Risk of plant poisoning after a flood

Flooding or high rainfall can cause the growth or increased abundance of many toxic plants. The growth of these plants tends to occur more rapidly than pasture grasses after rain events. They can be harmful, or in some cases fatal, to livestock, so it's important that you take care to minimise risks.

If you notice a plant you are not familiar with, you should get it identified as soon as possible so action can be taken if needed. Restrict access where possible or ensure a ready supply of alternative feed to prevent livestock eating toxic plants.

This guide explains some of the most common poisonous plants you may see post-flooding, the signs that you may see in poisoned animals, and the ways you can identify and treat poisonous plants on your property.
