This page lists all the information, the exchanges and the products around the Macaya National Park monitoring

Macaya National Park is the core area of ​​the Hotte Massif Biosphere Reserve, designated a World Biosphere Reserve by UNESCO in 2016. It has the largest concentration of endemic species in the world: 102 species of ferns, including three endemic, 141 orchids, including 38 endemic, which only exist there. The park was hit hard by Hurricane Matthew. Impact estimates ranged from 50 to 95% depending on the park areas.

Following Matthew, the park has implemented a new management plan, and RO activities have been designed to support these activities, making it possible to better understand the evolution of anthropogenic impact during the recovery period.

The first priority was to determine the impact in the park, both immediately following Matthew, and in the following years, given the new impetus for forestry activity. Funded by CNES, SERTIT worked with very high-resolution images in order to establish this impact assessment in 2017. The state of the park was assessed by the Copernicus Risk and Recovery activation in 2018. Subsequently, a more targeted activity proposed by the Inter-American Development Bank (IDB) funded by CNES aimed at understanding anthropogenic activities in the park and in bordering areas was initiated. This activity aimed at mapping the park's trails. One of the objectives of this study is to see if when economic activities are developed in the bordering area the parts of the associated park are less affected by humans.

Analysis of Results and Outlook :

L’étude à long terme du parc par satellite présente des défis. Dans les mois qui ont suivi l’ouragan, il a cependant été possible de mesurer la reprise de la végétation et de distinguer végétation nouvelle et ancienne. Le parc présente une topographie montagneuse, ce qui présente de nombreux défis au niveau des ombres pour l’analyse de données optiques mais aussi des nombreux nuages cachant les relifes. L’analyse de l’impact anthropique requiert des données à très haute résolution. L’analyse proposé par la BID a permis de dégager un impact autour des zones d’intérêt. Depuis 2019 il est fort probable que la végation ait repris ses droits dans les zones non peuplés : les images montrent une forte reprise de la végétation. Malheureusement les activités anthropiques encore présentes ne servent pas ce redressement.
