Dry Wallum The dry wallum is a harsh environment that is battered by the sun and wind every day and with a base of porous sand; water availability is very scarce and must be conserved. The abiotic factors in the dry wallum are that the area is exposed to high amounts of sunlight which causes a loss of water in the leaves through transpiration. Since the wallum is so dry and hot; bush fires play a major cycle in the dry wallum which the trees have adapted to cope with. The roots of the plant and
