Great Egret stalks a lizard

Great Egrets are commonly seen wading along a shoreline, in marshes and wetlands waiting for fish to come near before catching them with a quick thrust of its bill.

Great Egrets primarily eat small fish.  However, their diet can also include reptiles such as lizards, amphibians, birds, small mammals, shrimp, worms, dragonflies, beetles, water bugs, and grasshoppers.

This particular Great Egret decided to stroll into the old campground at Alameda Point in search of food.  It walked slowly up to a Rosemary bush and stood there for about five minutes, occasionally making slight head movements, before plunging its head into the bush to catch a lizard.

After holding the lizard in its bill for a few minutes, it gulped down the lizard and proceeded very slowly to another bush.

City misses chance to embrace wetlands at Alameda Point

The city and its consultant recently released a report outlining what will be included in the new climate action plan for Alameda.  What it reveals, unfortunately, is their resistance to thinking big.

The process for updating Alameda’s climate action plan began as a promising effort for a comprehensive look at what it means to adapt our entire environment to climate change.  It is winding up with a narrow focus on protecting local real estate, which they refer to as “vulnerable assets.”

The city has rejected a broader scope of action that would include “opportunity assets,” as in opportunities to improve the natural environment, not just the built environment.  Areas at Alameda Point not slated for development must be viewed as an opportunity asset that can be re-purposed for the good of the environment.

Navy to create new wetlands

The Navy is nearing completion of plans for a cleanup area called Site 32, 60 acres that lie on the old airfield west of where the monthly Antiques Faire is held.  The site requires remediation because investigators discovered radium-226 in the soil and on various objects.  The Navy mixed radium-226, a naturally occurring mineral, with paint to allow dials and markers to glow in the dark.  Repeated exposure to high levels of radium can cause cancer.

The Navy collected radium-impacted waste, such as used paint brushes from refurbishing dials and gauges, scraping solids, and rags, from its dial painting shop on a regular basis and discarded it at the Site 1 underground dump adjacent to Site 32.  The Navy presumes that the radium-impacted items were spread beyond the dump site when the runway was expanded in the 1950s and a bulldozer was used to grade the area above the dump.

BART station may come to Alameda Point

Bay Area Rapid Transit (BART) staff are in the early stages of planning for a second tube across San Francisco Bay.  One of the routes being considered is under Alameda and would bring with it at least one station.  It could also bring Amtrak’s Capitol Corridor train service running in tandem with BART trains across the Bay.

Before any plans are drafted, the transit agency must first determine the amount of ridership the transit system will serve in the decades ahead.  To get there, BART is looking at more than just the traditional 9-county region.  They are looking at projected transit needs of a 21-county mega-region stretching from Placerville to Monterey.  And standard-gauge rail agencies, like Amtrak, have become a partner in BART’s planning effort.

Urban Shield conducts hostage rescue training on Nature Reserve

On Sept. 9, the tranquility of the remote shoreline on the federal property at Alameda Point was interrupted by participants firing blanks as an Urban Shield police tactical team staged a mock hostage rescue.  The gunfire was part of the emergency preparedness training that was performed in an area the U.S. Department of Veterans Affairs (VA) agreed not to use for this purpose.

Osprey Family Thrives in Face of Adversity

Ospreys returned again this year to nest at Alameda Point’s Seaplane Lagoon.  But midway through the rearing process, the female became the sole provider and protector of her three chicks, after the male became entangled in fishing line.  Such osprey single parenting is unheard of.
