OVERVIEW OF THE REGIONAL CONTEXT
• The most remarkable and important concentration of biological diversity in the world: in less than 500k km2
– 8 endemic plant families and more than 12,000 endemic plant species
– The most important priority in the world for primate conservation, with 5 endemic families, and 48 species
– 5 endemic bird families, 110 species– 346 species of reptile and 154 of amphibian, almost all
endemic– Two families and 95 species of endemic freshwater fish

National Context
• Durban Vision- triple the protected areas by 2008• Reorientation of focus of forest management from
exploitation to conservation, based on ecosystem service values
• Recent decrees suspending logging and mining in forest areas
• National forest zoning plan underway to implement the Durban Vision – the Mantadia-Zahamena corridor is a key piece of this
![Page 5: OVERVIEW PRESENTATION TO PLENARY](https://reader035.fdocuments.in/reader035/viewer/2022062305/56814e4b550346895dbbd496/html5/thumbnails/5.jpg)
The Durban Vision - triple the protected areas of Madagascar
President Marc Ravalomanana: We can no longer afford to let the forest go up in smoke or
let our many lakes, marshes and wetlands be destroyed, nor can we unwisely exhaust our marine resources. I would like to inform you of our decision to increase the protected areas from 1.7 million hectares to 6 million hectares over the next five years …through strengthening of the present national network and implementation of a mechanism for the establishment of new Conservation Sites.

New Conservation Sites
Multiple-use areas managed by a variety of actors from national government, local government and NGOs through local communities.
Up to 75% of each Conservation Site will allow sustainable use of biodiversity.
At least 25% of each site is a strict conservation zone
Three basic management rules- no commercial logging, no mining and no deforestation

IDENTIFICATION OF POTENTIAL CORRIDOR
• Priority setting:
- Forest Zoning (DGEF)- PlanGrap (ANGAP)- Priority-setting workshop 1995 (PRISMA)- IBAs (BIRDLIFE)- Total biodiversity coverage 2001 (CI)- Priority setting of endemic plant families (MBG)

Corridor outcome
Viable populations of threatened species and
restricted range species of Zahamena-Mantadia
corridor are conserved through sustainable
funding and efficient management of 400,000ha of
protected areas (including conservation sites)
Conservation actions contribute to the
improvement of human well being.

Issues to resolve at the corridor level
• The basic rules of management for the corridor (no logging, mining or deforestation) give us a basis for conservation Where should these rules be applied?.
• What supplementary rules are necessary, to be applied where, in order to conserve the important biodiversity of the corridor?

Deforestation
Between 1974 and 1994: around 90% of forest <800 m are lost
Between 1990-2000:
0-800 m – 17.8% of the remaining forest are lost
800-1200 m – 5%
1200-1600 m - <1%

Intervention methods
• Integration of biodiversity conservation scenarios into communal, regional and provincial development plans
• Support to partners in biodiversity conservation- grants to planning and implementing organizations, studies of threatened species,
• In part through partnership with USAID regional alliance, support in acquiring development aid in key areas- NGO capacity development, proposal development
• Support to urgent development activities
