The Ranomafana National park is incredibly rich in biodiversity, hosting 98 species of amphibians and 62 reptile species on 416 square km (in USA 285 and 251 respectively, but on 9,826,675 square km). 

The villages of Vohitrarivo, Vohimarina and Sahofika, just on the border of the park, have their environment extremely degraded. 

Fortunately, one of the first and last plant growing back after the land has been burnt is bamboo - the main food of the Great Bamboo lemur. 150 specimens of the population of this species are found in this degraded habitat, which represents 1/4 of the population.


Major issues


First destruction of the forest cover in the park is a real disaster. In addition to the plant disappearance, 1/3 of the 115 bird species the majority of the frogs of the park are strictly forest dwelling. 

If the human populations remain in  absolute poverty (currently at the level of undernourishment), it would be impossible to stop them from destroying further the forest. 

The growth of bamboo after the fire is equally threatened, as the population burns the land again to produce cash crops.



The project and the prospects for change 


The population lives in an extreme poverty, as the destruction of the habitats generates very low incomes. This site contains some natural products of international interest (the Longoza has been highlighted as Dior’s flagship product), but also crops such as ginger which could be developed for the local market. 

Helpsimus’ local coordinators and the Ranomafana National Park have had very enthusiastic feedback from the village communities, which are seeking assistance and are ready to follow a management plan to ensure the Great Bamboo lemurs’ conservation. 

Therefore, the aim of the project is to help the local communities to lift out of extreme poverty and to implement a landscape management plan covering the area of the three villages that would allow the conservation of the Bamboo lemur habitat, key to its survival. 

The project activities will be the following :

  • The implementation by the scientists and the local population of the landscape management plan to intensify agriculture in certain areas, while conserving key areas for the lemurs. 
  • The improvement of agricultural production, especially through the development of ginger and coffee plantations (these products are adapted to the area and are profitable on the local market), and the setting up of a storage facility. 
  • The construction of infrastructures (a bridge to facilitate access to school during rainy season) and sensitization to sanitation and disease prevention.


Committed partners


The emergency to initiate field actions has been seen by a biologist, Delphine Roullet, who was in charge of the European captive breeding program to save the Great Bamboo lemur from extinction. The Bamboo lemur project is a three-actor management program, including the NGO Delphine created (Helpsimus), the representatives of the three villages and the Ranomafana National Park.
