The Athens-Clarke County Tree Species List The Athens-Clarke County Tree Species List is intended to support the development code, site planning and design activities for tree conservation and establishment, and tree maintenance planning and decision-making. In the list trees are arranged alphabetically by the tree’s common name with the “genus” listed first. For example, red maple is listed as “Maple, Red” (maple is the genus name). The Latin name is also listed for more definitive species identification. In some cases, the commonly planted variety or cultivar of the species has also been included apart from the species. Key to Symbols and Tree Species Characteristic Descriptions TREE CHARACTERISTIC DESCRIPTION and ENTRY CHOICES Species Common Name Entered with genus common name first, then species, then cultivar if applicable. For some species an alternate common name is included in parentheses. Latin Name Genus, species, and variety or cultivar; always italicized or underlined. CANOPY AREA FOR DEVELOPMENT CODE Square Feet of Canopy The total area projection of the crown onto the ground in square feet as typically achieved in urban situations with less than optimal growing conditions. Canopy Size Category VS = Very Small - 150 square feet with a 15 foot crown diameter The minimum open soil surface area is 25 sq. ft. S = Small – 400 square feet with a 25 foot crown diameter The minimum open soil surface area is 100 sq. ft. M = Medium – 900 square feet with a 35 foot crown diameter The minimum open soil surface area is 225 sq. ft. L = Large – 1,600 square feet with a 45 foot crown diameter The minimum open soil surface area is 400 sq. ft. RECOMMENDED USES Level of Use The level of use that the tree should receive. NewC = Plant New Trees and Conserve Existing Trees Cnsv = Conserve Existing Trees (not recommended for new installs) Limit = For Limited Planting or Conservation Only NoPlnt = Do Not Plant Large Landscape Areas Road Frontages – Street Road Frontages – Yard Parking Lots Plazas and Downtown Settings Riparian Zones and Drainage Areas Utility Corridors Recommendations on the site situation where the tree may be planted and/or conserved; locations where the tree would adapt well. X = tree to avoid; not suitable Blank = may or may not be suitable good choice excellent choice Tree is Commonly Utilized X = tree to avoid; not suitable Limit = Utilized very much (potential for overuse – Limit Use) Blank = may or may not be suitable good choice (tends to be successful and not over utilized) excellent choice (provides multiple benefits and is fairly rare) Revised 2/25/2020 1 ---PAGE BREAK--- TREE CHARACTERISTIC DESCRIPTION and ENTRY CHOICES PHYSICAL CHARACTERISTICS Height Class in Urban Conditions Height class (ground to tip of leader or tallest branch) of a mature tree commonly achieved in urban situations with less than optimal growing conditions. S = Small: 15-25 feet M = Medium: 25-40 feet L = Large: 40 feet and taller Crown Class in Urban Conditions The width of the crown (at its widest point) commonly achieved in urban situations with less than optimal growing conditions. VS = Very Small (150 square feet with a 15 foot crown diameter) S = Small (400 square feet with a 25 foot crown diameter) M = Medium (900 square feet with a 35 foot crown diameter) L = Large (1,600 square feet with a 45 foot crown diameter) Mature Crown Form General shape of the tree crown (leaves and branches) when fully leafed out. Irregular Multi-Stemmed Oval (Columnar) Pyramidal Rounded Spreading Upright (Vase) Typical Range of Mature Tree Height Typical range of height of tree in feet from ground to bud at tip of leader or tallest branch under various conditions. Typical Range of Mature Crown Width Typical range of spread of branches in feet at the widest diameter across the crown under various conditions. Leaf Type Persistence and type of leaf on the tree. Deciduous trees lose their leaves in the fall. DB = Deciduous Broadleaf DC = Deciduous Conifer EB = Evergreen Broadleaf EC = Evergreen Conifer Leaf Texture Relative size and appearance of leaves. F = Fine M = Medium C = Coarse Fall Leaf Color The typical color of the tree's fall foliage. EV = evergreen BR = bronze or