Forests are increasingly affected by natural disturbances. Subsequent salvage logging, a widespread management practice conducted predominantly to recover economic capital, produces further disturbance and impacts biodiversity worldwide. Hence, naturally disturbed forests are among the most threatened habitats in the world, with consequences for their associated biodiversity. However, there are no evidence-based benchmarks for the proportion of area of naturally disturbed forests to be excluded from salvage logging to conserve biodiversity. We apply a mixed rarefaction/extrapolation approach to a global multi-taxa dataset from disturbed forests, including birds, plants, insects and fungi, to close this gap. We find that 75 ± 7% (mean ± SD) of a naturally disturbed area of a forest needs to be left unlogged to maintain 90% richness of its unique species, whereas retaining 50% of a naturally disturbed forest unlogged maintains 73 ± 12% of its unique species richness. These values do not change with the time elapsed since disturbance but vary considerably among taxonomic groups.

“…With agricultural intensification, fields have become larger, semi-natural habitats have declined and the farmland landscape has become more homogenous (Ihse, 1995, Tscharntke et al, 2005. However, farmland species do not occur exclusively on farmland (Söderström, 2009, Stjernman et al, 2013, Żmihorski et al, 2016: mosaic landscapes of other open habitats and forested areas are also important for many species (Pitkänen & Tiainen, 2001, Żmihorski et al, 2019. A growing number of studies have shown that human-made habitat such as forest clear-cuts have potential as suitable habitat for farmland species (see review by Ram et al, 2020).…”

“…In addition, while several studies have evaluated the effects of post-fire salvage logging on birds in western conifer forests (e.g., Haggard and Gaines 2001, Hutto and Gallo 2006, Saab et al 2007, Cahall and Hayes 2009, Rost et al 2013, most have focused on a narrow subset of the bird community. As the annual area burned and the proportion burned at high severity increase (Steel et al 2018), it is also important to evaluate more comprehensively how the bird community responds to salvage logging, in particular mature forest species (Lee et al 2013;Zmihorski et al 2019). The majority of post-fire salvage logging studies have also focused on single fires, and thus, the resulting burn patterns, fire size, landscape context, and post-fire management directives may be unique to that particular fire (Rost et al 2013).…”

Short-term effects of post-fire salvage logging intensity and activity on breeding birds in the Sierra Nevada Mountains, USA

Background Salvage logging of fire-killed trees in western US conifer forests has been shown to negatively affect many wildlife species, but there are few quantitative studies from the Sierra Nevada, CA. Salvage intensity (i.e., the proportion of fire-killed trees removed during logging activities) has also rarely been measured; instead, most studies track the presence/absence of salvage activities. We explored the effects of post-fire salvage on the breeding bird community following the 2012 Chips and 2013 Rim fires using a before-after control-impact sample design, and modeled species responses to salvage including a test of whether species responded to salvage intensity or the presence of salvage activities as a whole. Results Salvage operations removed an average of 71% of the snag basal area in the Chips Fire and 64% in the Rim Fire within 50 m of our salvaged survey locations. Bird species responses to salvage in both fires were largely non-significant or negative (Chips: 11 negative, 4 positive, 19 non-significant; Rim: 13 negative, 4 positive, 20 non-significant). Statistical support for the salvage intensity vs. salvage activity models was split evenly among all species. Positive salvage responders in both fires included species adapted to open habitats and seed consumers, while a wide variety of species, including woodpeckers, species associated with open and dense mature forest, and some shrub nesters, responded negatively to salvage. We also evaluated five salvage prescription scenarios based on snag basal area, salvage intensity, and area treated to determine whether any combination could minimize the negative effects on the salvage-sensitive species yet retain the same salvage yield. The scenarios with the smallest area targeted with high-intensity salvage saw the smallest declines in abundance and diversity, but nearly all scenarios reduced both measures. Conclusions No combinations of salvage intensity and distribution from among the scenarios we explored were able to fully mitigate the negative effect on the bird community; however, the magnitude of declines in abundance and diversity was smaller than expected, and the majority of the species analyzed had a non-significant response. We recommend targeting salvage activities in the Sierra Nevada to those locations where snags pose a safety issue or where reforestation is most needed to conserve this fire-adapted bird community.
