Protected Species Surveys

Ecohab can provide the following Specialist Protected Species Surveys and Mitigation:

Refer to Survey Timetable for Project Planning

Bat SurveysBat Roost

Bats and their roosts are fully protected under UK and European Law. If any buildings, structures (e.g. bridges) or mature trees are affected by a scheme it is advisable for an ecologist to undertake an initial assessment to determine if there is any bat roosting potential.  This can usually be undertaken all year round and can be combined with the Extended Phase 1 survey.

Should this initial assessment identify potential for roosting bats further surveys are required.  The survey effort required will depend on the roosting potential and habitats present on site that will be affected.  Ecohab works closely with licenced bat workers and can advise on mitigation and apply for a Natural England development licences should it be required.

Badger Surveys

Badgers and their setts are protected under the Protection of Badgers Act (1992).  Badger setts, tracks and signs will be identified during an Extended Phase 1 survey.  Further territory mapping of badgers or bait marking may be required should a main or outlier breeding sett be affected by a development and Ecohab can advise on the requirement for further survey and mitigation.  Our consultants also have extensive experience of holding Natural England badger disturbance licence, and supervision of sett closures.

Peregrine FalconBird Surveys

Wild birds and their nests are protected by the Wildlife and Countryside Act 1981 (as amended) and certain species included in Annex 1 afford them special protection against disturbance during the breeding season. Ecohab works with specialist ornithological consultants to undertake breeding bird surveys, winter and migrant surveys (including specialist Annex 1 bird species such as barn owl and kingfisher).


Dormouse Surveys

Dormice are fully protected under UK and European Law.  If woodland, scrub and hedgerows are present within a site then dormouse habitat may be affected.  Potential dormouse habitat can be assessed in the extended phase 1 survey, which will identify the need for further surveys  (Ecohab's Liz Powell holds a Class 1 dormouse survey licence).  Typically to determine the presence or absence of dormice nest tubes or boxes are placed in woodland and scrub and monitored from April to October.

NewtGreat Crested Newt Surveys (GCN)

Great Crested Newts (GCN) are fully protected under UK and EU law.  If any ponds are within 500m of a project area then there may be populations of newts within the site. It may therefore be necessary to do GCN surveys to determine the impact of the scheme (Ecohab's Liz Powell holds a Class 1 Great Crested Newt Survey Licence). New eDNA samples can be taken from mid-April to end of June.  Four presence/absence surveys should be undertaken between March and June and a further two surveys to determine population size (with a minimum of 2 surveys between mid-April and mid-May or 3 if GCN are present)'.


Grass SnakeCommon reptile species include slow-worm, grass snake, common lizard and adder, which are protected by UK law from killing and injury.  Reptile habitat can include scrub, grassland and ruderal vegetation.  Ecohab are experienced surveyors and handlers of reptiles and have undertaken reptile surveys and translocations where important populations of common reptiles are present.

Water Vole

Water Voles

Water voles and their places of rest are protected by UK law. If a watercourse will be impacted by a scheme it is advisable to assess the suitability of the watercourse for water voles.  Ecohab are experienced surveyors of water vole habitat and recognising their tracks and signs and provide mitigation advice when working near water vole habitat. 



Invertebrate Surveys

If ancient woodland, heathland, brownfield habitat or species rich grassland is present on site there may be a requirement to undertake invertebrate surveys.  Ecohab is experienced in conducting invertebrate surveys using pitfall, malaise, moth trap and pan trap techniques.  We work closely with entomological experts for identification to species level of most invertebrate orders including spiders.  Recent invertebrate monitoring projects have recorded species new to Britain on a London greenroof.

Harvest MouseUK BAP Mammals/ Species of Principle Importance (hedgehogs, brown hare and harvest mouse

Several UK mammal species have been added to the UK BAP list (2007) as it was recognised that these species were not being adequately taken into account during the ecological impact assessment process. 

Hedgehogs, Harvest mice and brown hare are all included on the species of principle importance list.  Ecohab has experience of undertaking surveys for these three mammal species and providing mitigation advice to clients.
