"Josiah completely exceeded my expectations. Massive amounts of invasive plants have been removed from my 1/2 acre property. They've been replaced by naturally occurring plants specifically for this habitat. Josiah always takes time to explain everything he is doing and the reason behind it. He's also one of the top birders in California and an amazing naturalist. I have learned so much from him about botany, entomology, bird nesting preferences, and frogs and reptiles. As my plants mature, I will have a pollinators' paradise. One small thing I can do for the planet thanks to Josiah and his team."

–Janice, Bolinas CA

"A special page in our Josiah Clark file, here at the Mill Valley house, is a list he made for us some years ago:  species of birds on our property. This “bird list” is typical of what we learn about the Nature around us, just incidentally, each time we have a contract with Josiah."

–Steinbeck, Mill Valley CA
