This group is based on a simple idea -- after-work drinks and some conversation. We bring together professionals (whether working in the environmental industry or not). Most events have a real turnout of 8-15 people, with a healthy mix of returnees and new-comers. If you're curious, come check out an event!

We hike in Marin, an outdoor paradise; where every hike may become your new favorite hike. With over 600 miles of trails, it's a hikers dream and local to the San Francisco Bay Area.

More than ever before, we must explore innovative, strategic ways to ensure the protection, safety, and welfare of cetaceans, and restore the …

A "weed" is just a plant out of place. "Weed Warriors" remove invasive plants that ruin wildlife habitat, increase fire danger, take over and crowd out everything else, or are otherwise bad actors in East Bay natural areas. "Friends of Five Creeks' Weekday Weed Warriors" remove harmful invasive plants in natural areas 10 AM - noon Tuesdays, at a different restoration site each week. Usually, work is followed by coffee and chat. Great way to stay fit and enjoy the outdoors and good company while …

We're lively, sweaty folks from throughout the East Bay and beyond who get together pretty much every week to remove invasive weeds and replant native species in Redwood Regional Park, the Sausal Creek Watershed, Sibley and Huckleberry Regional Parks, and adjoining open space and wild lands throughout the Greater East Bay Hills Ecosystem. We help beautiful native plants and wildlife return to places from which they had been absent, get lots of fresh air and exercise in the process, and have grea …

Bioregionalism is a concept that goes beyond national boundaries, but rather is a political, cultural, and ecological system or set of views based on naturally defined areas called bioregions, similar to ecoregions. Bioregions are defined through physical and environmental features, including watershed boundaries and soil and terrain characteristics. Bioregionalism stresses that the determination of a bioregion is also a cultural phenomenon, and emphasizes local populations, knowledge, and solut …

"Find your place on the planet. Dig in, and take responsibility from there" - Gary Snyder Don't let the weeds take over our mountain! Not only are they ugly and prickly, but they're also changing our mountain: more weeds = less wildflower + more fires. The vast majority of the mountain is in good shape but the nasties are starting to take hold and move around. Let's stop them before they really get going. Say it with me, pulling broom is fun oh so fun oh so fun, I wanna do this all day long... M …

Bottled water corporations are trying to change the way people think about water. Water is a human right and common resource, not a commodity to be bought and sold. By retailing and promoting bottled water in our national parks, the bottled water industry is attempting to paint its eco-unfriendly product green. Our national parks were never meant to serve as billboards and concession stands for the bottled water industry. It sends the wrong message about our national commitment to water, our mos …

What if you could get rewarded for being the incredible eco-conscious and community-enthused person that yo …
