Do you know your hornwort from your lagarosiphon?
As well as managing pest plants and animals across our region, ORC’s Biosecurity team work to prevent freshwater pests from entering and spreading throughout our waterways.
One of the ways the team do this is through an educational programme called Check, Clean, Dry.

Check Clean Dry
CHECK your gear for stowaways and remove the pests either at the site or put it in the rubbish bin. CLEAN your gear thoroughly (one way is to use 10% dishwashing detergent mixed with water and leave the item wet for 10 minutes, visit this page for more ways). DRY it for 48 hours before relocating to another waterway!
