Maiden Erlegh Reserve – 14 April 2018

Following a week of unremitting cold and rain, the warm sunshine on the afternoon of Saturday 14 April, when Renée Grayer led a walk at Maiden Erlegh local nature reserve, was a welcome change. While the group were gathering at Instow Road, Brimstone, Comma and Small Tortoiseshell butterflies were seen and Peacock was soon added to the tally. A number of native species have been planted around the reserve, and specimens seen in the garden of the Interpretation Centre included the leaves of Shining Cranesbill and flowering Cuckooflower. The walk started out through Old Pond Copse, the strip of woodland in the valley of the stream which flows out below Maiden Erlegh Lake. The rich ground flora indicates that this is ancient woodland and flowers included Primrose, Common Dog-violet, Wood Anemone, Wood-sorrel and Wood Spurge. The first Bluebells were just coming into flower. Leaves of Wood Speedwell, Three-nerved Sandwort and Ramsons were also noted. The small yellow flowers of Opposite-leaved Golden-saxifrage were found in the wetter parts of the wood, together with Marsh-marigold. The leaves of Hemlock Water-dropwort, Fringecups and Wild Angelica were seen by the stream. In a pond in the valley bottom were several clumps of Summer Snowflake. It was suggested that these might be the wild Loddon Lily, but closer inspection of the stem edges revealed that they were smooth, as in the garden plant, rather than with the minute teeth of the wild plant. Chiffchaffs, Blackcaps, Nuthatches and a Green Woodpecker called and two Buzzards soared overhead. After walking through Old Pond Copse and Moor Copse, the route led back to Maiden Erlegh Lake and through Oak Wood on the south shore. Moorhen, Coot and Great Crested Grebe were amongst the sightings on the lake, while a Grey Heron perched in a tree above the water. A bank of sunny Blackthorn blossom at the end of the lake proved a magnet for butterflies, with several more Peacocks and Commas and a newly-emerged Holly Blue. Finally, in a nettle patch by the road, a tiny 24-spot Ladybird was seen on a sunny nettle leaf, with a much larger 7-spot Ladybird nearby for comparison.
