Living Levels 99 Part One – The Scheme Plan / Statement of Significance A Wildlife Oasis The Living Levels study area is a complex landscape. Reclaimed from the sea, its reliance on and relationship with people is precarious, intricate and yet enduring. Nature, for its part, has exploited the opportunity and created a unique ecosystem – an ‘accidental’ oasis supported by the special way the Levels has been created and managed.
