What does cat’s claw creeper look like?
- Cat’s claw creeper is a vigorous, perennial woody vine with large yellow trumpet flowers on numerous stems. Fruit develops as a long narrow capsule which contains numerous two-winged seeds with membranous wings that aid natural dispersal by wind and water.
- Each leaf has a pair of lance-shaped leaflets 2-7 cm long x 1-3 cm wide. The plant’s name (‘cat’s claw’) refers to a modification to the third leaflet, forming a three-pronged tendril with stiff tips that form hooks to aid in climbing.
Impacts of cat’s claw creeper
- A pest of forestry, urban areas and infrastructure corridors, cat’s claw creeper has the capacity to completely alter intact native ecosystems. The vine smothers and collapses native vegetation, killing mature trees and opening up the canopy for light-loving weeds. In areas where there are no standing structures, it forms dense above-ground mats that prevent growth and germination of desirable understory vegetation.
- Established plants can reproduce vegetatively from tubers and creeping stems that help make up an extensive root system. Detached tubers and cuttings may re-sprout in moist conditions to develop into climbing runners that colonise the surrounding vegetation.
- Humans particularly aid spread by propagation in gardens and rubbish dumping, where large populations of reproductive subterranean tubers persist during adverse conditions.
Where does cat’s claw creeper occur?
- Cat’s claw creeper is native to Central and South America and the West Indies where it has a distribution that covers several climatic zones, including wet tropics, temperate and tropical savannah. A popular horticultural plant now widely naturalised around the world, cat’s claw creeper was introduced to Australia as an ornamental species and was first reported as being naturalised in the 1950s.
- Cat’s claw creeper has an east coast distribution that extends from Cooktown to south of Sydney, where it is widespread in urban and peri-urban areas. Although normally considered a tropical and sub-tropical species where it poses a significant risk to biodiversity in riparian and rainforest communities, in temperate regions where it has now established it is also expanding into adjacent dry sclerophyll forests.
- Cat’s claw creeper grows in a range of soil types, but does not tolerate poorly drained soils. Plants are capable of surviving heavy frost, but germination is reduced at low temperatures and its general distribution seems to be limited by cold and dry stress.
- Plant communities in Australia most commonly invaded by cat’s claw creeper are those in riparian zones and subtropical and tropical rainforests. These include littoral rainforest and river-flat eucalypt forest on coastal floodplains listed as endangered ecological communities in New South Wales.
