REGIONAL AND LOCAL (ROAD VERGE) EFFECTS ON SIZE AND FECUNDITY IN BANKSIA-MENZIESII

Banksia menziesii is a tree at the mesic end (Swan Coastal Plain) of i ts range and a shrub at the xeric end (Eneabba Plain). Plants at the x eric end produced, on average, as many cones, set 2.3 times as many se eds and stored 8.8 times as many viable seeds in the crown, as those a t the mesic end. Plants on road verges had, on average, 2.5 times larg er crowns than those at least 50 m further from the road. Road edge pl ants produced, on average, 2.5 times as many cones, set 3.1 times as m any seeds and stored 3.7 times as many viable seeds as non-edge plants . Greater fecundity at the xeric end, including the road verges, could help offset the greater incidence of adult deaths and the reduced lik elihood of seedling recruitment after fire at Eneabba.
