What is The response of male and female black poplar (Populus nigra L. subspeciesbetulifolia (Pursh) W. Wettst.) cuttings to different water table depths and sediment types: implications for flow management and river corridor biodiversity about?

Management of river ̄ows has altered the pattern of ̄ood arrival times and reduced their frequency and duration on many European ̄oodplains. Floodplain tree species depend on ̄oods both to provide new sites for their regeneration and to recharge water tables at various depths in the rooting zone. A reduction in ̄oods is one factor that has led to loss of river corridor biodiversity, with early successional tree species from the Salicaceae being particularly adversely aected. Members of the Salicaceae are dioecious and it is possible that the males and females of these species have measurably dierent water table requirements, which might lead to spatial segregation of the sexes on a ̄oodplain. This paper describes an investigation that was carried out into the response of male and female black poplar (Populus nigra L. subspecies betulifolia (Pursh) W. Wettst.) to dierent soil moisture conditions. An experiment was set up on an alluvial island in the River Great Ouse (UK) in which cuttings of male and female black poplar were grown in dierent sediment types with dierent water table levels. The experiment was carried out over two ®eld seasons in 1997 and 1998. Results showed tha
