New Book On Women in American History

The role of women in history, science, and culture often goes unheralded. I'm proud to announce that I contributed to a new four-volume reference book now available from ABC-CLIO Publishing.

Women in American History: A Social, Political, and Cultural Encyclopedia and Document Collection 
edited by Peg Lamphier and Rosanne Welch
Available in the Spring 2016 catalog:

More than a standard encyclopedia, it brings together the women, movements and original documents connected with social change, court cases, science and culture. You might know the role Rachel Carson played in alerting the public to chemical toxins and inspiring the modern conservation movement, but did you know her earlier work The Sea Around Us sold more copies than Catcher in the Rye in 1951? She encouraged average people to be interested in science.

Did you know that your cell phone depends on science developed by Hedy Lamarr, a woman most known for starring as a sex kitten in Hollywood movies from the 1940s. Her beauty made it difficult for her to be taken seriously as an inventor.  

It's time to peel back the misconception of "women's roles" and understand the influential positions women held in pre-Revolutionary America, the true social status of Native American women prior to the erosion of their original cultures, and the influence of female French colonists in North America. How did women of all race contribute to politics, business, culture, and science help to build modern society? What can we learn from them and use to build a better future?

Finding The Positive in Los Angeles - The River and Local Wildlife

Los Angeles River west of Balboa Blvd.
On a day like today, following another mass assault on our own humanity, it can be difficult to see the world as a positive place. But we all have a choice and I choose to reach out to people making positive differences in the world. 

Los Angeles River just above Sepulveda Dam
Walking the Los Angeles River we have seen the neglected waterway being embraced and re-imagined as part of our communities. The neighborhoods we have walked through so far have been as varied as the River. We all should step out of our own neighborhoods more often to understand the lives of people we think are different from ourselves. The L.A. River holds the potential of uniting disparate peoples across a large city.

The River also can connect disengaged people with the natural world. The section through the Sepulveda Basin is wildness contained, a place to experience wildlife in the city.


Channel Island fox
The non-profit that I work with, Friends of the Island Fox (a program of the Channel Islands Park Foundation) has just wrapped up a year of numerous successful efforts to support island fox conservation. The Channel Island fox has made a strong recovery from the brink of extinction because of the determined efforts of local people.

There is much to celebrate, but too often it is overshadowed by mindless tragedy caused by people. Today I reject fear and pledge to reach out and build connections with more of my neighbors. Safety doesn't come through weaponry, it comes through bonds of respect and understanding.

Walking the Los Angeles River

Water is life giving. The current drought should be making us more respectful of the naturally occurring water in southern California. Still many people laugh when Angelenos say we have a river.

The Los Angeles River was the center of human habitation in this area for thousands of years. When it created havoc and catastrophic flooding, people confined it to a concrete pathway in order to control its unpredictable ways.

Finally, fear is giving way to respect and a desire to allow the River to reconnect with its natural ways. The L.A. River officially begins in Canoga Park, less than two miles from where I grew up and I've always wanted to think of it as a river rather than "a wash" or storm drain.

We've been venturing down to the L.A. River for the past nine years. Gradually, new parks and pathways are inviting the public to rediscover the River. See the L.A. River Headwaters walking path.

I've been birding the L.A. River in the Sepulveda Basin for years. It is a gem of wildlife habitat surrounded by suburbs. Wouldn't it be wonderful if the whole L.A. River could become a ribbon of life winding its way through the city? 

I've gotten this idea that I want to walk the River from its birth as a trickle of water in the surrounding mountains to its eventual arrival at the sea.

So far I've walked sections from the trail along Bell Canyon Creek to the mid-valley at Tampa.

Exploring the River is also seeing the land change, the neighborhoods change, and thinking about the city in new ways. Today, friends joined me in walking the River from Winnetka to the footbridge at Vanalden St. We saw thirteen species of birds and a variety of wildflowers on the native plants landscaping the bikeway. Check out my friend Doug Welch's flower photos on his blog. 

There is a river near you and it is worth exploring.

Fall is Time to Plant CA Native Plants

deer grass from SB Botanic Garden
Two weekends ago, we took a ride up to the Santa Barbara Botanic Garden for their fall native plant sale. 

