CONSERVATION OF THREATENED TIMBER TREE SPECIES IN THREE MALAGASY PROTECTED AREAS

Most native Malagasy trees are threatened by high rates of forest loss, but species valued for their timber are additionally threatened by aggressive and typically unsustainable selective exploitation. Consequently, even within remaining forests, these species are unnaturally rare and even locally absent. Such is the case in three protected areas where MBG supports community-based conservation: Analalava; Ankarabolava-Agnakatrika; and Makirovana-Tsihomanaomby. To ensure that these species are effectively conserved and flourish once again at these sites, we propose to implement three linked strategies :

1) forest policing to prevent commercial exploitation of timber and shifting cultivation ;
2) provision of alternative timber sources for the community in the degraded landscape surrounding the forest ;
3) restoration of degraded forest within the protected areas using a species mix including seedlings of threatened timber species.

We are fortunate to have received a grant from the Franklina Foundation to help us over three years to implement a program of activities included within the last of these strategies.

+ - Target species

The tree species targeted in this project are all species that are recognized as being threatened and also exploited for their wood.
They are as follows :

Analalava

  • Millettia hitsika (Fabaceae), CR
  • Baudouinia louvelii (Fabaceae), EN
  • Sideroxylon gerrardianum (Sapotaceae), EN
  • Schizolaena manoboensis (Sarcolaenaceae), EN
  • Pentachaena orientalis (Sarcolaenaceae), EN

Ankarabolava-Agnaktrika

  • Brexia apoda (Celestraceae), EN
  • Bathiorhamnus macrocarpus (Rhamnaceae), EN
  • Viguieranthus brevipennatus (Fabaceae), EN

Makirovana-Tsihomanaomby

  • Rhopalocarpus randrianaivoi (Sphaerosepalaceae), EN
  • Rhodolaena macrocarpa (Sarcolaenaceae), EN
  • Dialium madagascariense (Fabaceae), VU
  • Schizolaena rosea (Sarcolaenaceae), VU
  • Garcinia dauphinensis (Clusiaceae), VU

In addition, all species of Sapotaceae growing within these protected areas are targeted by the Project since, although the risk of extinction of most species has not yet been evaluated, we believe that most are threatened due to being exploited preferentially for timber. These are not named here since the taxonomic classification of these species remains unclear and the risk of extinction for most has not yet been published. The three sites combined probably include some 20 species of Sapotaceae.

+ - Goal

Prized threatened timber species flourish once again in the three target protected areas

+ - Specific objectives

Objective 1 : At end of Year 1, the presence, identity and status of the 13 target threatened timber species (+ca. 20 species of Sapotaceae) is confirmed and information is available on their habitat to guide the development of restoration plans and also to direct the collection of their seed.

Objective 2 : By end of Year 1, at each of the three sites, our restoration ecologist, the protected area manager, the local community, and representatives of local and regional government understand and agree on the planned restoration work, designed within a framework of internationally recognized best practice and adapted to our knowledge of specificities.

Objective 3 : By end Year 2, 50,000 seedlings of native trees including 10% seedlings of target threatened timber species are available at each site to implement the restoration plans.

Objective 4 : By end of Year 3 at least 40,000 (anticipating 20% mortality after 12 months) robust seedlings of native trees, including 10% seedlings of target threatened timber species, are growing at each of the three protected areas within multiple restoration plots totally 25 hectares.

+ - Activities
  1. Botanical research to confirm the presence and identity of the target threatened timber species at the three protected areas and to describe their status at these sites.
  2. Concertation of stakeholders at each site, under the leadership of the restoration ecologist, to develop an agreed and model restoration plan.
  3. Production of 50,000 seedlings of native trees, including the threatened target timber species, for use in restoration at each site
  4. Launching restoration of 25 hectares of critically degraded forest within each of the three protected areas using a mix of species, including the target threatened timber species
