We lost 23 trees last week. They were saplings, planted only months ago. They were yew pines, chinese fringes. Their holes were dug by more than one hundred volunteers and led by AmeriCorps members. They were bought with money provided by San Jose, by Councilman Pierluigi Oliverio. They were grown in our nursery, tended to by our volunteers, by school groups and dedicated AmeriCorps members. These trees took time, effort and cooperation to raise. They took money, community investment and muscle to put into the ground. They took dedication to tend on our weekly watering runs. In a way, these trees were representations of us, as a community. If they had been allowed to continue growing they would have provided shade, flowers and air-cleaning to a hot and busy street.

In their natural state riparian corridors are rich in vegetation and wildlife. A presentation by the the Santa Clara Water District states that “native plants are ecologically best suited to the creek environment.” Plants and wildlife benefit from the sediment and organic material that streams transport and deposits on their banks. In this way, soil is enriched, erosion offset, and aquifers replenished. Native plants and aquatic life are adapted to seasonal variances in river flow, including annual flooding. As F. Thomas Griggs writes, “Cottonwood and willows, as well as all other riparian plant species, are directly dependent on patterns of sediment erosion and deposition.”
Our City Forest is a nonprofit organization dedicated to cultivating a green and healthy Silicon Valley by engaging the community in the protection, growth and maintenance of our urban ecosystem, with special focus on our urban forest.
‘Epiphyte’(“epi” = on top of; “phyte”= plant in Greek), is a fancy-sounding term for a plant that spends most or all of its life living on another plant, usually on a tree . You might think that an epiphyte is a parasitic plant, but it is not! These plants only use the tree as a support system and take no nutrients from the tree itself. They instead rely on rainwater to carry nutrients down tree bark or on collections of soil and detritus in the crotches of branches. Epiphytic plants are represented throughout the plant kingdom, including non-vascular plants (mosses, liverworts, hornworts) and vascular plants (plants that can conduct water).
We here at Our City Forest love talking to local residents, neighbors and random passers-by when we’re serving the communities of the Silicon Valley. We get asked a lot of questions about who we are and what we do. In general these interactions are friendly but sometimes, when the hoses are running and the water buckets are filling we get asked:
