Birds of the Corran
As swallows gather on wires and the joyful trilling of greenfinches continues unabated, it really isa good time to count our blessings. This spring and summer, with the help of the excellentMerlin app, I’ve been counting birds. This has resulted in large spreadsheets indicating what’s been ‘heard’ by Merlin and seen/heardby me. I take our old dog for a slow walk or my daughter’s much sprightlier hound for a longerone. Either way, I’ve been spending more than an hour a day on

Fond climates and sweet singers
Travels with my App - up and down The Lane (Horsepool Road) - continue as the seasons turn. A too-mild start to the month soon gives way to spells of finger-numbing cold, mist, some hard rain, named storms and lots of Welsh sunshine, commonly known elsewhere as: drizzle. October starts with a final flourish of swallows and house martins. Gone too are the whitethroats and flycatchers. There are far fewer flies but the wasps persist. Fewer flowers too, barring some late-bloomin

Water testing results for the River Corran and Mackerel Lake Stream. October 2026
Here is our monthly water report update from the Laugharne Citizen Science Group for October 2026! By comparing October’s results against our year-round data, we get a clear picture of how autumn rain, agricultural run-off, and seasonal changes are impacting our aquatic ecosystems. River Coran (Abercorran to Newbridge) The overall picture along the main part of the River Coran this October shows stable water clarity, good oxygenation, and a welcome recovery in pH levels, but

The surprise of our life on Mackerel Lake stream!
The third location for our invertebrate sampling is Mackerel Lake stream, a section upstream from the culvert on The Lacques. At first sight this did not look a promising location to find invertebrates, the flow was slow, the water level low and there were long sections choked with water weeds such as dropwort, figwort and watercress, amongst others, as well as being overgrown with brambles. Our little band of volunteers braved the thorns and risk of entanglement to enter any

Laugharne Estuary Comprehensive September 2026 Water Quality & Incident Report
Monitoring during September 2026 revealed an event across the Laugharne Estuary, reversing August’s clean baseline. Initial testing on 18 September recorded a Phosphate surge (1.34 mg/L) and an acidic drop in marine pH (6.9). Targeted re-testing on 21September at 15:30 recorded an Ammonia spike of 1.64 mg/L at Frog Rock (SN 30516 10348,~40m from the STW outfall). We have asked NRW and Dwr Cymru to investigate. Key Findings from 21 September 2026 Follow-Up Acute Ammonia Spike

Counting Birds of the Corran Exploring Our Local Wildlife Through Citizen Science
Spring and summer bring a lively chorus of bird songs and the flutter of wings along the River Corran. This season, I have been using the Merlin app to track and identify birds during daily walks on Horsepool Road, a path that follows the upper reaches of the river. These walks, whether short with our older dog or longer with my daughter’s energetic hound, have opened a window into the rich variety of birdlife in this area. The experience has been rewarding, revealing both th

Pendine Bathing Water — 2025 Season Report
Found this on the NRW dataset site. I have added their widget to the site here . The 2026 report/figures should be out mid November. From this dataset, ranking the 78 EXCELLENT-rated beaches by their combined bacterial levels (95th-percentile E. coli + intestinal enterococci — lower is cleaner), the five cleanest in Wales for the 2025 season are: Freshwater West (Pembrokeshire) — E. coli 11.8, IE 11.8 Marloes Sands (Pembrokeshire) — E. coli 11.8, IE 12.8 Lydstep (Pembrokeshir

Life in our river-2
Once again, our intrepid volunteers placed themselves on the riverbank and in the river at the Kiln Lane location – many thanks to Jenny for the use of her garden. With a group of six, a portable table, and some hard-won experience under our belts, both sampling and counting was much easier and quicker than our first foray. The weather was calm and sunny, which made for a pleasant time overlooking the fields from under the shade of the trees. Also, despite the very long dry s

Welsh Water Storm Overflow events
Welsh water have a storm flow map which is updated daily on releases. I have started monitoring these releases to try and work out the pattern- if there is one. And why they happen- given no storms for the last 3 months. This is a image of the area where welsh water have works or storm overflows in the area which ends up in the Taf and so the estuary. The paler symbol in the above screen grab is a overflow that has released in the last 24 hours. I will update the spreadsheet
