David J. Mattson

What an impressive life he led. We need more "David Mattsons" in this world. He will be missed.

I just learned about David's work today. He clearly made important contributions in many areas. I was very sorry to learn of his passing. To his family and friends, I offer my condolences and very best wishes for peace and serenity.

We have lost a conservation giant, a human who knew that we and the wild ones share the planet as one. Condolences to Louisa and David's children.

I met Dave during the years he worked under Dick Knight at YNP, and was highly impressed by his out-of-the-box thinking and diligence in the field. Having been targeted by the Grizzly Bear Mafia myself, I well knew he challenges he faced, and through which he perervered. He was a fount of new insights, which he promoted despite opposition from pro-delisting forces. Within the past decade or so, his websites (e.g., AllGrizzly.org) have become the equivalent of textbooks on grizzly bear...

David worked with my father as a grad student at the University of Idaho College of Natural Resources, and those two spent quite a bit of treasured time in the field together working on white bark pine. My Dad had a lot of respect for Dave's intellect and work ethic. They became good friends and soon my mother also was introduced to David and became easy friends with him and his wife. Mom and Dad visited with Dave and his wife in Livingston and this is what my Mom said when I told her Dave...

We have lost a brilliant and courageous advocate for wildlands and wildlife who enriched our lives and whom we will miss. I send sincere condolences to Louisa and all of Dave´s family.

What a guy! Love and peace to his family.

To a life well-lived! You have been so admired.

Thank you Dave for helping to educate a green Yale student 25 years ago on the behavior of bears as well as the behavior of the humans they must coexist with....We will miss you down here.
