Proposal

Common Oak - North boundary of staff car park - Basal growth and holly prevent inspection of main stem to south. Dead ivy encroaching entire structure. Tree appears to have been reduced within 2-3 years, poor response growth. Remove basal growth and Holly re-inspect south side of main stem. Re-inspect in summer months to monitor crown vitality. Common Oak - North boundary of staff car park - Percussion test of the main stem with a nylon hammer resonates a tone suggesting decay/hollow extending up to 1m from base on south side. Loose bark present and white mycelium layer and rhizomorphs present beneath bark, suspected Honey Fungus. Tree historically reduced with poor response growth. 5% major deadwood in crown. Remove major deadwood over 50mm in diameter. Due to the suspected colonisation of Honey Fungus further inspection of root collar with use of Sonic Tomography and a Resistograpth is recommended to confirm the presence of decay. Mixed Species Group - North east corner of staff car park - Group of 1no Ash and 1no Oak. No access to both trees due to dense Holly. 1no Ash has damaged boundary fence. 1no Oak has 5% major deadwood in crown. Prune/remove shrubs to allow access to main stems and re-inspect. Remove major deadwood over 50mm in diameter. Common Ash - East boundary of staff car park - Third party tree. Over-extending lateral projecting west over car park. Crown in close proximity to building. Inform third-party owner of duty of care and requirement to inspect, assess and manage the risk posed by the tree.
