Rank Reasons
Geum peckii is a herbaceous perennial known only from less than 30 occurrences, mostly in the White Mountains of New Hampshire, but also from Brier Island and Digby Neck in Nova Scotia, in the Bay of Fundy, It is scattered but locally abundant in these restricted areas. It is threatened in the U.S. by trampling and potentially by nutrient inputs caused by overnight visitors. In Nova Scotia, the habitat has been altered by drainage ditches built for agriculture.
Range Extent Comments
Geum peckii is restricted to a small area in the White Mountains of New Hampshire (U.S.A.), Brier Island in Nova Scotia (Canada), and a small areas on the mainland of Nova Scotia.
Occurrences Comments
There are 19 presumably extant occurrences in New Hampshire within a 1,600 sq km area. As more observations between occurrences are found, they have been merged together. In New Hampshire, there is one large occurrence on Mount Washington, in the northern Presidential Range of the White Mountains. There are nine sites in Nova Scotia on Brier Island in the Bay of Fundy and Digby Neck, the neck that leads to Brier Island (Environment Canada 2010).
Threat Impact Comments
In New Hampshire, the species is sensitive to trampling by visitors. Potentially threatened by nutrient inputs near overnight huts along hiking trails and campgrounds. In Nova Scotia, the species has been experiencing a decline due to the cumulative effects of drainage ditches (built in an unsuccessful attempt to make the area suitable for farming). The ditches lowered the water table enough to attract roosting gulls to the area. Gull droppings have raised the nutrient levels in the soils and have acted as a vector for weed seeds, which are successfully colonizing the drier, more nutrient-rich sites. Nova Scotia sites are also threatened by OHV's, development for the cottage industry, fire, and potentially tourism impacts in the future.
Ecology & Habitat

Habitat

In New Hampshire, Geum peckii is found in alpine streamside ravines and moist (snowfields), rocky heath-meadow communities at 1,200-1,830 m elevation; descends to subalpine elevations (425-760 m) along high-gradient streams, especially at open cascades. In Nova Scotia, it is found near sea-level in bogs and nearby sphagnous depressions along the sea coast (Environment Canada 2010).

Reproduction

Geum peckii reproduces both sexually via wind-dispersed achenes and asexually via rhizomes (LaRue 2016; Paterson and Snyder 1999). Self-pollination is possible, though total number of seeds produced is higher when flowers are cross-pollinated (Zinck 1996). An average of 50 seeds are produced by each flower (Keddy 1986). Seeds must be cold-stratified in order to germinate and germination rates in greenhouse tests are typically low (<5% of 300 tested seeds (NEWFS pers. comm.). Other than these life-history characteristics, little is known about the population biology of this species. Factors such as survival rate, reproductive age and lifespan are not well documented.
