Astronium is a common tree with an area of natural distribution, from Mexico and the Caribbean through Central America and South America, to the Andes Mountains in the west and south to Argentina. There are no US CITES regulations (reciprocal international ecoregion treaties concerning threatened or endangered species) with references to Astronium.
It is found at altitudes ranging from 500 to 3,000 feet, but is most common at 1,500 to 1,800 feet in both dry and humid forests. It does not tolerate saturated or heavy clay soils but grows well in poorly drained limestone or rocky and alluvial soils. Best growth is obtained on lighter soils with less than 40% clay, neutral pH and good drainage. In most of its range it is considered one of the major canopy species in both primary and secondary forests. It is a sub canopy species in marginal lowlands or very high elevations. It is considered a good candidate for plantation farming with easy germination, wide habitat range and 35 to 45 year merchantable harvest rotations.
Astronium is a deciduous tree maturing to a maximum of 25 to 105 feet tall and 1 to 3 feet in diameter depending on habitat and growing conditions. It is a relatively fast growing tree averaging 2-5 growth rings per inch to maturity with 2 to 4 inches of white sapwood. The tree is symmetrical with a straight bole, small narrow buttress flanges 3 to 6 feet tall, and a spreading or round dense crown.
Color when fresh is light orange to reddish brown and is more or less conspicuously marked with vertical blackish bands of variable spacing. There is often a variegated grain appearance, which produces a very striking and beautiful mottled figure. Continuous unprotected exposure to sunlight turns the color more reddish and accentuates the black striping but eventually turns it a uniform silver-grey. The grain varies from straight to intercrossed; the texture is fine and homogenous; and the luster generally high. Wood cells are relatively square, small and medium to very thick-walled. There are few to minor mineral inclusions with silica generally absent. The wood is very heavy, with a basic specific gravity of .75 to .79. The green weight is 5,500 to 5,700 lbs per thousand board feet and 3,400 to 3,550 lbs per thousand board feet at 12% moisture content. Tiger Deck products are dried to 7-9% moisture content and weigh 2,750 lbs per thousand board feet on a nominal basis.
