OBJECTIVE
To assess and contrast the characteristics of assisted and
naturalregeneration with regard to ecological restoration in a dry
tropical.forest
ssisted regenerationTrees are planted to assist the
process of natural regeneration
atural RegenerationThe regeneration process takesplace without

AssistedRegeneration
NaturalRegeneration
,In the 90s the local community of the Monte Alto Reserve has
initiated a restoration project on very degraded land resulting,
.from an agricultural use with the main objective of hydrological
regulation and increase of water availability The restoration
, .technique is based on assisted regeneration which consists in
planting native species to enhance natural regeneration Less
, , .degraded areas have been abandoned in the period without
any active management allowing natural succession process According
to
,local people there has been an increase of the water
availability in the river since the restoration project has
been
.implemented
