The strength of 'edge effects' on Marbled Murrelet nesting success affects the relative murrelet productivity value of sites of different size and spatial configuration. Knowledge of their magnitude therefore informs policy on recognition of the value of existing and proposed Wildlife Habitat Areas and other areas where suitable habitat id maintained. We conducted experiments to determine the potential relative vulnerability to predation and microclimate differences between simulated nest sites located along different kinds of edge versus interior habitat on the Sunshine Coast. We did not detect differences among edge types, but statistical power was low due to small sample sizes.
