Ecological Assessments

An Ecological Assessment differs from an Ecological Appraisal in several respects. An Ecological Assessment includes the undertaking of Phase ll surveys, whilst an Ecological Appraisal does not. This means that Ecological Assessments provide an assessment of actual value, as opposed to an evaluation based primarily on professional judgement.

An Ecological Assessment is typically required where valuable ecological receptors have actually been identified, or have potential to occur (such as the presence of protected species or notable habitat), on a site at the Phase l survey stage and could be impacted by development proposals. The development proposals would be below the thresholds to trigger the requirement for the production of an Environmental Statement (ES). An ES is the written component of an Environmental Impact Assessment (EIA).

After the Phase ll surveys have been completed, the relevant ecological receptors are fully evaluated in accordance with Ecological Impact Assessment (EcIA) criteria (IEEM, 2007), any residual impacts identified and described, together with the likely effect once mitigation has been taken into account.

An Ecological Assessment typically includes the following elements:

  • Agreeing the scope of study with Natural England (NE), other statutory regulators, or the Local Planning Authority (LPA) if required;
  • Comprehensive data search using free online resources, local biological records centre and other specialist recorders as required;
  • Four-spotted Chaser (Libellula quadrimaculata)

  • Site visit and survey to 'Extended' Phase l standard (JNCC 2010);
  • Phase ll surveys;
  • Comprehensive report with full site description and colour habitat plan;
  • Summary of relevant legislation and planning policy together with other pertinent information such as Biodiversity Action Plans (BAPs);
  • Full evaluation of the ecological receptors present based on results of Phase ll surveys;
  • Full impact assessment in accordance with Ecological Impact Assessment (EcIA) criteria (IEEM, 2007);
  • Consultation with Natural England (NE), other statutory regulators and the Local Planning Authority (LPA) if required; and
  • Details of agreed mitigation, compensation or ecological enhancement

An Ecological Assessment does not typically include:

  • Recommendations for further survey work; or
  • Detailed engineering level information on mitigation design

Start of the Great Crested Newt Survey Season

Surveys for great crested newts (GCNs) can be undertaken from mid-March to mid-June depending on weather conditions. Local Planning Authorities (LPAs) require survey information before planning applications are determined in accordance with Paragraphs 98 and 99 of 'ODPM Circular 06/2005 Biodiversity and Geological Conservation'. We recommend that clients consider the requirement for newt surveys now and plan ahead. Do not miss the narrow GCN survey window. Contact us now to book in surveys and for further advice.

Supreme Court Ruling on the 'Deliberate Disturbance' Offence

In the case of Morge vs Hampshire County Council [2011] UKSC 2 on appeal from: [2010] EWCA Civ 608 the Supreme Court has overruled the Court of Appeal and given a more cautious interpretation of the Article 12(1)(b) 'deliberate disturbance' offence. The Supreme Court believed that the Court of Appeal had set the threshold for 'deliberate disturbance' too high. Whilst no minimum threshold was given by the Supreme Court, a leading environmental lawyer has reviewed the case and believes that in some circumstances disturbance of one or two individuals of a European Protected Species (EPS) may fall within the offence.
