Abstract: The most cost-effective and feasible strategy for managing any recently established non-native invasive plant species (NIS) is early detection and rapid response. However, conventional sampling designs can be inefficient and costly to implement when sampling early phases of invasion. Adaptive sampling designs were specifically developed as alternatives to conventional sampling to take advantage of the rarity and clustered nature of many biological populations. One class of adaptive sample designs is adaptive web sampling, which provides a balance between increasing sampling in the immediate proximity of an already detected patch and sampling farther away from the detected patch to locate more distant satellite patches. This balance makes adaptive web sampling well suited for map-ping NIS in early invasion phases when invasive populations are rare and locally clustered. Adaptive web sampling is also more flexible than other adaptive designs because the amount of sampling effort allocated to adaptive selection can be based on local factors. This manual describes an adaptive web sampling design and a user-friendly GPS interface developed to aid implementation of the sampling design in the field. The GPS user interface is a customized application developed for ESRI’s (Redlands, CA)ArcPad® mo-bile geographical information system (GIS) software.
