The Hampton Furnace grass that changed the question

Documented history and research · Sources compared

A plant missed in earlier searches appeared in 2004. Later, a federal taxonomic decision changed the grounds for considering it for protection.

Found after earlier searches failed

A federal assessment records unsuccessful searches at Hampton Furnace Pond in the 1950s and in 2002. In July 2004 Russell Juelg discovered a population identified by Ted Gordon as Hirst Brothers’ panicgrass. The assessment counted at least twenty-eight fruiting culms: flowering stems, which should not automatically be translated into the same number of separate plants. USFWS candidate assessment (2013).

The discovery followed a peat-burning fire in 1999 and flooding in 2002. The 2015 assessment raised fire as a possible influence but said there was no direct evidence establishing its ecological role. The sequence is suggestive; it does not prove that fire caused germination or that the plant had only recently arrived. USFWS candidate assessment (2015).

A different reason for a federal decision

In 2016 the U.S. Fish and Wildlife Service removed Dichanthelium hirstii from its candidate list. Its stated reason was taxonomic: the Service accepted a treatment placing the plant within a more widespread taxon. It acknowledged having previously overlooked the significance of that synonymy. The finding was therefore not an announcement that the small pond populations had recovered. USFWS finding, October 6, 2016.

The distinction preserves two separate stories. Field observers documented a rare-looking plant after repeated failed searches; federal reviewers later changed how they interpreted its classification under the Endangered Species Act. Neither decision erases the observations at Hampton Furnace. Nor does the federal finding alone resolve every botanist’s treatment of the plant’s identity. USFWS finding, October 6, 2016.

Sources and research limits

This describes the 2016 federal finding, not a claim of universal taxonomic agreement or present state-list status. The 2013 assessment correctly places Hampton Furnace Pond in Burlington County; an older assessment’s Atlantic County label is not adopted.
