(1) He started college with the intent of majoring in soil science, with minors in horticulture and arboriculture .(2) In recent years, short skills courses in arboriculture / tree surgery have been provided and these are now very popular.(3) This Part applies to arboriculture activities that involve pruning, repairing, maintaining or removing trees or cutting brush if a worker works at height and depends on the tree for support.(4) Tree surgery, a scientific process which is a part of arboriculture or urban forestry, looks at the science of developing and maintaining trees.(5) If the removal of the trees were to cause more problems, the arboriculture company should be asked to advise you how to minimise any damage.(6) The Mediterranean soils of terra rossa on a limestone bedrock are suited to extensive cereal culture and to dry arboriculture .(7) Mr Power went on to study arboriculture (the principles and practices of tree care) at Merrist Wood College.(8) So it is likely that the green cover actually came when the Government introduced arboriculture or the plantation of trees for timber.(9) A leading arboriculturist has condemned a decision to fell a beech tree which he claims is one of the best of its species in the area.(10) Harvey Lowson, City of York Council's arboricultural officer, said: ‘This hard decision has been made because the tree is in poor structural condition and is positioned over the busy public square.’(11) An arboriculturist writes: This kind of sudden proliferation is always unhealthy.(12) For 14 years he was the senior arboriculturist at the Department of Environment and advisor to central Government.(13) Simon Turner, arboricultural officer at Kennet District Council, said: ‘They have severed the roots and we are looking at measures to ensure the tree doesn't die or if it does die to get a replacement tree.’(14) The city council's leisure department, which is responsible for parks, has contacted specialists to examine the diseased trees, alongside the city's resident arboricultural officer.(15) It was subject to a condition that work be carried out between the 1st October and 31st March for the reason that it was ‘in the interests of good arboricultural practice’.(16) Replacement values typically are calculated using an arboricultural industry formula based on a particular tree's intrinsic value for size, species, and health.
