Ireland's wildlife audit unveiled
Ireland's scenic mountains, woodlands and waterways are home to more than 31,000 different species of flora and fauna.
A team of scientists found about 60% of Ireland's biodiversity are invertebrates, with just one in 10 being popular species such as plants, birds and mammals.
It is also estimated at least 7,000 kinds of algae and fungi have yet to be discovered across Ireland.
The audit is the first inventory of the country's vast biodiversity including habitats, vegetation, insects, fishes, reptiles, birds and land and marine mammals.
Dr Liam Lysaght, of the National Biodiversity Data Centre, maintained protecting Ireland's natural heritage was a building block to economic recovery - with goods and services provided by biodiversity contributing more than 2.6 billion euro (£2.3 billion) a year to the economy.
"Up until now the full extent of Ireland's biodiversity was unknown," he said.
"This report will, for the first time, allow us to accurately describe Ireland's biological resources and identify the knowledge gaps that exist.
"As the Irish economy seeks ways to revitalise itself, gaining a greater understanding of Ireland's biodiversity and protecting Ireland's natural capital needs to be one of the building blocks of our recovery."
A team of leading scientists from state bodies, NGOs and academic institutions were brought together last August to conduct the first ever audit of Ireland's natural wildlife.
The State of Knowledge report identified knowledge gaps in resources, including how to determine the risk of extinction.
