Endangered Plant Surveys


Running buffalo clover survey

For over 35 years, EnviroScience botanists have been performing threatened and endangered plant surveys for clients across the U.S. Although developers seldom consider searching for rare, threatened, and endangered plants on their properties, rare species surveys are frequently a requirement for obtaining development permits.

EnviroScience has trained botanists on staff who are approved to survey the federally endangered running buffalo clover (Trifolium stoloniferum), federally threatened small whorled pogonia (Isotria medeoloides), and the federally endangered Appalachian Spiraea (Spiraea virginiana).

Running Buffalo Clover Survey

Running buffalo clover is a federally endangered plant that is found in Indiana, Kentucky, Missouri, Ohio, and West Virginia, with historic records in Arkansas, Illinois, and Kansas.  The name running buffalo clover comes from its ability to spread by sending out runners, also known as stolons, similar to the strawberry plant.  EnviroScience botanists are on the U.S. Fish and Wildlife Survey’s approved list to survey running buffalo clover in Ohio and West Virginia.

Small Whorled Pogonia Survey

Small whorled pogonia is a federally threatened plant that is found within 18 eastern states and Ontario, Canada. A member of the orchid family, the small whorled pogonia is usually seen in populations of less than 20 plants and prefers acidic soils with a thick layer of dead leaves, often residing on slopes near small streams. Although listed as endangered in 1982, it was reclassified as threatened in 1994. Loss of habitat occurs due to urban expansion, some forestry practices, and occasionally recreational activities.

Appalachian Spiraea Survey

Appalachian spiraea is a federally endangered plant that is found in the Appalachian Plateaus or the southern Blue Ridge Mountains in Alabama, Ohio, West Virginia, Virginia, Tennessee, North Carolina, Kentucky, and Georgia. Appalachian spiraea is usually found in small clumps within gravel bars and creek banks of mid-size streams, ranging in size from three to ten feet. Changes in stream hydrology and invasive species most often threaten its habitat.
