Did you know?
The number and range of this plant has been greatly reduced on Long Island as development has reduced its open upland habitat. An interesting naming problem occurred with this variety as the name Liatris scariosa var. novae-angliae (meaning New England) was being used in botany manuals without first being formally published. This was corrected in 2003 with a formal recognition of the name. The origin of the name Liatris is unknown.
|State Ranking Justification||
There are 19 existing populations but only four of these are in good condition. The rest are usually less than 100 plants each in small grassland or roadside habitats. There are approximately 30 historical occurrences but about 10 of these have been extirpated in Western Long Island and Westchester County.
The short-term trend seems stable although a few populations were extirpated by habitat alteration in recent years.
The long-term trend has been declining over the last 100 years as grassland habitats have become more fragmented by human development. There are only a few populations that remain in fairly large grasslands as others have held on in smaller grassland fragments or along roadsides. The 10 or so historical occurrences from Western Long Island, New York city and Westchester County are considered extirpated.
