Alternatives procedures for small farming sustainable management of parana pine

Abstract

After the expansion of agricultural frontier occurred in the southern brazilian region, which brought native forest substitution, new  management and alternatives practices were introduced in order to preserve and stimulate new plantings of the parana pine (Araucaria angustifolia ). Alongside, in the last years, silviculturists have been promoting activities of forest development, in special with Pinus, Eucalyptus, Grevillea and bracatinga (Mimosa scabrella) species to face wood depletion of native forest species. At the same time, new legal procedures also contributed to reduce new plantings of parana pine  because it tried to enforce simple preservation with high demands and tough inspection measures. Thus, representing 85 % of land structure in the State of Paraná, discouraged - small farmers were looking for to erradicate this species due to legal over regulation. Therefore, to  vercome this situation, mechanisms were offered to the silviculture management of Brazilian pine which were based in two central points tupgrading the existing laws and to incentive new plantations, specially in the areas set aside for environmental protection called of "Reserva Legal". In this way, the Extension Service (Emater) tried to help this situation with the following prescription: technology diffusion; rewards to stimulate forest producers in the municipality; and formation of farmers groups to collect, select and to sell pine seeds.
