“…Our results corroborate findings of previous studies on the effects of forest management practices on amphibians, with lower overall abundance of amphibians in clearcuts (Pough et al, 1987;Raymond and Hardy, 1991;Petranka et al, 1993Petranka et al, , 1994Ash, 1997;Harpole and Haas, 1999;Grialou et al, 2000;Ash et al, 2003;Knapp et al, 2003;Renken et al, 2004). As previously found, adult habitat use differed among species (deMaynadier and Hunter, 1998;Strojny, 2004), with wood frogs, spotted salamanders, and eastern red-backed salamanders preferring uncut or partially cut forest, and adult green frogs and American bullfrogs being more tolerant of canopy removal.…”

“…Amphibians form a large part of the vertebrate biomass in forested ecosystems in north-eastern North America and play an important role in ecosystem processes (Burton and Likens, 1975a,b;Wyman, 1998). Furthermore there is a great deal of debate as to how forest management influences amphibians because of uncertainty in how severely practices such as clearcutting affect populations, and how long such effects may last following harvesting (Petranka et al, 1993Petranka, 1994;Ash, 1997;Chazal and Niewiarowski, 1998;Harper and Guynn, 1999;Ford et al, 2002;Ash et al, 2003). There is also uncertainty as to the relative effects of different management practices on amphibians, for example the frequency and intensity of harvesting efforts (Bennett et al, 1980;Aubry, 2000;Bartman et al, 2001;Ryan et al, 2002) and the retention of biological legacies such as leaf litter and coarse woody debris (CWD) (Aubry, 2000;Moseley et al, 2004;Strojny, 2004).…”

“…Similarly, declines in reproductive success may not be evident for more than three years following forest disturbance (Ash et al 2003, Patrick et al 2006, Cummer and Painter 2007, Matthews et al 2010. Ash et al (2003) noted that P. jordani captures in 10-year old clearcuts had proportionately fewer juveniles and adult males in reproductive condition.…”

Do silvicultural practices to restore oaks affect salamanders in the short term?

et al. 2015

Salamanders are an important ecological component of eastern hardwood forests and may be aff ected by natural or silvicultural disturbances that alter habitat structure and associated microclimate. From May to August in 2008 (pretreatment) and 2011 (post-treatment), we evaluated the response of salamanders to three silvicultural practices designed to promote oak regeneration -prescribed fi re, midstory herbicide application and shelterwood harvest -and a control. We trapped salamanders using drift fences with pitfall traps in fi ve replicates of the four treatments. Only the southern gray-cheeked salamander Plethodon metcalfi and the southern Appalachian salamander P. teyahalee were captured in suffi cient numbers for robust statistical analysis. We analyzed data for these species using single-species dynamic occupancy models in statistical software program R. We allowed changes in four covariates to infl uence extinction probability from pre-to post-treatment implementation: 1) percent leaf litter cover; 2) percent understory cover; 3) percent CWD cover; and 4) percent canopy cover. h e fi nal combined model set describing extinction probability contained four models with Δ AIC Ͻ 2 for P. metcalfi and nine models with Δ AIC Ͻ 2, including the null model, for P. teyahalee . For both species, the 95% confi dence intervals for model-averaged extinction probability parameter estimates overlapped zero, suggesting none were signifi cant predictors of extinction probability. Absence of short-term salamander response in midstory herbicide and prescribed burn treatments was likely because of minor or transitory changes to forest structure. In shelterwood harvests, any potential eff ects of reduced canopy and leaf litter cover may have been mitigated by rapid post-treatment vegetation sprouting. Additionally, climatic conditions associated with high elevation sites and high amounts of rainfall in 2011 may have compensated for potential changes to microclimate. Continued monitoring of Plethodon salamanders to assess responses at longer time scales (e.g. Ͼ 3 years post-treatment) is warranted.

“…Plethodon kentucki and Ensatina eschscholtzii reach sexual maturity at three years but are known to live as long as 15 yr (Staub et al, 1995;Marvin, 1996Marvin, , 2001. Some studies have reported observations on the longevity of other plethodontids (e.g., 6-15 yr for Desmognathus quadramaculatus, Castanet et al, 1996;Bruce et al, 2002;5-11 yr for Desmognathus ochrophaeus, Houck and Francillon-Vieillot, 1988; 3-10 yr for Plethodon metcalfi, Ash et al, 2003). Whether Green Salamanders have longevities similar to other plethodontids or if any relationship between age at maturity and longevity is a consistent life-history trait within the taxon is unknown.…”
