For example, for a long term effect that will definitely occur, at a regional scale with a largechange from the baseline the score is 400. The Magnitude (Severe, Moderate or Low) of the effecthas been determined using the thresholds below (:Magnitude of EffectScore ThresholdSevere 400 - 211Moderate 202 - 22Low 13 – 4Table 5-2 : Magnitude of effect score thresholds5.5.2. Description of receptorIn order to identify the level of impact on each receptor or feature the following has been described:Sensitivity – the sensitivity or tolerance of the receptor to the effectRecoverability – how rapidly the receptor recovers to baseline state following effectImportance – Receptor’s importance in terms of its occurrence in the UK, itsnational/international significance and its conservation or commercial valueReceptor Aspect Classification DefinitionSensitivity High Receptor or feature is highly sensitive to effect and will bedetrimentally damaged (in ecological terms killed/destroyed) byeffectModerateSome damage may occur to the receptor or featureLowSome minor damage to receptor or featureRecoverability Low No recoveryModerateRecovery to baseline conditions within years
