Ecology

Since the canal was first opened in 1798 it has naturalised, providing an important green and wetland corridor through this largely arable landscape. Two Sites of Special Scientific Interest (SSSI) and Muston Meadows Nature Reserve, are linked by the canal. Disused railway lines, intersecting with the canal add to these all important linear highways allowing species to travel around the Vale.

The canal has fallen into dereliction since its closure in1936. This dereliction was further accelerated following the 1968 Transport Act; taking away the obligation of its owners to maintain a reasonable depth of water.

Today, much of the canal is choked with weed and reeds; sometimes, with only a few inches of water. Inaction, will, through natural progression, eventually result in the waterway becoming dry land. The canal’s future depends upon restoration.

Restoration to navigable standards will ensure a good depth of oxygenated water throughout. It is the aim, as these works progress, to enhance the ecology of the canal. The Grantham Canal Society(GCS) drives this restoration, working closely with predominant owners; the Canal and River Trust, along with valuable input from the Trust’s ecologists.

Long reaches of clear water are a necessity for insect eating birds; Swallows, Martins and Swifts. Species of bats, such as Daubentons, also need to skim the surface for insects. Not forgetting Kingfishers, needing to see their prey!

Lush marginal vegetation, comprising of reeds, rushes and sedges, provide habitat for Reed and Sedge Warblers. Emergent vegetation is important for dragonflies and damselflies to complete their metamorphosis into adulthood.

Yellow Iris, Flowering Rush and Water Lilies all add colour and, sadly, do invasive species such as Water Hyacinth and Water Fern.

Conservation of the built environment, along with the natural environment, is an important aspect of our work in our aim to return the canal to navigation
