Elfi Evans lived the kind of life that makes you recalibrate what one person can actually do with their time. Born Welsh-speaking on a Carmarthenshire farm, he learned English from Italian and German POWs and American GIs during the war — a detail so perfectly odd it could only be true. He wanted to study engineering; his father pushed veterinary science. He rode a Lambretta scooter eight hours each way to Liverpool University. Everything about the origin story says: stubborn, resourceful, unsentimental. The veterinary career that followed was broad in the way rural practice demands. Evans was as comfortable with a cat as with a caesarean on a horse. His practice, The Ark, grew into a three-partner operation across Carmarthenshire. The client list eventually included an elephant named Valli, kept by the Skanda Vale religious community. He specialised in sheep diseases in the 1980s, a pivot that proved prescient when foot-and-mouth disease tore through the UK in 2001 — pulling him out of a retirement that had lasted approximately zero months. But the obituary's real weight sits in what Evans did with the land. He and his wife Ann took on a run-down smallholding near Nantycaws in the late 1980s and turned it into something closer to an ecological project than a farm. Ponds for wildlife, native tree species in traditional orchard layouts, biodiversity work supported by the Welsh government's Tir Gofal scheme. The environmental ambition was real and sustained over decades. The Christmas tree detail is the one that sticks. Evans planted non-native firs as shelter for young native saplings — a practical forestry decision. When those firs matured and were no longer needed, he harvested them and gave them away in exchange for donations to the oncology department at Carmarthen hospital, where he had been treated for cancer in the early 1990s. Tens of thousands of pounds raised, over many years, from trees that had already done their ecological job. It is an almost unreasonably efficient act of generosity. What makes this obituary worth reading — beyond the life it describes — is its structure as a portrait of competence applied across domains. Veterinary medicine, land management, conservation, community fundraising. Evans did not do these things sequentially; he ran them in parallel, each feeding the others. The smallholding supported the wildlife; the wildlife justified the government scheme; the shelter trees became the fundraising mechanism. It is a life organised like an ecosystem. The writing is by one of Evans's sons, and it has the restraint that family obituaries sometimes achieve when the writer trusts the facts to carry the weight. No inflation. No eulogy voice. Just: here is what he did, here is the order he did it in. The Lambretta. The elephant. The Christmas trees. The reader is left to do the arithmetic on what kind of person this adds up to. Elfi Evans is survived by Ann, three sons — Winston, Gavin, and the author — and eight grandchildren. He was 90.
