new method of regulation of selection or near−selection forest type development
Opis:: In uneven−aged forests, age does not apply to the whole stand but to individual trees. Therefore age of individual trees is rather represented by their thickness, and dbh distribution types become the measure of their age. The distinguished dbh distribution types show individual uneven−aged forest development phases: type A – optimum phase, type B – initial phase, type C – future phase and type D – ageing phase. In the optimum uneven−aged forest development phase, 'prescribed cut according to silviculture needs' should be similar or equal to volume increment. In the initial development phase, such 'prescribed cut' should represent 60−80% of current volume increment, while in the future forest development phase, it should equal the current volume increment or exceed it by 20%. In the ageing forest development phase, 'prescribed cut according to silviculture needs' should be higher than the current volume increment by 10−30%. Selection−type forest management should be a model one for uneven−aged forests. Selection−type forests are close to the natural state and constitute a stable forest ecosystem with high resistance to biotic and abiotic factors and by reducing and dispersing the management risk they better fulfil their multiple functions.

Tytuł:: Regulacja jako współczesna forma aktywnej ochrony przyrody
Regulation as a modern form of active nature protection

passive and active forms of nature protection
new "philosophy" of forest protection
forest sustainability
the modern form of active forest protection
Opis:: The paper presents the negative effects of passive nature protection and demonstrates that some groups of ecologists seem to still ignore these facts. The paper shows that, according to the new 'philosophy' of nature protection, there is neither a real climax biocoenosis nor the state of equilibrium in nature, and that natural succession is not in fact possible. Therefore the return to nature by creating national parks and nature reserves is not realistic. The sustainability of forests cannot be ensured by banning their access, or through their passive conservation, but by regulating the mutually interrelated biological processes, like regeneration, survival, and loss of trees and stands. The abandoning of exploiting non−renewable raw materials, like ore, sand, coal or stone deposits will undoubtedly contribute to their protection and preserve them for the generations to come. However at the same time forbidding the use of renewable forest resources will not support their protection, but will rather upset and interrupt their existence, until their final death. Only active, regulatory activity by man can save the endangered and rare species and natural ecosystems, including forests, from extinction. The common belief that sustainable existence and permanence of many plant and animal species is not possible without human support and regulation should prevail both in forestry and in modern nature protection.
