Item Landscape and Biodiversity Management Strategy 7.1 MANAGEMENT PRESCRIPTIONS Each of the landscape zones contain a combination of these landscape features and components; • Existing Woodland and Tree Belts • Proposed Tree Planting • Existing and Proposed Hedges • Proposed Ornamental Shrub Planting • Proposed Species-rich Grassland • Proposed Amenity Grassland • Proposed SuDS and Marginal Planting • Proposed Hard Surfaces and Footpaths 7.2 Use of Chemicals Chemicals will be used for weed control and in order to treat pest and diseases where identified. Any use of chemicals will be carried out strictly in accordance with Manufacturerʼs instructions. 7.3 Existing and Proposed Woodland and Tree Belts Management Aim and Objective: To enhance, reinforce and extend woodland and tree belt habitats, including their scrub edges. These enclose the site and contribute towards the larger green infrastructure network retained throughout the proposed development. • All Trees will be subject to a Five Year Tree Condition Survey to be undertaken by the Arboricultural Consultant. The Arboricultural Consultant shall be a member of the Arboricultural Association or Institute of Chartered Foresters. • Woodland edge area shrub species should be coppiced on a 5-7 year rotation to encourage new growth. • Coppice materials will be stored as woodpiles to provide additional deadwood habitat. • Native ground flora will be encouraged and maintained through annual removal of vigorous weed species. • All trees should be protected during construction of the proposed development, following the standards within BS 5837:2012 Trees in Relation to Construction. • Standard trees should be retained and new trees selected to replace those dead, dying or over mature, which may need to be removed for health and safety. Otherwise standing dead wood should be retained wherever possible, providing important habitats for invertebrates, bats, birds and other wildlife. • Cut back undergrowth, overgrowing or overhanging shrubs from any pathways • Hand weeding where appropriate, rather than herbicides. 7.4 New Tree Planting Management Aim and Objective: To reinforce the landscape character softening the development in the local landscape. Enhancing the biodiversity value and the green 11
Item Landscape and Biodiversity Management Strategy infrastructure of the site. • Regular checks (allowance for 3 visits per annum) to check guying support systems and tree stakes and ties and adjustment as necessary. • Additional checks to ensure trees remain upright, firm and well secured after major weather events. • Formative pruning and removal of damaged/dead branches as required. • Street trees (spine road and residential areas) to be managed in order to maintain minimum 2 metre clear stems. • Tree pits in hard surfacing to be kept weed free by hand and/or chemical weed control. Allowance should be made for 3 visits per annum. • Hand watering to maintain healthy growth as required. Allowance should be made for up to 4 visits per annum. • Any tree that fails is to be replaced with one of the same size and species as originally planted. • All Trees will be subject to a Five Year Tree Condition Survey to be undertaken by the Arboricultural Consultant. The Arboricultural Consultant shall be a member of the Arboricultural Association or Institute of Chartered Foresters. • Emergency remedial works following storm or other damage in order to make trees safe • Removal of sucker/epicormic growth where necessary. • Tree pits in hard surfaces and tree surrounds to be kept weed free by hand or chemical weed control. Gravel in tree pits to be topped up annually. • Stakes and ties to trees to be checked and adjusted up to 3 times per annum and removed when these start to impede tree growth. • Watering to maintain healthy growth as required. It is anticipated that beyond Year 5 watering will only be required to trees in hard surfaces in extreme drought conditions. 7.5 Existing and Proposed Hedges Management Aim and Objective: To enhance and reinforce linear habitats, whilst creating an attractive setting for the proposed development and ensure vegetation is established and of good form. • Hedge lines to be maintained in a weed free condition by hand or chemical means. Particular attention to be paid to the removal of climbers such as bindweed. Where feasible hand weeding should be done. • Failed plants to be replaced with ones of identical size and species. • Hedges to be trimmed once per annum in late winter (prior to start of bird nesting season in late February) to height of approximately 2 metres. • Mulch to be topped up annually. • Watering to maintain healthy growth as required (allowance for up to 4 visits per annum). Once beds are established watering should only be required in conditions of extreme drought. 7.6 Ornamental Shrubs Management Aim and Objective: Create an attractive shrub planting within areas of open space, providing a setting for the proposed development. Ensure the vegetation is established and of good form. • Shrub beds to be maintained in a weed free condition by hand or chemical 12
