Assessment of seedling recruitment under manuka (Leptospermum scoparium) and kanuka (Kunzea ericoides) plantings at Shakespear and Wenderholm regional parks
Exclosure plots were monitored to investigate the impact of browsing on seedling recruitment by Trichosurus vulpecula, Oryctolagus cuniculus and Rattus rattus on seedlings under Leptospermum scoparium and Kunzea ericoides plantings in two Auckland Regional Council Parks (ARC), Shakespear and Wenderh...
