It’s officially Spooky season 🎃, so that means it's time for a spooky edition of Winged Wednesday! 🦇

This week’s feature is the Townsend’s Big-eared Bat! These unique bats can be found all along the Pacific coast, from Mexico to Canada! Oak woodlands offer a perfect habitat for foraging and dark roosting coverage. 🧛

Despite their impressively large ears, these little guys have a body length of just 9-11 cm!! Not only that, but they are completely nocturnal, so you’d need night vision to see them in action! 👀

Good luck trying to find the Townsend’s Big-eared bat this Spooky Season!

In total, it encompasses three elements: community engagement opportunities, an Existing Conditions Report, and the final product, the Trails Master Plan.

We’re toad-ally🐸 hyped for this Field Friday because we are featuring the California Toad!

California toads are habitat generalists - they can thrive in a wide range of environmental conditions🌼🌱. That means you can find them in all kinds of communities! They are also omnivores, and they switch from eating prey🪰to eating plants🍄depending on what the habitat has to offer.

Fun fact‼️: instead of long hops, California toads prefer a slow and steady crawl or walk!

If you think you’ve stumbled upon one, check if it has a light colored strip that runs down its spine. If it does, you’ve likely found a California toad🐸! Snap a picture and post it on iNaturalist!

It’s election season, and here’s why you should vote NO on Prop 45!

Prop 45 aims to modify environmental review for certain projects, meaning CEQA could be completely bypassed.

CEQA requires developers to consider the environmental impacts of their developments, and do their part in mitigating them. It also gives the public a say in the projects being proposed in their own communities.

It’s true, Prop 45 would speed up particular development timelines, but it would also shift the power to project developers. It could completely eliminate environmental considerations and YOUR say on certain infrastructure changes in your community.

A NO vote on Prop 45 protects air, water, and environmental quality, public health, and YOUR voice!

We’re 🕷️dying🕷️ to feature the California Ebony Tarantula for this extra spooky edition of Field Friday! 👻🎃

These native spiders live in ground burrows in grassy areas, coastal sage scrub, and chaparral habitats around Southern California and Baja California, Mexico. Like many other creepy-crawlies, they’re nocturnal, 🌙 so our fellows were lucky to spot this one during the day at Mission Trails Regional Park! 🕷️It’s the start of their mating season, when males will start to venture out from their burrows during daylight in search of a lady spider.🍂

Though with a legspan of 5 inches they may look scary, these spiders are reclusive and non-aggressive. They use fangs to prey on soft-bodied insects like crickets, 🦗 cockroaches, 🪳 and worms, 🪱 but rarely ever bite humans.

🕸️Their “hair” is made of chitin, the same material as their exoskeleton, and helps deliver sensory information like movement, vibrations, and even smells! 🕸️

Ready for a glow up? ✨💅

Some people say San Diego has no seasons because of our stable Mediterranean climate. But it isn't all sunshine! Our year is split into a hot dry season that starts around May,☀️ and a cooler wet season, starting around November. 🌧️

Many of our native plants go dormant to save water during the dry season. They might look dead, but they're just getting their beauty sleep! 😴 They'll spring back to life once more resources are available in the wet season, growing taller, turning green, and even flowering! 🌸🌱🌼

The upcoming El Niño event is predicted to bring a particularly wet winter to San Diego. Meaning these plants and more are about to get a major glow up! Swipe right👆📲 to see which ones and learn more! 🌿
