Book Description
The Interprovincial Forest Fertilization Program comprises 81 standardized experiments established by the provincial forest services of New Brunswick, Quebec, Ontario, Manitoba, and Alberta, and by the Canadian Forestry Service in the provinces of Nova Scotia and Saskatchewan. Seventy-three experiments were remeasured after 10 growing seasons. The field trials were designed to test the effect of nitrogen when applied as urea at the rates of 112 and 224 kg/ha, and the effects of combined nitrogen, phosphorus, and/or potassium additions on the growth of pole-size and semimature conifer stands. In the combination treatments, nitrogen was applied at the high rate, phosphorus as triple super phosphate at the rate of 112 kg/ha, and potassium as potassium chloride, also at the rate of 112 kg/ha. This final report contains the 10-year response data, with sections of the 5-year report included to present a more complete picture.

Book Description
Many species of fish occupying inland waters reside in watershedsthat were or still are surrounded by forests and are dependent inmajor ways upon such cover. The interactions between fishes andforests are complex, multifaceted, dynamic processes involving mostinland surface waters, forests, subsurface waters, geology andsoils, climate and its changes, and the biotic components of therelevant ecosystems. These interactions also include the aspects offorestry tied to human development, economics, population growthand even philosophies. Fishes and Forestry is truly a landmark publication. Theeditors, Professors Northcote and Hartman, have drawn together andcarefully edited chapters written by 56 scientists from around theworld, covering a vast wealth of information never before appearingwithin the covers of one book. Following an introductory chapter,this exceptional work is broadly divided into sections covering:the ecology of forests, streams, lakes and estuaries; fish biologyand ecology; forestry activities and their effects on aquaticsystems and fishes; 14 chapters covering examples of fish-forestryinteractions from around the world and a final section coveringmeans of effecting better fish-forestry interactions. Fishes and Forestry is an essential purchase for allthose involved in inland fisheries, forestry and their interaction,including fisheries scientists, fish biologists, ecologists,environmental scientists and forestry scientists. Libraries in alluniversities and research establishments where these subjects arestudied and taught should have several copies on their shelves.

Book Description
Reviews literature on fertilization of jack pine forest, with reference to Ontario conditions. Topics covered include nutrient distribution in jack pine stands, factors affecting jack pine growth response to fertilization (soil properties, stand characteristics, type of fertilizer, method and timing of application, stand management), and results of field trials examining jack pine response to fertilization and thinning.

Book Description
"This report examines how forest management can affect the carbon (C) balance of Ontario's forests. Ten forest management activities organized in four themes were examined: stand establishment (site preparation, planting, and vegetation management), growth enhancement (thinning, fertilization, and genetic improvement), forest protection (from forest fires, and insect and disease infestations), and harvesting (controlling the area occupied by roads, skid trails and landings, and reducing the area disturbed by harvesting)."--Document.
