We Need Acorns!

From little acorns, mighty oaks do grow, so if you have a fruitful oak tree in your yard of neighborhood, please collect a bag of acorns for us. Put the acorns with a leaf-bearing twig for the tree in your frig and shoot Watershed Coordinator Jonathan an email at jonathan@arroyoseco.org so we can pick up the acorns for use in our nursery. We are particularly interested in acorns for the stately Engelmann oak trees which are rare and threatened.

Hahamongna Remains the Focus

It's the most precious enviromental zone in our region, but it's under attack again. There's no question about it: your continued vigilance is needed to keep Hahamongna natural.

	A massive sediment removal program of the County of Los Angeles threatens to strip the basin of its rare habitat
	Pasadena is forging ahead with an ill-conceived plan to add a parking lot and a soccer field to the center of the basin.

We urge you to become informed about the issues and to get active to save this environmental treasure.

The Chub Are Back in the Arroyo

The Arroyo Chub, a native species that once thrived in the Arroyo Seco, has returned. Last summer three hundred of the small fish were planted in the natural stream areas of Pasadena's Central Arroyoo stream below Devil's Gate Dam and just above the Colorado Street Bridge, and recent sightings indicate the fish are doing well particularly in the lower stretch.

"This is a momentous development and a key milestone in our campaign to restore the natural attributes and functions of the Arroyo Seco," said Tim Brick, Managing Director of the Arroyo Seco Foundation. The fish restoration came as part of the Central Arroyo Stream Restoration Program completed by ASF and the City of Pasadena. The project included water quality islands in Brookside Park parking lot, trail improvements, and backwater pools and improved habitat for the fish.
