Description

False Hop Sedge is a grass-like perennial plant that grows 50 to 130 centimetres tall, typically forming dense clumps of several stems. It has a triangular stem and four to seven leaves about 30 to 80 centimetres long.

Flowers grow in three to eight spikelets near the top of each stem, which are typically light green but become light brown as they age.

Action we are taking:

Range

False Hop Sedge ranges from Florida and Texas north to Quebec and Ontario. In Ontario, seven occurrences are known to persist. In Quebec, there are three persisting populations and three populations that are being restored where False Hop Sedge is believed to have been extirpated. The largest populations occur in southern Ontario.

Habitat

In Canada, this plant most often grows in riverine swamps and marshes, and around temporary forest ponds. It prefers open areas and areas under forest canopy openings, with lots of sunlight.

Threats

The main threat to this plant is habitat loss and degradation, especially conditions that reduce the amount of sunlight reaching the plant. Competition from invasive plants such as Reed Canary Grass (Phalaris arundinacea) and Tall Manna Grass (Glyceria maxima) is an increasing threat. Changes to the quantity and quality of ground and surface water due to the operation of dams, development and agricultural activities may also threaten False Hop Sedge.

Protection

False Hop Sedge is protected under Ontario’s Endangered Species Act and the federal Species at Risk Act.

What You Can Do to Help the False Hop Sedge

  • The Ministry of Natural Resources tracks species at risk such as the False Hop Sedge. You can use a handy online form to report your sightings to the Natural Heritage Information Centre. Photographs with specific locations or mapping coordinates are always helpful. nhic.mnr.gov.on.ca
  • Report any illegal activity related to plants and wildlife to 1-877-TIPS-MNR (847-7667).
  • Private land owners have a very important role to play in species recovery. If you find False Hop Sedge on your property, you may be eligible for stewardship programs that support the protection and recovery of species at risk and their habitats.
  • Volunteer with your local nature club or provincial park to participate in surveys or stewardship work focused on species at risk.
  • Invasive species seriously threaten many of Ontario’s species at risk. To learn what you can do to help reduce the threat of invasive species, visit: ontario.ca/invasivespecies; www.invadingspecies.com; www.ontarioinvasiveplants.ca; and, www.invasivespecies.gc.ca.
  • The Canada-Ontario Farm Stewardship Program is available to farmers registered under the Canada-Ontario Environmental Farm Plan to encourage greater protection and conservation of habitat for species at risk. Find more information at www.omafra.gov.on.ca/english/environment/efp/efp.htm.

Did you know?

The tiny flowers of False Hop Sedge are wind pollinated, so the plant does not attract many insects. However, the caterpillars of various butterflies, skippers, and moths feed on various sedge species, while a number of species of birds feed on the seeds.

Did you know?

The plant’s spikelets are quite large and have been compared in appearance to spiked clubs and similar weapons used in medieval battles.

Did you know?

As the name suggests, False Hop Sedge closely resembles Hop Sedge (Carex lupulina). The only reliable way to distinguish them is by closely examining the fruit, which has distinctive knobs on the two outer edges in False Hop Sedge.

Did you know?

It is believed that this plant’s seeds are dispersed by water.
