Endangered Species Day: May 21, 2021 - California Tiger Salamander

Celebrate the 16th Annual Endangered Species Day on May 21st, 2021. Every year on the third Friday in May, thousands of people around the world participate in Endangered Species Day by celebrating, learning about, and taking action to protect threatened and endangered species.

In honor of Endangered Species Day, we would like to introduce the adorable California Tiger Salamander! The California Tiger Salamander is a threatened and endangered amphibian species native to California. This spotted salamander enjoys munching on snails, insects, earthworms, and even small fish!

National Wildflower Week: May 3 - 9, 2021 - Create a Pollinator Garden

The first full week of May is National Wildflower Week, May 3 through 9 this year. It is a time when gardens are blooming with flowers.

Pollinators visit flowers to drink nectar or feed off of pollen and transport pollen grains as they move from spot to spot. Birds, bats, butterflies, moths, flies, beetles, wasps, small mammals, and most importantly, bees are pollinators.

Pollinators play a crucial role in flowering plant reproduction and in the production of most fruits and vegetables. Without the assistance of pollinators, most plants cannot produce fruits and seeds. The fruits and seeds of flowering plants are an important food source for people and wildlife.

A wonderful way to support local pollinators is to create a pollinator garden.

National Wildflower Week: May 3 - 9, 2021 - The Value of Native Plants

The first full week of May is National Wildflower Week, May 3 through 9 this year. It is a time when most of the country is ablaze with springtime blossoms.

While taking a walk around your neighborhood or driving along the freeway, a patch of California Poppies, with bright orange petals and lime green foliage, might catch your attention.

The California Poppy is the state’s designated flower, and it’s a shining example of California’s amazing collection of plants.

California has the highest number of native and endemic plants than any other state. It is estimated that the state is home to 6,500 species, subspecies, and varieties of plants, many are not found anywhere else on the earth! 

Why does California have so many plants? Well, California is actually a global hotspot for biodiversity. The state’s variation in landscape features, latitudinal ranges, minerals, soils, and climate result in a wide range of ecosystems that can support many plants as well as animals. Most of the state lies within the California Floristic Province, a portion of western North America having a Mediterranean- climate (dry summers and mild, wet winters) with high levels of plant diversity.

You can view photos of each of these gardens, read a description of the garden and print out its plant list at View the 2021 Gardens. You will be able to meet the homeowners and view about half of these gardens live online through Sundays in the Gardens.

This program will be hosted on Zoom, and live-streamed on YouTube. Registration is required. Click here to register for the online tour. Your registration email will contain links to join the live events.

The exemplary landscapes on the Tour hope to inform, inspire and motivate you to incorporate native plants into your own gardens. They contain at least 60% native plants, are pesticide-free, water-conserving, and provide habitat for wildlife.

Renowned ecologist and best-selling author Douglas Tallamy will open this event on Sunday, April 25, at 10:00, after which each garden owner will host a 25 minute long live visit.
