4 STANDARD 2: Campus Tree Care Plan 1. PURPOSE Clayton State University is dedicated to caring for the campus tree population by providing a safe, healthy and sustainable environment for the trees and the overall campus. The Landscape Management department continuously works to maintain, manage, improve, renew and protect the trees on the University s campus. Through careful planning and proper maintenance, the trees of Clayton State University will enhance the University s landscape, provide a habitat for a diverse animal and insect population, and provide a pleasant environment for study for many generations to come. The University commits to: Maintain a diverse landscape with a wide range of tree species Provide various habitats for enjoyment and study on campus Maintain a park like setting for students Provide homes to tree dwelling insects and animals Continue to care for and maintain all trees so that future generations will be able to enjoy their benefits 2. RESPONSIBLE AUTHORITY/DEPARTMENT The Clayton State University Landscape Management Department and the Campus Tree Advisory Committee is responsible for the Campus Tree Care Plan 3. ESTABLISHMENT OF CAMPUS TREE ADVISORY COMMITTEE The Campus Tree Committee services as an advisory committee and shall be responsible for helping to update this plan in conjunction with the Facilities Landscape Management department. 4. CAMPUS TREE CARE POLICIES Clayton State University has a large and diverse tree population that varies in both species and age. The health of this population is maintained by following regular policies and procedures Clayton State University 4

5 I. TREE ASSESSMENT: II. TREE REMOVALS: III. TREE SELECTION: IV. SITE PREPARATION: Trees are constantly monitored for safety, pests, disease, maintenance, other environmental factors and the overall health of each tree. Trees are removed when they pose a safety hazard, become structurally weak, become invasive or compete with desired species. Each tree shall be selected for the proposed site by reviewing or increasing the needs of the site and the character sites of the tree and the optimum growing environment. Soils shall be checked for compaction. If soils are compacted, mechanical implements and amendments shall be used to improve soil structure. V. TREE PLANTING Trees shall be planted in the fall and winter months (or in dormancy stage). Although the tops of trees may be dormant, the roots will continue to grow allowing for establishment. When planting an individual tree or shrub in native soil that has not been disturbed or amended, dig the planting hole at least two times wider than the root ball of the plant. The depth of the hole shall be no deeper than the size of the root ball. It is best to plant 1 to 2 inches above grade to allow for soil settling and mulching. Always backfill with native soil that was removed from the hole. VI. MULCHING VII. PRUNING All newly planted trees shall receive 3 to 5 inches of mulch after initial planting, keeping the mulch 6 inches from the base of the trunk. The recommended mulch should be organic and aged mulch, and should be non-matting. Examples would include hardwood, cypress, and pine bark mini-nuggets. Avoid using pine straw as base mulch, because pine straw does not absorb as much moisture as hardwood mulch. Trees shall be pruned for safety, proper form and visibility issues. VIII. WATERING Trees shall receive at least 1 of water per week during the first growing season or until a healthy root system is established. The following trees are prohibited for new plantings due to their invasiveness, weak structure and safety hazard issues. Prohibited Species: Sweetgum (Liquidambar styraciflua) Pines (Pinus spp.) Empress Tree (Paulownia tomentosa) Chinaberry (Melia azedarach) Bradford Pear (Pyrus calleryana Bradford ) Black Locust (Robinia pseudocacia) Tree of Heaven (Ailanthus altissima) Mimosa (Albizia julibrissin) 2013 Clayton State University 5

