What Are Protected Species Surveys?

Protected species surveys assess plants and animals that are legally protected under national (like Ireland’s Wildlife Act) or EU law (such as the Habitats & Birds Directives). These laws protect species that are rare, threatened, or important for healthy ecosystems.

Before changing a site – through building, clearing land, or managing water – surveys may be required to check for protected species. Some examples of protected species in Ireland include:

• Lesser horseshoe bat (flying mammal)
• Otter (non-flying mammal)
• Hen harrier (bird)
• Cottonweed (plant)

Surveys may also support assessments for other species groups, including fish, amphibians, reptiles, and invertebrates (e.g. freshwater pearl mussels).

Why Are These Surveys Required?

In Ireland and Northern Ireland, it is illegal to:

• Pick or destroy protected plants
• Injure or kill protected animals
• Damage breeding or resting areas
• Disturb animals during sensitive times (like hibernation or nesting)

As a result, planning authorities often require a professional ecologist to carry out protected species surveys before approving land development projects. These surveys help avoid harm to wildlife and reduce legal or planning risks for your project.
