For the coming week, we will hold our regular work parties, with updated hours from 5:00–7:00 pm to enjoy cooler temperatures, a pleasant evening atmosphere, and to make it easier for those coming after work.

Sunday – Hike Work Party
A light hiking work party removing invasive plants along the way. We will alternate between early weed management of crofton weed (which rebounded after winter rains and recent heat), removing scattered French broom, or tackling larger broom removal in the middle meadow depending on turnout and interest.
Meet at the start of Regency Court (1531 Regency Court).

Below is a photo of crofton weed, a particularly aggressive invasive species.

Crofton weed (Ageratina adenophora) is considered a particularly problematic invasive for several reasons:

• Fast spread: It produces large quantities of wind-dispersed seeds, allowing it to colonize new areas quickly.

• Dense stands: It forms thick monocultures that outcompete native plants for light, water, and nutrients.

• Allelopathy: It releases chemicals into the soil that can inhibit the growth of other species, giving it an additional advantage.

• Lack of predators: In California, it has few natural enemies, so nothing keeps it in check.

• Ecosystem impact: It reduces biodiversity, alters habitat structure, and can degrade areas that support native wildlife.

• Toxicity: It is toxic to livestock and can affect soil health over time.

Because of these traits, even small infestations can expand rapidly if not managed early.
