Today, the Kerkennahs are facing the challenge of preserving their cultural and environmental heritage. If not valued, the island craftsmanship, especially the construction of Kerkennian feluccas, tends to disappear.
Biodiversity is moreover put under pressure by the loss of Posidonia meadows. Overfishing, the use of prohibited gear, and trawling are undermining the marine environment by tearing away seagrass and by fishing non-targeted species (such as turtles). Pollution and invasive species represent additional pressures for the environment. These practices, accompanied by dragging at sea and gas prospecting, reinforce the erosion of the coast and threaten the archipelago. Many wetlands areas are shrinking. Plant species are locally declining and animal species, particularly birds, are probably less present (non-existent monitoring programs).
Some areas are distorted by waste deposits, construction debris, or wastewater and rainwater spillage. The issue of fishing waste (nets, traps, cans, waste oils …) remains a major challenge in the inhabited and coastal areas.
