Wo findet man Mammutbäume?
Sierra Nevada
Die meisten Mammutbäume stehen in der kalifornischen Sierra Nevada oder an der Küste zwischen Los Angeles und Seattle. Dort gibt es ausreichend Wasser und mildes Klima – ideale Verhältnisse also, um so gewaltig in die Höhe zu schießen.
Was für ein Durchmesser hat ein Mammutbaum?
Im Alter von rund 1.500 Jahren erreichen sie etwa 110 Meter, das entspricht der Höhe eines 25-stöckigen Hochhauses. Das größte Exemplar ist wohl 135 Meter hoch. Ihr Stamm hat einen Durchmesser von fünf bis acht Metern. Die ältesten Riesenmammutbäume sind rund 3.600 Jahre alt.

Learn more about giant sequoias, climate, and on-going research. Giant sequoias in Redwood Mountain Grove, Kings Canyon National Park. Sequoia on right side has a large fire-scarred black surface from a lifetime of periodic fires. Fire plays a crucial role in the giant sequoia ecosystem.
Do sequoias grow well in the Pacific Northwest?
The tree does not appreciate too arid soils or humid, hot summers. Giant sequoias are very successful in the Pacific Northwest from western Oregon north to southwest British Columbia, with fast growth rates.
What does the bark of a sequoia tree look like?
The giant sequoias’ red/orange bark is distinct among the grey and brown bark of other trees. And if you stand beneath one of these giants, you can gaze all the way up its tall trunk and through its high branches to see sky above. The treetop is often hidden above the highest branches.
How are giant sequoias adapted to fire?
Giant sequoias are adapted to periodic fire. Sequoia bark typically protects the trees against significant damage. At up to 18 inches (46 cm) thick and extremely fibrous, sequoia bark not only resists burning but also insulates the tree against fire’s heat. Should fire penetrate the bark and scar the living tissue, new growth may heal the scar.
