The best example of actively growing blanket on the east side of Ireland is to be found in the Park. This area is known as the Liffey Head Bog and is the source of the River Liffey.
Bog pools are found in the middle of the bog and are a haven for wildlife. Some creatures such as dragonflies spend most of their life feeding at the bottom of a bog pool. These pools are important feeding areas for frogs and spiders in an area which is otherwise not very nutritious.
Active blanket bog is composed of wet areas and drier raised areas known as hummocks and flat areas known as lawns. In order to survive this harsh world, there is intense competition between plants. As a result different plants survive in different areas, some in the wet areas and others in the dry areas.