brown MA = maroon MU = multi-colored: maroon, red, orange, yellow OR = orange RE = red YE = yellow I = insignificant color change Revised 2/25/2020 2 ---PAGE BREAK--- TREE CHARACTERISTIC DESCRIPTION and ENTRY CHOICES PHYSICAL CHARACTERISTICS (continued) Flower Color For trees with showy flowers, indicates the typical flower color. B = blue L = purple M = multiple colors: white, pink, purple, red, or others P = pink R = red W = white Y = yellow I = insignificant flowers: small with an unremarkable color Flowering Time For trees with showy flowers, the general season of blooming for the species. Wildlife Value Indicates with an if the tree produces flowers (nectar) or fruits that are consumed by insects, birds, or mammals. Excessive Litter Indicates with an " X " if the tree produces large or hazardous leaves, fruit, or other litter. ENVIRONMENTAL CHARACTERISTICS AND TOLERANCES Native Tree to Athens- Clarke Co. Indicates whether or not the tree is found naturally growing in the Athens-Clarke County area. Y = Yes N = No Growth Rate Typical rate of growth under urban conditions. S = Slow: 1/2 to 1-1/2 feet/year M = Moderate: 1-1/2 to 2-1/2 feet/year F = Fast: 2-1/2 to 3+ feet/year Average Life Span The average life span (useful service life) of the species when growing under average urban conditions. A tree is at the end of its useful service life when its risk of failure becomes unacceptable and cannot be improved or when the tree is no longer an asset due to its appearance or condition. S = Short: less than 25 years useful service life. M = Moderate: 25 to 40 years useful service life. L = Large: 50 years or greater useful service life. Net Effect on Air Quality The net monetary effects in cents attributable to the species on air quality; listed as a benefit (positive) or cost (negative). Includes the species net effect on ozone, sulfur dioxide, nitrogen dioxide, particulate matter (PM10), and carbon monoxide. Soil Moisture The typical soil moisture conditions for the species in its native habitat. H = Hydric: wet and may be occasionally flooded for short periods M = Mesic: moist but moderately well- to well-drained X = Xeric: dry and very well-drained Revised 2/25/2020 3 ---PAGE BREAK--- TREE CHARACTERISTIC DESCRIPTION and ENTRY CHOICES ENVIRONMENTAL CHARACTERISTICS AND TOLERANCES (continued) Drought Tolerance Tolerance of the species to infrequent rain, low soil moisture, full sun, and high temperatures. Low = not tolerant to drought conditions Moderate = tolerant to mild drought conditions; moderately tolerant to severe drought conditions High = very tolerant to mild to severe and prolonged drought conditions Preferred Soil pH Relative soil acidity or alkalinity preferred by the species. In many cases, a range of pH preference is given if it was available. In other cases, a general level is given. A pH of 7.0 is neutral, a pH of less than 7.0 is acidic, and a pH of greater than 7.0 is alkaline. ac = acidic (5.0 to 6.0) sl ac = acidic (6.0 to 7.0) nu = neutral (7.0) sl al = sl alkaline (7.0 to 8.0) al = alkaline (8.0 to 8.5) n/a = no information available Light Requirement The amount of sunlight the species prefers or will tolerate. Trees that are typically found in the understory or are characteristic of late forest successional stages prefer shade or at least partial shade, while trees that typically form the overstory or are characteristic of early successional stages prefer full sun. FS = Full Sun PS = Partial Shade SH = Shade Construction Tolerance/Limitations The broad tolerance of the species in its home range to construction damage, and the limitations that constrain a species tolerance to damage. Tolerance P = Poor M = Moderate G = Good Limitations Susceptible to I = physical injury, wood compartmentalization and decay P = pest complications, including chronic and acute attacks S = soil conditions, including aeration and water availability C = limited climatic tolerances, including native range, hardiness, and micro-climate change X = all of the limitations described above Urban Tolerant Tree Based upon other characteristics and tolerances to urban conditions; an indicates the species is suitable for planting under “tough” urban conditions.
