Conference Report - 2009 - BSBI Spring Conference on alien trees and shrubs, Berwick 59 CONFERENCE REPORT BSBI Spring Conference on alien trees and shrubs, Berwick-upon Tweed, 9 th - 11th May Rarely has a BSBI meeting been held in such a grand setting. With chandeliers glittering overhead in the Guild Hall the President, Michael Braithwaite, welcomed 86 members and guests from several local societies and remarked on the excellent turnout. After a brief commentary on George Johnston, a former Mayor of Berwick and founder of the Berwick Naturalists' Club in 1831, he handed over to Jane Croft, BSBI Vice-president and chair of the morning session. She introduced the first speaker, Jeremy Ison, who confessed that, although a member for over 30 years, this was the first time he had assisted the BSBI on a specific project - a BSBI report on The status of some alien trees and shrubs in Britain. The uneven treatment of alien taxa in the New atlas had prompted the sending of a questionnaire over the winter period to all vice-county recorders asking for such information as: which alien trees and shrubs were becoming naturalised (not just planted), what habitats were being colonised by naturalising species, and for any changes in patterns of planting. Results were received from 48 vice-counties and ofthe 148 taxa included in the survey, 112 were reported to be naturalised somewhere, and all had regenerated somewhere to some extent whether vegetatively or by seed. Amongst the problems, it was noted that Picea sitchensis (Sitka Spruce) was widely recorded as having a 'weedy' tendency, frequently colonising moorland habitats. Pinus contorta (Lodgepole Pine) regenerated well in wetter vice-counties. Quercus cerris (Turkey Oak) and Q. ilex (Holm Oak) were both reported to be spreading into lowland heaths in south-west England. Pseudotsuga menziesii (Douglas Fir) was regenerating well and becoming naturalised in many southern vice-counties. GWYNN ELLlS & MICHAEL BRAITHW AITE Biomass plantings were not well recorded, due to the difficulties in visiting sites and in determining which taxa are involved in the Salix hybrid plantations. The species most widely reported as regenerating were similar to those most widely reported as naturalised, with the addition of three of the species that spread vegetatively to form large patches: Fallopia japonica (Japanese Knotweed), F. sachalinensis (Sachalin Knotweed) and Spiraea agg. One of the main aims of the survey was to stimulate the study of regeneration of alien trees and shrubs and it is hoped that this is indeed the case. The next speaker was Maggie Magee, formerly of FW AG, but newly self-employed as a consultant, who gave a fascinating talk on species selection and sourcing for farm woodlands. Farmers have long relied on native woodlands as a source of timber for fencing and buildings, but only where grazing pressure has been greatest have they needed to look at re-planting woodland - Elm, Ash and Holly are all readily eaten by sheep. In the nineteenth century new species of tree were introduced from foreign parts and many of these were planted by owners of great estates and became the mainstay of planted trees in woodland. We now have semi-natural woodlands and plantations. Some of the trees planted were at the whim of the forester in charge at the time. Blocks of conifers were planted as shelter-belts, often monocultures of Sitka Spruce or larches, with (occasionally) some broad-leaved trees at the margins. Today, species choice is important, but so is proper management - woodland needs to be thinned if an economic timber crop is to be the end product. A woodland of native species needs to be planted at random, with Birch, Hazel and Blackthorn, for example, with no
