TreePeople’s Most Wanted: Mountain Edition

We’re back with another round of California’s most wanted invasive plants.

This time we are looking to our local mountains in the Angeles National Forests and Santa Monica Mountains to learn about the top five worst invasive species that we tend to find during our mountain restoration events. These plants out-compete our native plants and create huge fire hazards in our already drier than normal hillsides

#1 Ripgut Brome (Bromus diandrus)

This pesky plant quickly spreads and infiltrates its surrounding areas.… Read more >>

Sunburned This Summer? So Are the Trees!

Driving around LA you may have noticed trees and plants all over town with entire areas across their canopy covered with dried, brown leaves. This sunburned effect can be caused by a combination of the angle of the sun and extreme heat, burning some, but not all the leaves.   

This unusual combination occurred when record-breaking temperatures over the course of two days – July 6 and 7 – hit 108° in the downtown area, and rose to 117° in the valley.… Read more >>

Trees, Art, Sam Francis and TreePeople

It’s beautiful to see how nature helps pave the paths of those who inspire our lives.

TreePeople’s Founder and President Andy Lipkis was a forward-thinking youth who began an environmental nonprofit at the age of 17 after being inspired by the dying trees in the Angeles National Forest. Similarly, Sam Francis, one of California’s most influential abstract expressionist painters with art hanging in LA museums like the Broad and the Norton Simon Museum, also drew inspiration from nature in forests, lakes, rivers and the ocean while living around the San Francisco Bay Area.… Read more >>

TreePeople’s Most Wanted: Home Edition

California’s native plants are under attack.

From our mountain habitats all the way down to our very backyard, invasive plant species are taking over. According to the U.S. Government, an invasive species is one that is non-native to the ecosystem and one whose introduction causes or will likely cause economic, environmental or human-health harm.

Invasive plants can often outcompete our natives because they don’t have the checks and balances they would have in their native land. Often this freedom leads them to grow faster and spread faster than the native plants they are replacing.… Read more >>

Make Your Voices Heard: Urban Forest…Stand Up for Trees

Did you know that you actually live in an urban forest? 

An urban forest is made up of a network of publicly and privately-owned trees and forests in and around cities. At its core, the urban forest connects, nourishes and optimizes the health and functionality of the city and those who dwell in it.

Unfortunately, LA’s urban forest is often seen by some as merely street trees or parks that simply add beauty. Therefore, the real value of the urban forest is not fully recognized so it does not receive enough funding, protections, or maintenance it needs to thrive and protect the lives and health of all Angelenos.… Read more >>

These Heat Waves Kill

They say some like it hot, but as the first significant heat wave of the season hits this week, many Angelenos will wish it was winter.

According to the Centers for Disease Control and Prevention, each year extreme heat causes more deaths in the United States than all other weather-related causes combined. In LA, the average five-day heat wave results in 4.1% more deaths than cooler weather on the first day, and 11.9% more on the fifth day.

Realistically, the coming heat event will result in some Angelenos going to the emergency room…and others dying at home.… Read more >>

A Wildfire Safety Guide

The increasing threat of wildfire is Southern California’s new climate reality and it’s impossible to ignore.

Hotter summers and drier winters lead to more events like the 2017 Thomas fire – the largest wildfire in California history that wreaked havoc well outside the range of what used to be fire season.

With this season’s rain totals being over 65% below normal, the fire outlook for the rest of 2018 is looking increasingly dire.

In times like these, it is imperative that residents who live in fire-prone areas stay prepared.… Read more >>

The 4 D’s: Dead, Diseased, Damaged, or Deranged!

Dead, diseased, damaged, or deranged – think this is not the description of a horror film character? Guess again!

At TreePeople, and in the field of arboriculture, they are known as the 4 D’s. It is the simple way to remember what to prune out of a tree to help ensure it is happy and healthy!

To Prune or Not to Prune

More often than not, trees are over-pruned. Unfortunately, most people believe that a tree must be pruned every year – like getting a haircut.… Read more >>
