The UK's seas support a variety of life as fascinating and colourful as that found anywhere in the world. This seemingly inhospitable environment (for humans) is home to over 8,000 species and yet we know as little about much of it as we do about the moon.

Consequently, protection for marine habitats and species has lagged behind that of terrestrial landscapes and wildlife. Man's activities are wreaking damage on a huge scale. Through surveys, awareness and education and policy development the MCS Biodiversity programme aims to ensure that marine species and habitats are given protection before its too late.

The programme includes the study of rare yet important species such as the pink sea fan and fan shell; actions to support the UK Biodiversity Action Plans for marine species and habitats; the promotion of a network of marine protected areas to safeguard nationally important hotspots for marine life; and the prevention of potentially devastating events such as alien species invasions.
