“…This study confirms that PL are more species-rich (especially of vascular plants) than UM and OG stands (Table 2; [80]), but this is mostly based on the high diversity of vascular plants, which is not the case for bryophytes (Table 2; [28]). The establishment of PL was comparable to large-scale and high-intensity disturbance of recultivation favoured by light-demanding vascular plants (Table 3; [33,34]), while the DCA analysis (Figure 3a,b) indicated that the dominant species of UM and OG stands favoured semi-open conditions (mid-part of the light gradient in Figure 3a,b; [96][97][98]) formed as a result of forest selfthinning. Some older sites with clearer vertical structures contained more shade-tolerant late successional species, such as Oxalis acetosella [99] and Mercurialis perennis (Figure 3a,b).…”

Forest plantations, which have a simplified structure and composition, are becoming more frequent, raising concerns regarding their contribution to biological diversity in highly managed landscapes. The biological value of a stand has been related to stand age, although stand properties, which are often intercorrelated with it, yet are manageable, might be of primary importance. The relationships between stand properties (age, structure and composition) and ground cover vegetation, as a proxy for biological value, were assessed in Norway spruce stands with contrasting land use history (low-density plantations on former agricultural land, unmanaged and old-growth stands) in Latvia. The ground flora differed according to land use history of the stands. The principal gradients of ground cover vegetation were related to the degree of deciduous admixture in the tree stand, stand vertical heterogeneity (multi-layer; density and height of the understorey), light, age and site fertility. However, the plantations were more species-rich and diverse, appearing as promising in terms of biological diversity in intensively managed sites (especially periurban forests). The observed relationships between ground cover vegetation and stand characteristics suggest that diversification of the stand structures in plantations might reduce the recovery time of ground cover vegetation, contributing to the ecosystem services provided under intensifying management and disturbances.

“…More recent soil formation processes indicate the proclivity of nutrient rich anthrosols (Howard, 2017) that are result of historical agriculture on the site (likely from the application of manure fertilizers). This is distinct from the anthrosols associated with typical Garry Oak ecosystems which are often shallower, have excessive drainage (Roemer, 1972(Roemer, , 1993, and are nitrogen poor (Klinka et al, 1989).…”

Pop-up restoration in colonial contexts: applying an indigenous food systems lens to ecological restoration

As environmental injustices and their disproportionate harms to Indigenous communities are increasingly acknowledged, restoration strategies are being deployed widely by environmental NGOs, resource extraction industries, and government agencies. The inclusion of Indigenous communities and their knowledges in restoration efforts are often considered progress in the pursuit of ecological reconciliation. However, in some cases we have observed a lack of meaningful progress as settler colonial prescriptions for land-healing can eschew efforts to decolonize ecological restoration — what we have labeled “pop-up restoration.” We consider two restoration efforts underway in St’at’imc and Quw’utsun territories (Canada) and contrast them with what we are learning alongside the communities’ own values and efforts to reclaim and revitalize food systems throughout forest, wetland, and grassland systems. Utilizing culturally appropriate pathways, we then evaluate how applying an Indigenous Food Systems lens to ecological restoration may provide a framework to remedy pop-up restoration, confronting settler colonial aspirations to transform Indigenous homelands while asserting justice in ecological restoration contexts.

“…Ericaceous species were false azalea ( Menziesia ferruginea ; Family Ericaceae) and two blueberry species that were pooled due to difficulty in distinguishing between them in the absence of flowers or fruits (Pojar & MacKinnon, 1994): Vaccinium ovalifolium and V. alaskaense ; Family Ericaceae. Ericaceous species are generally found in soils with poor or average nutrient availability, and false azalea has been shown to be more common on streams with a lower abundance of spawning salmon (Douglas et al., 1999b; Hocking & Reynolds, 2011; Klinka et al., 1989).…”

“…Nitrogen indicator species were false lily‐of‐the‐valley ( Maianthemum dilatatum ; Family Asparagaceae) and salmonberry ( Rubus spectabilis ; Family Rosaceae). These species thrive in nutrient‐rich soils, and are known to grow more frequently on streams with a high abundance of spawning salmon (Douglas et al., 1999a, 2009; Hocking & Reynolds, 2011; Klinka et al., 1989).

Nutrients from spawning salmon influence leaf area, tissue density, and nitrogen‐15 in riparian plant leaves

Nutrient subsidies have significant impacts on ecosystems by connecting disjunct habitats, often through long‐distance animal migrations. Salmon migrations on the North Pacific coasts provide these kinds of nutrient subsidies from senescent fish at the end of their life cycle, which can have significant ecological effects on terrestrial species. This can include impacts on individuals, populations, and communities, where shifts in community composition towards plant species that indicate nitrogen‐rich soils have been documented. We investigated the effects of variation in salmon spawning density on the leaf traits of four common riparian plant species on the central coast of British Columbia, Canada. We found that all plant species had higher foliar salmon‐derived nitrogen on streams with a higher spawning density. Three of the four species had larger leaves, and one species also had higher leaf mass per area on streams with more salmon. However, we found no differences in leaf greenness or foliar percent nitrogen among our study streams. These results demonstrate that nutrient subsidies from spawning salmon can have significant impacts on the ecology, morphology, and physiology of riparian plants, which lends support to a mechanism by which certain plants are more common on productive salmon streams.
