Seeds are widely dispersed through the fruits hook-like bristles that embed themselves in clothing and the fur of mammals and feathers of birds. They are also spread by wind, water and soil. Have you wondered what would happen if all the seeds grew close to each other? They will not get enough water, sunlight and space needed for their growth. In some cases the seeds may remain hanging by their red or orange-coloured funicles from the open legume, the coloured funicle and aril acting as a bird attractant. The birds disperse the seed while its passage through the bird's gut may assist in germination. Emus and Mallee Fowl are also known Acacia seed dispersers.

How Is Blackjack Seed Dispersal Method

The dispersal of African Acacia seeds in the presence and absence of large mammalian herbivores and ostriches was assessed in a savanna ecosystem in South Africa In the absence of large herbivores, A. tortilis and A. nilotica pods were mainly dispersed in the shade, directly beneath the tree crown and seeds remained in pods for over 18 months In the presence of large herbivores, A. tortilis, A nilotica and A. karroo seeds were freed from pods and were dispersed into open, non-shaded habitats. Impala dispersed most A. tortilis seeds (18,900 ha^-1), giraffe most A nilotica seeds (1060 ha^-1) and giraffe and kudu most A. karroo seeds (452 and 448 ha^-1, respectively). Seedling survival in dung in open environments may exceed that of seedlings in soil shaded beneath the tree crown. It appears that seed dispersal by large herbivores may be advantageous to future seedling recruitment
