Effects of natural resource development on the terrestrial biodiversity of Canadian boreal forests

et al. 2014

Much of Canada's terrestrial biodiversity is supported by boreal forests. Natural resource development in boreal forests poses risks to this biodiversity. This paper reviews the scientific literature to assess the effects of natural resource development on terrestrial biodiversity in Canadian boreal forests. We address four questions: (1) To what extent have Canadian boreal forests changed due to natural resource development? (2) How has biodiversity responded to these changes? (3) Will the biodiversity of second-growth forests converge with that of primary boreal forests? (4) Are we losing species from boreal forests? We focus on trees, understory plants, insects, fungi, selected mammals, and songbirds because these groups have been most studied. We review more than 600 studies and found that changes in community composition are prevalent in response to large-scale conversion of forest types, changes in stand structures and age distributions, and altered landscape structure resulting from forest management and habitat loss associated with other developments such as oil and gas, hydroelectric, and mining. The southern boreal forest has been more highly impacted than the north due to more extensive forest management and the cumulative effects of multiple forms of development. There is abundant evidence that most species are not in danger of being extirpated from the boreal forest due to these anthropogenic changes. A few species, including woodland caribou (Rangifer tarandus) and grizzly bear (Ursus arctos), have, however, undergone long-term range contractions. Significant gaps in our ability to assess the effects of natural resource development on biodiversity in the boreal zone are the lack of long-term spatial and population data to monitor the impact of forest changes on ecosystems and species.Résumé : Une bonne partie de la biodiversité du Canada se retrouve en forêt boréale. Le développement des ressources naturelles dans des forêts boréales présente des risques pour cette biodiversité. Les auteurs présentent une revue de la littérature pour évaluer les effets du développement des ressources naturelles sur la biodiversité terrestre dans les forêts boréales canadiennes. Ils ont soulevé quatre questions : (1) jusqu'à quel point les forêts boréales canadiennes se sont vues modifiées par le développe-ment des ressources naturelles ? (2) Comment la biodiversité a-t-elle réagi à ces changements ? (3) Y aura-t-il convergence de la biodiversité des forêts de seconde venue avec celle des forêts boréales primaires ? (4) Subissons-nous des pertes d'espèces en forêts boréales ? Les auteurs se sont intéressés en particulier aux arbres, aux plantes de sous-bois, aux insectes, aux champignons, à des mammifères et oiseaux chanteurs sélectionnés, car ces groupes ont été les plus étudiés. Ils ont suivi plus de 600 espèces et ont constaté que les changements de composition prévalent en réaction à des modifications à grande échelle des types forestiers, des changements de la structure, des classes d'âge, des modifications aux ...

White pines, Ribes, and blister rust: a review and synthesis

2010

View full text Add to dashboard Cite

For over a century, white pine blister rust (Cronartium ribicola) has linked white pines (Strobus) with currants and gooseberries (Ribes) in a complex and serious disease epidemic in Asia, Europe, and North America. Because of ongoing changes in climate, societal demands for forests and their amenities, and scientific advances in genetics and proteomics, our current understanding and management of the white pine blister rust pathosystem has become outdated. Here, we present a review and synthesis of international scope on the biology and management of blister rust, white pines, Ribes, and other hosts. In this article, we provide a geographical and historical background, describe the taxonomy and life cycle of the rust, discuss pathology and ecology, and introduce a series of invited papers. These review articles summarize the literature on white pines, Ribes, and blister rust with respect to their status, threats, and management through genetics and silviculture. Although the principal focus is on North America, the different epidemics in Europe and Asia are also described. In the final article, we discuss several of the key observations and conclusions from the preceding review articles and identify prudent actions for research and management of white pine blister rust.

“…White pine blister rust hazard is mapped at a regional scale for distinguishing among broad geographic zones that vary in the environmental risk of supporting an infestation. Such maps are available for the Northeastern and Lake States, Quebec, and Ontario (C harlton 1963; V an A rsdel 1965a,b; L avallée 1974, 1986b; A nderson et al. 1980; G ross 1985; W hite et al.…”

“…Sites in low hazard zones usually require no special management for blister rust; whereas in the moderate and high zones, blister rust control or deferred investment in white pine are usually advisable (V an A rsdel 1961, 1964). For example, low hazard zones in Ontario and Quebec are narrow and limited to southern areas where white pine can be grown without blister rust control (G ross 1985; L avallée 1986b). In the moderate hazard zone, sanitation and preventative pruning provide for adequate survival of plantation white pine (L aflamme et al.…”

Silvicultural approaches for management of eastern white pine to minimize impacts of damaging agents

2010

View full text Add to dashboard Cite

Since the arrival to North America of Cronartium ribicola, management of eastern white pine has been driven by the need to avoid the actual or, in many areas, the perceived damage caused by white pine blister rust. Although white pine has lost much of its former dominance, it remains a valuable species for biotic diversity, aesthetics, wildlife habitat and forest products. Understanding its silvics and damaging agents provides a sound basis for the silvicultural activities of site selection, regeneration and stand tending. The species can be successfully grown in many locations despite herbivory, competition, white pine weevil and blister rust. Forest managers can minimize damage by applying knowledge of local conditions (climate, soils, physiography and vegetation) to hazard assessment, site selection and preparation, vegetation management, and pruning. With appropriate management and a long-term commitment, many eastern forests can be beneficially reforested to eastern white pine with little impact from blister rust and other damaging agents.
