DELIVERING UNPOPULAR MESSAGES: Don’t just survive. Succeed!
Lorne Fitch, P. Biol.
We’d all like to deliver popular messages, the ones people want to hear, the positive and uncontroversial ones and those that evoke emotional responses like gratitude, pleasure and warmth. In a perfect world what other messages would there be to deliver? In that other sphere those that listen to messages would be well informed, rational, interested, motivated, knowledgeable and broad-minded. The fact that people, in this world, often don’t display these characteristics is not an indictment against them. It isn’t right, it isn’t wrong; it is just that way. As someone who is going to deliver an unpopular message it is the recognition that some responses are predictable, unsurprising and not totally unjustified. As the deliverer of that message, you are challenging the beliefs, perceptions and opinions of someone. Most people are driven by a combination of beliefs that are largely ill formed, lack crucial information and can be irrational because of other circumstances. There is a lack of time, application of critical thinking and interest to sort through a complex situation, until the message deliverer holds up a mirror forcing people to face the issues. Who wouldn’t be wracked with anxiety, anger or fear with that prospect?

Water Quality Study of Waiparous Creek, Fallentimber Creek and Ghost River
Increased usage of the Ghost -Waiparous basin for random camping and off-highway vehicles (OHVs) has raised concerns among stakeholders that these activities are affecting water quality in the Ghost, Waiparous and Fallentimber Rivers. This report to Alberta Environment attempts to determine whether there is a linkage between these activities and water quality in these three rivers and documents baseline water quality prior to the implementation of an access management plan by the Alberta Government.

An Examination Of The Effects Of Economic Growth On Landscape Features And Processes In Southern Alberta Using ALCES
Terry Antoniuk, Brad Stelfox, and Mark Anielski
Regional-scale modelling examined the long-term cumulative effects of land-use, resource demands, and population increases on the landscape of southern Alberta. The results will help inform the project, Southern Alberta Landscapes: Meeting the Challenges Ahead (SAL), in addressing the increased use of our environment into the future. SAL was launched in 2002 as a cross-Ministry, inter-governmental, strategic planning initiative to examine sustainable development issues in southern Alberta. A Base Case Scenario, which assumed a continuation of current land use practices and business plans, was developed first as a Baseline for comparison with other scenarios. An alternate scenario was then run to test various "What-if" questions. Both scenarios used 2000 for year zero because this was the most recent year for which most data were available for the region.

Road Sediment Production and Delivery: Processes and Management
Lee MacDonald and Drew B.R. Coe
Unpaved roads are often considered to be the predominant sediment source in forested catchments. In steep, wet climates roads can cause a 10- to 300-fold increase in the landslide erosion rate, and this increase is due to the effects of roads on hillslope flow paths and the structural integrity of hillslopes. The proportion of sediment that is delivered to the stream will generally be very high for road-induced failures in hollows and inner gorge landforms, and much lower for planar hillslope failures. The pulsed input of sediment from roadinduced landsliding can greatly alter stream channel habitat and morphology. Unpaved roads can increase sediment production rates by more than an order of magnitude as a result of road surface erosion. The high surface erosion rate stems from the generation of surface runoff from the highly compacted road travelway, the lack of surface cover, and the availability of fine sediment due to traffic and road maintenance procedures such as grading. Sediment delivery to streams occurs primarily at road-stream crossings and secondarily by road-induced gullies. The proportion of the road network that is connected to the stream network is primarily a function of mean annual precipitation (R2=0.9), and is increased by about 40% in the absence of any engineered drainage structures. The chronic input of the fine sediment from roads can have adverse effects on freshwater aquatic ecosystems as well as coral reefs. Our present understanding of road surface erosion processes is good, but our models to predict road surface erosion and landsliding are much better for relative than absolute predictions. Climate change can greatly increase road-induced landslides and road surface erosion by increasing the magnitude of large storm events and increasing the amount of rain relative to snow. Extensive field surveys also show that relatively few road segments typically generate most of the road-related increases in sediment yields. Road surface erosion, the risk of road-induced landslides, and road sediment delivery can be greatly decreased by improved road designs and maintenance practices. Hence the greatest needs are to develop and provide land managers with the tools for identifying high-risk segments, and then to make the necessary investments in road reconstruction and restoration.

A new method to estimate species and biodiversity intactness using empirically derived reference conditions
S.E. Nielsen, E.M. Bayne, J. Schieck, J. Herbers, and S. Boutin
Critical to the conservation of biodiversity is knowledge of status and trends of species. To that end, monitoring programmes have reported on the state of biodiversity using reference conditions as comparison. Little consensus exists on how reference conditions are defined and how such information is used to index intactness. Most use protected areas or an arbitrary year as reference. This is problematic since protected areas are often spatially biased, while arbitrarily defined reference years are often not sufficiently distant in time. Biological Conservation 137 (2007)

Modelling potential effects of angling on recovery of westslope cutthroat trout (Oncorhynchus clarkii lewisi) in Alberta
Alberta’s native form of cutthroat trout, westslope cutthroat trout (Oncorhynchus clarkii lewisi), was listed in 2006 as a threatened species under the federal Species at Risk Act. Amongst other legal requirements, this action requires that an assessment of threats be conducted to determine what activities are acceptable and unacceptable with respect to the maintenance and recovery of populations of these fish. Sport angling for cutthroat trout and other species is a popular activity throughout this fish’s habitat in Alberta and has the potential to harm this species’ recovery. To investigate this potential harm, the possible effects of a variety of angling scenarios (e.g., different levels of angler effort and regulations) on stream populations of cutthroat trout were simulated using a population dynamics computer model. The results of these simulations suggested that recovery of depressed cutthroat trout populations could occur under scenarios of limited and low angler effort, and no directed harvest (i.e., catch-and-release angling). Once recovered, however, healthy populations of westslope cutthroat trout may be maintained with catch-and-release angling with moderate fishing effort. Angling regulations that allow harvest of cutthroat trout are unlikely to either maintain or recover most populations unless angler effort is controlled. Incidental mortality (either through accidental hooking mortality or illegal harvest through misidentification of trout species) in these simulations was an important factor in population maintenance and recovery. This suggests that minimizing these sources of mortality may be an important management concern for this species.

Scenario analysis in environmental impact assessment: Improving explorations of the future
Peter Duinker and Lorne Greig
Scenarios and scenario analysis have become popular approaches in organizational planning and participatory exercises in pursuit of sustainable development. However, they are little used, at least in any formal way, in environmental impact assessment (EIA). This is puzzling because EIA is a process specifically dedicated to exploring options for more-sustainable (i.e., less environmentally damaging) futures. In this paper, we review the state of the art associated with scenarios and scenario analysis, and describe two areas where scenario analysis could be particularly helpful in EIA: (a) in defining future developments for cumulative effects assessment; and (b) in considering the influence of contextual change, e.g. climate change, on impact forecasts for specific projects. We conclude by encouraging EIA practitioners to learn about the promise of scenario-based analysis and implement scenario-based methods so that EIA can become more effective in fostering sustainable development.
