South Okanagan Similkameen Bighorn Sheep Project
The emergence of psoroptic mange in British Columbia is a significant conservation concern for wild sheep. Limited opportunity for direct intervention in Psoroptes disease outbreaks has focused regional, provincial, and international attention on this management challenge. Current work is focused on assessing: the risk of Psoroptes transmission among South Okanagan Similkameen (SOKS) bighorn sheep herds; the prevalence of disease within and among herds; annual lamb recruitment; and adult mortality. These data will help to evaluate the influence of psoroptic mange on Similkameen bighorns and inform development of management actions for declining herds.

Seabird Bycatch in Commercial Salmon Fisheries
Seabird entanglement in commercial fishing nets can be significant conservation issues. The Canadian Wildlife Service conducted an observational study of seabird counts and behaviour (flying versus floating) around commercial fishing vessels to identify factors that may correspond to increased risk of seabird entanglement in fishing nets. Our analysis investigated potential indicators of net entanglement risk for rhinoceros auklets (Cerorhinca monocerata), the most abundant seabird detected during at-

Wild Sheep Horn Growth and Harvest Regulations
In North America, most wild sheep harvest regulations restrict legal harvest to males with a specified minimum horn curl. Because reproductive success is skewed toward larger males that are socially dominant, harvest regulations that target large males may select against high-

Trial Tributary Enhancements: Site Selection and Design Recommendations
Normal reservoir operations have the potential to effectively disconnect tributaries from the reservoir and limit fish migration during the low water drawdown period, when streamflow into the reservoir may become shallow and braided across the exposed reservoir floodplain or large woody debris accumulates. This project builds on previous recommendations to develop an experimental mitigation trial using proven techniques to improve fish access to affected tributary systems. Mitigation trials were implemented by BC Hydro at two of the selected sites in spring 2014.
