The weather was set fair for another 'just past' sunrise visit to the Blaenavon Landscape. The track that led me past horse grazed fields at Garn yr erw with their eclectic mix of animal shelters and supporting bathroom clutter was lined with Hawthorn that was just coming into leaf. The trees at this altitude tend to be several weeks behind their lowland counterparts when it comes to leaf burst, nonetheless their fresh greenness set against the mornings blue sky was a satisfying sign that spring had now arrived.
A Chiffchaff and Green Woodpecker could be heard calling from the nearby Garn Lakes Local Nature Reserve (LNR) as I progressed around the foot of a steep coal tip and in sight of Hills Pit chimney. A male Wheatear sang strongly from the top of this conical- Madonna's bra -tip as if to assert his position as 'king of the castle'. At the chimney more Wheatear sparred for control of this elevated stone structure flying strongly between nearby fence posts and ground level exposed stonework before ceasing an opportunity to momentarily claim the chimney for themselves. It was clear that these early spring migrants had arrived in force and were keen to get on with the immediate requirement of establishing a breeding territory.
Past the chimney the terrain leveled to briefly ease the contours on the map - does anyone read maps these days? Here a number of former industrial ponds, most still supporting open water but with others in clear need of management, are an unappreciated ecological and archaeological feature of this wonderful landscape. I was instantly greeted by the familiar vocalizations of nesting Canada geese. These loudmouth non-native invasive species are now so numerous that paired birds claim ownership to what seems to be sub-optimal habitat in which to raise a brood. Birds not only called loudly from the immediate vicinity but others could be heard from out of sight locations throughout this wetland landscape. Birds that were visible were often encountered grazing sheep-like on vegetated coal spoil tips.
The small number of trees around these ponds are mostly Hawthorn and Goat Willow but are punctuated by several stunted, weather beaten and decaying Crab Apple trees that are clearly a remnant of historical boundary planting. Whilst the pragmatic side of me claim them to be native Crab Apples I hold on to a romantic notion that they could be a rare or long lost breed of native apple and if so will be in urgent need of conservation. I've tried to match the fruit with others online but this has just led me up the garden path to a position of frustration and hopeless resignation that I'll never confidently identify this apple without specialist intervention.
I searched the still largely leafless trees for territory claiming birds. Skylark sang heartily high against the strong raising sun as I picked out a pair of Reed Bunting low down in a willow tree, and further on a pair of Stonechat one of four pairs encountered on this visit. The female had turned her back on me whilst the resplendent black, red and white male stood proudly at treetop occasionally knocking together those pebbles to let me know he was there. A single Linnet flew strongly overhead before I flushed a Snipe from the confines of a stand of Purple Moor Grass.
Further on two medium sized ponds were my focus of attention. Once again these former industrial ponds that last year supported breeding Tufted Duck as well as Common Toad and a typical yet notable community of upland odonata, were now occupied by Canada Geese. Recent work on the lower pond to re-establish a water management regime to help control water levels to moderate flood risk and enhance habitat was refreshing to see. This simple yet cost effective intervention will have wide ranging and long lasting sustainability benefits. Well done to all involved! More please!
