Betula pendula (as "B. oycoviensis") was previously listed on the Red List as vulnerable, though it is now considered a synonym of "Betula pendula" subsp. "pendula". "Betula szaferi" was previously considered extinct in the wild on the Red List, but is now considered a form of "B. pendula" with the presence of a mutant gene, causing it to grow weakly and fruit heavily. Silver birch is often planted in parks and gardens, grown for its white bark and gracefully drooping shoots, sometimes even in warmer-than-optimum places such as Los Angeles and Sydney. In Scandinavia and other regions of northern Europe, it is
Cunninghamia vegetative propagation for use in forestry plantations. As the tree grows its trunk tends to sucker around the base, particularly following damage to the stem or roots, and it then may grow in a multi-trunked form. Brown bark of mature trees peels off in strips to reveal reddish-brown inner bark. Older specimens often look ragged, as the old needles may cling to stems for up to 5 years. This tree can be mistaken for the rare "Torreya taxifolia", one visible difference being the "Cunninghamia"'s bronze autumn branches which are shed and pile beneath it, as well as the propensity for
