L. Martin Griffin

Griffin has been widely honored for his decades of environmental work in helping to preserve numerous sensitive wildlife habitats in Sonoma and Marin County. He lives in Belvedere, California, and turned 100 in July 2020.

In another media appearance, Griffin was interviewed for, and appears in, a documentary film on the history of the successful effort to save Marin County land from development, Rebels with a Cause. The film, narrated by actress Frances McDormand, was released in June 2013. The movie was produced by Nancy Kelly and Kenji Yamamoto, and has been described by the Marin Independent Journal as "powerful" and "generating a strong buzz" during a lengthy run in Marin.

In August, 2012 Griffin again weighed in forcefully on the issue of the commercial shellfish farming business. Writing in an op-ed in the Santa Rosa Press Democrat, Griffin was direct in his opposition to the continued operations of the Drakes Bay Oyster Company: "Sen. Dianne Feinstein has continued political obstruction on behalf of the company in this nationally significant policy decision, and it must stop." He noted "This year is the national seashore's 50th anniversary. Let's not drive a stake through its ecological heart, but rather honor the legacy of John Muir, Clem Miller, Peter Behr and others, and let the estero go wild."

Griffin's advocacy efforts, as well as those of others, were vindicated when U.S. Interior Secretary Ken Salazar declined to renew the oyster farm lease in November 2012. Asked in February 2013 for comment on a federal judge's refusal to issue an injunction to continue to allow the operation of the farm past the March 15 deadline for removal of all farm equipment, Griffin said "It's been a long battle, the judge studied it very carefully and I think she made the right decision." The cleanup of the farming operation was completed in May, 2017.

Noting the need for secrecy in preventing development, Griffin observed in 2010 that "We had to keep all the operations very secretive because once someone else found out what you were up to it was trouble."

The executive director of Audubon Canyon Ranch, Scott Feierabend, commented in July 2010 that Griffin's work to save the coastal areas of Marin and Sonoma Counties was crucial, stating to the Marin Independent Journal "He saw that the whole coastlines of Marin and Sonoma were such a treasure. He understood if he could acquire keystone properties along the coastline they would be impediments to any linear construction."

Into his 90s, Griffin continued to speak out about conservation issues. He criticized efforts by Senator Dianne Feinstein to allow the continued operation of a shellfish farm and tasting bar in the Phillip Burton Wilderness, a sensitive coastal area of Point Reyes National Seashore. Writing a featured commentary in the Marin Independent Journal in 2009, he asked "Why protect Drakes Estero? It shelters the largest rookery of breeding and pupping harbor seals on the north coast. It is a vital nursery for ocean fish. It is refuge for migratory ocean birds, its shoals home to countless invertebrates nourished by tidal water from the ocean. It is a magical, isolated, historic inlet on the wild, rugged coast."

Griffin was also active in Sonoma County where he owned the Hop Kiln Winery. He lived in Sonoma County from 1974 until he moved back to Marin thirty years later. He helped establish the Bouverie Audubon Preserve with a gift from David Bouverie. Griffin also co-founded the Friends of the Russian River to preserve the Russian and other rivers in California from logging, gravel mining, dams and destruction of riparian habitat. He was instrumental in establishing the Griffin Russian River Riparian Preserve and Gina's Orchard Preserve.

Griffin played a substantial part in establishing wildlife sanctuaries along Richardson Bay, working with and learning from environmentalist Caroline Livermore. Their work helped prevent the filling in of the bay and tidelands for a housing development. Griffin took note of Livermore's strategy of raising money to purchase sensitive areas threatened by construction. Using the same tactics, Griffin worked to prevent development in and around Bolinas Lagoon. In 1962 Griffin wrote a personal check for one thousand dollars (which he was unsure he had the funds to cover) to put a hold on the key property called the Canyon Ranch (now Audubon Canyon Ranch) that was for sale for $337,000. He then solicited help from chapters of the Audubon Society to raise the rest of the cash.
