DESCRIPTION:This talk is part of the AGM of the Friends of the Roman Road 
 and Fleam Dyke.  Professor Grubb is our Patron. Chalk grassland is now an 
 endangered habitat in Cambridge because so many such areas were cleared as
  sheep grazing gave way to arable farming. The three Linear Sites: the Dev
 il's Ditch or Dyke\, the Fleam Dyke and the Roman Road are best surviving 
 examples of this sort of habitat\, but they have all suffered from scrub o
 vergrowth. There has been a tendency to clear scrub in the hope of restori
 ng the lost flora. This continues despite a great deal of research work by
  Peter Grubb in the l970s demonstrating the failure of this approach. In t
 his talk he will explain the nature of the problem and why simple clearanc
 e will not work.
