You won’t see it if you’re not looking for it, but you’ll know it was there. No bigger than a baby’s fingernail, the gold-spotted oak borer (GSOB) can devastate a 300-year-old oak tree that has withstood storms and quakes and even the quick and astounding rise of urban pollution in the 20th century. But if individual trees were all that was at stake, the oak borer wouldn’t pose such a threat. The truth is, this invasive pest could wipe out every native oak in California.… Read more >>
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.
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 >>
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 >>
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.
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 >>
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 >>
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 >>
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 >>
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 >>
You may have noticed that some years in Los Angeles County are wetter—or drier—than others. And in wet years you may also have noticed a lot of unfiltered water rushing off paved surfaces, into storm drains, and out to sea carrying whatever pollutants it washes over. So, not only are we losing water that could be captured for local use or returned to the ground for irrigation, we’re failing to clean it up before it enters our waterways.
But did you know that even in times of drought, what little moisture falls from the sky can be harvested and put to use?… Read more >>
