“…Our results provide a geographical framework for conserving turtle populations by identifying the spatial extent of area required to protect the most vulnerable population segments: nesting females, eggs, and hatchlings. More specifically, our data indicate that aquatic turtles in aggregate use considerably more terrestrial habitat for nesting than typically included in the wetland protection zones generally delineated as 30-120 m from wetland boundaries in the United States and Canada (Houlahan and Findlay, 2004;Lee et al, 2004; see also Castelle et al,1994). For example, a 93 m zone surrounding wetlands encompasses just 50% of nests (Table 4).…”

Because particular life history traits affect species vulnerability to development pressures, cross-species summaries of life history traits are useful for generating management guidelines. Conservation of aquatic turtles, many members of which are regionally or globally imperiled, requires knowing the extent of upland habitat used for nesting. Therefore, we compiled distances that nests and gravid females had been observed from wetlands. Based on records of > 8000 nests and gravid female records compiled for 31 species in the United States and Canada, the distances that encompass 95% of nests vary dramatically among genera and populations, from just 8 m forMalaclemys to nearly 1400 m for Trachemys. Widths of core areas to encompass varying fractions of nesting populations (based on mean maxima across all genera) were estimated as: 50% coverage = 93 m, 75% = 154 m, 90% = 198 m, 95% = 232 m, 100% = 942 m. Approximately 6-98 m is required to encompass each consecutive 10% segment of a nesting population up to 90% coverage; thereafter, ca. 424 m is required to encompass the remaining 10%. Many genera require modest terrestrial areas (zones) for 95% nest coverage (Actinemys, Apalone, Chelydra, Chrysemys, Clemmys,Glyptemys, Graptemys, Macrochelys, Malaclemys, Pseudemys, Sternotherus), whereas other genera require larger zones (Deirochelys, Emydoidea, Kinosternon, Trachemys). Our results represent planning targets for conserving sufficient areas of uplands around wetlands to ensure protection of turtle nesting sites, migrating adult female turtles, and dispersing turtle hatchlings.

“…In this regard, the most significant concern is that forest management operations may expose mineral soil and facilitate transport of sediment in runoff and subsequent deposition in water (see reviews in Steedman and Morash 2001, Steedman et al 2004, Croke and Hairsine 2006. Most jurisdictions prescribe riparian buffers within which forest management operations are prohibited or restricted to minimize the risk of sediment entering water (Lee et al 2004.…”

“…In contrast, an incorrect conceptual model of hydrological processes in a given landscape increases the risk of using mitigation strategies that will not protect aquatic systems from forest management activities. Increasing recognition that one-size-fits-all prescriptions are often inappropriate (Macdonald et al, 2004) is leading to a growing trend of developing more site-or regionspecific management approaches such as variablewidth riparian buffers (Lee et al, 2004;Macdonald et al, 2004).…”

Recent research in forest hydrology in Canada is reviewed, with a focus on studies of hydrological and hydrochemical processes in natural and disturbed forest landscapes during the 2003-2007 period. The value of hydrologic classification schemes for understanding these processes and guiding effective forest management practices is highlighted, as are the spatially and temporally extensive hydrologic datasets needed to test these classifications. Studies of hydrologic response to natural and anthropogenic forest disturbance are reviewed, and the strengths and limitations of paired-basin experiments for assessing forest disturbance effects on watershed processes are evaluated. Recent shifts in the context of forest hydrology research in Canada are presented, such as issues of climate warming, the mismatch between experimental and management scales, and the increasing need to address cumulative effects of both natural and anthropogenic forest disturbance.Résumé : Les recherches récentes en hydrologie des forêts sont examinées, l'accent étant mis sur l'étude des processus hydrologiques et hydrochimiques dans les paysages forestiers naturels et perturbés de 2003 à 2007. La valeur des plans de classification hydrologique pour la compréhension de ces processus et pour l'orientation des pratiques de gestion efficace des forêts est mise en relief, tout comme les ensembles de données extensives, spatiales et temporelles, nécessaires pour tester ces classifications. Les études de la réponse hydrologique aux perturbations naturelles et anthropiques de la forêt sont examinées. Sont également évaluées les forces et les limitations des expériences entourant les bassins jumelés pour l'analyse des effets de la perturbation des forêts sur les processus liés aux bassins hydrographiques. Sont aussi abordés les changements récents touchant les recherches en hydrologie des forêts au Canada, notamment le problème du changement climatique, le décalage entre l'échelle expérimentale et l'échelle de gestion, et le besoin croissant de s'attaquer aux effets cumulatifs de la perturbation des forêts, d'origine naturelle ou anthropique. 114Canadian Water Resources Journal/Revue canadienne des ressources hydriques
