    Slovenia

    In Slovenia, the Natura 2000 network covers 35.5% of its territory or 286 areas, encompassing 10 forest habitat types. The majority of indicators for the assessment of the conservation status and changes of forest habitat types are to be estimated within the forest management planning framework. In this paper, a hierarchical concept of forest habitat types monitoring in Pohorje Mts (810 km2) was examined and presented, based on landscape structure and position of habitat types in this structure.

    The degradation of soils with high sand content, in the southwest of the state of Rio Grande do Sul, is due to the vegetal cover withdrawal, forming sandy areas called "areais", which pose a risk to animal husbandry and the prairie ecosystem. A technique of revegetation with cover crops such as Avena strigosa Schieb. and Lupinus albescens H. et Arn., was developed to reduce the soil particle movement by eolic erosion.

    Growing demands for outdoor recreation have led to increased levels of crowding, displacement, competition and antagonism among alternative recreational uses. Recreational activities interact with differing degrees of compatibility resulting in various outcomes. In this review, we critique the relevant literature on recreation conflict, use compatibility and additivity with a focus on the interaction that takes place among alternative recreational uses.

    Abandoned Polish mining areas are commonly heavily transformed so that they endanger no longer the environment. A disadvantage is that the newly created areas commonly contribute to the monotonous urban-industrial landscape, rather than providing additional value. This is partly due to legislation that hampers a more diversified management of abandoned mining areas as potentially valuable landforms. One of the legal barriers that restricts the possibilities of making these areas more attractive, regards the utilization of remaining exploitation holes (i.e.

    Esta pesquisa aborda a atividade madeireira sob o regime de concessão florestal desenvolvido no Estado do Acre. Os objetivos do presente estudo são: identificar o custo da produção do manejo florestal sustentável (MFS) para produção madeireira, tendo como base a Floresta Estadual do Antimary (FEA); e, quantificar o valor, a ser pago pela terra, numa área destinada como floresta pública de produção, no ano de 2005. Para tal, foi considerada, como premissa básica, um ciclo de corte de 15 anos.

    The process of agricultural abandonment has been taking place for the last decades all around Europe. This process has special effect on mountain livestock farming, as it is the case of that of Catalan Pyrenees, which is characterised by an extensive management of the herd between the alpine grasslands in summer and the hay meadow of the lower valleys in winter. The process of agricultural abandonment, apart from the obvious closing down of the exploitations, also implies a gradual decrease of the management intensity of the farming exploitation.

    Rational land use decisions of privatelandowners are analysed in the framework of CommonAgricultural Policy and other public support schemeseffective in Finland in 2003. Net present values arecomputed for a marginal hectare of a typical Finnishfarm. Three alternative land uses are considered:traditional cultivation of oats (Avena sativa L.),cultivation of reed canary grass (Phalaris ArundinaceaL.) for energy production, and production of Norwayspruce (Picea abies [L.] Karst.) timber.
