Gadwall and Little Grebe

This April photograph shows just how delayed the vegetation is this year. Pussy willow was amongst the few seasonal flowering plants this weekend. The water levels are holding well and the filter beds are filling up with water. 







This means that the duck are returning, and a pair of gadwall and little grebe were present, along with resident coots and tufties. There are no sand martins or swallows in our area just yet, but these can be expected any day.

After the reservoir was made redundant in the 1960’s, housing was planned for the site, but was fiercely opposed by local residents at several public inquiries.

The council purchased the reservoir in the 1970’s and it was managed as a public space until the 1990’s, when it was designated as a Local Nature Reserve. A boundary line of imposing hybrid black poplar trees are thought to be about 170 years old and bat boxes have been erected at a height suitable for noctule bats, which are regularly recorded there along with Pipistrelles and Daubenton’s bats.
