Telkkämäki Nature Reserve (in Finnish: Telkkämäen luonnonsuojelualue or Telkkämäen kaskiperinnetila) is a slash-and-burn heritage farm in the municipality of Kaavi in the Northern Savonia region of Finland; it covers one square kilometer (0.39 sq mi). The reserve was established in 1989 to enable visitors to see how people lived and farmed when slash-and-burn agriculture was practiced in Eastern Finland in the 15th century. Some areas of the Telkkämäki Nature Reserve are still burned annually.
