North American Butterfly Association Count


A North American Butterfly Association (NABA) Count will be on April 11, 2020 (weather permitting).
The count is centered at Salt Creek Recreational Center in Chula Vista (near Otay Lakes).
With an 8-mile radius, this area includes R. Jamul, SD National Wildlife Refuge (R. San Diego),
Sweetwater Reservoir, Sweetwater Regional Park, and Otay Region.

You can find this count on:


under: "Southwest San Diego County, CA"

If you or any of your friends are interested, please let me know by the end of March. Also, your level of expertise with butterflies so I can match experts with novices. No nets will be used,
just binoculars and lenses. This is the first time that a NABA count has been conducted in San Diego city limits in
a while (if ever), so it should be fun.
We will be meeting at Salt Creek Recreation Center in Chula Vista at 9am. All levels welcome from beginner to expert!

Scientists look to public to help migratory monarch butterflies bounce back.

During the Western Monarch Mystery Challenge, which starts on Feb. 14, Valentine’s Day, and runs through April 22, Earth Day, California residents are asked to report sightings of monarchs. The data they collect will give much-needed insight into the butterflies’ habitat needs during the spring months, so researchers can better target conservation efforts.

With No Sign of Monarch Rebound, Butterfly Experts and Enthusiasts Meet and Plan.

The monarch butterfly population on the West Coast has been trending downward since the 1980s, but early in 2019 the insects really made the news when numbers from annual Thanksgiving and New Year’s counts dropped below 30,000, the point at which scientists say the butterflies might not be able to recover.

Will Monarch Butterflies Bounce Back?

This weekend, a hundred and sixty monarch butterfly experts and enthusiasts from all over the country met in Carmel for the first-ever Western Monarch Summit, to discuss the “state of the western monarch.” The species numbers’ have been on a downward trend since the ‘80s but last winter, monarchs in California made the news because they had a really steep decline in their population, dropping to such low numbers that scientists warned they could go extinct. Everyone has been holding their breath to hear what the numbers are this year. There is good news and bad news.
