Upper Thames River Conservtion Authority

In the City of London, 16 natural areas are currently designated as “Environmentally Significant Areas” or ESAs. These areas represent a variety of habitats, including upland forests, wetlands and river corridors. The ESAs are an integral part of London’s proposed Natural Heritage System connecting parks, valley lands and other open spaces. In addition to the official ESAs, London has many other natural areas within the city limits.
Seven of the 16 ESAs are publicly-owned (the others are on private lands) and are managed by the Upper Thames River Conservation Authority (UTRCA), in partnership with the City:

• Kains Woods
• Kilally Meadows
• Meadowlily Woods
• Medway Valley Heritage Forest
• Sifton Bog
• Warbler Woods
• Westminster Ponds/Pond Mills Conservation Area

 Brochures (pdf files, 8.5x14) for the ESAs are available on the Upper Thames River Conservation Authority  website or are available free of charge from:

• Tourism London Information Centre (696 Wellington Rd. South, in Westminster Ponds ESA) and the Dundas Street Information Centre (267 Dundas Street at Wellington)
• City Planning Department, 6th floor, City Hall, 519-661-250 ext. 4980
