This report details how 36 species of wetland bird are faring in Ireland based on the data gathered by more than 1,100 surveyors that have contributed details of more than 81,000 site visits since the I-WeBS survey started in 1994. National Trends are provided as well as Site-Specific Trends for 97 sites.
Details of the analysis are described in the I-WeBS Trends Report Methodology document. The Underhill technique was used to impute missing counts where appropriate, seasonal counts were indexed to focus on relative changes in abundance, and Generalised Additive Models were employed to smooth these trends. Short, Medium and Long-Term Trends have been calculated and plotted for each species.
In mid-2021 BirdWatch Ireland, supported by the Heritage Council and the Department of Agriculture, Fisheries and Marine, commissioned Digital Nature to develop hotspot maps of farmland birds in Ireland. After extensive data gathering and data preparation phases, hotspot maps at both 10km and 1km resolution were successfully produced, based on scientifically validated records of threatened species of farmland bird in Ireland.
An introduction to the project has been published online by BirdWatch Ireland. It outlines how the various records in the datasets acquired were scored. Factors taken into account included:
the species observed and its conservation status
the season of the record (e.g. breeding season or winter season)
the typical range of that species for that season
any level of breeding evidence recorded
the age of the record (more recent records scoring higher)
As reported by BirdWatch Ireland in issue 103 of their WINGS magazine, the project has gathered an unprecedented 29 datasets containing over 2.5 million records of bird observations in Ireland. Extensive BirdWatch Ireland datasets have been supplemented with valuable data provided by the National Parks and Wildlife Service, the Department of Agriculture, Fisheries and Marine, the Heritage Council, the National Biodiversity Data Centre and Bord na Móna.
After filtering for twenty-seven species of interest more than 130,000 records remained. These were transformed into a consistent structure and format, and a scoring algorithm was carefully engineered and automated to construct the required maps.
Hotspot maps were generated taking all twenty-seven species of Farmland Bird into account. Hotspot maps were also generated for various subsets of these species, including Breeding Waders. All of these maps are being updated as more scientifically validated datasets become available, and as further refinements to the scoring algorithm and scoring parameters are developed.
It has been Digital Nature’s pleasure to work with the BirdWatch Ireland Policy and Advocacy Team on this suite of innovative maps. It is hoped that they will provide valuable insights informing the intensive efforts that are underway to try and secure the presence of these species in the Irish landscape for future generations.
The Countryside Bird Survey and Irish Wetland Bird Survey are national surveys that have been gathering important scientific data on bird populations in Ireland since the 1990s. Every year hundreds of professional and citizen scientists follow carefully designed survey protocols to gather data at hundreds of selected sites around the country. This valuable data allows trends in Irish bird populations to be established, and helps inform policy at national as well as European level.
Digital Nature is focusing on the IT aspects of these surveys, supporting the National Coordinators, Ecologists and Scientific Officers on the team with data capture, validation, loading, storage and analysis solutions. Some of these elements are introduced in the latest CBS newsletter published by BirdWatch Ireland.
Digital Nature is delighted to be playing a role in this important work.
Where might be suitable places to install amenities in County Mayo that could showcase biodiversity during the day, and the Mayo Dark Sky at night?
This was a question Digital Nature tackled during 2020. We are now delighted to be in a position to share the results publicly.
A Multi-Criteria Evaluation was performed to identify locations that met the following conditions:
near to a wildlife-rich or important habitat, such as open water, wetlands or estuaries
under Dark Sky, away from fixed and mobile sources of light pollution
near to an existing road, track or path for public accessibility and construction purposes
not located on sloped land – to facilitate ease of public access
not located near to busy roads (to minimize disturbance and light, noise and exhaust pollution)
not located where the view of the sky is obstructed by local terrain – e.g. by a nearby mountain
These criteria were converted into 6 geospatial constraints and 2 geospatial factors, with appropriate weightings assigned in consultation with Ecological experts, to identify the highest-scoring sites across the county. The presence of Designated Sites was carefully considered to highlight further those locations that are not formally designated.
Data from academic, state, European, NASA and voluntary sources were successfully transformed and analysed as part of this process.
We hope that the resulting map may be of some assistance to those interested in pursuing such amenities in County Mayo.

Digital Nature has published a high-level analysis of Census 2016 commuter data for North Kildare. It includes interactive maps that illustrate the adoption of sustainable modes of transport by commuters.
This type of analysis might be of interest to residents, community groups, boards of management of schools, public transport providers, and local authority planners and engineers.
Locations with relatively low uptake of sustainable modes of commute can be identified. Exploring Maynooth, for example, the data reveal a small area very near to schools and universities yet where the amount of people sustainably commuting is very low. At the time of the census, it turns out that residents in that part of the housing estate had to travel a very circuitous route to and from their homes until construction of the estate was completed.
These maps can be used to select areas for deeper analysis, and prioritise possible interventions to increase the amount of commuting via sustainable modes of transport.
Sets of maps are provided for both the commute to school or college, and the commute to work.
