City of Los Angeles Approved Street Tree ListKeyEvergreen, Deciduous, Semi-deciduousE - Evergreen. The tree has leaves year-round.D - Deciduous. All leaves lost in one season.S - Semi-deciduous. Most, but not all leaves lost.Spacing: Distance from tree to tree, measuredfrom center of trunk to the next trunk center.YELLOW HIGHLIGHTED TREES:These trees are reproductive hosts (the beetle can reproduce inside the tree) of the Polyphagous Shot HoleBorer (PSHB). PSHB is a very small beetle that bores into trees and infects them with a fungus (Fusarium). TheFusarium clogs the cells of the tree, thus blocking the flow of water and nutrients and kills the tree. Because thebeetle attacks many tree species (and more are being added to the list every month), we are advising not toplant the tree species that can harbor these pests. Work is being done by the University of California to findnatural controls. Shot Hole Borer/Sunset Climate Zone - From the Sunset Western Garden Book . Zone 24 is the immediate coast, zones 21 - 23 are the L.A. Basin, zones 18 - 20 are the Valley.Sun: S full sun; P part sun/part shade; Sh shadeWater: Ratings from WUCOLS IV (Water Use Classification of Landscape Species Search/)LA Basin Sunset Climate Zones 22-24; Valley/Inland Sunset Climate Zones 18-21VL - Very low. Trees should not need water other than natural rainfall. Prolonged drought may require a deep watering once or twice if severe wilting is exhibited.L - Low. One deep watering per summer month, or every other month in dry season if needed.M - Moderate. Two deep waterings per summer month. Perhaps one deep watering in spring and fall.H - High. One deep watering per week in summer months. One deep watering every other dry season month.VH - Very High. The soil needs to be kept moist. These trees naturally occur in riparian zones - stream or lake-side.Soil: C Clay; L Loam; S Sand; WD Well drainedParkway Size (Growing area measureed from curb to sidewalk). This minimum is up to the discretion of the city's street tree inspector.Root Damage Potential - These ratings obtained from the Cal Poly Web site: L Low; M Moderate; H HighAllergy Potential - These ratings (1 - 10) from Thomas Ogren's OPALS (Ogrens Plant Allergy Scale) System in Allergy Free Gardening .The increasing incidence of asthma and allergies in the Los Angeles area has prompted us to include this information. Some trees are now outlawed on school campuses because of theirhigh allergy potential. In the flower, it is the male anther that produces pollen, the biggest allergy issue. Most flowers are complete, meaning they have both male and female parts. Somespecies, however, have flowers that are only male or female. These species have either separate male oand female trees (dioecious - two houses), or they have those male-only andfemale-only flowers growing on the same tree (monoecious - one house, like corn), and yet others have separate male and female flowers and also some bisexual flowers. Over the years,male trees have been chosen for street trees and for campuses to avoid the mess of fruit drop from female trees. This has resulted in an increase in male tres, and therefore an increasein pollen.1 lowest rating, least allergenic pollen. If separate male and female trees, these will be the female trees.10 highest rating. These trees are usually wind-pollinated or have very fine pollen grains. If separate male and female trees, these will be the males.f female; m male; b bisexual, having both male and female flowersGrowth Rate: S Slow - up to 12"/year; M Moderate - 24"/year; F Fast - 36"/year; VF Very fast - more than 36"/yearBiogenic Emissions: Some trees emit chemicals that mix with nitrous oxides and create ozone (a main ingredient in smog).
