Rare and Endangered Species

Rare pine marten in the Irish wilderness

Despite Ireland’s rich biodiversity, certain species like the pine marten, otters, red squirrels, and the great yellow bumblebee are rare and endangered. The pine marten has been afforded protection under the Wildlife Act 1976, attributed to past reductions in its range and population. Initiatives such as the Arden Wood Pine Marten Project are enhancing the understanding of the species and have played a role in the resurgence of pine martens in Northern Ireland.

The otter population in Ireland is relatively stable and is considered one of the most stable in Europe. However, the Great Yellow Bumblebee is considered to be quite rare and has been classified as Endangered on the Irish Red List. The red squirrel population in Ireland is being affected by:

  • competition with grey squirrels

  • predation from avian predators and land animals such as domestic cats or foxes

  • the spread of squirrel pox virus by grey squirrels.

Irish zoos and aquariums contribute to conservation efforts by engaging in activities such as breeding threatened species, engaging with governments, supporting conservation efforts, and protecting native wildlife. Specifically, Dublin Zoo operates a Centre for Species Survival, supports over 25 conservation projects globally, and has successful breeding programs for species at risk.

These institutions have evolved over time, shifting focus towards conservation initiatives, breeding programs, and raising public awareness about wildlife.

Top Tips for Responsible Wildlife Watching

Following certain guidelines is essential to ensuring a responsible and enjoyable wildlife watching experience. Maintaining a respectful distance when observing wildlife, refraining from pursuing or approaching them, and avoiding feeding the animals are some measures that can be taken to respect and safeguard the natural habitats of Irish wildlife. Irresponsible wildlife watching can have serious consequences, such as habitat destruction, causing stress to animals resulting in changes in their behavior, overcrowding, animal cruelty, and disruption of migratory patterns.

The advised distance to maintain from wildlife in Ireland is to provide them with ample space and avoid causing disturbance. Observing wildlife from such a distance helps minimize stress and preserves their natural behavior. Furthermore, refraining from feeding wild animals is significant due to the potential development of harassment behavior in animals and the establishment of an unhealthy dependency on humans for food, which disrupts their natural foraging behaviors and diet.


From the rich biodiversity of Ireland’s ecosystems to the enchanting beauty of its remote islands, Ireland’s natural heritage has been a captivating journey. The country’s commitment to conserving its wildlife, reflected in its national parks, zoos, and aquariums, underscores the significance of preserving this rich biodiversity. As we admire the beauty and diversity of Irish wildlife, let’s also remember our responsibility to ensure that future generations can experience the same enchantment.
