Letter from The Friends of Ecological Reserves To Gulf Islands National Park Advisory Board December 5th 2012 Re: Gulf Islands Parks plan and management of former Ecological Reserves on Saturna and Brackman Islands. This letter is a request from Friends of Ecological Reserves (FER) to the advisory board to use the boundaries of former ERs
Abstract: Predator effects on prey demography have traditionally been ascribed solely to direct killing in studies of population ecology and wildlife management. Predators also affect the prey’s perception of predation risk, but this has not been thought to meaningfully affect prey demography. We isolated the effects of perceived predation risk in a free-living population of
Dr. Liana Zanette, Associate Professor in the Dept. of Biology , University of Western Ontario has done research on “Perceived Predation Risk Reduces the Number of Offspring Songbirds Produce per Year”. Her website for Zanette Lab carries the most recent research article and has links to excellent images of Song sparrows and their predators, and
Abstract Predator-induced changes in physiology and behaviour may negatively affect a prey’s birth rate. Evidence of such indirect predator effects on prey demography remains scarce in birds and mammals despite invertebrate and aquatic studies that suggest ignoring such effects risks profoundly underestimating the total impact of predators. We report the first experimental demonstration of indirect
The Friends of Ecological reserves maintains that the baseline work done on Ecological Reserves now ceded by the province to Parks Canada justifies them as still being recognized as special research areas and it is hoped that they will be designated as such.

Paul Linton who was the Ecological reserve warden for Brackman Island has done a great job in producing a phenology, or time of blooming of the plants on Brackman Island. This is also an excellent species list as well. This was also done for 1995 Phenology see PDF Brackman Island Phenology_1999
Paul Linton has compiled the Phenology for Brackman Island in 1995 . (Also see 1999’s version.) Brackman Island Phenology_1995
