The leaves are variable, being 15–25 mm (5 ⁄ 8 –1 in) long and flat on young trees and shaded lower branches in older trees. The leaves are scalelike, 5–10 mm ( 1 ⁄ 4 – 3 ⁄ 8 in) long on shoots in full sun in the upper crown of older trees, with a full range of transition between the two extremes.

[ 3 ] After the first rains following a fire, the landscape is dominated by small flowering herbaceous plants, known as fire followers, which die back with the summer dry period.
Red maple is a medium quality firewood, [30] possessing less heat energy, nominally 5.4 gigajoules per cubic metre (18.7 million British thermal units per cord) , than other hardwoods such as ash: 7.0 GJ/m 3 (24 million British thermal units per cord), oak: 7.0 GJ/m 3 (24 million British thermal units per cord), or birch: 6.1 GJ/m 3 (21 million ...
