The Noble Fir (Abies procera) is a western North American fir, native to the Cascade Rangeand Coast Range mountains of extreme northwest California and western Oregon andWashington in the United States.
t is a large evergreen tree typically up to 40–70 m (130–230 ft.) tall and 2 m (6.5 ft.) trunk diameter, rarely to 90 m (295 ft.) tall and 2.7 m (8.9 ft.) diameter, with a narrow conic crown. The bark on young trees is smooth, grey, and with resin blisters, becoming red-brown, rough and fissured on old trees. The leaves are needle-like, 1-3.5 cm long, glaucous blue-green above and below with strongstomatal bands, and a blunt to notched tip. They are arranged spirally on the shoot, but twisted slightly s-shaped to be upcurved above the shoot. The conesare erect, 11–22 cm long, with the purple scales almost completely hidden by the long exserted yellow-green bract scales; ripening brown and disintegrating to release the winged seeds in fall.
It is a high altitude tree, typically occurring at 300-1,500 m altitude, only rarely reaching tree
It is very closely related to Red Fir (Abies magnifica), which replaces it further southeast in southernmost Oregon and California, being best distinguished by the leaves having a groove along the midrib on the upper side; Red Fir does not show this. Red Fir also tends to have the leaves less closely packed, with the shoot bark visible between the leaves, whereas the shoot is largely hidden in Noble Fir. Red Fir cones also mostly have shorter bracts, except in Abies magnifica var. shastensis; this variety is considered by some botanists to be ahybrid between Noble Fir and Red Fir.
Eucalyptus delegatensis, commonly known as or Gum-topped stringybark or White-top,is a sub-alpine or temperate tree of southeastern Australia. A straight, grey-trunked tree, it reaches heights of over 90 metres in suitable conditions. The tallest currently known specimen is located inTasmania and is 87.9 m tall.
Among flowering plants, only the Eucalyptus regnans (Mountain Ash) grows taller, the Tasmanian Blue Gum, the Manna Gum, the Messmate Stringybark, the Shorea faguetiana, the Koompassia excelsa and possibly also the Eucalyptus nitens and the Allantospermum borneense about the same.
The bark is thick and fibrous at the base, smooth on the smaller branches. In the Tasmaniansubspecies, the entire trunk and the larger limbs are thick-barked; in the mainland subspecies the rough bark extends only part-way up the trunk.
The nominate subspecies is native to cool, deep soiled, mountainous areas between 850m and 1500 m in Victoria and New South Wales; E. d. tasmaniensis is found in most higher-altitude parts of Tasmania apart from the south-west.
Alpine Ash requires very high rainfall by Australian standards — over 1200mm (47 inches) per year and snow or frosts during the winter months. It is an important tree for the timber industry, often grouped with Mountain Ash, Messmate Stringybark and sold as Vic(torian) Ash or Tas(manian) Oak.
Alpine Ash regenerates only from seed. While occasional fires do not severely impact Alpine Ash forest, repeated fires in the same area can wipe stands out because it takes roughly twenty years for seedlings to reach sexual maturity.
Eucalyptus viminalis, Manna Gum, also known as White Gum, Ribbon Gum or Viminalis is an Australian eucalypt.
It is a straight erect tree, often around 40 metres tall, with rough bark on the trunk and base of larger branches, its upper bark peels away in long "ribbons" which can collect on the branches and surrounding ground . Occasionally it can attain very large sizes. The tallest currently know specimen is located in northeast Tasmania and is 89 m tall .
E. viminalis is widely distributed in the cooler areas of Australia where the leaves are the favoured food of Koalas . Sap has a 5–15% sugar content which makes it an essential part of the energy budget for arboreal or tree dwelling marsupial mammals like Yellow-bellied, Sugar and other gliders. Koala reintroduced to Kangaroo Island impact on native E. viminalis and is part of a AUD$4,000,000 management project from 2005-9.
There are three subspecies:
E. viminalis subsp. viminalis - NSW, Victoria, Tasmania, Mount Lofty Range of South Australia
E. viminalis subsp. cygnetensis - western Victoria, southeastern South Australia
E. viminalis subsp. pryoriana - southern Victoria
Timber is generally pale pink to pinkish brown in colour, often with distinctive light grey streaks. The attractive light pink tones of this species and its easy workability make it desirable in furniture applications. Structurally, uses are limited due to its low strength and durability, however some is used in seasoned and unseasoned house framing. Sapwood is distinct.
From its geographical distribution, it is unsurprising that it is hardy down to −15 degrees Celsius (+5 °F) or more making it suitable for planting in Europe.
