Serrated tussock (Nassella trichotoma)
Serrated tussock (Nassella trichotoma) is a weed of regional and national significance because of its invasiveness, destruction of pastures, negative impacts on biodiversity and difficulty to control.
Serrated tussock seeds are prolific, have an extensive life and spread via wind, creating a significant and on-going risk to agriculture and natural environments.
Serrated tussock grows vigourously but has little grazing value becaue of its high fibre and low protein content. Dense infestations cause significant loss of livestock production.
In native grasslands serrated tussock competes with native species, significantly reducing biodiversity.
