Description

Tree to 25(-38) m tall, much shorter or even shrubby on dry hillsides or in subalpine shrublands. Trunk to 1(-1.8) m in diameter, round or somewhat fluted, sometimes with a corkscrew spiral. Bark light brown weathering light gray, smooth or variously warty at first, becoming densely scaly and shedding in thick flakes, sometimes with vertical fissures. Crown conical and gracefully drooping in youth, becoming deep and narrowly to broadly dome-shaped with age, with heavy, crooked, forking, steeply to shallowly upwardly angled branches arching at the end and bearing numerous, repeatedly alternately branched, upright to drooping branchlets densely clothed with and hidden by foliage. Juvenile leaves triangular, 1.5-5 mm long, spreading from the twig at a forward angle. Adult leaves yellowish green to dark green and dotted with white stomates, 1-2 mm long, sharply or more roundly keeled, lasting 4-5 years or more. Pollen cones dull red, 3-6.5 mm long and 1-1.5 mm in diameter. Seed cones dull white with a yellowish or greenish tinge, droopy, a little fleshy, 4-8 mm long, each seed cupped for a quarter to a third of its length in a one-sided, jaggedly toothed, papery pink epimatium less than 1 mm deep. Seeds red with patches of a thin, waxy film, smooth to wrinkled (on drying), 2-2.5 mm long.

Southwestern quarter of Tasmania, Australia. Most abundant and of largest size in wet soils along streamsides and lakeshores in mixed temperate rain forests but surviving also on drier sites as a stunted tree or shrub; 0-750(-1,030) m.

 

Conservation Status

Red List Category & Criteria: Least Concern

(Lagarostrobos franklinii does not meet any criteria for a threatened category, despite massive logging which at one time reduced the population to a fraction of what it must have been prior to European settlement. While this has meant that few large trees remain, the species has shown a very good capacity to recover, much of it through resprouting and layering, and it has recovered 80-85% of its former area of occupancy and is listed as Least Concern. Nearly all (86%) of the population is in reserves and new hydroelectric projects are not envisaged)
