Species that were around and thriving 30 years ago are now facing extinction.
This is according to Billy Flynn of the Irish Wildlife Trust's Monaghan Branch who told Northern Sound this week that the county needs a conservation ranger.
Mr Flynn said the situation is getting worse, not better, and "nature and the environment is in a bad state".
The local ecologist added the curlew was now most at risk to extinction in Co Monaghan - a place, he added, that was synonymous with the wetlands.
Mr Flynn says the causes are many but much of what is happening is because of the way in which the land is now being managed.
