Moluscs, Reptiles and Amphibians


The molluscs have been extensively surveyed by M Hughes (1978). North Meadow is fairly rich in calcium carbonate, an important point in that the amount of available CaCO3 is a direct factor in species determining the presence and abundance of many gastropods. Forty-one species of mollusc have been recorded on the reserve, and are found in three distinct habitats, the rivers, drainage ditches and on the meadow itself.

The most commonly occurring freshwater gastropods appear to be ram’s horn snails, White Ramshorn snail, Faucet snail, Great pond snail and Marsh Snail.

The most abundant terrestrial gastropods are vineyard snail, amber snails, and the glass snails. Amongst the bivalves, the fingernail clams and the river mussels are thought to be the most abundant.


The grass snake, the only reptile recorded, can be found both near the water courses and in the long grasses.


Frogs are not uncommon and spawn is found in the north-eastern boundary ditch most years. Toads are much less common, and the smooth newt has been recorded once.
