Conservation of ecosystems in western North America relies fundamentally on conservation of wildlands on public land. However, these areas often contain trespass cannabis grows where threats from pesticides and other deleterious factors pose both direct and indirect threats to wildlife. Using camera traps, we monitored wildlife visitation at 5 trespass cannabis grows under a Before-After-Control-Impact (BACI) design framework (approach A), and at 89 trespass cannabis grows under a Before-After design framework (approach B), on public land across California. We aimed to quantify the visitation rates of several wildlife guilds to cannabis grows and determine whether reclamation of all infrastructure and hazards reduced visitation rates and thus risks to wildlife. Results for approach A show that overall wildlife visitation rate averaged >2x at impact relative to control locations (Fig. 2). Three of five foraging guilds preferred cannabis grows: visitation rate was 2.0x higher for herbivores (non-deer), 3.2x for omnivores (non-bear), and 4.1x for omnivores (bear). Grow reclamation did not remove preference within the study interval. In approach B, wildlife visitation dropped slightly following reclamation and peaked 1.5 yrs since grow eradication and around August. Overall, our findings support previous literature that illicit cannabis grows pose direct and indirect threats to wildlife by attracting them to contaminated areas, but also highlight an effective mitigation and restoration strategy.
