Native, non-native, and invasive. If you’re passionate about plants, you’ve probably heard these terms thrown around a lot. They’re used to describe the origins of different species, and often the connotation is that native plants are “good,” while other plants are “bad” or unwanted, and should be removed. But is this always true? Can plants…
If you live in Southern California, you’re probably familiar with the ubiquitous black mustard plant. Every spring, its bright yellow flowers blanket our hillsides, freeway medians, parks—basically, anywhere there’s a patch of dirt, mustard will grow. It’s a plant that thrives in disturbed areas—and unfortunately, it often disturbs the habitat around it, too. Considered invasive…
No child dreams of playing on scorching hot asphalt. And yet, more than 2.5 million K-12 students in California attend schools with less than 5% tree canopy in their play areas. Not only do green schoolyards enrich learning outcomes and improve mental health, they also provide life saving shade for our students and teachers. We…
Fire has always been a natural part of California’s ecology. But in recent years, climate change and decreasing biodiversity have resulted in more frequent and larger wildfires in the Angeles National Forest and the adjacent wildland-urban interface. That’s why on May 16, 2024, TreePeople and California Botanic Garden (CalBG) kicked off a $7 million initiative…
If you’re a homeowner, a landscaping professional, or someone who just cares a lot about the health of your local trees, you’re probably familiar with the practice of pruning. In its simplest form, pruning involves removing branches from a tree for a specific purpose. But how often should you be doing this? Which branches should…
Over 50 years ago, TreePeople began as a testament to the power of youth and we’re continuing to harness that spirit with our environmental education programming.
The year is 1970. At a summer camp in the San Bernardino Mountains, a 15-year-old “leadership camper” named Andy Lipkis learns that air pollution from the city is killing Southern California’s forests. It was a striking realization for the budding environmentalist—one that stuck with him until college, and inspired the school project that would change…
It’s been a wet, rainy winter here in Southern California, and as we look towards the warmer days ahead, nature-lovers are wondering — does that mean there’s another superbloom in store? The short answer is: it’s too soon to tell. While rain can help usher in the dramatic floral displays that blanket our hillsides in…
In the preface to Claire Latané’s Schools That Heal, she reminds us that “It is hard to make healthy schools. Even in neighborhoods that have plenty of resources, most school environments fall short of supporting students’ mental and physical health and well-being.” TreePeople’s School Greening initiative aims to collaborate with school communities to reimagine how…
In a world glued to screens and constant connectivity, it’s not just a feel-good myth—nature’s got some serious perks for our well-being. Besides the “get off your phone” and “touch grass” cliches, science backs up the fact that spending time outdoors can benefit your health. We’ve compiled a non-exhaustive list of ways that nature can…
Have you noticed red berries around southern California lately? Chances are they might belong to heteromeles arbutifolia, a California-native shrub also known as toyon or “California holly.” Toyon — a perennial found throughout western California and the Sierra foothills — has dark green, toothed leaves and white flowers in the summer that yield to red…
The urban forestry community lost a giant with the sudden passing of Jarlath O’Neil-Dunne on January 6. Jarlath led a globally respected lab that used high-resolution imagery of the earth to map land cover in our complex urban landscapes at fine level of detail with astounding accuracy. The work of Jarlath’s Spatial Analysis Lab at…
