The introduction of nonnative species is a leading cause biodiversity loss. Many invasive are cryptic or elusive in nature and therefore often evade detection, complicating their management. Occupancy modeling can reveal the presence spread over time has important management implications. Camera traps be used to estimate occupancy, proportion sites that occupied by target species. During 4-year study (2016–2020), we camera both with without lures detect Salvator merianae (Argentine Black White Tegu) at Miami-Dade County, FL. Our results from multi-season occupancy model revealed quadratic effect ordinal day was best predictor peak June, while correlated distance landscape features may facilitate tegu movement. We did not any large-scale changes course our study. also discovered use impact indicating fewer resources would required managers for effective monitoring. Understanding factors detection probabilities inform surveillance removal efforts, more efficient strategies.
