Put simply, trees cannot grow as much in heavy seed years as they do in other years, and in many species, the seed crop of one year negatively affects the seed crop of the following year. Helicopter Seeds. Sycamore was added as a tenth species for structural surveys but was not included in the seed dispersal survey because of timing of dispersal.
