Why these species?
Almost 80% of Cape Verde’s 92 endemic plants are threatened with extinction. This includes the Endangered phoenix palm Phoenix atlantica and iron tree Sideroxylon marginatum and a Critically Endangered endemic sub-species of dragon tree Dracaena draco caboverdeana. All three of these trees are found on Brava, the most remote and, consequently, one of the most untouched of Cape Verde’s islands.
At 64 km2, Brava is the smallest inhabited island in the archipelago. While it has not faced the same levels of tourism development and desertification as the rest of Cape Verde, the fate of its flora remains highly uncertain. It has no official protected areas, its three threatened tree species are all exploited (leaves and fruit from the palm, timber from the iron tree and resin from the dragon tree) and they, and the rest of the island’s unique flora, face grazing pressure from goats. Invasive species cover large areas of the island and there is evidence of hybridisation between a non-native palm and the endemic phoenix palm, which could lead to a loss of valuable genetic resources in the future.
What are we doing about it?
In partnership with local conservation organisation Biflores, we are working to better understand and manage the main threats to Brava’s threatened trees. Our work includes:
- Where invasive species are smothering or outcompeting individual trees, we are removing the invasive species and, where possible, planting an endemic tree in its place.
- We aim to improve natural regeneration by working with livestock owners to develop sustainable grazing management plans and by installing fencing around the most threatened trees.
- Through outreach efforts with local stakeholders, we seek to boost the profile of these special trees within local communities and encourage people to take action to conserve them.
A scoping project in 2018-19 provided crucial data about the distribution of the three species. Across the island, 401 target trees were recorded: 84 of which are phoenix palm, 127 are the Cape Verdean dragon tree and 190 are the iron tree. Armed with this information, we can now prioritise our efforts to protect the most important areas for each species.
