Warning Signs Mitigate Deer–Vehicle Collisions in an Urban Area
Rob Found, Mark S. Boyce
Increasing collisions with deer (Odocoileus spp.) and other large animals, and the rise in associated public safety risks and economic costs, have made mitigation strategies a priority for both transportation and wildlife managers. Deer-crossing warning signage is one of the oldest forms of mitigating deer–vehicle collisions (DVCs), but despite their low cost and logistical simplicity, the effectiveness of standard-sized permanent warning signage at reducing DVCs has not previously been adequately determined. We used historical DVC data, based on deer carcass retrieval, to identify and target areas and periods of high collision frequency. We installed warning signs at these high collision frequency locations and then compared DVCs to un-signed control locations. The total number of DVCs at signed hotspots was significantly different in the year after the signs were installed, compared to the 3 prior years (F13 ¼ 4.99, P ¼ 0.004). Although the single year of posttreatment data means the long-term efficacy of warning signage remains unknown, we showed that in the first year after installation, deer-crossing signs targeting high collision locations can be effective at reducing DVCs.

Guidelines for Using the IUCN Red List Categories and Criteria
The Standards and Petitions Subcommittee of the IUCN Species Survival Commission
The IUCN Red List Categories and Criteria were first published in 1994 following six years of research and broad consultation (IUCN 1994). The 1994 IUCN Categories and Criteria were developed to improve objectivity and transparency in assessing the conservation status of species, and therefore to improve consistency and understanding among users. The 1994 categories and criteria were applied to a large number of species in compiling the 1996 Red List of Threatened Animals. The assessment of many species for the 1996 Red List drew attention to certain areas of difficulty, which led IUCN to initiate a review of the 1994 categories and criteria, which was undertaken during 1998 to 1999. This review was completed and the IUCN Red List Categories and Criteria (version 3.1) are now published (IUCN 2001). This document provides guidelines to the application of version 3.1 of the categories and criteria, and in so doing addresses many of the issues raised in the process of reviewing the 1994 categories and criteria. This document explains how the criteria should be applied to determine whether a taxon belongs in a category of threat, and gives examples from different taxonomic groups to illustrate the application of the criteria. These guidelines also provide detailed explanations of the definitions of the many terms used in the criteria. The guidelines should be used in conjunction with the official IUCN Red List Categories and Criteria booklet (IUCN 2001).

Catalogue of Coal Mines of the Alberta Plains
J. D. Campbell
A comprehensive catalogue is presented of all coal mines that have been registered or opened in the plains regions of Alberta. Included are data on surrounding terrain, geology and composition of the coal, and a location map on a scale of one inch to 12 miles.

Integrated Landscape Management Modelling Workshop
Policy Research Institute
Sound land-use decision-making requires that social, economic, and environmental values be balanced, and that any repercussions within these three areas due to a decision taken in another be identified and taken into account. Land-use planning and environmental impact assessments (both aspects of integrated landscape management) could be improved, and the decision-making process better informed, through the use of integrated landscape management models (ILMM).

The effects of Linear Developments on Wildlife: A Review of Selected Scientific Literature.
Jalkotzy, M. G., Ross, P. I., and Nasserden, M. D.
This report is a reference to be used when information is required regarding the effects of linear development on wildlife. It is divided into a number of sections. The basis of the literature review was an electronic search of biological and related electronic databases. The scope of this research is detailed in Section 2. Since the basis for understanding the effects of linear developments on wildlife is the ecology of landscapes, Sections 3 provides an introduction to the basic concepts of landscape ecology and Section 4 outlines the major functions of disturbance corridors. The effects of linear developments on wildlife can be divided into 6 major groupings, and these are outlined in Section 5. Section 6 examines the effects of linear corridors from the perspective of corridor type. Sections 5 and 6 are meant to be brief overviews of their respective topics. Section 7 forms the bulk of the report and examines, in detail, the effects of linear developments on different wildlife species and species groups. Large mammals are dealt with at the species level, whereas medium-sized carnivores are dealt with as a group, as are birds. The final section, Section 8, briefly reviews mitigative measures currently in use.

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.

Lake Simcoe Basin’s Natural Capital: The Value of the Watershed’s Ecosystem Services
Sara J. Wilson
This study quantifies the natural capital value of the ecosystem goods and services provided by Lake Simcoe’s watershed, a section of which is located in Ontario’s Greenbelt. At a minimum estimated worth of $975 million per year, the services provided by the watershed are worth $2,780 to each of the 350,000 permanent residents annually. This study represents the first application of this methodology to a watershed in southern Ontario. Goods and services provided by ecosystems are traditionally undervalued as they go unmeasured by conventional economics. These benefits include storage of floodwaters by wetlands, air pollution absorption, climate regulation, pollination of crops and water filtration, resulting in clean air and water and safe and abundant local food sources. In order to measure the value of these benefits, this study first describes the watershed’s natural assets – that is, the extent of the forests, wetlands, grasslands, water bodies, agricultural lands and urban or built-up areas. Then, using market-determined values (e.g. the avoided increased costs of a man-made water filtration service as a proxy for the existing capabilities of a natural system to filter water), the study was able to quantify many of the goods and services that are provided by the watershed.
