Ireland has many different types of land, each supporting unique plants and animals.
Protecting these natural spaces is important as they face growing pressures from human activities and climate change.
Habitat surveys in Ireland are an essential tool to help us understand, protect, and manage these areas.

Ireland’s Main Habitats
According to Fossitt’s A Guide to Habitats in Ireland, Ireland consists of the following habitats:
Non-marine
- Freshwater: Lakes, rivers, and streams with non-salty water (e.g. Lough Neagh).
- Grassland & Marsh: Areas with large grass cover and wet areas with plants (e.g. Shannon Callows).
- Heath & Dense Bracken: Acidic soils with low plants and dense fern-like growth (e.g. Ballycroy Park).
- Peatlands: Wet, boggy areas where peat builds up over time (e.g. Bog of Allen).
- Woodland & Scrub: Areas with large trees and shrub cover (e.g. Killarney National Park).
- Exposed Rock & Disturbed Ground: Rocky areas or land with little vegetation (e.g. Burren).
- Cultivated & Built Land: Includes farmland, towns, and cities (e.g. Dublin).
- Coastland: Where land meets the sea, like cliffs (e.g. Cliffs of Moher).
Marine
- Litoral: The area of shore exposed at low tide, like beaches (e.g. Ballybunion Beach).
- Sublitoral: The underwater zone below the low tide mark, like harbours or bays (e.g. Cork Harbour).
- Marine Water Body: Large saltwater areas, like seas or oceans (e.g. Celtic Sea).
What Are Habitat Surveys?
Habitat surveys are studies that look at the natural features of an area. They help us understand what types of habitats are in a certain location. These surveys also gather information about the plants and animals living there.
In Ireland, habitat surveys use systems (like Fossitt’s A Guide to Habitats in Ireland or the EU Annex I list of habitats). These systems help scientists describe habitats clearly and consistently. A habitat survey might include:
- Field Observations – Visiting the site and recording what plants and animals are found.
- GIS Mapping – Using maps, satellites, and GPS to create detailed maps of the area.
- Comparing Past Data – Looking at old survey results to see how the area has changed over time.
Why Are Habitat Surveys Important?
Habitat surveys in Ireland are used for many different reasons, including:
✅ Protecting Wildlife: Ireland is home to many species, some of which are rare or endangered. Habitat surveys help identify areas important for these species so they can be protected. For example, certain wetlands might provide a safe place for birds to breed.
✅ Supporting Sustainable Development: When building new homes, roads, or other projects, it’s important to consider the environment. Habitat maps show where sensitive habitats are located so developers can avoid harming them or take steps to protect them.
✅ Responding to Climate Change: As the climate changes, some habitats in Ireland may change too. Habitat surveys help us track these changes and determine what actions we must take to protect the environment.
✅ Following Legal Requirements: In Ireland, there are laws that require developers and land managers to consider the environment before making big changes to the land. Habitat surveys help meet these legal requirements by providing information about the local ecosystem.
How Are Habitat Surveys Done?
Habitat surveys in Ireland are performed in steps, depending on how detailed the study needs to be.
Step 1: Initial Survey
At first, ecologists might do a basic survey of the area to get an idea of what habitats are present. This could involve looking at old maps or images of the area and visiting the site briefly to see what habitat types exist.
Step 2: Detailed Field Survey
Next, ecologists may go into the field for a closer look. They examine the plants, animals, and environmental conditions in the area. They may also check for signs of protected species.
Step 3: Mapping and Data Analysis
Once the data is collected, tools like GIS (Geographic Information Systems) are used to create detailed maps. These maps show exactly where different habitats are located.
Step 4: Report and Recommendations
Finally, ecologists create a report that explains what they found. The report might include:
- A description of the habitats and their importance.
- Any risks to the habitats, like invasive species.
- Suggestions for how to protect or manage the area in the future.
Examples of Habitat Surveys in Ireland
EirGrid Evidence-Based Environmental Study (2016)
Purpose: To assess the impact of transmission infrastructure on habitats, particularly peatlands and grasslands.
Method: Botanical surveys were conducted at transmission sites and control areas 50 meters away.
Key Findings:
✦ Plant composition changed near the transmission infrastructure, especially in peatlands.
✦ Species like sedges, purple moorgrass, and rushes were more abundant near the structures.
Significance: The study informed updates to EirGrid’s Ecology Guidelines for transmission projects.
County Kildare Hedgerow Appraisal Survey (2022)
Purpose: To assess the condition and biodiversity of hedgerows across County Kildare.
Method: Hedgerows were mapped, and their condition and species diversity were evaluated.
Key Findings:
✦ Over 1,200 km of hedgerows were surveyed, many in poor condition.
✦ Invasive species and fragmentation were common, affecting biodiversity.
Significance: The survey informed hedgerow restoration and management strategies for local conservation.
Conclusion to Habitat Surveys in Ireland
Habitat surveys and mapping are key tools for protecting Ireland’s natural environment. They help us understand where important habitats are and what species live there. Using habitat surveys and maps, we can make informed decisions protecting our land and biodiversity for future generations.
