Aliens to the Rescue?

With the exception of one species on Orme's Head in North Wales, Cotoneasters are introduced, ornamental, evergreen shrubs. They can go 'wild' in some locations such as former quarries on the Island of Portland (Dorset). The Royal Horticultural Society (RHS) found that one hairy-leaved species, Cotoneaster franchetii, is 20% better at absorbing air pollution than any other tested hedging species e.g. Hawthorn (https://www.theguardian.com/environment/2021/feb/18/experts-identify-super-plant-that-absorbs-roadside-air-pollution). The RHS consequently recommend planting hedges of this shrub, alongside busy roads. This seems a useful and, not unattractive, aid (just don't let it run too wild).
