As we pull our bins of tradition out from the basements, attics, and other cool, dark corners of our living spaces, we start to wonder how we ended up doing the things we are doing. As you decorate your trees this year, it might be nice to understand where that comes from.

Evergreens have consistently been used to celebrate throughout history. Festivals and feasts were held for the winter solstice. In ancient Egypt, it denoted that the sun god Ra was recovering from illness. In ancient Greece, the festival Saturnalia was held in honor of Saturn, god…

Hi again! Last time I went through my first three, “what I have learned about urban soils” in my over 30 years of research. Here I present three more:

4. Spatially, urban landscapes represent a “new heterogeneity” of soil characteristics

As I pointed out in my previous blog, there’s a new paradigm in pedology (a branch of soil science focused on the formation of soil, its characteristics, and classification) where humans are now considered as a separate soil forming factor, which really regulates the “health” of the soil found in…

TreePeople has been distributing fruit trees since 1984, focusing on areas of LA County known as food deserts. These areas have limited access to grocery stores selling fresh fruits and vegetables and include South LA, Southeast LA and the Northeast San Fernando Valley. Home-grown fruit makes a positive difference in the lives and health of people, so distributing fruit trees to communities throughout Los Angeles has always been an important part of TreePeople’s work.

When choosing fruit trees for your own home, there are certain terms that are specific to fruit trees and are used on the…

I have been involved in conducting research in urban ecosystems for over 30 years. And while I was pulling together a presentation for a recent virtual symposium on urban soils (Los Angeles Urban Soil Symposium) hosted by TreePeople, I asked myself, what in a nutshell have I learned about urban soils during that time? Well, I tried to keep it within 5 topics, but in the end I came up with 6. In part 1, I cover the first three. Here they are:

1. Cities are the answer to continued…

The Chaparral Needs Your Help… And Together We Can Fight Fire

By Adam Corey Thomas

It is 2 am on an unpleasantly warm but predictably unnerving autumn night. The Santa Ana winds are roaring through the hills and valleys of Southern California. Throughout Los Angeles, residents are on edge. It is not the wind that they are afraid of, even though it does have a role to play. It is fire. Angelenos are used to this threat, but now the danger has never felt so close and so extreme.

One mother described carrying her child over flooded streets so their clothes wouldn’t get wet before school. Another worried that the chemicals and trash that linger in that same floodwater could contaminate their tap.

Many others found that they had similar concerns — and they all agreed to work to do something about it.

The Pacoima residents — along with about 20 others — had gathered in an online Zoom meeting for a WaterTalk held by TreePeople. …
