Where development or construction activity is taking place in intertidal and coastal areas, specialist avian surveys for monitoring and impact assessments need to be undertaken.

APEM are experts in this area, offering a complete range of services from carrying out surveys to performing desk-based studies, data handling, modelling, reporting, stakeholder liaison and impact assessments.

Intertidal areas around the UK and Ireland are of international importance for waterbirds, including species such as brent goose, dunlin, oystercatchers and curlew.

Before development works start, it is essential to fully understand the environment and habitat. A desk-based study will provide evidence about whether the site may cross or interact with, coastal, intertidal and nearshore sites with ornithological interests (including designated sites), and if data are in existence already to support an assessment. APEM’s team are well versed in such studies and understand how best to gather data for the requirements of our client’s project needs.

Our consultancy expertise

APEM’s expert ornithologists design intertidal surveys that are robust, enabling baseline characterisation for sites and informing an impact assessment of a development of any size and scale.

Drawing on their collective extensive experience of intertidal bird surveys, the team ensure that each survey meets the needs of our clients and the regulators including:

  • Non-breeding wader and waterbird surveys (winter and migratory) in both intertidal and wetland habitats using the established methods of Wetland Bird Survey (WeBS) (I-WeBS in Ireland)
  • Core and low-tide counts (Lewis and Tierney Low Tide Waterbird Surveys (2014))
  • Through the tide cycle counts (TTTCC)
  • Monitoring, behaviour and disturbance surveys
  • Nocturnal bird surveys (using night vision)
  • Migratory patterns and seasonality

Our surveys provide data on many species, including but not exclusively:

  • Brent geese (Branta bernicla)
  • Shelduck (Tadorna tadorna)
  • Wigeon (Anus Penelope)
  • Little egret (Egretta garzetta)
  • Ringed plover (Charadrius hiaticula)
  • Grey plover (Pluvialis squatarola)
  • Lapwing (Vanellus vanellus)
  • Knot (Calidris canutus)
  • Dunlin (Calidris alpina)
  • Redshank (Tringa totanus)
  • Bar-tailed godwit (Limosa lapponica)
  • Curlew (Numenius arquata)
  • Oystercatcher (Haematopus ostralegus)

Solution-driven intertidal bird surveys

The APEM team of bird surveyors are located throughout the UK and Ireland, collecting data in digital format whenever possible using in-field digitisation techniques, suitable for digital EIA and providing our clients with both time and cost efficiencies.

Our solution-driven intertidal bird surveys can take many forms, from basic WeBS style counts to detailed daytime and nocturnal TTTCC surveys in the field. The ornithology consultancy team supports our clients at all stages of development from desk studies, to data collection and through with evidence-led ornithology impact assessments, reducing risk and increasing consent success wherever possible.

Services range from desk-based studies, field surveys, data handling and modelling to reporting, stakeholder liaison and impact assessments.

Data can be presented using GIS (both QGIS and ArcGIS) or plain tabular formats following our robust review and quality assurance processes to allow presentation of data to meet our client’s needs.

We are also experts at both client and stakeholder engagement to help provide support and agreement on our data collection methods that inform our studies, tailoring them to our client’s needs whilst also accounting for stakeholder guidance and opinions.
