“…The reduction of SM RA with increasing opening size was primarily a function of an increase in the abundance of other competing species (Table 2; Figure 3). Arseneault et al (2011) observed similar results following the first 10 years after implementing an irregular shelterwood system in an Acadian hardwood forest in Maine.…”

“…Our results seem to indicate that a variety of harvest treatments can successfully regenerate tolerant species, but a number of other factors must be taken into account including the presence of the species in the overstory, presence of other competing species, and time since harvest. It can be very difficult to assess success of natural regeneration during the first decade following treatment (Arseneault et al, 2011;Morrissey et al, 2010). A variety of species can regenerate following a disturbance of any size (Arseneault et al, 2011).…”

A variety of species can regenerate following a disturbance of any size (Arseneault et al, 2011). Silvicultural monitoring programs that target specific points in time may result in incorrect decisions regarding silviculture success or failure (Kershaw Jr. & VanDamme, 2012), especially if the monitoring techniques are adapted from plantation monitoring programs.…”

“…When managing mixed-species stands, harvesting has the potential to alter the species favored as regeneration (Leak & Filip, 1977;Carlson & Groot, 1997;Arseneault et al, 2011). However, predicting which tree communities will arise following harvesting remains a difficult task (Roberts & Gilliam, 1995;Gould et al, 2005), especially in mixed-species stands (Bataineh et al, 2013).…”

“…with beech bark disease (Taylor et al, 2013) reduce direct comparability of these studies to the Acadian Forest where these issues are more of a concern (Arseneault et al, 2011;Morin et al, 2007). The reduction of shade-tolerant hardwood species within the Acadian Forest (Loo & Ives, 2003;Salonius, 2007) calls into question presently used harvesting methods and their effects on the establishment and recruitment of these tree species, yet there is currently limited local empirical knowledge to support changes in forest management policy or practices (Floyd et al, 2012).…”

In the Acadian Forest Region of northeastern North America, forest managers are under increasing public pressure to restore the forest to a more historic, natural condition by reducing in clearcutting and promoting partial-cut treatments that more closely emulate historic, local natural disturbance regimes. However, although numerous studies on the effects of partial-cutting on forest regeneration response have been conducted in surrounding temperate and boreal forest ecosystems, there are few studies that directly explore responses to various forms of harvesting within the Acadian Forest ecosystem, with its unique mixture of northern hardwoods and boreal forest species. Here, we conducted one of the first retrospective studies on forest regeneration following a variety of harvesting methods in the Acadian Forest using univariate and multivariate regression trees to assess regeneration response in 50 naturally-regenerating, harvested forest sites in New Brunswick, Canada. Our study shows that regeneration was highly influenced by harvest type, overstory composition, and environmental conditions as reflected by ecoregion classification. Canopy opening size (as controlled by harvest method) significantly influenced the dominance of regenerating species. The presence of conspecific overstory trees increased the likelihood of their regeneration following disturbance, supporting the direct-regeneration hypothesis, especially for species with limited seed dispersal (e.g., sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.). Despite reported problems elsewhere in eastern North America, neither American beech nor balsam fir (Abies balsamea (L.) Mill.) constituted significant competition for the desired species on a broad scale, but the presence of beech was a significant deterrent for yellow birch (Betula alleghaniensis Britt.).

Prescribed fire and partial overstory removal alter an acorn–rodent conditional mutualism

In eastern North America, oak (Quercus) regeneration failure has spurred management using silvicultural approaches better aligned with the autecology of oaks. In particular, shelterwood harvests can create favorable intermediate light conditions for oak establishment and prescribed fire is predicted (by the oak–fire hypothesis) to favor oak regeneration. These approaches substantially modify forest structure and may affect crucial trophic interactions including the conditional mutualism between oaks and granivorous rodents that scatterhoard acorns, which shifts along a continuum from antagonistic to mutualistic depending on external factors. We investigated how overwinter survival and dispersal of northern red oak (Quercus rubra) acorns were influenced by location within or outside of group shelterwood harvests (small canopy gaps created throughout an intact forest stand) with and without prescribed fire. We conducted two concurrent experiments to test (1) dispersal and survival of acorns presented on the forest floor and (2) acorn pilferage rates from caches that mimic squirrel scatterhoards in shelterwood gap/group interiors, edges, and the uncut forest matrix in burned and unburned forest stands. In both experiments, acorn survival was generally higher in burned than unburned stands. Acorn survival from forest floor presentations was higher in the unharvested forest matrix than harvest gap interiors; however, there was no effect of proximity to harvest gaps on survival of cached acorns. Survival of cached acorns was associated with understory vegetative cover (−), coarse woody debris cover (−), and distance to nearest tree (+), but uncorrelated with canopy cover above the cache. Our results suggest that reduced understory cover following prescribed fire may increase perceived habitat riskiness for granivores resulting in higher acorn survival up to 2 yr post‐fire. These findings unify the oak–fire and oak–granivore conditional mutualism hypotheses, and suggest that the environmental conditions following prescribed fire and group shelterwood harvests may shift the oak–granivore conditional mutualism in a direction beneficial for oak regeneration.
