Plants on Maine Islands: Interactive Map

 

This map is the culmination of decades of Maine island vascular plant data from published lists, unpublished lists, and herbarium vouchers by numerous botanists, plus all of the field work done by Glen Mittelhauser and Observatory staff over the last 30 years.  To our knowledge, this is the most comprehensive snapshot of what is known about plant distribution on Maine islands available at this time. 

Note: This map only includes species found on small islands and not species that are only found in the interior of the larger islands in the region (e.g., Mount Desert Island, Isle au Haut, Deer Isle, Swans Island, and Vinalhaven).

There is still work to be done to fill in the gaps on these data.  Our work thus far has focused on the islands from Muscongus Bay to the Canadian Border.  We hope to add data from more islands in the mid-coast and southern Maine in the future.  Please contact us if you have a plant list for a Maine Island that you think could help expand this project. 

 

How You Can Help

If you have a list of plant species from an island not already covered in this map, please contact Glen (glen@mainenaturalhistory.org).  We would love to assess it for inclusion in this project.

You can also help Maine island plants by donating any amount the the Maine Plants Fund.  Just click the donate button at the bottom of this page and selecting "Maine Plants Fund."  Thank you!
