Friends of the Urban Forest staff at a playground tree planting

by Mike Yarak, Urban Forestry Program Manager As manager of our urban forestry program, I’m often torn between pride in the positive impact we’ve made on the greening of San Francisco and a real concern that we’re not doing enough. Thanks to our dedicated staff, volunteers, and donors, we’ll be planting at least 1,100 street… read more »

Rebuilding our volunteer workforce is an urgent job

November 15, 2021
by Ben Carlson


by Susie Wasserstrom, Community Engagement Program Manager It’s a time of year for giving thanks, and I’m thankful that volunteers will soon be able to join our tree plantings again. We suspended planting trees altogether during San Francisco’s shelter-in-place order last year. When that was lifted, we got back to work with staff-only planting crews…. read more »

Preparing for a Dangerously Hotter Future

September 26, 2021
by Ben Carlson


The extreme heat events we’re witnessing in the West are frightening. We’re way past the point of a “wake-up call” when it comes to our rapidly warming planet. Science tells us that 20 years from now, extreme heat waves are likely to increase in San Francisco — and we’ll need to be ready. How are… read more »

As these fires become worse, it’s easy to feel helpless. Bringing neighbors together to plant and care for San Francisco’s urban forest is an… read more »

Trees aren’t the only things that produce oxygen and absorb CO2

July 25, 2021
by Ben Carlson


by Sammara Audi, Public Relations Intern As we all know by now, trees are amazing sources of oxygen, taking in carbon dioxide and releasing oxygen into the atmosphere via photosynthesis. Photosynthesis is the process of taking in carbon dioxide and water to produce glucose and oxygen as a by-product. It is primarily used by plants… read more »

by Sammara Audi, Public Relations Intern Trees are a vital part of our environment, taking in carbon dioxide and releasing oxygen to clear the atmosphere. They’re one of our main sources of oxygen and are essential for the survival of humans and wildlife. We get 16% of our overall oxygen from the trees and plants… read more »

A history of our relationship with San Francisco Public Works

April 19, 2021
by Ben Carlson


Forty years ago this year, the city of San Francisco cut the budget for the planting of street trees due to budget constraints. Five folks came together to start a non-profit to ensure that the city’s already meager urban tree canopy would continue to grow. Friends of the Urban Forest was born. One of the… read more »

Planting native vs. non-native tree species

October 31, 2020
by Ben Carlson


Very few of the tree species we plant are native; they include Coast Live Oak (Quercus agrifolia) and California Buckeye (Aesculus californica). But few tree species are native to San Francisco, and their populations were small; the western land was mostly sand dunes and the rest was mostly shrubs, grasses, and rocks. Monterey Cypress (Cupressus… read more »

Keeping your block beautiful

October 15, 2020
by Ben Carlson


San Francisco is a challenging place for street trees and sidewalk gardens because of our sandy or clay-like soils, strong salty winds, rainless summers, and many dogs. Even so, we have many mature and beautiful street trees and sidewalk gardens to learn from. We recommend: Regular watering helps plants and young trees (even drought-tolerant species)… read more »

Controlling pests the natural way

September 30, 2020
by Ben Carlson


A gardener’s knee-jerk reaction to pests (whether animal, insect, OR plant) is usually “kill it!” or “pull it!” — but is there a better alternative? Rather than pest eradication, let’s talk about pest management — specifically “integrated pest management” (IPM). IPM is a proactive system that strives to use a variety of pest control methods with… read more »
