Rabbits are concentrated at locations previously cleared and grazed such as Haycock Point, Mowarry Point and at picnic and camping areas.
Foxes and cats occur throughout the park, although numbers are higher near the Eden tip.
Wild dogs are occasionally reported in the park. They can be divided into three groups:
- hybrids with domestic dogs
- feral dogs.
Wild dogs sometimes impact on livestock in adjacent areas, and there is a need to minimise their attacks on stock. It is NPWS policy to remove feral dogs from its lands.
Introduced plants occur in areas of the park where agriculture and forestry has occurred in the past. Agricultural weeds are mostly at Haycock Point and Mowarry Point.
Abandoned pine plantations are found in several areas of the park, primarily:
- between Barmouth Beach and the Pinnacles
- west of Leather Jacket Bay
- adjacent to the Green Cape Road near Bittangabee Creek.
Native species have sprung up in many of these former plantations but large numbers of pines remain. Pines have also spread from the plantations into adjacent native communities.
The new addition to the north of the Pambula River also has a variety of weed species, in particular bitou bush. This species, although largely contained due to the work of local landcare, has the potential to spread and threaten large areas of native vegetation.
Other identified weed species include:
- stinging nettle
- bridle veil creeper
