ColdwaterParkPlanting_5-26-2011_ZTaylor_c2DSC_6317_sm

Coldwater Canyon Avenue will be CLOSED between Ventura Blvd. and Mulholland Drive, from March 23 to April 25, 2013. We hope you’ll try these alternate routes so you can still enjoy our hilltop park:

Cahuenga Blvd./Highland Ave.
Laurel Canyon Blvd.
Beverly Glen Blvd.
Sepulveda Blvd.
Interstate 405

The road is closing because the Los Angeles Department of Water and Power (LADWP) is continuing its City Trunk Line replacement project. The next construction phase will require the full closure of Coldwater Canyon Avenue.… Read more >>

Three Big Days, One Simple Act


While April 22 is just around the corner and Earth Day is a wonderful time to reflect and celebrate this incredible planet, this month there are two other days that highlight hugely important environmental issues. March 21 is International Day of Forests and March 22 is World Water Day.

How to celebrate? After all, these days commemorate such enormous global issues. If I had to choose one action, it would be this: plant a tree.

With the simple act of planting a tree, each of us can help maintain the urban forest and shift the water crisis, all with one easy but profound step.… Read more >>

Human Help Needed to Restore Nature to the Angeles Forest

Angeles4-frame_cga3-19-2013

The devastating Station Fire of 2009 destroyed 160,000 acres of wilderness in the Angeles National Forest in the mountains surrounding Los Angeles—and fully 11,000 of those acres burned too deep in the soil for natural seed regeneration. So every season TreePeople and the U.S. Forest Service need lots of extra hands to help plant trees while the soil conditions and temperature are optimal.

We’re in the third planting season with our partners at Forest Aid: Angeles. To meet our 2013 goal we must plant 5,000 more seedlings than last year—for a total of 15,000 new trees.… Read more >>

How TreePeople Catches Every Drop

Jim Hardie, TreePeople 216,000 gallon cistern

Is Los Angeles a desert? Our city gets about 15 inches of rainfall annually, slightly more precipitation than, say, Missoula, Montana (though we have fewer days per year that are considered “wet”). Did you know this is enough to serve a fairly large population and irrigate its urban greenery?

But every time it rains an inch in the city of L.A., 3.8 billion gallons of runoff are sent to sea, sweeping trash, toxins, and bacteria into waterways and polluting our beaches and ocean.… Read more >>

Grow a Fruit Salad on a Single Tree

Picture 034_sm

Want to grow a fruit tree, but can’t decide which one? Wouldn’t it be great to have more than one type of fruit on a single tree? It’s possible to have this “fruit salad” effect in your backyard with the amazing technique of grafting.

Grafting is the process of splicing a branch or bud from one tree onto another tree. Grafting deciduous trees (trees that lose their leaves in winter) is done in winter when the trees are dormant, or leafless.… Read more >>

What Kind of Tree Is That?

Ever notice the trees in your neighborhood?

Maybe they are spectacular specimens with giant canopies that shade the streets and make you want to be a kid again and climb to the top. Or maybe they are small, under-cared for, half-dying trees, and it’s not even clear what kind they are.

More than likely, it is a mix. And that’s where two of TreePeople’s programs can really help out. Our tree care program is extensive. At TreePeople, when we plant a tree, we stay with it for a full 5 years to care for and maintain it until it is established.… Read more >>

Western Redbud: “A tree with year-round interest!”

Photos: Bob Sussman (left), Stan Shebs (right)

Why is the Western redbud (Cercis occidentalis) the best tree ever? Maybe it’s because at this time of year, redbuds are the focal point of any garden lucky enough to have them. This native Californian is a small tree (15–20’ x 15–20’) and does well in most any kind of soil, as long as it is well-drained.

In the late winter and early spring, when most everything else is still dormant and waiting to bud, the red bud has spectacular magenta flowers that are delicate and yet very resilient to cold, wet days.… Read more >>

Not your typical field trip: 500 students win a chance to replant the Angeles National Forest

Angeles2_crop

Students from 10 Los Angeles area middle and high schools learned this week that they were winners of sponsored field trips to the Angeles National Forest to help restore fire-damaged areas of one of Los Angeles County’s largest preserved open space.

The Facebook-based contest TreeByTree was a collaboration between TreePeople and Edison International. On a weekly basis, students from 17 schools posted photos of sustainability-minded projects they spearheaded, from recycling programs to tree plantings to converting a vintage VW Bug to electric.… Read more >>

A Valentines Day tour of your local sewage treatment plant?

Seeking inspiration on how to spend Valentine’s Day?  Check out this idea: Brooklyn Sewage Treatment Plant to Hold Valentines Day Tours Again.

What makes this such a sell-out event on the other coast?  NPR reported that perhaps it is the pheromones that makes this unusual tour part of the hipsters’ bucket list, but maybe it’s more.

Maybe people are really wanting to connect with each other about things that matter…like the quality of our water.  Maybe Super Storm Sandy is making folks want to get a bit more eco-literate and brush up on the water cycle info they got back in 6th grade science class.  Or maybe it is the amazing view of Manhattan.… Read more >>

When Trees Thrive, People Thrive

We at TreePeople certainly believe that what we are doing is a matter of life and death. But sometimes we’re confronted with more sobering proof than we expected. That’s what happened when I read this article by Lindsay Abrams that recently appeared in The Atlantic, “When Trees Die, People Die.” 

I expected that this article would be just another “trees-make-us-feel-better” story. “Aren’t they pretty? Let’s go plant some.” I wasn’t prepared for this (italics mine):

When the U.S. Forest Service looked at mortality rates in counties affected by the emerald ash borer, they found increased mortality rates.… Read more >>
