It is with deep regret that we have to report the passing of Anthony (Tony) Jenkins last autumn. He had been a Llanelli Naturalists’ member for many years and sadly died suddenly whilst in the field, carrying out voluntary bird‐ringing work at the Welsh Wetlands Centre Penclacwydd. He was 70 years old.

Tony was brought up and educated in Llanelli and was a graduate of UCW Aberystwyth. He worked for most of his life in the Welsh Water Authority where he gained the reputation of being one of the foremost authorities on Freshwater invertebrate species, notably caddis. He was lead biologist in two separate research projects which investigated the effects of acid precipitation on the upper River Tywi catchment, together with Llyn Berwyn and Llyn Hir which resulted in a predictive method for assessing acidification based on macro‐invertebrate assemblages. He was also involved in a major study during this period into changes to the ecology of Llyn Berwyn and Llyn Hir following liming operations during which he developed specialist taxonomic skills in the identification of chironomid larvae. After leaving the NRA he became head biologist at Biopharm (UK) Ltd, being responsible for the commercial breeding aspects of the medicinal leech, which is used in certain clinical operations. From 1992 to his retirement in 2001, he became Team Leader at the Countryside Council for Wales in Swansea. His work colleagues will remember him not only for his vast depth of knowledge on freshwater biology but for his helpful, caring and cheerful manner in the workplace.

He will also be remembered for his second love – that of birdwatching. He had wide experience of ornithology, was an active bird watcher and bird ringer, and ran a nestbox scheme at Gelli Aur Country Park from 1984, with particular reference to Pied Flycatcher populations. This was featured on both radio and television programmes. He also ran a nestbox scheme at Penclacwydd with special reference to House sparrow populations.

For several years his son Richard, lived in Madagascar where he was carrying out research into aspects of the country’s threatened wildlife. This gave Tony the opportunity to visit the country several times when he took full advantage of seeing the wealth of species present there.

He will be sadly missed by his colleagues, friends and members of the Llanelli Naturalists.
