“…Historic and current land use practices in Alberta could reduce amounts of habitat where Canada Warblers are frequently detected (Schneider et al 2003, Mahon et al 2014). An estimated 32% of deciduous trees and 50% of older age classes of deciduous trees have been lost in Alberta compared with a landscape without human development (ABMI 2012).…”

ABSTRACT. Understanding factors that affect the distribution and abundance of species is critical to developing effective management plans for conservation. Our goal was to quantify the distribution and abundance of Canada Warbler (Cardellina canadensis), a threatened old-forest associate in Alberta, Canada. The Canada Warbler has declined across its range, including in Alberta where habitat loss and alteration from urban expansion, forestry, and energy development are changing the forest landscape. We used 110,427 point count survey visits from 32,287 unique survey stations to model local-level (150-m radius circular buffers) and stand-level (564-m radius circular buffers) habitat associations of the Canada Warbler. We found that habitat supporting higher densities of Canada Warblers was locally concentrated yet broadly distributed across Alberta's boreal forest region. Canada Warblers were most commonly associated with older deciduous forest at the local scale, particularly near small, incised streams, and greater amounts of deciduous forest at the stand scale. Predicted density was lower in other forest types and younger age classes measured at the local scale. There was little evidence that local-scale fragmentation (i.e., edges created by linear features) influenced Canada Warbler abundance. However, current forestry practices in the province likely will reduce the availability of Canada Warbler habitat over time by cutting old deciduous forest stands. Our results suggest that conservation efforts aimed at Canada Warbler focus on retaining large stands of old deciduous forest, specifically stands adjacent to streams, by increasing the width of deciduous retention buffers along streams during harvest and increasing the size and number of old forest residual patches in harvested stands.Besoins régionaux en matière d'habitat d'une espèce inscrite sur la liste nationale d'espèces en péril, la Paruline du Canada (Cardellina canadensis), en Alberta, Canada RÉSUMÉ. La compréhension des facteurs qui influent sur la répartition et l'abondance d'une espèce est importante si l'on veut élaborer des plans de gestion efficaces pour sa conservation. L'objectif de notre étude était de quantifier la répartition et l'abondance de la Paruline du Canada (Cardellina canadensis), une espèce menacée associée aux forêts âgées en Alberta, Canada. Les effectifs de la Paruline du Canada ont diminué dans l'ensemble de son aire, y compris en Alberta où la perte et la modification d'habitat attribuables à l'étalement urbain, aux pratiques forestières et aux activités de développement énergétique modifient le paysage forestier. Nous avons utilisé 110 427 dénombrements à partir de 32 287 stations d'écoute afin de modéliser l'association de la Paruline du Canada avec l'habitat à l'échelle locale (rayon de 150 m autour de la station) et à celle du peuplement (rayon de 564 m autour de la station). Nous avons trouvé que les milieux qui hébergeaient les densités les plus élevées de Paruline du Canada étaient concentrés localement, mais aussi t...

“…Meanwhile, some provincial forests are being heavily impacted by oil and gas production. For example, simulations for a study area in northeastern Alberta suggest that the energy and forestry industries could increase the density of human-origin edge from 1.8 to 8.0 km/km 2 (Schneider et al 2003).…”

Can hybrid poplar save industrial forestry in Canada?: A financial analysis in Alberta and policy considerations

Intensifying forest management has the potential to alleviate pressures of competing land uses, maintain global competitiveness in the face of increasing exotic plantations, and increase the value of the boreal forest resource. Yet, such initiatives have largely been stymied in Canada's boreal regions because intensive forest management of native tree species is not financially viable. The yield curve estimation and financial analysis conducted in this paper, however, suggests intensive management of hybrid poplar in Alberta could be financially viable. The financial viability of such initiatives will depend heavily on the policies that governments use -such as priority-use zoning -to encourage or discourage such trends. But before reforming policy, decision-makers must trade off the environmental implications of industrial plantations of exotic species with the potential gains from priority-use zoning.Key words: soil expectation value, optimal economic rotation, hybrid poplar, priority-use zoning, intensive forest management RÉSUMÉ L'intensification de l'aménagement forestier pourrait réduire les pressions compétitrices exercées dans un territoire donné, maintenir la compétitivité globale face aux plantations exotiques de plus en plus importantes et accroître la valeur de la ressource forestière boréale. Malgré tout, de telles initiatives ont été en grande partie vouées à l'échec dans les régions nordiques du Canada parce que l'aménagement forestier intensif des espèces indigènes s'avère non financièrement viable. L'estimation du rendement et l'analyse économique réalisées dans cet article, laissent entendre cependant que l'aménage-ment intensif de peupliers hybrides en Alberta pourrait être économiquement rentable. La viabilité économique de telles initiatives dépendra principalement des politiques utilisées par le gouvernement comme le zonage prioritaire du territoire, pour encourager ou décourager ce genre de tendance. Mais avant de reformer les politiques, les preneurs de déci-sions doivent trouver un équilibre entre les implications environnementales des plantations industrielles d'espèces exotiques et les gains potentiels tirés du zonage prioritaire du territoire.Mots clés : valeur attendue du sol, cycle économique optimal, peuplier hybride, zonage prioritaire du territoire, aménage-ment forestier intensif

“…These activities have affected about 400,000 km 2 of extratropical peatlands, equivalent to 12% of the 3.46×10 6 km 2 of boreal and subarctic peatland 13 . Linear features such as roads and seismic lines also impede peatland hydrology 14 , and are found at densities of 1.8 km km − 2 in northern Alberta 15 . If current economic practices are continued, linear features in this region are expected to reach 8 km km − 2 by the next century 15 , probably becoming a dominant land use change affecting Canadian peatlands.…”

Experimental drying intensifies burning and carbon losses in a northern peatland

For millennia, peatlands have served as an important sink for atmospheric Co 2 and today represent a large soil carbon reservoir. While recent land use and wildfires have reduced carbon sequestration in tropical peatlands, the influence of disturbance on boreal peatlands is uncertain, yet it is important for predicting the fate of northern high-latitude carbon reserves. Here we quantify rates of organic matter storage and combustion losses in a boreal peatland subjected to long-term experimental drainage, a portion of which subsequently burned during a wildfire. We show that drainage doubled rates of organic matter accumulation in the soils of unburned plots. However, drainage also increased carbon losses during wildfire ninefold to 16.8 ± 0.2 kg C m − 2 , equivalent to a loss of more than 450 years of peat accumulation. Interactions between peatland drainage and fire are likely to cause long-term carbon emissions to far exceed rates of carbon uptake, diminishing the northern peatland carbon sink.