Native plants can stand up to drought, but now is the time to plant those plants. If the rains really do come, it will give your native plants a jump on survival. For us, it is also about maintaining the stability of our hillside. 

I've been planting, planting, planting.

Calliandra from seeds
Even some of the seedlings I started this spring are going into the ground.

The Botanic garden also had a  cross-over art event, a fiber arts installation organized by Yarn Blaster Babes. 

Check out our Earth Minute videos of the installation How Do Trees Dream? and a school project that displayed How Tall is a Redwood Tree?

This creative installation reminds us all to play. Explore trees, plants, and flowers. Don't just look, interact. A new viewpoint may open up some other aspect of your life. The solution to that work challenge might be found while playing in the garden. Gardens don't have to be big; make a mini-garden.

The Santa Barbara Botanic Garden plant sale continues through the end of the month. What more can I say? GO.

CA Native Plants Standing Up to Drought

The drought continues to be a challenge for all of Southern California, but I was heartened this morning by the survival skills of some of my native plants. 

It is October 1, but these plants are looking well.

Video - Take a look at the variety of adaptations in their leaves.

San Nicolas Island buckwheat
Many of the Channel Island species, especially those from the southern islands, are thriving. The San Nicolas Island buckwheat (Eriogonum grande timorum) continues to bloom and to reseed itself, while the San Nicolas Island chamise (Adenostoma fasciculatom 'Nicolas') is a rich green.

Now is the time to plant California native plants so they can establish themselves over the winter. In October, numerous native plant growers are offering special sales:

Now's the time. Plant those natives!

Ring-necked Snake in the Garden

ring-necked snake
Creating habitat in your yard means inviting in predators as well as prey. You can't have healthy equilibrium without creatures at all levels of the food chain.

One of our predators isn't large or threatening, but it is important. We happened upon this juvenile ring-necked snake (Diadophis punctatus) spending the day between rocks at the bottom of the fence. See video of this snake on

Though small in size (typically 30-90 cm) the ring-necked snake is an important predator of small creatures, notably salamanders and lizards in its western distribution. We have both, especially a growing population of western fence lizards. We noticed a couple of years ago that the explosion of young fence lizards had slowed. Around that time came my first observation of a ring-necked snake. Not long after, I found the remains of one that had been eaten.

This snake species is found across North America. The eastern population tends to be smaller with a yellowish belly, while the western population has a bright red belly. In both cases this bright coloration is flashed at would-be predators to scare them off. The color red is often found in nature as a warning color suggesting venom or poison. There are theories that the red scares scrub-jays which might potentially eat these small snakes if they found them in the leaf litter. 

The ring-necked snake is a member of family colubridae, the most numerous group of snakes. Most are harmless to humans. The large eyes indicate that this snake is a visual hunter and as a colubrid with a long thin, fast body, it most likely tracks down its prey. 

Lizards and amphibians can be tricky to catch and subdue. The ring-necked snake is one of many colubrids which is now known to have venom delivered by fixed fangs at the back of the mouth. The venom delivery system has evolved for prey like lizards. The snake bites the lizard, holds on and moves the mouth back and forth to work the venom into the struggling prey. The nature of the venom and the manner of its delivery makes most rear-fanged venomous snakes not dangerous to humans. This little snake does not want to use its valuable venom on a human or a bird predator, that is why it has the warning coloration on its belly. "I could bite you scrub-jay, but I really don't want to. Leave me alone."

We gently relocated the ring-necked snake to the other side of the yard while we were working on the fence. We hope that it stays and continues to live in our yard. Small, unassuming predators like the ring-necked snake are vital to biodiversity and habitat balance. Would you believe that a study of density, found a healthy ecosystem could have 719 - 1,849 of these small snakes in an area the size of two football fields? And most people would have no idea they were there.

Make a Fairy Garden

Between pocket gophers and the drought, I admit I'm garden weary. 

I needed a garden success so I redid my mini-gardens.

Take a minute and let's redo a mini-garden together.

If you are garden weary too, you might also visit a public garden or local California wild place. 

Hidden Gardens of Los Angeles and other California wild places on The Earth Minute

Visit for inspiration or a bit of nature's calm and let someone else worry about the watering.
