Mona Provisor


Contact Mona

As a lifetime Humboldt resident, Mona is delighted to have Trees Foundation as her first environmental non-profit job. Growing up in the hills of Southern Humboldt, her mom instilled in her the importance of community and our natural environment.

Today, the natural beauty of the local forests, rolling hills, creeks, and rivers are a large part of why she will continue to call this community her home.
In her free time she enjoys gardening, knitting, hiking, and rescuing recycling from garbage cans and the sides of roadways.

Ali Freedlund


Mattole Restoration Council

Ali has worked for the Mattole Restoration Council since 1996. At first, she concentrated her efforts on lessening the impacts from industrial timber harvest plans and the protection of Old-Growth forest stands. However, her job soon grew to incorporate different kinds of restoration projects from upgrading roads to reducing fuels, in her desire to protect and nourish watershed processes. Because Trees Foundation had long been a tireless supporter of MRC’s efforts, she did not hesitate when asked to become a member of their Board of Directors. She is pleased to be working alongside the dedicated and inspiring team of both the board and staff of Trees Foundation.
