BIO-DIVERSITY is short for “Biological Diversity”. It refers to the variety of life on earth and includes all plant life and animals, and the habitats of which they are part. It varies from the smallest micro-organism on earth to the largest animal. Biodiversity is important because without it the world would not exist.




The wealth of wild flowers in spring and summer at Portrunny and Lough Ree attracts a variety of butterfly species. The orange tip butterfly is one of the first to appear in April each year. It lays eggs on its food plant the lady’s smock. Later in summer other species emerge including speckled wood, meadow brown and green-veined white. In Ireland the brimstone butterfly is mainly found in limestone areas, where the native buckthorn tree occurs.The brimstone emerges in springtime from winter hibernation and lays eggs on the leaves of the buckthorn tree. A new generation of the brimstone butterfly emerges in the late summer and hibernate during the winter, and lay eggs the following spring.

Many species of trees and shrubs grow in the wild hedgerows around the Portrunny area. Ash, blackthorn and hazel are the most common tree species in the area. In early spring the golden-yellow flowers of the furze bush brighten up the whole countryside.

The grasshopper can be regularly seen in fields, along grassy roadsides and sometimes in boggy places.
