ABSTRACT
Fast growing of weed species, like Panicum maximum inhibits forest species development in rehabilitation of degradaded areas and proporcionales fire occurrence during dry season. Adensed plantation system utilizes ecologycal conccepts based on successional processes in tropical forests, utilizing high species diversity and trying to mantatn adequated proportion between pioneer, secondary and climax species. Like late stages of successional processes on tropical forest, adensed plantation uses zoochorichous species in major proportion than other dispersal systems. Plantation is realized on adensed way with 1 m2/plant, and a line of pioneer species followed by a line of pioneer intercalated with non-pioneer. At this way, each non-pionner is surrounded by four pioneer, wich proporcionate shade for its development. Preliminary results demonstrated high survival in the adensed system, comparated with traditional one (1 plant/4 m2) and reduction of fire occurrence. Adensed plantation promoted fast covering of soil surface, reducing the necessity of mantainance. Although inicial costs of adensed plantation were higher than traditional, final costs are reduced because of the minor number of maintenance services.
Key words:
Adensed plantation; Tropical forest.
