Eucalyptus is a diverse genus of flowering trees which dominate the Australian tree flora. Commonly referred to as "eucalypts" or "gum trees" this genus contains approximately 700 species. From fossil records it appears eucalypts became dominant in Australia in response to a sudden geological increase in fire frequency. Over time resilliant adaptations to drought, bush fires, and biological attack allowed the eucalypts to survive well. Common adaptations include: hard wood leaves, which effectively resist drought making it easy to conserve water in times of stress; dormant buds under the bark for sprouting after destructive canopy events; seeding mechanisms which release seeds after forest fires; and large nutrient storing roots (lingo tubers) allowing regrowth in times of excess damage. To combat insect, fungal, and termite attack eucalypts produce extractives which give the timbers such varied properties and colours. The generally slow growing nature gives rise to the high density of the timber. It's because of these features Eucalypts are so visually stunning and strong.
