1 Japanese Stiltgrass, a shade-tolerant invasive annual grass of forests, wetlands, damp fields, lawns, trails and roadside ditches has been identified in Short Hills Provincial Park

Please refer to the Canadian Food Inspection Agency (CFIA) website and park kiosks for additional information and pictures.

Why it’s a problem
Japanese stiltgrass can form dense stands that outcompete native vegetation. It reduces the regeneration of native woody species and the overall biodiversity of the invaded ecosystem.

What it looks like
Japanese stiltgrass is a sprawling grass. Stems are 40-120 cm long and 1-1.5 mm thick. The lower portion of the plant is prostrate while the upper portions and flowering branches are erect. It roots at its stem nodes. Leaf blades are pale green, narrowly elliptic, 4–9 cm long and 5–15 mm wide, with a characteristic shiny midrib. Leaf sheaths are shorter than internodes. Inflorescences are terminal racemes, 3-9 cm in length.

Where it’s found
Native to Asia, this species has naturalized in the eastern U.S. and continues to spread in the northeast. One small population of Japanese stiltgrass has been confirmed and is under official control in southern Ontario.

How it spreads
Fruits and seeds are dispersed by water and can attach to clothing or animal fur. Bird seed, soil, nursery stock, hay, muddy tires, equipment, vehicles, and footwear are additional means of dispersal. Seeds can persist in the soil for as long as five years.

Japanese stiltgrass is regulated as a pest in Canada under the Plant Protection Act. The species is prohibited and therefore importation and domestic movement of regulated plants and their propagative parts is not permitted. If found, regulatory action can be taken.

Similar species
Japanese stiltgrass is similar to the North American native white cutgrass (Leersia virginica). However, distinctive traits of Japanese stiltgrass include hairless nodes, smaller leaf blades, purple fall colouration, and a shinier blade midrib. Moreover, Japanese stiltgrass is an annual weed with fibrous roots and a spike-like inflorescence, whereas Leersia species have rhizomes and a panicle type of inflorescence. Japanese stiltgrass may also be mistaken for another North American native, deertongue panicgrass (Dichanthelium clandestinum), as well as for small carpetgrass (Arthraxon hispidus).

What to do about it
Please contact your local CFIA office if you think you have found Japanese stiltgrass or other regulated invasive plants. The CFIA will follow-up to determine if further action is needed.

*Invasive plants are plant species that can be harmful when introduced into new areas. These species can invade agricultural and natural areas, causing serious damage to Canada's economy and environment.

2 A portion of Swayze Falls trail is no longer passable and will be temporarily closed due to a failed bridge. The area is in the South West corner of the park near the Swayze Falls trail head at the Roland road parking lot . Please adjust your plans on the day of your visit. The closure will remain in place until the repairs can be made.
3 Short Hills Provincial Park will be closed to the public to honour treaty rights with a First Nation Deer Harvest.

The Haudenosaunee Confederacy has notified the Ministry of the Environment, Conservation and Parks that it wishes to exercise its right to harvest deer in Short Hills Provincial Park. The park will be closed on the following dates and will re-open at 8 a.m. the following morning:

• Wednesday, October 12
• Tuesday, October 25
• Saturday, November 5
• Wednesday, November 23
• Saturday, December 3
• Wednesday, December 14

Ontario recognizes the rights of this local First Nation to conduct a deer harvest in the park. The ministry also recognizes and seeks to balance the interests of the different users of the park and local community. Working with the ministry, the Haudenosaunee Confederacy has agreed to only carry out its harvest during outlined times and within the park boundary.

Public safety is the primary concern of the ministry. This is why the park will be closed to the general public for the duration of the deer harvest. Access points will be monitored. Park closures are authorized under the Provincial Parks and Conservation Reserves Act, 2006. For safety reasons, on the harvest dates do not enter the park and please comply with all posted notices.

To help protect the safety of the public, the harvesters and ministry staff, a number of measures will be put in place:
• Archery will be the means of harvesting deer. No guns will be allowed.
• A harvest zone has been established and the deer harvest will stay confined to the agreed-upon zone.
• Harvesters will be stationary and away from the park boundary.
• All participants will be advised of the safety protocols and procedures.

Ministry of the Environment, Conservation and Parks

• Ministry staff will be present at authorized access points and other locations to advise members of the public and park users that the park is closed during the harvests and that access is prohibited.
• Notices will be posted at the park entrances.
• Each harvest will consist of a harvest day (beginning one half-hour before sunrise and end one half-hour after sunset) and post-harvest maintenance the next morning (beginning at sunrise and ending at 8:00am.

All First Nation harvesters will be made aware of the terms of the harvest agreement that has been reached between the ministry and the Haudenosaunee Confederacy to ensure a safe and humane deer harvest.
