On Memorial Day Weekend (Sat. 5/23), Come and Help Stewarding the Oaks of Lakeside Park

Recently, we were saddened by the loss of one of Lakeside Park’s most remarkable Coast Live Oaks near the Bandstand—possibly among the oldest and certainly one of the largest in the Park. Its canopy once stretched nearly 50 feet in diameter, supported by an extraordinary branching structure, but in recent years, more than 90% of its evergreen foliage had disappeared.

Back in December 2024, before the Conservancy had formally received 501(c)(3) status, we first observed severe canopy decline in this tree and in several Cork Oaks along Bellevue Avenue. These inspired the creation of our tree care stewardship initiative in summer 2025, with strong support from Oakland Public Works.

Unfortunately, this past winter, mushrooms and cankers associated with heart rot and structural weaknesses were discovered growing at the base and within the trunk of the tree, and it was ultimately determined to be beyond saving and a safety concern.

This Memorial Day weekend, we hope you will join us again in supporting the health and resilience of Lakeside Park’s remaining California native oaks—arguably the most important keystone tree species in the region's ecosystem.

We will gather at the Snack Shack patio, uphill from the Bandstand, on Saturday, May 23rd, from 9:00 AM to 12:00 PM. As many of you know from past stewardship days, volunteers will help remove some invasive weeds and apply sheet mulch around the trees out to the drip line. One of the trees we will focus on this month is another at-risk Coast Live Oak worthy of heritage tree recognition.

Together, the day’s work will help improve habitat conditions for wildlife, strengthen soil health for the vulnerable trees, and create a visible ecological improvement at one of the symbolic heart spaces of the Park.

Consider joining us—even for part of the morning—RSVP (jason@lakemc.org) by Thursday, May 21st. Lakeside Park’s trees, and the future resilience of Oakland’s urban forest, depend greatly on community stewardship efforts like yours.
