October 20th, 2018: Mulching the oak trees at the Stanley Reach

Thirty six volunteers helped us spread mulch around our oak trees and weeded 360 gallons of stinkwort (Dittrichia graveolens) from the Stanley Reach today, thank you! We also celebrated the season with costumes and a scavenger hunt for pumpkins! Mulching is a great way to build soil by introducing organic matter and beneficial organism to the soil; it also suppresses weeds that would shade our oak trees and compete for water and nutrients.

Stinkwort (Dittrichia graveolens) is an incredibly voracious weed, the article at UC Davis explains the expanding range of this invasive species. Stinkwort loves to grow in areas that have been disturbed by human development and will quickly take over an area, crowding out the native species that are trying to gain a foothold. Invasive species often do not have predators that eat them or pathogens that plague them, it is up to us to control their population.

October 6th, 2018 Touriga Creek Clean-up

10..6.18 Touriga Creek (3)

Fifteen volunteers helped us clean Touriga Creek on October 6th 2018. We removed 61 gallons of trash and 21 gallons of recyclables, great job! This work prevents plastic debris from washing downstream into the San Francisco Bay. Plastic waste in our oceans is becoming a serious problem but we can work together to be better stewards of our local watershed and of the Earth.

Thank you!

The seventh annual Creeks to Bay Clean-up was coordinated by the Adopt a Creek Spot program and is part of a worldwide Coastal Clean-up Day that occurs annually. The work we do to remove trash in our urban streams before it reaches the ocean helps to save the lives of countless marine organisms! 257 volunteers and staff helped to remove a total of 2,112 gallons of trash and 264 gallons of recyclables from eight different spots along the Arroyo Mocho and the Arroyo Las Positas in Livermore California.
