A color photo showing a landscape in dense morning fog. Ridges covered with low-growing shrubs recede into the distance. Coniferous trees accent the ridges.

The "radicle" is the first root to emerge from a germinating acorn. It penetrates the soil, pulls in nutrients and anchors the seedling. #oaks #trees

Englemann oaks are classified as threatened because of habitat loss. Restoring Englemanns, which are native to just a small section of Southern California and northern Baja, is part of The Oak Project’s focus. Seedlings being raised in pots now will be ready for distribution in early 2026. #oaks

Another successful harvest on the outskirts of Jamul on Monday yielded hundreds of Englemann and scrub oak acorns. Thousands of seedlings from multiple oak species should be ready for distribution by the spring. #trees #oaks

When people think “fall colors,” San Diego County usually doesn’t come to mind. But there’s color to be found if you know where to look. These poplars were popping Wednesday near Lake Cuyamaca. Black oaks in the county mountains turn a vibrant yellow, & they should peak in early November. #trees

While the San Diego County valleys roasted again today, it was gorgeous in the mountains. Mid to upper 70s with an occasional light breeze in the Cuyamacas on and near Middle Peak. Excellent hiking weather. Black oaks appear maybe a week or two from peak fall color. #sandiegoweather #CAwx

A big coast live oak can produce thousands of acorns a year. In bountiful "mast" years, they can grow 10,000. Oak Project founder Jim Crouch says it appears many So Cal oaks shed acorns early this year, perhaps due to a lack of winter rain. Pictured is a huge tree near Lake Hodges. #trees #oaks

The floss silk tree (Ceiba speciosa) dresses up for Halloween with big, beautiful blooms - and spikes on its branches. It's a native of the tropical and subtropical forests of South America, but many floss silks thrive in San Diego County. This one is in Escondido. #trees

Atop cracked gray stone cliffs under a mostly cloudy sky with thin hazy clouds and patches of deep blue. To the left is a pine tree, To the right and below is a forest of mostly hardwoods and a sprinkling of cedars. A mostly wooded valley hundreds of feet below with glimpses of many houses and other buildings rolls downward towards the city of New Haven on the horizon with Long Island Sound and Long Island just visible as streaks of gray beyond. The forests along our cliff and the peak across the valley sport foliage of oranges and golds, with a scattering of deep green evergreens for contrast.

More than 180 people helped launch TSD's Plant-A-Thon in National City Oct. 10, when we planted 100 trees. Help us reach our goal of 1,000 trees in the county by Dec. 31. Contact [email protected] to bring your team to a planting, or aid the cause with a donation to Tree San Diego. #trees

The Los Peñasquitos Canyon Preserve is home to some fine groves of coast live oaks (Quercus agrifolia). One of the many reasons The Oak Project aims to restore oaks in Southern California is the habitat the trees provide for countless bird, animal and insect species. #trees #oaks

Connections are sprouting! Donors in Pine Hills, Wynola, Sutherland Lake & Volcan Mountain have offered acorns for The Oak Project's propagation efforts. Along with a growing crop of financial supporters, the goal of raising 20,000 seedlings for distribution in 2026 looks doable. #oaks #trees

TSD's next Tree Treks is Saturday at La Mesita Park in La Mesa from 10 to 11:30 a.m. Join us for a guided walk where you can learn about the diverse tree species in your neighborhood, how to identify them & the role they play in creating a healthier, cooler, more climate-resilient community. #trees

Put to the test: One of the ways to check if an acorn is a good candidate for propagation is the float test. When placed in water, more viable acorns will sink. Those that float have air pockets and are likely to have been damaged by insects like weevils. Discard floaters, keep sinkers. #oaks #trees
