Kangaroo grass is an erect perennial tufted grass around 1m tall. It forms swards that displace desirable pasture and native plants.
Description
- Juvenile plants have green-blue leaves which turn red-brown as they mature and become coarse.
- Seed heads are reddish, tufted, and have clusters of 8-12 large seeds with stiff wiry tails (awns).
- Seed heads occur in late spring to mid-summer.
- Seed dispersal is by gravity and attaching to animal hair or wool (stock and feral).
- Human-induced dispersal is caused by the movement of stock, hay, seed, machinery and clothing.
- Habitats include dryland pastures, grasslands, roadsides, shrublands, and wastelands.
What you need to know
Forms dense swards that can displace desirable pastures and low-growing native plants. Becomes unpalatable to stock once mature.
Management approach
This is a declared pest managed under the Canterbury Regional Management Plan 2018 – 2038 (PDF file, 10.6MB) within the exclusion programme.
Exclusion
Pests in the exclusion programme are not known to be established in Waitaha/Canterbury. If these pests were to become widely established, their impacts could be severe.
Therefore, early intervention by preventing their establishment is a cost-effective management approach.
The community should make us aware of any kangaroo grass in Waitaha/Canterbury.
Rules
Any species declared a pest cannot be sold or be in a place where plants are being sold. Pest plants cannot be propagated, bred, multiplied, communicated, released, caused to be released, or otherwise spread.
