The Roosevelt Wildlife Collection housed in Illick Hall is a vertebrate collection containing over 10,000 specimens of birds, mammals, freshwater and marine fishes, reptiles and amphibians. The collection is a result of the efforts by scientists, private collections and students since its beginning in 1919. In the collections early years it was built up from field research conducted throughout New York State. Through numerous acquisitions it now represents many genera found throughout North America.
The SUNY-ESF teaching and research greenhouse complex is located on the roof of Illick Hall. It consists of seven glass greenhouses ranging in size from 675 to 1,150 square feet. Plants grown in the greenhouses include an extensive collection of cacti and succulent plants, numerous orchids, and a wide range of relatively common through quite rare tropical plants. One greenhouse remains unheated through the winter months and houses a collection of more temperate plants that require exposure to cold temperatures during the short days of midwinter in order to bloom and resume growth as the temperature rises each spring.
