'Weed seeds and whoopsie daisies': viability of bitou bush Chrysanthemoides monilifera seeds in fox (Vulpes vulpes) scats.

Abstract

In 1994, a small trial was conducted to test the viability of bitou bush [C. moniliferum] seeds after ingestion by foxes on Bherwerre Peninsula on the east coast of New South Wales, Australia. An average of 244 seeds (range 92-594) were found in each fox scat. Viability trials showed that 50-70% of bitou bush seeds germinated under ideal propagation conditions and favoured well drained soils. Seeds from fox scats also remained viable in the field, although germination rates were lower than in the nursery trial.
