The Pilliga or white bloodwood (Clemson, p. 63) yields large volumes of pollen and honey when it flowers in the autumn, especially when ground moisture is high.
The pollen has a crude protein level of 21.8% to 24%, but iso-leucine levels are low, averaging 3.6% (Table 12). This would reduce the overall digestibility of the crude protein.
Yields of 200 to 300 grams of pollen per day and 40 to100 kg of honey per hive for the flowering have been reported. After the honey flow the hives are often full of bees.
Bloodwood pollen would be useful to trap and feed
back to the bees at a later date, as bees find it very palatable.
