Athel Pine​ Athel Pine is a tall tree growing up to 15 m tall. Older bark on the trees is dark grey or greyish brown, rough and deeply furrowed, while younger stems are smooth, jointed and have a bluish-green or greyish-green colour. Athel Pine fruits are bell shaped, 2-3 mm long and contain numerous seeds that are topped with a tuft of tiny hairs.


 * Habit: || Tree ||
 * Key Points: || * Athel Pine (//Tamarix aphylla//) is fast growing and becomes reproductive at three years of age.
 * It is able to establish on saline and alkaline soils.
 * It disperses and establishes by seed, and broken stem material is moved by flood water.
 * It is a threat to the pastoral and tourism industry and the riparian biodiversity of central Australia. ||
 * How it spreads: || Athel Pine reproduces by seeds that are dispersed by wind, flood waters and animals. The viability of seed is short, usually only a few weeks. It may also spread via suckering and the rooting of buried or submerged stem segments that have broken from the tree and been carried significant distances by flood waters (Navie 2004). ||
 * Where it grows: || Athel Pine grows in semi-arid, arid, sub-tropical and warmer temperate regions and is particularly common along inland waterways, as well as near towns, communities, homesteads, stockyards and bores. It is also a weed of open woodlands, grasslands, pastures and roadsides (Navie 2004). It is tolerant of saline and alkaline soils (CRC 2003). ||
 * Flower colour: || White, Pink ||
