Optimizing camera traps for monitoring small mammals. PLoS ONE. 8(6):e67940. doi:10.1371/ journal. pone.0067940. Optimal specifcations for a low-cost camera trap for small mammals. Te factors tested were 1.) trigger speed, 2.) passive infrared vs. microwave sensor, 3.) white vs. infrared fash, and 4.) still photographs vs. video. A new approach was tested to standardize each camera’s feld of view success rates were compared of four camera trap designs in detecting and taking recognizable photographs. 7.3 Species Monitoring Some populations are naturally dynamic because of life history strategies ( r - versus k -reproductive strategies) while others may fuctuate on a generational, seasonal, or peri- odic basis depending on various environmental or biodiversity factors. Multiple investi- gation strategies may be needed to understand the dynamics of a species’ population size. Surveys, monitoring, and research to facilitate appropriate conservation actions must be conducted to determine vulnerability of priority species to specifc threats and studies should provide recommendations for mitigation and restoration. In North Carolina, birds and sea turtles are the only vertebrate groups for which there are historically established, standardized, long-term monitoring eforts. Recent eforts have incorporated national pro- tocols for acoustic bat monitoring at a regional landscape level. It is important to continue implementing established monitoring programs to further strengthen trend and popula- tion estimates, and, as baseline inventory and survey data allow, to establish new monitor- ing eforts across all other taxa groups. In addition to the work conducted by NCWRC, the Commission coordinates a great deal of species status and population monitoring conducted by others and manages a collection permit system to regulate the collection of nongame fauna. Te data from annual collection permit reports submitted by permit holders is reviewed by NCWRC and added to a state- wide database. Voucher specimens collected during priority aquatic species surveys and monitoring eforts are archived at the NC Museum of Natural Sciences (NCMNS) to iden- tify and document where species occur; this information is included in datasets managed by the Museum. All of the data collected by NCWRC becomes part of a database managed by the North Carolina Natural Heritage Program (NCNHP) and available for public use through the NC Natural Heritage Data Explorer (https://ncnhde.natureserve.org).
