How are Acacia mangium and Broad-leaved paperbark used?

In order to understand how local people use these two species, GEPOG teams met local stakeholders and locals to find out more.

The problem

Acacia mangium and Broad-leaved paperbark are two plant species introduced into French Guiana that invade dry savannahs, threatening this rare habitat and all associated species. In order to control the expansion of these species, a plan to combat these two invasive plant species is planned as part of LIFE BIODIV’OM.

The use of these species

Despite the invasiveness of these species, it is essential to understand how the local people use these species in order to be able to offer them alternatives that make it possible to fill these uses while avoiding the destruction and the loss of the dry savannas of French Guiana.

The method

The GEPOG teams met the Town Halls of Awala-Yalimapo and Mana, the teams of the Réserve Naturelle Nationale de l’Amana, those of the Association pour la Découverte de la Nature en Guyane (ADNG) and organized visits field but have mostly met with locals with acacias or niaoulis on their plots.
With the help of a questionnaire and a hand-recorded voice recorder, these interviews will reveal more about the uses made of these species, the needs and constraints of the inhabitants.

The objective

The results will be used to feed the control plans currently being drafted, as well as to develop a list of local alternative uses. They will be compiled with further interviews to be conducted on other invaded coastal areas.
