plant species in undocumented places, 2006-2009

February 27, 2010

Proving the existence of a terrestrial plant species in an area is usually easier than proving the existence of a terrestrial animal species.  The mammal, bird, reptile or amphibian will sometimes flee if approached, or might spend 95% of its lifetime (or 99.9% of its lifetime during daytime) down a hole in the ground.  The plants are out there sitting in plain view and do not hide–although some annuals essentially disappear part of the year, and even some perennials cannot be assigned with certainty to a particular species unless their flower or seed can be examined.

There are still plenty of cases in which the occurrence of a plant species in a particular mountain range or valley area has simply not yet been documented “according to science.”  When I compare the current Utah State University digital database of Utah’s plants with my own observations, I can come up with a list plant species’ occurrences that that online database does not include.  I’m posting this list here partly to demonstrate how our current, formal assessment of the ranges of Utah’s native plant species is somewhat incomplete.

Here is my current list of 25 undocumented plant localities I have noticed:
