Grantham Canal (Long Clawson to Harby)

Wildlife Highlights

The Canal comprises sections of dense reedbeds (Phragmites) whilst Bulrush, Yellow Iris and Branched Bur-reed are also widespread, together with Lesser Water Parsnip and Flowering Rush along the more open-water stretches. The Canal banks are covered in Meadowsweet and Willowherb whilst the hedges along the towpath are predominantly Hawthorn and Blackthorn. The main trees flanking the canal and towpath include Ash, Weeping and White Willow, Osier, Sycamore, Alder, Pendunculate (English) Oak. Elder and Wych Elm

Some sections are well stocked with fish, with Pike often seen.

In addition to the resident breeding waterbirds (Mute Swan, Mallard, Moorhen and Coot), in summer there are good populations of warblers, the commonest include Reed, Sedge and Willow Warbler, Blackcap, Whitethroat and Chiffchaff. Swallows, House Martins and Swifts are regularly seen along the Canal in the summer months. Kestrels and Buzzards are  frequent, and Kingfisher and Grey Heron occur, but are easily flushed when disturbed. In winter our resident thrushes are augmented by large, highly mobile, flocks of Fieldfare and Redwing, and in adjacent ploughed fields flocks of Lesser Black-backed Gull and Black-headed Gull are often present.

The common species of butterflies in the East Midlands are all well represented with flight periods beyween March to October. Eighteeen species of dragonfly and damselfly have been recorded along this stretch including the Hairy Dragonfly and Variable Damselfly, both are close to the limit of their range that lies mainly in SE England. Sightings of Emerald Damselfly and Banded Demoiselle are now rare.

Description

This western part of the Grantham Canal in Leics stretches 2.5 miles from the county boundary at the River Smite aqueduct north of Long Clawson, eastwards past Hose, to Harby. The Grantham Canal was built to supply coal to Grantham and runs from the River Trent in Nottingham for 33 miles to Grantham. The Canal was opened in 1797 and closed to traffic in 1929. After several decades of public ownership the canal management passed from British Waterways to the newly formed Canal and River Trust in 2012.
