Photograph 1: Giant Sequoia, Sequoiadendron giganteum, (Lindl.) J.Buchh. (sequoiadendron giganteum, 2017)
The giant Sequoia is the world’s largest tree it is native to California, when the tree is mature its bark is a red/ brownish colour. The physical characteristics of the giant Sequoia include, its ability to resist forest fires due to its extraordinarily thick bark which can grow to 6 meters wide, fire is a huge reason young giant Sequoia trees die. The bark of the tree is also resistant to fungi and wood beetles. The tree can resist windfall and its wood does not rot. Although fire can kill young giant sequoias, the tree largely depends on fire to release seeds from their cones and to eliminate its competition.

C. atlantica is found in the Atlas Mountains in North Africa and is part of the Pinaceae family. C. atlantica is a large coniferous about 30–35 m tall, the diameter of the trunk is 1.5–2 m. The tree is extremely similar to varieties of Lebanon cedar in all characters, the differences are hard to distinguish. The general cone size of a C. atlantica is …show more content…
libani is the national emblem of Lebanon. The conifer usually just has one single, thick trunk with many horizontal branches. The crown of the C. libani is cone-shaped however as it ages it tends to flattens. The bark of the tree is a greyish-brown colour. The leaves of the cedar of Lebanon are hardy with dark green to bluish/green needles about 3.5 cm long. On the shorter shoots of the tree the needles grow in groups of around 15 to 45. The cones of the C. libani are produced individually at the very end of the trees short shoots. The male cones are greyish/green or red colour and cylindrical shape, which are about 3 to 5 centimetres long. The female cones are rounded and measure 5 to 12 cm in length and 3 to 6 cm in width. The cones turn from green to brownish shade when they are
