DNA Testing Aids Project to Restore Rare Black Poplar Trees

A project focused on restoring the UK's rare black poplar trees is underway in the Thames Valley, employing DNA testing to aid regeneration efforts along the River Thames and its flood plain. Conservation groups have issued warnings regarding the significant decline in black poplar numbers, attributing the loss to decades of felling, land drainage, and habitat destruction.

The "Swindon to Oxford: Regenerating the Thames and Tributaries" nature recovery programme is collaborating with local conservation groups to bolster the tree population. Catrina Bass of the Long Mead Foundation in Swindon noted that despite the black poplar's resilience, only about 50 individuals are currently recorded in Oxfordshire.

Described by Bass as having "great gnarled trunks" and resembling trees from "Lord of the Rings," the black poplar is a vital species that supports other wildlife, including the poplar hornet moth. The initiative received initial funding from West Oxfordshire District Council and the Vale of White Horse Council and is now seeking to raise an additional £20,000.

Funds will support crucial work, including DNA analysis of existing trees, propagation of new cuttings, and planting in suitable locations. Oxfordshire County Council's Local Nature Recovery Strategy has pledged to match fund the fundraiser up to £10,000. The Trust for Oxfordshire's Environment, an organization that assists community groups in funding local environmental projects, is also participating.

Benjamin Heaven Taylor, chief executive of the Trust for Oxfordshire's Environment, highlighted the black poplar's role in flood risk reduction, as the trees lining rivers and floodplains help retain water. He described the remaining population as "extremely fragmented" and in need of significant support for recovery.
