Those 'not for profit' grey suits at Dwr Cymru/Welsh Water really did pull a rabbit out of the hat when they rebranded Llandegfedd Reservoir as a lake. There's possibly a trades description issue here because a lake is a waterbody formed by natural processes, but by contrast Llandegfedd is a reservoir created by the deliberate flooding of a valley with water retained by a bloody big concrete dam. It reminds me of the legal fiascos around whether a Jaffa Cake is an actual cake and more recently that involving oat milk.
Having not visited Llandegfedd Reservoir for a little while, I was struck by how much the site had changed and how very difficult it is now to do any decent birding. The biggest spanner in the works is the development of extensive willow scrub around the margins of the North Car Park and The Island. At one time the scrub was restricted to the upper reaches of the drawdown zone or shoreline, nowadays its taken hold within the drawdown zone and as such, and in my opinion, requires some urgent management attention from Welsh Water.
We mustn't forget one of the reservoirs notifying features as a Site of Special Scientific Interest (SSSI) is that of wintering Wigeon. Historically these birds were present in their hundreds grazing in the meadows that border the reservoir with some even spilling over onto neighboring farmland. Its true that with the milder winters its become less necessary for them to move westwards in substantial numbers, but its also the case that Llandegfedd Reservoir has become less appealing for these birds. Access to grazing meadows is denied by a ring of aforementioned scrub and some of the adjacent farmland is now a golf course with year round disturbance including stray balls that pock mark the exposed mud of Green Pool. All of which has taken place under the sleepiness of Natural Resources Wales (NRW), who's apparent keenness to embrace Welsh Water's new found 'not for profit' development of recreation facilities seem to have forgotten that this reservoir is a SSSI and with it comes legal obligations.
And then there's the dwindling birding community. Once this reservoir was the most significant inland waterbody for birders. Pick up any Gwent Bird Report from the 1970's onward and Llandegfedd will feature front and centre of the systematic list highlighted with tables of year round wildfowl counts. Nowadays this detail is patchy. Wildfowl counts are seemingly inconsistent and birding information from the small number of birders who do visit the site scattered across various social media platforms or hidden behind elitist invitation only groups. The availability of consistent time-series data of trends is critical to challenge any future push by Dwr Cymru/Welsh Water to convince NRW to de-notify the reservoir as a SSSI. However, and unfortunately, this drift towards the fragmentation of ornithological data could unwittingly aid Dwr Cymru/Welsh Water should a challenge ever arise. Evidence is the key and its only birders who can provide this. If they feel less inclined to follow the traditional route of submitting records to the annual Gwent bird report then they should at least send records to the South East Wales Biodiversity Records Centre (SEWBReC). Birding must be based on a conservation ethic so in my opinion there's a moral obligation to submit records and to make them count!
