Status: Site of Nature Conservation Importance (Lincolnshire Trust)
This site is composed of a narrow (1-2m) drain which runs alongside the River Witham,
together
with an area of adjacent rough grassland and tall herbage. The site has been designated as Critical
Natural Asset for the following reasons:
1) The site is one of 13 wetland sites in Lincoln. The site has an assemblage of aquatic
species
that suggest little or no pollution. The site is one of eleven in Lincoln supporting unimproved/semi-
improved neutral grassland habitat. Given the linear nature of the site its total area as well as that
of its habitats is unknown. The current extent of un- and semi- improved grassland older than five
years in Lincolnshire is 48,860ha (est.), a loss since 1938 of 74%.
2) The site is part of the Witham Valley Green Wedge and is an important component
in the
complex of wetland sites within the Witham Valley.
3) The site supports the following rare and endangered species:
Trifid bur-marigold Bidens tripartite
The bur-marigolds are plants of lake and pond margins, ditch and stream sides. The
species has
decreased nationally and severely so in Lincolnshire where it was formally localised but
widespread. It has declined in Lincolnshire from fourteen sites in 1988 to just three in 1995 (two of
which are in Lincoln).
Landscape Value
Linear water feature which adds to the diversity and interest of the landscape within
the proposed
Witham Valley Green Wedge and to the enjoyment of the riverside footpaths by the public for
informal recreation.
