Black kauri pine (Agathis microstachya)

Family: Araucariaceae

Common names: Black kauri pine, Bull kauri, Kauri, Kauri pine, North Queensland kauri, Queensland kauri

Distributed in: Australia (Oceania and S.E. Asia)

Distribution overview: Occurs in Australia in N Queensland. Almost entirely confined to rainforests of the Atherton Tableland, at latitude 17-18￿ S and elevations of 400-900 m. The mean maximum temperature of the hottest month is 30￿C and the mean minimum of the coldest month is 10￿C (data for Atherton station). Precipitation is 1400-3300 mm, concentrated in the summer months, reaching a minimum of 25 mm in the driest month (August or September). Soils are deep loams to clays on varied silicic substrates. As with most species of Agathis, it grows as a rainforest emergent in a canopy composed of hundreds of different tree species.

Common uses: Agricultural implements, Boat building (general), Boxes and crates, Cabinetmaking, Carvings, Flooring, Food containers, Furniture, Joinery, Light construction, Matches, Mathematical instruments, Musical instruments, Plywood, Pulp/Paper products, Sporting Goods, Toys, Turnery, Vats, Veneer

Tree size: Trunk diameter is 300-350 cm

Colors: the heart isWhite, White to creamThe grain isStraight, the textureFine

Natural durability: Susceptible to insect attack, Susceptible to marine borer attack

Kiln Schedules: Kiln Drying Rate (in days) is fairly rapid

Kiln Drying Rate: Rapid (<10 days for boards < 32 mm, to <30 days for boards >= 63 mm)

Drying Defects: Internal Honeycombing Possible, Slight collapse and honeycomb

Ease of Drying: Slowly

Tree Identification: Bole/stem form is straight

Comments: General finishing qualities are rated as good

Boring: Moderately easy

Gluing: Fairly Easy to Very Easy

Nailing: Holds satisfactorily, Very Good to Excellent

Planing: Very Good to Excellent

Response to hand tools: Easy to machine

Steam bending: Moderate
