Project to restore rare native trees with DNA testing

1 day ago

A conservation initiative is utilizing DNA analysis to help restore one of the United Kingdom's rarest native trees across the Thames Valley, following long-term declines in its numbers.

Environmental organizations have warned that the native black poplar population has plummeted as a result of decades of logging, land drainage, and habitat loss. In response, the Swindon to Oxford: Regenerating the Thames and Tributaries nature recovery programme is partnering with local conservation groups to boost tree populations along the River Thames and its surrounding floodplain.

Catrina Bass, from the Swindon-based Long Mead Foundation, is participating in the project. She noted that while black poplars are "extraordinary survivors," just 50 of the trees are currently recorded in Oxfordshire. Describing them as "Lord of the Rings" looking trees with "great gnarled trunks," she highlighted their role in supporting local wildlife, including the poplar hornet moth.

The initiative initially received funding from West Oxfordshire District Council and the Vale of White Horse Council. Organizers are now aiming to raise £20,000 to carry out DNA testing on existing trees, propagate new cuttings, and plant them in suitable locations. Oxfordshire County Council's Local Nature Recovery Strategy has pledged to match donations up to £10,000.

Also involved in the effort is the Trust for Oxfordshire's Environment, which collaborates with community groups to fund local environmental projects. Chief executive Benjamin Heaven Taylor explained that black poplars play a vital role in reducing flood risk by lining riverbanks and floodplains to hold water back. He noted that the surviving population is "extremely fragmented" and "needs a helping hand to recover."
