  • Amherst Island – Biodiversity Threatened
    Amherst Island – Biodiversity Threatened Algonquin Power plans to build 31 to 37 (500 foot tall) Industrial Wind Turbines on Amherst Island. If these are erected, the adverse consequences to Amherst Island’s unique environment will be significant, perhaps irreversible. The project must be stopped! Amherst Island: § 32 Species at Risk § Located on the Atlantic Migratory Flyway § Important Bird Area (IBA) of Global Significance § Internationally recognized for concentrations of wintering hawks and owls / Owl Woods nd § Ranked 2 in biodiversity significance (Lake Ontario Islands - Northeast) For Additional Information go to: ProtectAmherst.yolasite.com 1 Why Algonquin Power cannot be allowed to build 31 to 37 industrial wind turbines on Amherst Island: Amherst Island is an Important Bird Area (IBA) of Global and Continental Significance § The Amherst Island IBA, which encompasses the entire island, is recognized as being a site of Global and Continental Significance for Congregatory Species. Sizeable spring congregations of Brant and Dunlin have been recorded. Between 1994 and 1997 the average number of Brant staging at this site during the spring migration was 3,550, representing just over 1% of the North American population. 1 A diversity of habitats has resulted in Amherst Island becoming a renowned site for a wide variety of other birds including shorebirds, raptors, and land-birds such as large concentrations of migrating swallows. Amherst Island is located on the Atlantic Migratory Flyway § Amherst Island, located on the Atlantic migratory flyway in Lake Ontario, is seasonally impaired by fog and other weather events. Migratory birds and those that inhabit the island often experience low visibility conditions, this may increase the potential number of turbine blade/bird collisions.

  • Amherst Island Guide
    Amherst Island is one of the best known spots in Ontario for wintering birding because the island regularly supports large populations of hawks, harriers, owls, shrikes and waterfowl. In spring and autumn Amherst Island can be a great place to see migrating waterfowl, shorebirds and passerines. During the summer months the island is home to a few notable breeding species like Wilson's Phalarope. Virtually all of the land on Amherst Island is privately owned, so most birding is done from the roadside. There are a few properties however, to which land owners kindly allow public access. Below is a list of some of the best birding spots on the island. Directions: To get to Amherst Island, drive about 20 km west of Kingston on Bath Road (aka Loyalist Parkway or Highway 33) to the town of Millhaven. Follow the signs to the Amherst Island ferry dock. At the time of this printing the ferry runs between 6:00 a.m. to 2:00 a.m. daily. It departs Millhaven on the half-hour and the island on the hour. At present there is a $9.00 fee for a round-trip crossing per vehicle. An up to date sailing times can be found on the Ministry of Transportation website (http://www.mto.gov.on.ca/english/traveller/ferry). A. Front Road Front Road runs the length of the island but it is the eastern end of the road between Stella (where the ferry docks) and Lower 40 Foot Road that is most heavily birded. Water views of Stella Bay, Preston Cove and the North Channel can provide views of good numbers of water birds throughout migration and winter.

  • Short-Eared Owl (Asio Flammeus) Population Monitoring in Southern and Eastern Ontario Summer 2003
    Short-eared Owl (Asio flammeus) Population Monitoring in Southern and Eastern Ontario Summer 2003 Leslie M. Hunt Project Director The Migration Research Foundation and Marcel A. Gahbauer Research Director The Migration Research Foundation November 2004 Short-eared Owl (Asio flammeus) Population Monitoring in Southern and Eastern Ontario Summer 2003 ABSTRACT The North American Short-eared Owl (Asio flammeus) population has been steadily declining since the mid 1960s. In southern Ontario, the Short-eared Owl was once the most frequently encountered owl, but has become very scarce and localized. It has recently been recommended for Special Concern status in Ontario. Little is known about the species’ breeding sites or movements, and there is debate as to whether the species deserves a higher conservation status. In order to accurately evaluate population status and effectively guide recovery efforts, The Migration Research Foundation (MRF) conducted a survey of the breeding population in southern and eastern Ontario. MRF, with the help of landowners and volunteers from the birding community, located and monitored nest sites, mapped nesting habitat, and set traps for the purpose of banding and blood-sampling adult owls. Approximately 40 historical or suitable nest sites were monitored, with evidence of Short-eared Owls being present found at only five. No owls were successfully trapped. 2 TABLE OF CONTENTS 1.

  • AMHERST ISLAND July 2014
    association to protect PO Box 6, 5695 Front Road, Stella, ON K0H2S0. AMHERST ISLAND July 2014 Engineering and Economic Risk Analysis of the Algonquin Power Company Amherst Island Wind Energy Generating System1, 2 EXECUTIVE SUMMARY An engineering and economic analysis of the Amherst Island wind energy project is presented. Algonquin Power announced that the 75 MW project will generate 247 GWh per annum. This we dispute. The sound pressure level assessment of turbine noise at island homes, written by a consulting company for Algonquin Power, asserts that the project will comply with the Ontario wind turbine noise regulations. This also we dispute. Other significant risk factors include: cost over-run associated with building on an island; the likelihood that the current rate regime will be maintained over the 20- year contract period; the omission of decommissioning costs from the project cost; mitigation measures to protect the natural and cultural heritage of the island; mitigation measures required to obtain “net benefit permits” for species at risk from the Ministry of Natural Resources; potential law-suits aimed at turbine hosts for devaluation of neighbouring property; the lack of a road-use agreement and an emergency response plan; resistance to the present ill-conceived and ill- prepared project by the community, Loyalist Township and the County of Lennox and Addington; IESO control of grid access. The annual energy generation analysis in this report is based upon the seven- year performance of the province-wide system of wind energy generating systems and the relative wind resource from the provincial wind atlas. The most probable energy generation by the 75 MW Amherst Island project is an initial 170 GWh per annum, about two-thirds of Algonquin’s projection.
