Into tracking weeds? Check out The Nature Conservancy's WIMS, short for "Weed Information Management System." This free software can be used on a desktop, laptop, or even palmtop computer systems. WIMS gives you the ability to record or import mapping data, to produce reports, and to assess infestations and record treatment types using the included templates. Visit the site to download the software and find out what you need to get started doing your own invasive species tracking.
