Keen observations from 7,500 nature enthusiasts over more than 50 years have allowed statisticians to observe the blooming of flowers, plants, and trees and whether climate change is a factor in their cycles.

The Central Statistics Office (CSO) analysed data from Met Éireann and the National Botanic Gardens from 1966 from six gardens across Ireland that would be rich in flora and fauna.
