The Canary Islands are intensifying efforts to protect the unique native flora within Timanfaya National Park in 2025. These ongoing initiatives include surveillance, landscape restoration, and targeted control of invasive species.
A primary focus is on managing the 'calcosa' plant (Rumex lunaria), which, although native to the Canary Islands, was introduced to Lanzarote in the 1930s for forage and has since become invasive within the park. Researchers are exploring biological control methods, such as using a local fungus (Septoria sp.), to inhibit its germination without harming other plant species. Citizens are also contributing by reporting invasive species through the RedEXOS app.
Experts emphasize the importance of preserving native flora along roadsides to prevent the spread of invasive species. They also highlight the significant threat these species pose to global biodiversity, particularly on islands like the Canaries. Maintaining the native flora on the edges of the roads and not eliminating it is essential to prevent the spread of invasive species.
Climate change and invasive species are major threats to Canary Island flora. Prevention, coordination, and environmental education are crucial for protecting the region's biodiversity. The Ministry of Ecological Transition of the Canary Islands Government attributes this achievement to twenty years of surveillance and landscape restoration.
