Protecting threatened Over-seas biodiversity

Study begins on Madagascar pond heron feeding grounds

In October 2019, GEPOMAY met the botanist Vincent BOULLET, who came to work with the GEPOMAY association to study the wet meadows where Madagascar pond herons feeds in Mayotte.

First conclusive results

The visit of this specialist allowed to learn more about the preferences of the species. The species is particularly found around plants of hersia pereri and aquatic owl, which indicate a high soil moisture and therefore a greater presence of insects. Grazing by zebus in some wet meadows would appear to be beneficial to the species as it would conserve low vegetation in which the Madagascar pond heron could more easily circulate.

Threatened spaces

The wet meadows are threatened by the cultivation (dream and banana), by the drying caused by the human constructions thus modifying the composition of the vegetation and consequently the quantity of insects, food resources of the Madagascar pond heron. These wet meadows are also impacted by the increase in salinity (rising waters, Mayotte sink), the loss of surface (constructions, rising waters and undergrazing) as well as the invasion by some invasive alien species (IAS) plants.

The actions of GEPOMAY

In order to respond to the threats to these wet meadows, GEPOMAY will implement actions within the framework of the Life BIODIV’OM program to protect these sites. GEPOMAY will organize consultation meetings with farmers to develop sustainable management of their activities. Awareness-raising operations through surveys of neighboring populations will be put in place as well as management actions against invasive alien species.
