“…3b). Southern pine beetle rarely impacted pines in oak-dominated stands, and tree mortality was lower in mixedwood stands, a pattern also documented by Heuss et al (2019) in New York, where mortality averaged 60% of total basal area in pitch pine-dominated stands, versus 50% and 35% in unmanaged and managed pine-oak stands, respectively.…”

“…Southern pine beetle is native to the southeastern USA, south through Mexico, and west to Texas, but recently its range has extended northward on the Atlantic coastal plain into New Jersey and Long Island, New York, and it has been detected further north in forests dominated by pitch pine (P. rigida Mill.) (Weed et al 2013;Clark et al 2017;Dodds et al 2018;Heuss et al 2019). It has also expanded westward into southern Missouri, Illinois and Ohio.…”

“…Recent infestations of southern pine beetle in the mid-Atlantic region have significant impacts on ecosystem functioning and carbon dynamics of pine-dominated stands (Fig. 3b; Heuss et al 2019;Clark et al 2020). Projected leaf area and canopy nitrogen content of remaining trees and saplings in infested stands in New Jersey were less than half of preinfestation values three to five years following extensive pine mortality (Clark et al 2017;.…”

“…In infested stands, standing dead trees and coarse woody debris increased simulated annual ecosystem respiration up to 1.2 times the values for uninfested areas, and increased heterotrophic respiration will further depress NEP (Renninger et al 2014;Clark et al 2018). Because reduction in GEP and increased ecosystem respiration are largely proportional to pine mortality, net productivity and NEP will recover relatively rapidly in mixedwood stands that experience lower levels of damage and mortality (Heuss et al 2019;Clark et al 2020).…”

Mixedwood stands are composed of hardwoods and softwoods, with neither comprising greater than 75-80% of basal area or aboveground biomass. By conferring associational resistance and greater resilience to forests when stressed or disturbed, the more diverse composition of mixedwood stands contributes to forest health. We analyzed three examples where mixedwood stands are more resistant to insect infestations in eastern North America. In balsam fir and spruce forests, susceptibility and vulnerability to spruce budworm infestations is reduced with increasing hardwood density. In mid-Atlantic oak-dominated forests, oak mortality following gypsy moth infestations was much greater in oak-dominated than in oak-pine mixedwoods, while pine mortality during southern pine beetle infestations was greater in pine-dominated than in oak-pine mixedwoods. Overall, mixedwood stands have greater resistance to infestations of defoliators and bark beetles and recover more rapidly from disturbances, reducing economic losses associated with tree mortality and mitigating short-term impacts to ecosystem functioning resulting from insect damage, especially carbon sequestration. Finally, we discuss challenges and opportunities for mixedwood management to minimize insect damage. Management strategies that incorporate mixedwood stands may provide better continuity in supply of forest products and ecosystem services in the face of projected increases in insect infestations associated with changing climate.

Impact assessment of coastal marine range shifts to support proactive management

Climate change is reshuffling Earth’s biota as species shift their current ranges to track suitable conditions, often in response to increasing habitat temperatures. While redistribution may be necessary for species persistence, there can also be impacts on existing communities upon arrival of novel, range‐shifting species. Anticipating the beneficial versus deleterious impacts of range‐shifting species is essential for determining whether active management is needed, which could include implementation of strategies from facilitation (eg managed relocation) to suppression (eg prevention and control). We used an impact assessment protocol developed for invasive species to evaluate potential consequences of range shifts in coastal marine ecosystems of North America. Our review demonstrates how invasion impact assessment combined with species vulnerability assessment could support decisions about management of range shifts. We found that ~50% of these shifting coastal species have had negative impacts in their expanded ranges. The importance of proactive management is likely to increase as the number and extent of range shifts accelerates.
