Avoid unnecessary removal of large old-growth trees and snags, which serve as important wildlife habitat (Kalies and Rosenstock 2013); leave some juvenile trees or plant seedlings to promote establishment of new trees (Redmond et al. 2023); use best practices to maintain soil health (e.g., Tomao et al. 2020) including retaining sufficient seed trees and sources of mycorrhizal inoculum (Simard et al. 2021) and limiting pile burning and mastication where possible (Ross et al. 2012); implement landscape- and regional-scale heterogeneity in treatment design (Bradley 2009); and evaluate treatment effectiveness (e.g., McKinney et al. 2022, Davis et al. 2024, Hood et al. 2024), including monitoring local SGCN populations.

Biological Resource Use Climate Change and Severe Weather Natural System Modifications

Assess the synergistic effects between climate change and other threats to SGCN and their habitats (e.g., Friggens et al. 2019, Parks et al. 2019). Incorporate appropriate climate adaptation strategies and frameworks into projects designed to address these synergistic effects. This may include enhancing connectivity (CEQ 2023), facilitating a species’ innate adaptive capacity (Thurman et al. 2022), enhancing genetic diversity (Powell 2023), considering local adaptation (Meek et al. 2023), or considering whether it is most appropriate to resist, accept, or direct ecosystem transformation (Lynch et al. 2021, Stevens et al. 2021). Projects should acknowledge ecosystem dynamism and incorporate indigenous knowledge (e.g., Roos et al. 2022, Eisenberg et al. 2024), nature-based solutions (Warnell et al. 2023), and experimentation (Guiterman et al. 2022) when appropriate.
