OIL IMPACTS Mangroves are highly sensitive to oil exposure. Diverting water can harm mangroves by preventing their seeds from being dispersed via seawater, and it can kill the trees by cutting off freshwater supplies. The Australian population has a love affair with the coast; some 85% of all Australians live within 50kms of the coastline. Mangrove roots (pneumatophores) are sensitive to trampling, and the mangrove wildlife, particular breeding birds, are prone to disturbance. With his ENST scientific diving experience he hopes to move on to a career focused on policy and natural resource management. The Mangroves: Field Study.
