Triage for conserving populations of threatened species: The case of woodland caribou in Alberta

Richard R. Schneider, Grant Hauer, W.L. (Vic) Adamowicz, Stan Boutin

Prioritization of conservation efforts for threatened and endangered species has tended to focus on factors measuring the risk of extirpation rather than the probability of success and cost. Approaches such as triage are advisable when three main conditions are present: insufficient capacity exists to adequately treat all patients, patients are in a critical state and cannot wait until additional capacity becomes available, and patients differ in their likely outcome and/or the amount of treatment they require. The objective of our study was to document the status of woodland caribou (Rangifer tarandus) herds in Alberta, Canada, with respect to these three conditions and to determine whether a triage approach might be warranted. To do this we modeled three types of recovery effort – protection, habitat restoration, and wolf control – and estimated the opportunity cost of recovery for each herd. We also assessed herds with respect to a suite of factors linked to long-term viability. We found that all but three herds will decline to critical levels (<10 animals) within approximately 30 years if current population trends continue. The opportunity cost of protecting all ranges by excluding new development, in terms of the net present value of petroleum and forestry resources, was estimated to be in excess of 100 billion dollars (assuming no substitution of activity outside of the ranges). A habitat restoration program applied to all ranges would cost several hundred million dollars, and a provincial-scale wolf control program would cost tens of millions of dollars. Recovery costs among herds varied by an order of magnitude. Herds also varied substantially in terms of their potential viability. These findings suggest that woodland caribou in Alberta meet the conditions whereby triage should be considered as an appropriate conservation strategy.

THE IMPLICATIONS OF ALTERNATIVE GROWTH PATTERNS ON INFRASTRUCTURE COSTS

IBI Group

EXECUTIVE SUMMARY Purpose of Report Calgary has seen record levels of growth over the last few years and population and economic growth is expected to continue in the future. Over the next 60 years the population in the city itself is expected to grow from approximately 1 million to 2.3 million persons, with another 0.5 million people in the surrounding region. This level of growth offers the opportunity, and the need, to shape the future land use and transportation patterns of Calgary. Plan It Calgary has commissioned this study to assist in development of an integrated plan for land use and transportation. It examines the infrastructure implications of two growth patterns. The Dispersed Scenario reflects current trends and the continuation of current city policies, while the new Recommended Direction intensifies jobs and population in specific areas of the city, and links them with high-quality transit services. The types of infrastructure investigated in this report are transportation (roads and transit), water and sewer services, police, fire, parks, recreation centres and schools. Key Findings • The land required for Plan It Calgary’s Recommended Direction is 25% smaller than the Dispersed Scenario (which reflects current policy and trends). • The cost to build Recommended Direction is 33% less expensive than the Dispersed Scenario. • The Recommended Direction would be less expensive to operate and maintain over the next 60 years than the Dispersed Scenario. • The cost to build, maintain and replace aging streets has the largest impact when comparing costs between the two growth patterns. Reduced greenfield growth in the Recommended Direction will result in a 36% cost savings for new streets compared to the Dispersed Scenario, and will also reduce maintenance and replacement costs. • Enhanced Primary Transit service proposed in the Recommended Direction would actually be less expensive to build than extending transit to suburban communities in the Dispersed Scenario. Increased transit ridership in Recommended Direction, which provides double the service compared to the Dispersed Scenario, means that it would cost approximately the same to operate transit in both growth patterns. • Reduced greenfield growth in Recommended Direction will result in a 55% cost savings for water and wastewater systems compared to the Dispersed Scenario. There would be no net difference in costs for the existing parts of Calgary since replacement of water and wastewater systems will be required as infrastructure ages. Significant intensification of existing areas and growth in new greenfield communities could both trigger the need to upgrade existing systems.

Ecosystem Goods and Services Southern Alberta: A Framework for Assessing Natural Asset Condition

02 Planning + Design Inc.

Society’s well-being, to a large extent, is underpinned by a wide range of Ecosystem Goods and Services (EGS) that are provided by natural assets. These include: provision of clean air and water;-- water storage and flood control;-- carbon sequestration and greenhouse gas regulation;-- pollination of crops and native vegetation; and-- the fulfillment of cultural, spiritual, and recreational needs.-- The transfer of EGS to future generations is compromised if land use planning does not prevent the degradation and loss of natural assets in the landscape. Alberta’s new Land Use Framework (LUF) provides opportunities to address interactions between society, nature, and EGS to promote sustainable development. The ecosystem services concept frames land use planning and natural resource management issues to explicitly link ecosystems and human welfare. This provides decision makers with more information to help them achieve an appropriate balance between the many costs and benefits of land use decision-making. Building on previous work, this report contributes to this process by identifying indicators of natural asset conditions, linking these indicators to ecosystem services, and suggesting a methodology for assessment in a land use planning context. Several key findings should be highlighted from the literature review. One prevalent theme suggests that focusing management efforts on provisioning services (i.e., crops, timber, fossil fuels) often results in tradeoffs where other ecosystem services are degraded as a consequence. Another key theme is the importance of multi-scale approaches to ecosystem service assessments (e.g., regional, landscape, watershed, site). A third key finding is the lack of available biophysical methodologies to quantify ecosystem service magnitudes, as most quantification studies utilize economic valuation techniques. In addition, appropriate thresholds and targets are rarely identified through scientific research, although some science-based targets have been identified for wetland cover (3% to 7% of a watershed), impervious surfaces (<10% of a watershed), riparian buffer widths, and road densities. In most cases, target-setting requires integration of science and societal valuation. The landscape context also must be considered when setting targets, as appropriate values often vary considerably throughout a given region. Building on the information gained from the literature review, this report identifies a suite of indicators to assess ecosystem conditions and related services at multiple scales. Six criteria were used to assess the suitability of indicators: comprehensibility for both professionals and the lay public; -- range of applicability to multiple ecosystem services;-- responsiveness to management practices; -- measurability of cost effectiveness; -- ease of integration with existing programs and data; and, -- relevance within land use planning (predictable in scenario modelling --and related to published scientific thresholds).

