NatureServe Status

Global Status: G5
Global Status Last Reviewed: 29Jul2015
Global Status Last Changed: 16Jun1988
Ranking Methodology Used: Ranked by inspection
Rounded Global Status: G5 - Secure
Reasons: Potamogeton vaginatus occurs across a broad range that includes Eurasia as well as North America. It is somewhat less common than previously thought because all supposed populations of this species in the northeastern U.S. have been determined to be P. filiformis. P. vaginatus is very common in Saskatchewan, the Yukon, and the Northwest Territories.

NatureServe Global Conservation Status Factors

Range Extent Comments: Potamogeton vaginatus occurs primarily in northwestern North America and in Eurasia. In North America, it ranges from Quebec and Ontario west to British Columbia and north to Alaska; and from Canada south to Oregon, Utah, Colorado, and South Dakota.

Number of Occurrences: 81 to >300
Number of Occurrences Comments: Collected at close to 100 sites in North America. This species also occurs in Eurasia.

Population Size Comments: Very frequent and abundant in Saskatchewan, the Yukon, and the Northwest Territories (Harms pers. comm. 1995, Cody pers. comm. 1995). Can occur in large masses in appropriate habitat.

Overall Threat Impact Comments: P. vaginatus is threatened by water pollution by mining and agriculture, eutrophication of ponds and lakes, lakeside development, invasion of habitat by exotic plant species, and changes in hydrology.

Short-term Trend: Decline of <30% to relatively stable

Intrinsic Vulnerability Comments: Sensitive to changes in water quality.
