Rare, Protected and Invasive Species

Threats to biodiversity

Invasive species are species that have been introduced (deliberately or accidentally) by humans, and have a negative impact on the economy, wildlife or habitats of Ireland. Today invasive species are considered to be one of the greatest threats to biodiversity, on a global scale. Species spread naturally, but human activities have intensified that spread by increasing the opportunities and frequencies available to species to expand their range. Preventing introductions is the best method of dealing with the threat of invasive species-It is illegal to deliberately introduce any non-native plant or animal species into the wild.
