Abstract Early detection of an invading nonindigenous plant species (NIS) may be critical for efficient and effective management. Adaptive survey sampling methods provide unbiased best estimates distribution rare spatially clustered populations plants in the early stages invasion. However, there are few examples these being used nonnative surveys which travelling distances away from initial or source patch, a road trail, can time consuming due to topography vegetation. Nor is guidance as many adaptive would most appropriate basis invasive mapping subsequent Here we empirical complete census four invader middle invasion management area assess effectiveness efficiency three nonadaptive methods, cluster web that all originated transects. The generally sampled more NIS-occupied cells patches than standard transect approaches. Sampling along roads only was time-efficient effective, but with restricted roads. When were patchy dispersed over landscape starting at proved NIS method.
