Recent Unusual Occurrences

All locations given are counties.

Natural Strays—species out of range in NJ that are represented by only one or very few observations, photographs, or specimens, dating to 2000 or later, and that probably reached NJ naturally.

* These species are also represented by pre-2000 records.

Non-natural Occurrences—species well out of range that probably arrived in NJ as intentional releases or horticultural stowaways, dating to 2000 or later.

Historic Occurrences

The Historic Occurrences list includes species reported as having occurred in New Jersey prior to 2000, but whose presence has not been confirmed since. The list below is based mainly on information in Iftner and Wright 1996 (I&W) and Gochfeld and Burger 1997 (G&B)—see Resources for full citations. All locations given are counties.

Former Residents—species for which the existence of a former population in NJ is well known to current observers or documented by numerous historical records.

Strays—species well out of range in NJ that are represented by only one or very few observations or specimens, dating to before 2000.

Former Status Uncertain—species for which too few NJ records exist to determine whether they represented a true population; species for which identification problems make interpretation of historical records extremely difficult; and species suspected to have been introduced.

Literature Record Only—species represented only by records from the literature (reviewed by I&W), with no citations or dates given.

Record Questionable—species represented by NJ specimen records, but whose occurrence in NJ seems so implausible as to suggest that the information on the specimen label is inaccurate or incomplete.
