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 mapping 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 |
|
mobile geographical information system (GIS) software. |
