Abstract

High levels of browsing by mammalian herbivores can negatively affect the survival and growth of seedlings, and consequently revegetation and forest regeneration outcomes. Typical forms of protection (e.g. tree guards and fencing) are costly, particularly when used in large-scale projects, therefore, low-cost alternatives are needed. Based on associational refuge theory, we assessed the revegetation technique ‘cryptic planting’, whereby woody seedlings are planted within the foliage of unpalatable plants to deter browsing. We established a trial where 432 six-month-old tubestock of three woody species (Eucalyptus camphora, Melaleuca squarrosa and Leptospermum lanigerum) were cryptically (wit..
