Frogs are hard at work trying to repopulate their home in Dublin after it was nearly wiped out last autumn.
Tonnes of soil dredged up from a pond at Sean Moore Park in Tallaght was dumped in their swamp last September.
There were fears the vital habitat would take years to recover -- but wildlife experts have counted 150 breeding pairs at the site at the weekend.
But Collie Ennis, science officer with the Herpetelogical Society of Ireland, says frogs are very resilient.
"Frogs are incredible creatures and if you give them a half a chance and a bit of space to do their romantic thing in spring they will produce vast quantities of spawn and repopulate an area very quickly," he says.
"Of course when the frogs start returning to a place that means predators like herons and otters will start using the area as well to have a munch on some of the less fortunate frogs -- but it's all part of the natural cycle," he added.
