The Yellow Mountain Bell has been declared as Rare Flora under the Western Australian Wildlife Conservation Act 1950 in 1980 and currently meets World Conservation Union (IUCN 2001) Red List Category Endangered. It is endemic to mountain summit areas of the Stirling Range The only known locations where Darwinia collina is found are Bluff Knoll, Coyanarup Peak, Bakers Knob and East Bluff in the Stirling Range National Park.
It is a bushy shrub up to 1m high with minutely toothed leaves and flowers In March and April & August to November. Each bell is a cluster of drooping flowers with white petals and stigmas up to 2 cm long that are enclosed by broad, lemon-yellow petal-like leaf bracts.
The Yellow Mountain Bell are killed by fire and regenerate from soil-stored seed flowering two to five years after germination. Reproductive maturity is not reached until seven to ten years and numbers are thought to decline after a period of around twenty years as the surrounding vegetation becomes too dense for them to survive. They are pollinated by nectar-feeding birds and as birds locate food by sight, the yellow mountain bell is brightly coloured. The flowers are pendulous to keep rain from the nectar and are positioned so that birds can probe the bell both from the ground and by perching on them.
We aim to protect endangered species of plants through education and learning about how interesting and important they are.
We recognise that biodiversity conservation is essential both for our existence and intrinsically valuable in its own right. Biodiversity provides the fundamental building blocks for the many goods and services a healthy environment provides, such as clean air, fresh water and food products. We all influence whether plants are sustainably used and conserved for future generations. Plants are relevant and vital to all of us and we should all be aware that plants across the world are endangered with many facing extinction. Plant diversity is especially important because it underpins the functioning of all ecosystems. We support efforts that tackle endangered flora and fauna, with many facing extinction.
At HideAway Haven we recognise that sustainable living is ultimately necessary if we are to ensure the long-term conservation of all our natural resources, by properly valuing the many benefits of our natural resources.
