“…Trail cameras have become a prominent monitoring tool that aids researchers in better understanding wildlife activity and behaviour across a wide range of habitats (Rosatte 2011;Blagdon & Johnson 2021;Surmacki & Podkowa 2022). Trail cameras can monitor animals in the wild for months, allowing researchers to make observations without the need for multiple and potentially costly field trips (Surmacki & Podkowa 2022).…”

Understanding when a species is active in its' environment is essential when designing inventory and monitoring protocols, especially for ectotherms whose activity depends on local weather conditions. The New Zealand alpine zone hosts a diverse native assemblage of invertebrates that are poorly understood yet likely to face an increasing number of threats, particularly associated with climate change and the range expansion of introduced pests. Large-bodied flightless invertebrates are particularily vulnerable to introduced predators, like mice and stoats, which have decimated native species at lower elevations. Using trail cameras, we aimed to understand what conditions and times of the summer field season (spring-autumn) are optimal for monitoring large-bodied alpine invertebrates in the Homer and Gertrude valleys, Fiordland, New Zealand, from late austral spring to late autumn (2020/2021). Beetles (Coleoptera), wētā (Orthoptera), and spiders (Araneae) were the three most common taxonomic groups detected at our sites. The activity of all three groups was significantly influenced by mean hourly temperature. Ninety-five per cent of beetle observations occurred when temperatures ranged from 5.9-12.6°C, while 95% of wētā observations occurred when temperatures were between 6.0-12.6°C. Spiders were active across a broader range of temperatures, with 95% of observations occurring when ground temperatures were between 5.4-13.0°C. The activity of all three groups was also influenced by the time of year. Beetles were observed more often in late spring, wētā in early summer, and spiders in mid-summer. The activity of spiders and beetles, but not wētā, was negatively correlated with precipitation. These results suggest optimal monitoring periods for wētā, beetles, and spiders differ. Still, if the objective is to monitor a range of invertebrates simultaneously, we recommend that surveys occur in spring and mid-summer during nights when temperatures are higher than 5.4°C with little to no rain.

“…non-invasive field surveys are commonly used to assess and monitor the presence, distribution, and/or abundance of carnivores (e.g., Patterson et al 2004;Squires et al 2004;Rosatte 2011). these surveys are often used as the basis for management decisions and actions, such as setting harvest quotas and assigning conservation status.…”

The efficacy of surveys in detecting Canada Lynx (Lynx canadensis) can vary considerably by geographic area. We conducted surveys using digital passive infrared trail video-cameras from January to April 2013, during the breeding season of the Canada Lynx, in the John Prince Research Forest in central British Columbia. We used snow-track surveys to test the efficacy of our camera surveys. We measured trail camera detection rates by survey week and location and we noted Canada Lynx activity and behaviours recorded by the cameras. The detection rate increased between January and April, reaching a peak of 8 Canada Lynx/100 camera-days in early April. Canada Lynx spent more time at camera sites displaying behaviours such as scent-marking and cheek-rubbing in late March. The combination of both snow-track and trail camera surveys was especially effective, with Canada Lynx detected at 77% of all monitored sites. Depending on survey objectives, it may be beneficial to conduct camera as well as other non-invasive survey methods for Canada Lynx during the breeding season, when survey efficacy and detection rates are maximized.
