Status: Threatened, listed April 22, 1992

 

Habitat: Cool, wet groundwater-fed limestone cliffs

 

Lead Region: 3

 

Region 3 Lead Office: Twin Cities Field Office

 

Range: Cliffs in driftless area of southeastern Minnesota and on a lakeshore in New York.

 

 

Leedy's roseroot is listed as threatened under the Endangered Species Act. It grows in only four populations in Minnesota and two in New York.

 

Species whose populations are so widely separated from each other geographically are known as "disjunct" species. The Leedy's roseroot pattern of distribution suggests that it is a glacial relict - a plant that was more widespread at the end of the last glaciation but which has since become isolated because of the loss of appropriate habitat in intervening areas as the climate has warmed.

 

The New York populations occur on cliffs along the western shore of a lake. In Minnesota, this species is found on shallow ledges on north-facing dolomite cliffs about 100 feet high. Plants only groww in crevices in maderate cliffs, a very specialized habitat where groundwater seeps through the rock and is cooled by air coming from underground air passages in karst topography. This results in a constantly wet, dripping condition, an unusual product of a long geological history.

 

Leedy's roseroot is a perennial member of the stonecrop (orpine) family. Plants in this family, which includes the common jade plant, have waxy leaves that enable them to tolerate periods of water stress.

 

This plant was discovered by John Leedy in 1936 on a cliff along the North Branch Root River near Simpson, Minnesota in Olmsted County. Before then, it was unknown to science.
