Covering the North and South of Ireland.


Our terrestrial mammal experts carry out projects which involve survey and mitigation for, otters, badgers, pine martin and red squirrel.

Survey techniques include searching for signs, suitable habitat, and potential breeding sites or resting places, followed by activity surveys to detect presence or likely absence.

We use specialist equipment including live camera traps, night vision, fur traps, sand pit traps to record mammals during active periods.

Our survey methods and mitigation for terrestrial mammals follow the latest editions of good practice guidelines available, including those produced by NIEA (|Northern Ireland Environment Agency), EPA (Environmental Protection Agency) Ireland NPWS (National Parks and Wildlife Service) and The Mammal Society.

Our surveyors meet the competencies set out by the Chartered Institute of Ecology and Environmental Management (CIEEM) and have been trained in terrestrial mammal survey techniques by CIEEM, Mammal Society and the Ulster Wildlife Trust.



In Ireland, the 1992 EC Habitats Directive as instructed by the EC (Natural Habitats) Regulations requires that both seal species and all cetaceans occurring in Ireland are maintained at favourable conservation status. 

Under Article 12 of the Directive, all cetaceans should receive strict protection within the Exclusive Economic Zone. Under Article 4 of the Directive, Special Areas of Conservation (SACs) must be proposed for  a number of marine mammal species. 

Under the Wildlife (Amendment) Act 1976-2005, all cetaceans and seals are protected species listed on the 5th Schedule.

There are two groups of mammals that inhabit almost exclusively the marine environment, cetaceans and seals, Ireland has two species of seals, the Common Seal (or Harbour Seal) and the Grey Seal. 

The majority of time is spent in water were they are susceptible to noise disturbance from marine activities.

Nelson Ecology staff are experience and qualified Marine Mammal Observers. All Marine Mammal Observers are trained in JNCC marine mammal survey methods. 

We have completed marine mammal observations on projects with emphasis on marine mammals and appropriate mitigation measures to allow projects to be completed without incident or delay.
