Earlier this year IFI reported on the attempted eradication of New Zealand pigmyweed (Crassula helmsii) from a stretch of the Grand Canal at Lullymore Co. Kildare. The operation involved a combination of chemical treatment and physical removal of the weed which left the stretch of canal stripped of all plant life.

The canal was re-watered in the last week of March and since then the stretch of canal has been completely recolonized by native vegetation.

This gives a good indication of the ability of the canal habitat to naturally regenerate after an intensive eradication programme for a particularly invasive species.
