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

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

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

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

Going green & thinking big: TSD kicks off "Plant-A-Thon" Friday at El Toyon Park in National City at 10 a.m. We'll plant 100 trees & aim to plant 1,000 across San Diego County over the next 10 weeks to celebrate our 11th anniversary. (Previous post had date right but day wrong; it's Friday) #trees

There is a tree in Nashville that I'm pretty sure was pulled up into a tornado when it was a sapling, but it had strong roots and it survived. I visit it every time I'm at Centennial Park. When I first moved here, it was barely taller than me, and now it's an adult!

A trip to Pala Thursday yielded 516 viable acorns for propagation. Much thanks to Phil, one of The Oak Project’s biggest donors and supporters. The acorns were from coast live oaks (Quercus agrifolia); scrub oaks (pictured, Quercus berberidifolia); and Englemanns (Quercus engelmanni). #oaks #trees
