Biogeochemical legacy of prescribed fire in a giant sequoia–mixed conifer forest: A 16‐year record of watershed balances

“…Crown scorch and tree death could have decreased interception of rain and snow by the canopy in the burned catchment. Interception rates reported from other conifer forests range from 20% to 40% of precipitation [ Blew et al , 1993; Fahey et al , 1988; Friedland and Miller , 1999; Stottlemyer and Troendle , 1999, 2001]. However, mean throughfall event depths were not statistically different between burned and unburned plots at our study site during the first 2 years after fire, which were dry years (J. Chorover, unpublished data).…”

Nitrogen cycling following mountain pine beetle disturbance in lodgepole pine forests of Greater Yellowstone

“…Within the current outbreak, soils were notably cooler than in undisturbed sites, most likely in response to increased litter depth. Though soil moisture was not measured in this study, soil moisture probably increased due to deeper litter and reduced transpiration caused by tree mortality (Stottlemyer and Troendle, 1999;Tan et al, 2008;Griffiths et al, 2010). Experimental additions of needle litter have been shown to increase soil moisture in lodgepole pine forests even in the absence of tree mortality (Cullings et al, 2003).…”

Amount and reactivity of dissolved organic matter export are affected by land cover change from old‐growth to second‐growth forests in headwater ecosystems

“…The amount of C contained within the O horizon determines the amount of DOM available for microbial processing and subsurface transport (Lee, Park, & Matzner, 2018; Nave, Vance, Swanston, & Curtis, 2010). Pre‐harvest soil C content was similar between the hillslopes (Table S2, Reuss et al, 1997; Stottlemyer & Troendle, 1999). However, as seen elsewhere, we found higher O horizon C stock, DOC concentrations and annual export in the old‐growth compared to the second‐growth forest that regenerated on the harvested hillslope (Chatterjee, Vance, Pendall, & Stahl, 2008; Chatterjee, Vance, & Tinker, 2009).…”
