sylviculture intensive

CONT: Les usages industriels du bois ne cessent de croître et, au moins dans certains pays, on doit se préoccuper du déficit de plus en plus marqué de la production locale [...] On est amené à rechercher des méthodes de sylviculture plus intensive qui permettraient d'augmenter la production en matière ligneuse; on entreprend des labourages de sols forestiers, on fait des plantations après explosifs, on s'occupe de fertiliser les boisements par des épandages d'engrais, [...] on combat les pousses de mauvais taillis par des phytocides [...], on utilise de préférence des essences à croissance rapide [...]
CONT: Une méthode de production soutenue du bois, la ligniculture, est un moyen efficace de pratiquer la sylviculture intensive.

OBS: The term incremental silviculture is defined in the British Columbia Forest Act and thus ""intensive silviculture"" is no longer used there. In Ontario intensive silviculture may be considered to include plantation establishment, e.g., using genetically improved planting stock; intensive site preparation, such as spraying herbicides to reduce competing vegetation before mechanical preparation; manual weeding of plantations at early stages.
OBS: In Europe, the more intensive the silviculture practiced, the less the fire losses, so that fire control activities tend to become accidental. The most important reason for this is the intensive utilization. This results in a clean forest floor with all dead and down material removed. ... Added to this is ... the creation of numerous barriers to fire ...
