Forest Survey 2013

You can turn the Forest Survey 2013 layer on or off using the control in the top-right corner of the map. This layer shows historical data from 2013, highlighting where four priority invasive species were found at the time: Pulu vao, Pulu mamoe, Tamaligi, and Fa’apasi. Each point on the map represents a surveyed plot, and some plots may contain more than one of these species.
