“…White-footed mice (Peromyscus leucopus) did not change diet or trophic position within intercropped and non-intercropped pine forests, indicating that this species maintained functional roles in a novel environment (Briones et al 2013). As part of the same study, Homyack et al (2014a) found that, over a 4-year period, natural succession in intercropped forests appeared to exert greater influence on rodent communities than intercropping.…”

In the United States, intensively managed forests (IFM) comprise approximately 9% (27.9 million ha) of total forest area. These forests are primarily in highly productive areas and are managed primarily for wood and fiber production. Intensively managed forests provide both opportunities and constraints for conservation of vertebrate biodiversity. However, because a comprehensive review of these opportunities and limitations within the U.S. is lacking, we reviewed effects of typical silvicultural management regimes within IFM on terrestrial vertebrate species. The typical silvicultural regime in IFM includes practices associated with establishing forest management units (stands), weed control, intermediate thinning, and final harvest. Effects of IFM on vertebrate diversity are indirect through habitat modification. Terrestrial vertebrate responses to IFM are species-specific and directly linked to intensity and extent of habitat modification. Shorter crop tree rotations compress successional stages and limit development and recruitment of mature forest structures (e.g., snags, den/roost trees, coarse woody debris). During stand establishment, increased intensification of site preparation and weed control tends to result in lower vertebrate diversity. Generally, vertebrate

“…For example, rodent, herpetofauna, and avian richness and diversity were either unaffected by intercropping switchgrass, or converged to that of pine plantations by 3 years after switchgrass establishment (Marshall et al , Homyack et al , Loman et al ). Further, the ecological role and trophic position of omnivorous white‐footed mice was not affected by intercropping a potential food source, switchgrass (Briones et al ). Similarly, harvesting of residual woody biomass did not have strong negative effects on either abundance or diversity of herpetofauna or rodents (Marshall et al , Homyack et al ).…”

Intensively managed forests in the southeastern United States are a potential source of cellulosic bioenergy and, as conversion technologies improve and demand increases, a greater land area may be required to produce biofuel feedstocks. However, responses of wildlife to forest-based biofuel production are largely unknown. We examined the 4-year response of rodent populations and assemblages to a range of biofuel production regimes, including harvesting residual woody debris and intercropping switchgrass (Panicum virgatum), in an intensively managed loblolly pine (Pinus taeda) forest in eastern North Carolina, USA. We investigated abundance, demography, and community response of rodents in a randomized and replicated field experiment using mark-recapture techniques during 2009-2012. Whereas removal of downed woody biomass did not affect abundance, diversity, or demography of rodents, we detected species-specific effects of incorporating switchgrass. After switchgrass was well established, invasive house mice (Mus musculus) were most abundant in plots with switchgrass. In contrast, white-footed mice (Peromyscus leucopus) were commonly captured in plots without switchgrass and other rodents were not affected by biofuel treatments. Across the study, natural succession exerted greater effects on rodent species and the rodent community than biofuel production regimes. As remaining logs and stumps decay and become limiting, downed wood may become more important to rodents. Our results indicate that intercropping switchgrass and harvesting residual woody material had limited effects on rodents in the Coastal Plain of North Carolina, USA within 4 years of stand establishment.

“…Abundance of white-footed mice (Peromyscus leucopus) has been negatively correlated with grass cover while cotton rat (Sigmodon hispidus) captures have been positively correlated with grass cover (Marshall et al, 2012;Mengak and Guynn, 2003). A previous study investigating functional role of white-footed mice in a switchgrass intercropped in a pine system in North Carolina, USA found that there were no differences in carbon or nitrogen isotope signatures between white-footed mice in switchgrass intercropped plots and pine plantation plots, suggesting no change in their functional role (Briones et al, 2013). In established switchgrass intercropped plots, rodent evenness and diversity were lower than in equal aged pine plantation plots (King et al, 2014).…”

“…However, there is a potential for further change as forest succession continues in the intercrop and control treatment plots (Loman et al, 2014). There is a need for research on effects of planting switchgrass on biodiversity, particularly in intercropped stands (Riffell et al, 2012), because most studies that have examined effects of switchgrass on biodiversity have both compared switchgrass to row crops and native grasslands (Fletcher et al, 2010) and investigated effects on grassland birds and herpetofauna Loman et al, 2014) rather than mammals (but see Briones et al, 2013;Homyack et al, 2014;King et al, 2014;Marshall et al, 2012).…”
