Los Angeles is Being Invaded by Frogs!

Sunday, September 6, 7:54 pm, my phone vibrates with an incoming text message. I look down and see a photo of a frog taken in Hollywood. This isn’t an unusual occurrence. When you study urban biodiversity and spend big portions of time telling anyone that will listen that they can make the next big urban biodiversity discovery, this is the happy result—incoming photos of critters to identify. Usually it is a native frog, lizard, or snake, but with alarming and increasing frequency, the photographed critter is a nonnative species.

In this photo, the critter is a frog. But is it a common native or an unusual nonnative? Unfortunately, smartphones aren't great at taking nighttime photographs of frogs, and I can't yet be sure of the identification. However, I...

Arroyo #Chubwatch 2015

After three long years of planning, 45 arroyo chub were finally released into the Nature Garden's pond last week. 
Arroyo chub (it's alive, don't worry!) held for a quick photo op before release into the pond! Photo by Richard Hayden.

Arroyo chub, Gila orcuttii, are a native freshwater minnow found only in the coastal streams of Southern California, says Chris Thacker, Museum Curator of Ichthyology (fishes). They are classified as threatened in this native range and are noticeably missing from the lower reaches of the Los Angeles river. So, when it came time to think about fish in the Nature Gardens pond, all our scientists and educators wanted Arroyo chub.

The chub were transported from the...

First Lizard Found in Museum's Nature Gardens!

On November 19, 2014 something happened at work that I’ve been waiting three and half years for. Unfortunately, I wasn’t here to witness it, but thanks to citizen science I was able to celebrate the discovery, even though I was 6,187 miles away.

On that day, newly turned citizen scientist Toni Castillo documented the first lizard in the Museum’s Nature Gardens.

The lizard in question was a Western Fence Lizard, Sceleporus occidentalis, and Toni, a Museum staffer, just happened to see it as she was walking through the gardens.

“I was walking next to the Living Wall and saw something in the pathway. At first I thought it was a leaf or a stick, but then I looked closer and realized it was a lizard.”

Toni knew that this was a unique find—she’d heard...

Urban Foraging: Carp Caviar from the L.A. River!

Ask me where my favorite spot to explore urban nature is in Los Angeles, and I'll almost always say the river. This is particularly true during, and after, our seasonal rain storms. We're used to extreme heat episodes, wildlfires, and the odd earthquake* or two. But, by and large, us Angelenos are unaffected and unimpressed by the elements. Going down to the river after a good rain, you get a rare chance to see, hear, and feel the raw power of nature.

*Anyone else wake up abruptly last Monday morning after the 4.4 trembler, wondering how much water you could salvage from your toilet's holding tank?

During our most recent rain storms (February 28-March 2) I, along with a number of other people, ventured down...

Hawk Attacks Snake and Epically Fails!

Guest Blog by our very own Dr. Greg Pauly:

For local wildlife, living in the big city can be rough. Encounters with people and their dogs, cats, and cars all present threats not experienced by critters living outside of urban areas. Plus, these city dwellers still have to contend with many of the usual threats like predators and weather extremes. Here are two photos celebrating the scrappiness it takes to be a city dwelling reptile, and also celebrating the incredible opportunities to observe urban nature in action.

"David A." sent this photo to theeastsiderla.com of an adult San Diego Gopher Snake, Pituophis catenifer, schooling a juvenile Red-tailed Hawk, Buteo jamaicensis, near Elysian Park.

There are so many cool things going on in this photo. Cool factoid 1: Elysian Park!...

Lizards, Snakes, and Frogs Oh My!

This last Saturday we held the second annual Lizard Hunt at Malibu Creek State Park! Dr. Greg Pauly, Museum Herpetologist, and Dr. Bobby Espinoza, CSUN Herpetologist, took a group of 25 lucky people out to observe, catch, and identify local herps.

Are you looking at me?
