dc.description.abstract A geographically disjunct subspecies of spruce grouse , the Prince of Wales spruce grouse (Falcipennis canadensis isleibi ) , occurs on only a few islands in southeast Alaska . Other than limited morphology data , the scientific literature lacked any information on habitat relationships , ecology , and natural history of this subspecies . Moreover , no field studies had been conducted on spruce grouse in a temperate rainforest ecosystem . Thus , habitat relationships could not be readily inferred from the existing literature because the temperate rainforest of southeast Alaska is disfinct from other ecosystems in the range of spruce grouse . Spruce grouse were studied on Prince of Wales and Heceta Islands in southeast Alaska from April 1996 -January 1998 . Nineteen birds were captured and fitted with radio transmitters . Grouse were radio -tracked throughout the year w ith an emphasis on collecting data during the reproductive period . Habitat data were evaluated at 3 spatial scales (home range , core area , location ) using logistic regression . .A logistic model was fitted at the smallest scale of resolution , individual locations . Spruce grouse selected bog and high -volume , old -growth forest habitat and avoided clearcuts . Second -growth forest (15 -30 yrs after clearcutting ) and scrub forest habitats were used in proportion to their availability . No grouse , however , used large areas of second -growth forest exclusively , indicating that uniform structure may not be suited to all life requisites . Horizontal diversity may be an important component of spruce grouse habitat in southeast Alaska . Forest management practices which encourage horizontal diversity , avoid large patches of uniform structure , and allow connectivity of natural patches across the landscape would be less likely to isolate populations of Prince of Wales spruce grouse . en_US
