Species Lists

 A botanical survey was made by the late Eric Smith and described in his account ‘The Botany of Nailsea’ in 1983. He said -
“A mass of Ragged Robin (Lychnis flos-cuculi) grows near the pool; a grass, Water Whorl Grass (Catabrosa aquatica) and Great Pond Sedge, also Distant Flowered Sedge (Carex remota). In the water here, two pondweeds (Potamogeton natans and P. compressus) and Canadian Pondweed (Elodea canadensis) grow. A plant of Hemlock (Conium maculatum) grew several years ago near the footbridge leading to Stone-edge Batch and Brookweed (Samolus valerana) was seen in the stream between the track from Pound Lane and Moorend Spout.”

Sadly some of the plants that he recorded seemed to have been lost. We were unable to find Ragged Robin (Lychnis flos-cuculi) but we have now reintroduced this. Moreover, the Southern Marsh Orchid (Dactylorhiza praetermissa) has not been seen recently. However, about two years ago an orchid (not fully identified, but possibly the Early Marsh Orchid (Dactylorhiza incarnata), since the flowers were very pale, was found in the centre of the site. Lesser Water Parsnip (Berula erecta) and Water Figwort (Scrophularia auriculata) are still present. The marshy area has Lesser Pond Sedge (Carex acutiformis) and the Greater Pond Sedge (Carex riparia), Brooklime (Veronica becca-bunga) and Hemlock Water Dropwort (Oenanthe crocata). The rare Slender Spike Rush (Eleocharis uniglumis, ID subject to confirmation) grows in the centre of the field and the rare grass Catabrosa aquatica was found in the rhyne adjacent to the footpath that accesses the site from Pound Lane. This was lost when the rhyne was keeched in 2011. Many wet-woodland plants grow amongst the Alder trees in the area between the two rivers and the site is particularly favorable for Willows.

A few years ago the unusual Amber Snail (Succinea putris) with an almost spherical shell was found in large numbers climbing up the vegetation in the damp areas, and the Mullein Moth (Shargacucullia verbasci) caterpillar was feeding on the Water Figwort, a close relation of the Mullein that is its more usual food plant. The Banded Demoiselle (Agrion splendens) damselflies in the rhynes are especially attractive and many butterflies can be seen here in the summer. This area could be expected to support Otters and we have found spraint on the stone bridge.
 It seems likely that there are American Mink and these aggressive predators could prevent the establishment of Water Voles. The river has Signal Crayfish, and Three-spined Sticklebacks. 

The following species have been observed at Moorend Spout. Initial surveys were undertaken in 2010, and we also undertook a Bio-Blitz on the site in July 2013.

Our most recent survey results, from a one day survey in July 2017, are here.

Hemiptera heteroptera (2013)

 Latin name
Common name
 Meadow plant bug  
 Stenodems calcarata  A grass bug  
 Arthaldeus pascuellus  Halberd leaf-hopper  
 Arthaldeus striifrons  Tall fescue leaf-hopper  
 Conomelus anceps  Common Sand Couch Spur-hopper  On rushes
 Eupteryx aurata  Golden Leaf-hopper             On stinging nettles

 Macrosteles sexnotatus  Meadow Migrant leaf-hopper there is some controversy in this because only a female was found and details of male genitalia only are reliable; however this female was outside
the size range for M. sexnotatus and within the M. cristatus size range. The latter is more frequent on cereal crops such as
oats. Further sampling is required to find males of these species at this site. One further problem is that the translation of the German trivial name is ‘Comb Migrant leaf-hopper’, which hardly seems relevant to its habit
 Philaenus spumarius   Froghopper  Also called ‘Spittle bug’
