When Eucalyptus blakelyi seedlings were placed on platforms in the canopies of mature trees, common brushtail possums, Trichosurus vulpecula , selectively browsed on seedlings that had been irrigated with a balanced nutrient solution, in preference to those that had been irrigated with tapwater. The foliage of the nutrient-irrigated seedlings contained more water, nitrogen, soluble sugar and fibre, and less tannin, starch and non-structural carbohydrates, than did that of the tapwater-irrigated plants. Its specific leaf weight was also lower. The possums browsed some foliage on tapwater-irrigated plants from the healthy seed source; this foliage contained more sugar, less tannin and less fibre than that of the less preferred plants.
