Life History and Biology
DESCRIPTION: This leafy bulrush is in the sedge family (Cyperaceae), and is characterized by narrow leaves and a drooping flower head with chocolate-brown florets.
RANGE AND POPULATION LEVEL: Populations of northeastern bulrush are recorded from Quebec south to West Virginia. Pennsylvania has the largest number of occurrences.
HABITAT: The northeastern bulrush typically grows in palustrine emergent wetlands or vernal ponds surrounded by woodlands. These ponds typically experience a mid-summer drawdown, depending on annual precipitation quantities. This species is commonly found on mountain benches where water collects at a common drainage point.
REASONS FOR CURRENT STATUS: The decline of this species is attributed to multiple threats including; degradation of habitat from road construction and upland runoff, destruction by off road vehicles, deer browsing, shading and conversion of land for other uses.
