Scrub encroachment and its effects on soil fertility on Newborough Warren, Anglesey, Wales

摘要: Abstract Scrub species have colonised the dune system of Newborough Warren, apparently since myxomatosis wiped out its rabbit population in 1954. The colonisation by hawthorn, most abundant scrub species, and effects on soil fertility were studied. Measurements made along four transects showed that 95% hawthorn has myxomatosis, there is a decline average age density bushes towards sea not accounted for unfavourable growing conditions but rather slow rate colonisation. There evidence enrichment topsoil nitrogen phosphorus occuring beneath bushes, indications are certain nutrient-demanding weedy typical would replace dead dushes. Sparse widespread individuals Pinus from adjacent forest. Without appropriate management, pine could become abundant.
