Assisted Natural Reforestation: Mapping

with Google My Maps

-Visit, sign in or create Google account, and “create new map.”
-Open your My Map on mobile device, walk project site

1. Map trees
  • with “Add Marker” (top toolbar), mark tree locations
             - name each point with tree species, height and DBH (Diameter of tree at Breast Height, or 5')
  • with “Style” (toolbar of selected point) match their icon and color scheme by species or category of interest [image 1]

2. Map areas
with “Add Line or Shape,” highlight areas of interest, such as
  • hazards (power lines, dump sites, invasive plants)
  • large areas of similar conditions (e.g. blackberry patch with scattered sweetgum/persimmon seedlings) or ecosystems (wetland, mature forest)
  • other themes depending on research objectives
Selecting an area shows its size in acres and square feet.

3. Other useful functions
  • with “Add Image,” upload photos from camera or documents
  • with “Add New Layer” (toolbar in legend), divide data points into categories to be viewed seperately [image 3]
  • with “Base Map” layer in legend, select terrain map for topography (useful for marking ridgetops, riparian or wetlands), or select basic map to conserve phone data in field.
  • Your Map can also be opened in data tables, embedded in a website, exported to a KML file, or shared by link.
