Paper abstract bibtex There is considerable interest in the need to conserve the 7000 trees which are all that remain of the population of black poplar growing in Britain. Recent work based on molecular techniques has provided markers which can unambiguously distinguish first generation hybrids of P. x euramericana from P. nigra. This is an important tool as it enables non-hybrid trees, which should be conserved, to be distinguished from exotic clones of hybrid poplars. Molecular markers have also demonstrated that the British population of black poplar has low diversity, compared with that in other European countries, and that there is a great deal of clonal duplication. Female clones are particularly rare. The ability to identify clones offers the opportunity for conservation effort to be concentrated at the level of the clone rather than that of the individual tree. Most of the British population is derived from ancestral material which colonised Britain after the last glacial period from refugia in southeastern Europe. Work aimed at understanding the physical processes which drive the ecology of floodplain forests may help to re-establish populations of black poplar which have the capacity to reproduce and adapt to a changing environment.
