Last Friday, three school buses motored up into the Oakland Hills with 140 ninth graders from Oakland Tech High School. These students joined us to visit Chabot Space & Science Center and explore the coast redwood forest just beyond.
Despite the morning rainfall, these students worked with League Education Manager, Deborah Zierten, to measure the size of redwoods at Redwood Peak. They used tape measures to document the trunk diameters in this second-growth forest and estimate tree heights. They contemplated what factors in the environment influence redwood growth and wondered how recent drought will impact the forest.

They also joined me to Fern Watch – measure the height of the most common plant on the coast redwood forest floor, sword fern. They counted fronds, checked for leaf munching by pesky caterpillars, and marveled at how the sword ferns 200 miles north along the coast grow twice as tall.
Many of these students lived their entire lives in Oakland and yet had never traveled to this vibrant forest only a few miles from their urban homes. It was a privilege to guide these students through their first redwood field trip, let’s do it again!
