Svjatoj Peninsula expedition
This expedition was the first international biological expedition to Siberia with special respect to wetlands. 145 species of birds were observed during the course of the expedition, of which 40 were new to the region. The most important observations were of Hooded Crane, Asiatic Dowitcher, Pallas and White Fish Eagles. They also performed the first systematic botanical, herpetological, ichthyological and mammalogical research in the wetlands of this penninsula. Although the conservation of the local species could benefit from this work, for economical reasons not all the recommended work could be practically done. However on the basis of the expedition they founded an International Centre for research and conservation of Siberia and have been continuing to conduct field work there.
