Mapping Biodiversity
Heritage Council's Biodiversity Watch Project allows you to enter sightings of plants and animals you see in your area ie in a local park, woodland or seashore. There's also a Road Kill Survey. No registration necessary.
Nature’s Calendar has been taken out of Biology.ie and moved to its own domain
www.naturescalendarireland.com. This was set up with funding from the Botany department at TCD.