Moose Alces alces behaviour related to human activity

WIEBKE NEUMANN

The spatiotemporal dynamics of human activity requires a better understanding of the ecological effects on wildlife. This thesis focuses on the behavioural response of a harvested species, moose (Alces alces), to dynamic human activities e.g. hunting and recreation, and to static influences like roads, using experimental and descriptive approaches. Potentially lethal (hunting) and non-lethal (hiking, snowmobiling) activities provoked short-lived increases in moose movement activity and caused spatial displacement. The data suggests a uniform response towards unexpected disturbance and that moose are sensitive to human proximity. Hunting clearly provoked the strongest response. Moose approached by a hunting dog commonly fled, suggesting adjustments in anti-predator behaviour towards a nonnative predator. This may lead to predator facilitation where wolves and human predation co-exist, because the moose’s behavioural response towards one predator possibly increases the predation risk by the other. Unexpectedly, hiking and motordriven (snowmobiling) recreational activity caused a comparable change in moose behaviour. The short-lived response towards dynamic human activities indicates a rather minor impact on moose total energy budget from a single disturbance. Moose seldom crossed roads, but did increasingly so during migration. Roadcrossing sites were aggregated, suggesting well established travel routes and corridors for migratory moose. Moose did not cross roads more often during hunting season. In general, moose little utilized habitats in proximity to roads. Moose-vehicle collisions did not occur where and when moose most commonly cross roads. My results suggest a higher risk to human safety during times of poor visibility and close to urban areas, but not necessarily in the vicinity of forests. For wildlife subject to intensive harvest and sensitive to human proximity, I emphasize the need to include animal behavioural, landscape ecological, political as well as socio-economical aspects for future research concerning human-wildlife interactions. I also recommend future research to combine wildlife movement data from active tracking sensors such as GPS-collars together with collision data to improve conclusions about wildlife movement corridors and traffic risk zones.

Quantifying land use of oil sands production: a life cycle perspective

Sarah M Jordaan, David W Keith and Brad Stelfox

Methods for the inclusion of land use in life cycle assessment are not well established. Here, we describe an approach that compares land disturbance between spatially compact and diffuse activities that contribute to the life cycle of a single product, in this case synthetic crude from Alberta’s oil sands. We compare production using surface mining and in situ extraction technologies. In situ technologies disturb less land per unit of production than surface mining, but the spatial footprint of in situ production is more dispersed—increasing landscape fragmentation—and in situ production requires more natural gas which increases land use due to gas production. We examine both direct and peripheral land use of oil sands development by quantifying land disturbance using a parameterized measure of fragmentation that relies on ‘edge effects’ with an adjustable buffer zone. Using a life cycle perspective, we show that the land area influenced by in situ technology is comparable to land disturbed by surface mining when fragmentation and upstream natural gas production are considered. The results suggest that land disturbance due to natural gas production can be relatively large per unit energy. This method could be applied to other energy developments, for example, a comparison between coal mining and natural gas production when both fuels are used to generate electricity.

Alberta By Design: A Blueprint for an Effective Land-Use Framework

Steve Kennett and Rick Schneider

Alberta is at a turning point with respect to land and resource management. There is a broad consensus among Albertans familiar with land-use issues in the province that the current system of planning and decision-making urgently needs an overhaul. This report, by the Pembina Institute and the Canadian Parks and Wilderness Society, presents a practical and solutions- oriented blueprint for a new Land-Use Framework.

ENVIRONMENTANVIRONMENTAL & RURAL STEWARDSHIP REMUNERATION FOR AGRICULTURE IN MANITOBA

Manitoba Cattle Producers Association

This document is provided to the Government of Manitoba as a recommended roadmap for establishing a province-wide social and ecological goods and services payment program for the agricultural sector in Manitoba. The proposal presented herein is based on the growing international policy consensus that domestic farm policies need to be adjusted to better reflect the multifunctional role of agriculture as not only an economic activity but also as a larger environmental and social activity. This world-wide re-interpretation of agriculture has resulted in the re-instrumentation of domestic agri-environmental and rural development policies internationally, with a decisive turn towards the use of financial incentives to reward agricultural producers for their on-going provision of ecological and social good and services to the remainder of society. The recommended approach is the creation of a Manitoba Environmental and Rural Stewardship Program – a unified provincial policy instrument capable of delivering modular, staged, and ‘trade-green’ remuneration for the multiple public good functions of agriculture which have historically been subject to market failure. Shaped in the context of the experiences and lessons learned from various pilot projects in Canada and the many ecological/social goods and services programs already existing thought the world, the proposed program seeks to optimize the aggregate supply of agricultural commodities, ecological goods and services, and social benefits produced by rural Manitoba. It is MCPA’s view that sufficient information and data are available today to begin the staged transition from the original ALUS pilot project to the adoption of a province-wide stewardship payment program that works for all of agriculture in Manitoba.
