The number of insect species at risk of population decline and extinction is increasing rapidly. Yet we know almost nothing about the ecology of these species, except for at-risk butterflies. A growing body of literature shows how butterfly vital rates, including demography and movement, are essential for guiding conservation and recovery. History has shown us that without these data, conservation decisions often weaken, rather than enhance, population viability. This is especially true in changing landscapes. We review knowledge of vital rates across all at-risk butterflies. We have information on movement for 17 of 283 butterfly species and information on demography for 19 species. We find that habitat-specific movement behavior is key to understanding how to connect populations, and habitat-specific demography is central to managing habitats. Methods and analyses worked out for butterflies can provide a scaffold around which to build studies for the conservation of other at-risk insects.

There are many integrity gaps in the federal and provincial systems designed to protect endangered and threatened species in Canada. NGOs (Non-governmental organizations) and other stakeholders can get involved in the process of protecting species at risk, by participating in collaborative efforts through volunteerism and stewardship efforts. NGOs can also bring issues of species-at-risk protection to court through litigation. This thesis began by exploring the integrity gaps in the federal and provincial processes for species at risk protection. The thesis then examined different initiatives undertaken by NGOs to combat this issue, the first being litigation and how it can be used as a strategy to help protect species at risk, and hold government accountable. The thesis also explored the rationale behind NGO actions, as well as the possible outcomes from these court cases. Next, the thesis discussed volunteer efforts undertaken by NGOs and other stakeholders. The research was supplemented with valuable qualitative interview data from scientists, members of NGOs, members of government, and a lawyer. The thesis concluded with recommendations for further action and policy measures that can be taken to protect species at risk
