This past Saturday a team of hard-working volunteers removed two species of invasive trees that were sprouting up in the Foothill Blvd parkway – Ailanthus altissima (Tree-of-Heaven) and Melia azedarach (Chinaberry). Both of these fast-growing Asian Trees resprout from stumps or root fragments, so the volunteers had to dig up the roots.

The volunteers completely removed all the invasive trees from two areas – one to the east of the entry gate…
…and one to the west.
While working in the parkway, the volunteers also trimmed up some of the Coast Live Oaks (Quercus agrifolia) and European Olives (Olea europaea) where there was evidence of camping under the tree canopies.

And last, the volunteers picked up trash in the parkway – plastic bags, papers, fast food cups, an old yoga mat, and even a political campaign sign.
Of course, we also noticed some interesting flora and fauna. Ben Stapp found a burl from an olive tree…
…and his dad, Prof. Paul Stapp, uncovered a Jerusalem Cricket (Stenopelmatus sp.) while digging.
Thanks to all the volunteers, who did a terrific job! Everyone is welcome to join us on the first and third Saturdays for most months – you can check the schedule here.
