Number Of Individuals

The sparsely documented lycophyte, Howell’s Quillwort (Isoetes howellii), occurs in Canada in four distinct areas of British Columbia in a variety of microhabitats. Before 2010, two areas of occurrence were known in Canada. Two additional clusters of occurrences have been discovered in the last decade. In Canada, I. howellii is found in open, ephemeral wet swales, shallow ponds, and periodically flooded shorelines, channels, and back beach meadows. Habitat rarity may be the primary reason for the large gaps between areas of occurrence. The current viability of the Canadian population is dependent on maintaining the recently discovered large number of individuals in the North Thompson River Region. Isoetes howellii shares many similarities with fellow diploid, Bolander’s Quillwort (Isoetes bolanderi). The possibility that it represents a low-elevation subspecies of I. bolanderi requires further investigation. Isoetes howellii is rare in British Columbia and warrants consideration as a species at risk in Canada.

Species Groups

Patterns in the geographic distribution of seven species groups were used to identify important areas for conservation in British Columbia, Canada. Potential priority sites for conservation were determined using an integer programming algorithm that maximized the number of species represented in the minimum number of sites. Sweep analyses were used to determine how well the set of priority sites identified for each species group represented the other species groups. Although areas of highest species richness were different for each species group, they all included sites in the southern interior of British Columbia, where there is limited protection. Furthermore, less than 13% of the distribution ranges for 23 of 25 bird species of special conservation concern were located within existing protected areas. Species at risk of extinction were poorly represented (26%–42%) in priority sets of sites selected for amphibians, reptiles, birds, and mammals, since these sites were generally scattered throughout the province. However, priority sites for species at risk represented 72%–91% of the species in other groups. Therefore, conservation activities in sites identified for such species have the potential to benefit many other species. These sites could be investigated in more detail to augment existing conservation and protection efforts in British Columbia.

Species Declines

British Columbia has the greatest biological diversity of any province or territory in Canada. Yet increasing numbers of species in British Columbia are threatened with extinction. The current patchwork of provincial laws and regulations has not effectively prevented species declines. Recently, the Provincial Government has committed to enacting an endangered species law. Drawing upon our scientific and legal expertise, we offer recommendations for key features of endangered species legislation that build upon strengths and avoid weaknesses observed elsewhere. We recommend striking an independent Oversight Committee to provide recommendations about listing species, organize Recovery Teams, and monitor the efficacy of actions taken. Recovery Teams would evaluate and prioritize potential actions for individual species or groups of species that face common threats or live in a common area, based on best available evidence (including natural and social science and Indigenous Knowledge). Our recommendations focus on implementing an adaptive approach, with ongoing and transparent monitoring and reporting, to reduce delays between determining when a species is at risk and taking effective actions to save it. We urge lawmakers to include this strong evidentiary basis for species recovery as they tackle the scientific and socioeconomic challenges of building an effective species at risk Act.

The purpose of this thesis is to evaluate the effectiveness of current legal measures for protecting species at risk in Canada through an interpretive qualitative method. Four species case studies were analyzed: The Eastern Loggerhead Shrike, Jefferson Salamander, Northern Spotted Owl, and Vancouver Island Marmot. Policy recommendations for reforms arising from the research are: i) inter-jurisdictional cooperation is imperative for protecting species at risk; ii) dedicated species at risk legislation is crucial, and it is recommended that such legislation exist at both federal and provincial levels; iii) flexibility instruments and exemptions to existing law should be scientifically informed and used cautiously; iv) private landowners are significant stakeholders and stewardship efforts are important; v) scientific information and the definition of critical habitat for species at risk are crucial. The thesis concludes that a science-based precautionary approach to species protection is fundamental to address the plight of species at risk in Canada.
