The regeneration of Douglas fir, Pseudotsuga taxifolia Britt in the New Forest



The regeneration of Douglas fir, Pseudotsuga taxifolia Britt in the New Forest



Journal of Ecology 33(1): 44-56



The condition and progress of the regeneration of Douglas Fir (Pseudotsuga taxifolia) in the New Forest were studied during 1941-43 in Buskett's Lawn Enclosure, which was made in 1864 and planted shortly afterwards. Entry of new seedlings into the crop is erratic, and this appears to be due to erratic seed production. Establishment in the area studied seems to be largely determined by the presence of a carpet of coniferous litter, deciduous litter providing unsuitable conditions. Bare mineral soil is also suitable. In the Pine and the Pine/Oak crop, a carpet of bare litter or litter with moss and little higher vegetation seems to be necessary. When the canopy becomes sufficiently open to permit Douglas Fir establishment, other vascular plants also begin to invade, and in a few years further entry of Douglas Fir becomes impossible. There will thus be a limited period in the development of the crop when a hitherto dense canopy is beginning to open, during which conditions for regeneration are very favourable. In the absence of canopy, open vegetation with much litter and moss also appear to be necessary, and coincidence of a good seed year with the year of felling would apparently be needed to give a good stocking of young Douglas Fir. In shade tolerance in youth, Douglas Fir exceeds most British species except Fagus. In rate of growth, on suitable soils, it is comparable, when young, with Sycamore and Birch, and this high rate is maintained longer, so that at the age of 80 it is usually much taller than any British tree at maturity. These traits, coupled with its ability to regenerate on an organic substratum, appear to fit it for the role of a climax dominant. If, however, its behaviour in the New Forest is characteristic, it would only be able to enter British woodland freely under the rather special conditions provided by the floor of a conifer crop or by the clearance of vegetation by felling, burning, etc.
