Lange & Graham (1983) conducted experiments on the influence of rabbits on Acacta regeneration in the arid areas and A. kempeana was amongst the four species tested. Results showed that seedlings were severely pruned even with lowered post-myxomatosis rabbit population densities. Rabbit grazing pressure would significantly affect the recruitment in add zone Acacia populations.
Entry of water and subsequent germination of impermeable seeds of A. kempeana occurs after the strophiole lifts and cracks. The opening of a strophiole is induced by heat and is affected by the splitting of thin walled cells lying beneath the short palisade cells within the strophiole. The entry of water is facilitated by xylem vessels which almost touch the internal side of the seed coat and water could then reach the internal endosperm and embryo, Hanna (1984).
An analysis of oils of A. kempeana was presented in Bart et al. (1988) though the species was not further discussed in the text. The percentage of oil is very low, 0.01%, amongst the lowest of all the plants tested.
Three species of mistletoe have been collected on Acacia kempeana, almost equal low numbers of Amyema maidenii, pale-leaved mistletoe and Amyema preissii, wire-leaved mistletoe plus a single collection of Lysiana murrayi, mulga mistletoe.
Descriptions and illustrations of the life cycles of the Cossid moths, whose larvae provide witchetty grubs were given by Tindale (1953). The principal Acacia hosts are A. ligulata and A. kempeana, the larvae living on or in the roots of the shrubs. The larvae are popular with Aborigines and seem to hold fascination for white Australians who, except for the flies they swallow, eat so few insects.
A. kempeana seed is reported by Isaacs (1987) to be used by the Aborigines after being ground into a flour.
