation in a GIS, specifically through method Weighted Linear Combination, the generation of map of priority areas for forest restoration in the initial part of Rio Pardo Basin, SP, aiming the conservation of water resources. It can be concluded that, the Multicriteria Evaluation in a GIS is appropriate to the mapping of priority areas for forest restoration. The map of suitability for forest recovery may be useful in the environment planning, providing public and environmental agents making decision, based on a method that takes into account the landscape as a whole and the priority is the conservation of water resources.

Elaboração de um roteiro interpretativo para trilha de ciclista da Florestal Estadual Edmundo Navarro de Andrade, Rio Claro/SP

The State Forest Edmundo Navarro de Andrade (FEENA), Rio Claro/SP has a huge potential for cyclists tracks; the Unit already have a trail at the principal entrance, passing by firebreaks bordering the towers quadrants and finishing at the municipal road. This work aims the ambiental interpretation of this trail already established and implant activities planned before at the public use program of the State Forest according to the management plan of the Unit; to interpret the tracks for mountain bike cyclists; promote the conservation of natural, historic and cultural resources of the Forest. At the present work has been accomplished the Ambiental Interpretation through the panels, containing the characteristic native flora and fauna, the existing water resources at the Unit and also the representatives individuals of the exotic arboreal species, found around the trail. Ten points were chosen for interpretation, therefore, for preparation of the script it was considered besides the bibliographic literature, experiences of project team members at FEENA, Unit Management Plan knowledge relating the gaps in the public use program and field work. The panels contain figures and texts about the chosen topics, to promote a language easily understandable to the visitor and concomitantly, inform to the population who attends the Unit, increasing this way the user satisfaction

Corte foliar e tempo de transplantio para o uso de plântulas do sub-bosque na restauração florestal

O uso de plântulas da regeneração natural tem sido recomendado como estratégia para produção de mudas visando à restauração florestal, contudo muitos aspectos técnicos desse método ainda carecem de investigação científica. O objetivo deste trabalho foi avaliar o efeito da redução da área foliar e do transplantio imediato na sobrevivência e crescimento de mudas de espécies arbóreas produzidas a partir de plântulas obtidas da regeneração natural. Plântulas de Esenbeckia leiocarpa (Rutaceae), Eugenia ligustrina (Myrtaceae) e Maytenus salicifolia (Celastraceae), obtidas em remanescente de vegetação secundária de Floresta Estacional Semidecidual em Bofete, SP, foram extraídas do solo e submetidas aos tratamentos: I) redução de 50% da área de cada folha e transplantio imediato; II) nenhuma redução de área das folhas e transplantio imediato; III) redução de 50% da área de cada folha, manutenção das plântulas em água e transplantio 24 h após a coleta; e IV) nenhuma redução de área das folhas, manutenção das plântulas em água e transplantio 24 h após a coleta. As mudas foram avaliadas com relação à sobrevivência e ao crescimento em altura, ao longo de oito meses. Os resultados evidenciaram que nem o corte das folhas ou a manutenção das plântulas dentro de recipientes com água por 24 h antes do transplantio afetaram os parâmetros avaliados. Assim, para as espécies estudadas a redução da área foliar e o transplantio imediato são desnecessários para a produção de mudas em viveiro a partir de plântulas obtidas da regeneração natural.
