The forests of Príncipe are among the 200 most important biodiversity areas in the world. Recognising the importance of protecting the island’s endemic plant and animal species, in 2016 Fauna & Flora International (FFI) began extensive island-wide biodiversity surveys and 3D mapping to better understand the conservation efforts required. The surveys found dozens of endemic bird, invertebrate and reptile species – many of which are already facing extinction and remain poorly known or even undescribed in science. Urgent action (including research) for the critically endangered Príncipe thrush was identified as a high priority, with fewer than 300 individuals left in the wild.

The ocean around São Tomé and Príncipe is a marine biodiversity hotspot due to its high levels of species endemism. Sadly, however, overfishing and destructive fishing practices are posing an increasing threat and contributing to the rapid decline of fish stocks and degradation of marine ecosystems. This poses a serious threat to local fishing communities who rely on marine resources for their livelihoods. FFI is therefore working with partners on the islands to engage with local stakeholders, including government and coastal communities, to promote sustainable use of marine resources through the establishment of co-managed marine protected areas.


We aim to protect Príncipe’s remarkable forests and their wildlife by:

  • Establishing conservation initiatives to protect the Príncipe thrush, including conducting research, stabilising its population, and reducing illegal hunting.
  • Conducting baseline population assessments of several undescribed bird, invertebrate, and reptile species.
  • Increasing understanding and protection of Príncipe’s threatened and important tree species.
  • Supporting and building the capacity of local organisations and individuals to carry out  conservation work.

We aim to protect the ocean around São Tomé and Príncipe by:

  • Establishing a network of 1,000 km2 of marine protected areas (MPAs) and sustainable use zones to promote the recovery of marine ecosystems and biodiversity through the reduction of unsustainable and illegal fishing.
  • Increasing and diversifying the livelihoods of local communities, and ensuring their participation in the establishment and management of the MPAs.

Our work

Our work in São Tomé and Príncipe strikes a balance between direct conservation action and securing sustainable local livelihoods. Initiatives include raising environmental awareness, building conservation capacity, and diversifying the livelihoods of communities, in particular through direct support to local partner organisations.


FFI conducted the first systematic botanical survey of the island. As the biggest joint plant research effort ever to be undertaken on Príncipe, 1,200 trees were recorded, 110 different species observed, and 450 herbarium samples were collected for further investigation. Our work to better understand Príncipe’s trees – from their distribution across the island to how they are used by local people – enables informed decision-making about how best to conserve them.


FFI and its three local partners are currently engaging with local stakeholders to establish more sustainable marine resource use practices around the islands. This work includes consultations with local communities as part of the marine spatial planning process, as well as engagement with the national government.
