We collected foliage from 34 species of broad-leaved, deciduous trees in southern Ontario and determined an index of leaf toughness, weight per unit area, percent water, and percent of dry weight as available carbohydrate, crude fibre, hemicellulose, holocellulose, lignin, polyphenols, nitrogen, phosphorus, ash, potassium, calcium, and magnesium. We analyzed variation in these constituents within samples, among three sampling periods during one growing season, and among species.
