Sites (approx.): 80ha in 10 sites.
Water courses (such as the Delph Drains), lakes (such as Starmer's Pit), large ponds
(such as
Blue Lagoon) and their associated aquatic habitats are notable features of Lincoln's "downhill"
landscape. Originally Lincoln possessed a great wealth of fenland habitat, for example on the
Pyewipe and Washingborough Fens; apart from fragments in sites such as the Witham Marshes
this habitat has now largely vanished. Gravel and ballast pits (such as the Trust's Boultham Mere
reserve) are a vital element in redressing the loss of ancient wetlands through careful restoration
and aftercare schemes.
