Conservation work conducted at the Canadian Conservation Institute connected with a fossil forest discovered in the Canadian Arctic Archipelago on Axel Heiberg Island, North West Territories in 1985 included analysis of fossil wood which is typically non-mineralised, substantially compressed, and contains recognisable cellulose and lignin, although the cellulose fraction is considerably reduced. Conservation treatment techniques were developed for various types of fossil from the site. The wood has been treated with a PEG freeze-drying method normally used for waterlogged wood, whereas delicate materials such as the cones and leaves have been successfully consolidated with parylene conformal coating. In order to develop a preservation strategy, work also has been conducted in surveying and in analyzing the natural erosion paths and rates at the site.
