Those of you who follow our Instagram or FB pages will know that the Balcony Garden at Up On The Rooftop is home to two Australian Native Bee hives of the species Tetragonula Carbonaria. Such sweet and gentle little creatures that are stingless, that quietly go about their days foraging nectar and pollen from the garden and surrounding native plants.
Bees, including honey bees, native bees and solitary bees pollinate plants. (Pollination is where insects move pollen from one plant to another, fertilising the plants so that they can produce fruit, vegetables, seeds and so on).
There are over 2000 species of Native Bees in Australia which are important pollinators of our magnificent fauna and they are showing great potential as specialist pollinators of crops such as macadamias and lychees! Some live in colonies (much like European bee colonies) and some are solitary such as the beautiful Blue Banded, Leafcutter and Carpenter Bees.
If all the bees became extinct, it would destroy the delicate balance of the Earth’s ecosystem and affect global food supplies. There are other diverse pollinators too such as butterflies and other small insects that actually do much of the work of pollination apart from bees. With about 40% of the world's insects in decline what can we do in our urban gardens to help keep these numbers up by providing safe havens and food sources?
Commercial honey bees are not native and were introduced to Australia in c18th principally for their honey production capabilities, and so this continues today. Honey bees can produce up to 45kg of honey a year compared to a native bee hive in Queensland (optimum conditions exist up there) which might produce 1 Litre. Native bees have co-evolved with native plants for millions of years in Australia. There is a huge range of native plants that rely on native bees for pollination. The introduced honeybee is not able to pollinate these plants.
If more people raise Australian Native Stingless bees in urban settings, there will be more hives and there will be more urban bees.
Unfortunately, not all of the Australian continent is suitable for keeping stingless bees. These bees occur naturally in Australia’s warmer and wetter parts, and hive sellers will usually insist that they be kept and cared for in these areas. Google will provide you with a number of resources and Aussie bee keepers who can help you become a custodian and set up your native bee hive. A great place to start for comprehensive information about NAtive Bee keeping is with Dr Tim Heard of Sugarbag Bees
If you would like to read more about providing your local Australian Native Bees with a home away from home, take a read of another Blog on my site The Balcony Meadow - B&B Highway Rest Stop (only a short read) and consider providing a rest stop for our urban bees.
