Risk categorization for forestry or arboriculture operations.

Request

I would like to understand how your council categorises risk for forestry or arboricultural operations. I am specifically looking for the risk category, description and timeframe of each risk category you have. This should be easy to obtain from your relevant operational forestry or commisioning forestry team.

Please complete the below with your council's actual categories:

Decision

'LCC Categories Risk for Arboriculture operations using the Quantified Tree Risk Assessment (QTRA) Method, each tree is scored on its risk factor, ranging from 1/10000 to 1/10000000 (1 in 10k is higher risk, 1 in 1million is extremely low risk). Trees with high-risk scores of 1/10k have higher priority works to be recommended by surveyors within 3 months, 6 months and 1 year, dependent on the surveyor's judgement upon visual inspection'
