From his home base in Sonoma, Dr. Rodney Jackson reaches halfway around the world to protect the endangered Snow Leopards of the Himalayas.

For almost three decades, Dr. Jackson, a zoologist, has played a leading role in the study of the elusive high mountain snow leopards. He explains how it has progressed over the years.

Snow leopards are notoriously shy, as Jackson details, but they are surprisingly available to be seen at zoos across North America, including in San Francisco, where a new habitat was recently constructed for their active breeding pair.

Dr. Jackson has recently developed the Long Tail wine label, selling high quality Sonoma County varietals as a fund-raising tool for the Snow Leopard Conservancy.
