There is dead wood • Other species include Beech, Sweet Chestnut, throughout the woodland, providing excellent Pedunculate Oak, Ash, Yew, and to a lesser extent habitat conditions for dead wood invertebrates Holly, Rowan, Silver Birch, Cherry and Hawthorn 7 HAMPSTEAD HEATH WOODS SSSI urBan interpretation • standing deadwood as design features and nature based ‘play on the way’ • sorbus torminalis as a key tree species - drought tolerant, excellent for pollinators and birds • locally found species such as bluebells, broad buckler ferns and sedges incoporated into planting plans 8 SANDY HEATH SSSI KEY ELEMents SANDY HEATH • Approximately 0.22 ha of extensive European (Frangula alnus) and Broom (Cytisus scoparius) Gorse (Ulex europaeus) planting • Lowland Heathland is a priority habitat for • Gorse is one component of lowland heath that the Camden, London, and national Biodiversity gave Hampstead Heath its name. Action Plans. • Gorse is a typical plant of heathland and provides habitat for bird species such as long- tailed tits, blackcaps and whitethroats which is of considerable local importance • Other species include Alder Buckthorn 9 SANDY HEATH SSSI urBan interpretation • European Gorse (U. europaeus) flowers from January to June and Western Gorse (U.gallii) flowers from July to December • Together, they provide year round flowers for pollinators and habitat for nesting birds • Both are UK natives found on heaths, railway embankments and acidic soils • Heathland and flower rich acid grasslands are suitable habitat types for green roofs and will inspire the planting in much of the public realm, being combined with ecologically complimentary ornamental species 10 MAXIMISING GREENING IN INDUSTRIAL SPACES MAXIMISING GREENING IN INDUSTRIAL SPACES LIVING roofs • large areas of bird and invertebrate habitat • helps to slow down storm water run off • acid grassland, open mosaic and heathland • carbon sequestration • reduces urban heat island effect are all suitable habitat types for green roofs that complement the local ecology of Murphy’s Yard 12 MAXIMISING GREENING IN INDUSTRIAL SPACES VerticaL GreeninG • significant reduction of urban heat island • reduces wind speeds • provides biodiversity and natural habitat effect • sequestration of carbon • slows down storm water run off • improvement of air quality • aesthetic appeal • proven positive impact on educational • deadens sound • psychological impact on urban dwellers environments and social behaviour 13 SUSTAINABLE URBAN DRAINAGE water is released back into the atmosphere via evapotranspiration, cooling the air planting takes up water and green roof substrate holds on to moisture the surface area of all the leaves combined in the tree canopies holds on to a significant amount of water roots suck up great quantities of water and release it back into just like trees, the leaves in green facades hold on to water and their roots suck up rain water roof run off can be collected in water butts and any overflow is taken into adjacent rain gardens this water can be used later to irrigate during times of drought depressions in the landscape store rainwater, creating flooded ponds planting needs to be tolerant of both drought and flooded conditions 14 CURRENT PROPOSALS MURPHY’S YARD current MasterpLan proposaL HABITAT TYPES POTENTIAL FOR LIVING ROOFS (combination of heathland, acid grassland and open mosaic) HEATHLAND + FLOWER RICH ACID GRASSLAND OPEN MOSAIC INSPIRED PLANTING ACID GRASSLAND, IMPROVED TREE LINES + HEDGES FLOWER RICH RAIN GARDENS WITH TREE PLANTING Note layout is indicative only and subject to change.
