Arborists try to clone John Muir's Bay area tree

MARTINEZ, Calif. (AP) — More than one hundred years after John Muir helped conserve thousands of acres of California wilderness, arborists are trying to clone a dying tree the naturalist brought to the San Francisco Bay area in the nineteenth century.

Arborists tell the Contra Costa Times (http://bit.ly/16jk16D) the tree Muir replanted on what is now the John Muir Historic Site in Martinez, Calif. is diseased. Muir brought it there from the Sierra Nevada almost 140 years ago.

A Michigan tree-cloning organization is now trying to turn more than 700 cuttings from the tree into a new giant sequoia — no easy feat. A giant sequoia has never been cloned before.

David Milarch of the Archangel Ancient Tree Archive has placed the cuttings in a capsule and controls their soil, water and air temperature. He has also treated them with hormones and antibiotics.
