Taavinsaari conservation area is located in Rautalampi near Southern Konnevesi National Park, and it was purchased from a private owner. The aspen-dominated forest is a dry grove, with highly versatile natural assets. In addition to aspen, birch, and coniferous trees, Taavinsaari also boasts some demanding grove species, such as little-leaf linden, mezereum, and honeysuckle.

It is possible that domestic animals were brought to the island for summer pasture before the wars. In this part of Finland people used to take their horses, cows and sheep to the islands for the summer; horses were still kept on nearby Kumpusaari Island in the 1960s. The presence of germander speedwell, meadow vetchling, and bush vetch suggests the island was used for pasture and this influenced its flora.

The conservation area, measuring just over four hectares, also includes a beautiful, unusual coastal bog. The island is also home to grey-faced woodpeckers, great spotted woodpeckers, and black grouse.
