Column Descriptions
Listed Status: New York
| Listed Status: | (New York):Rare plants have been protected in New York State since 1933. After a long history of expanded protection efforts, the latest regulation was enacted in June 1989 and includes three rarity categories (endangered, threatened, and rare) and one non-rare protection category (exploitably vulnerable). Rare plants included on the list are protected under New York State Environmental Conservation Law section 9-1503. Part (f) of the law reads as follows: "It is a violation for any person, anywhere in the state to pick, pluck, sever, remove, damage by the application of herbicides or defoliants, or carry away, without the consent of the owner, any protected plant. Each protected plant so picked, plucked, severed, removed, damaged or carried away shall constitute a separate violation." Violators of the regulation are subject to fines of $25 per plant illegally taken. At this time, the Atlas only identifies those species listed as threatened or endangered. |

| OBL: | Obligate Wetland. Occurs almost always (estimated probability 99%) under natural conditions in wetlands. |
| FACW: | Facultative Wetland. Usually occurs in wetlands (estimated probability 67%-99%), but occasionally found in non-wetlands. |
| FAC: | Facultative. Equally likely to occur in wetlands or non-wetlands (estimated probability 34%-66%). |
| FACU: | Facultative Upland. Usually occurs in non-wetlands (estimated probability 67%-99%), but occasionally found in wetlands (estimated probability 1%-33%). |
