Salamanders have been identified as potential indicators of sustainable forest management in boreal Oniario. Canada. However, little infMHiaiion is available on tiicir disirihuiion. abundance, and habitat associations wiihin the boreal forests on which to base a monitoring program. We surveyed salamanders near While River, Oniario. and related their dis tribution 10 climate and vegetation information and to habiiai suitability modds currently used for forest planning within the region, Primarily red-backed salamanders [Plelhodon cinereus Green) and blue-spotted salamanders (Amhystonui laterale Hallowell) were recorded, although both were observed in low numbers and captures varied spatially and temporally. Capture rates were 3-7 limes lower for P. cinureus than has been reported elsewhere. Trend monitoring will he expensive and have low power to delect significant declines over moderate time frames unless capture rales can be doubled and within-sitc variability in capture rates halved. We found few strong habitat relationships using either coverbuard or pitfall trap data. Plelhodon cim-reiis was negatively correlated with the volume of downed wood, which has been noted in other regions and may be an artefact of lite covcrboard survey technique. Further focused studies in the boreal foresl are re quired to support tile use of both habitat supply models and trend analysis lo monitor salamander populations.
