Abstract

Lake Ladoga, the largest lake in Europe, has about 500 islands. In the northen part of Lake Ladoga, the large islands have small lakes that gradually were isolated from Ladoga during the Holocene. In recent years, we have obtained the results of the lakes sediments studies in the Putsaari, Lunkulansaari and Valaam islands. We present the results of lithological, radiocarbon, pollen, macrofossil and diatom analyzes of islands lakes sediments sequences. The island lakes have the features associated which eliminates some of the factors influencing the development of these lakes ecosystems. And therefore island lakes are a unique archive for the reconstruction of the paleoenvironment