7 5. PROTECTION AND PRESERVATION POLICIES AND PROCEDURES In order to protect and preserve trees during construction, policies must be followed to protect their trunks and root systems from construction site injury. The root zone of all trees must be protected on all construction projects. A tree s root zone is defined as 5 times the trunk diameter distance from the base of the trunk, or from the trunk to the tree drip line, whichever is greater. Ten feet beyond the drip line is preferable. All trees to remain on a project shall have protective fencing. A tree protection drawing detailing the protective fencing shall be submitted with the project plans for review. The drawing should include an accurate representation of the existing trees to remain, to be removed, and to be relocated, including species, trunk diameter and canopy diameter. Protective fencing should be placed at 10 beyond the tree drip line wherever possible. Construction materials, equipment and personal vehicles should not be stored or parked in the root zone of any trees in order to avoid soil compaction. Overhanging tree canopies will be protected from construction damage. All trenching shall conform to the following guidelines: Roots larger than 2 inches in diameter should not be severed without approval. Boring under roots rather than cutting is preferred. Digging within a tree s root zone should be avoided. If it is necessary, hand digging should be used for any trenching within the tree s root zone. All roots that must be cut should be cut cleanly. All planning, construction, and renovation projects on campus should at minimum preserve the existing tree canopy cover and species represented. 6. GOALS & TARGETS Bartlett Tree Experts was retained to perform a tree inventory for Clayton State University. The inventory included: Identifying trees on the Clayton State University property and assigning a tag number to each tree. Identifying the trees condition, health, and vigor. Recommending hazard evaluations and removals of appropriate trees. Recommending pruning, soil management, and pest management treatments to promote tree safety, health, and longevity. Mapping the trees using Global Positioning Satellite Receiver (GPSr) hardware and Geographic Information System (GIS) software Clayton State University 7

8 Clayton State University has a Certified Arborist on staff to evaluate the tree inventory on campus. The goals are to plant more long-lived specimen trees that students, staff, faculty and visitors can enjoy for many generations to come. A regular pruning schedule is in place for safety, health, structure and appearance. Provide root collar excavations to suspect trees. Buried root collars can contribute to a number of tree health problems, including girdling roots, basal cankers, masking root and lower stem decay, and predisposing trees to various insect and disease pests. Improve soil structures for existing and newly planted trees. A list of recommended tree species was created by the Committee to replace the aging and mature Pines on campus. Swamp White Oak - (Quercus michauxii) Bald Cypress - (Taxodium distichum) Dawn Redwood - (Metaseqouia glyptostroboides) Eastern Red Cedar - (Juniperus virginiana) Lacebark Elm - (Ulmus parviflora) Ginkgo - (Ginkgo biloba) Sawtooth Oak (Quercus acutissima) Chestnut Oak - (Quercus prinus) Japanese Maple (species) - (Acer palmatum spp.) American Hornbeam - (Carpinus caroliniana) Paperbark Maple - (Acer griseum) Japanese Blue Oak - (Quercus glauca) Chinese Pistache - (Pistacia chinensis) Dogwood (species) - (Cornus spp.) Chinese Evergreen Oak - (Quercus myrsinifolia) Bur Oak - (Quercus macrocarpa) Honey Locust - (Gleditsia triacanthos) Harry Lauder's Walking Stick - (Corylus avellana 'Contorta') Southern Magnolia - (Magnolia grandiflora) American Beech - (Fagus grandifolia) Deodar Cedar - (Cedrus deodara) American Holly - (Ilex opaca) Ironwood - (Ostrya virginiana) Smoke tree - (Cotinus coggygria) Japanese Cryptomeria - (Cryptomeria japonica) Washington Hawthorn - (Crataegus phaenopyrum) Shagbark Hickory - (Carya ovata) Black Gum - (Nyssa sylvatica) Chinese Chestnut - (Castanea mollissima) Grancy Gray-beard - (Chionanthus virginicus) Japanese Zelkova - (Zelkova serrata) American Yellowwood - (Cladrastis kentukea) Japanese Stewartia - (Stewartia pseudocamellia) Fig - (Ficus carica) Weeping Redbud - (Cercis Canadensis Covey ) Banana Shrub - (Michelia figo) Chaste-tree - (Vitex-Agnus-castus) Japanese Snowbell - (Styrax japonicus) Shumard Oak - (Quercus shumardii) 7. TREE DAMAGE ASSESSMENT Any damage to trees created by a contractor or outside sources will be evaluated and the costs of the damage, replacement or maintenance will be evaluated by the university. The party responsible for the damage will then be billed by the University for the damages incurred Clayton State University 8

9 8. PROHIBITED PRACTICES Planting, removing or pruning any trees without the approval from the Assistant Director of Landscape Management is prohibited. This is to prevent unnecessary damages to the existing tree population on campus. Signs from student organizations and departments shall not be nailed to trees and signs shall not be staked near newly planted trees. Improper pruning such as topping or terminal cuts are prohibited. Larger species of trees shall not be planted within 20 feet of a building to prevent roof damage and overcrowding. 9. DEFINITIONS OF TERMINOLOGY Term Invasive Dormancy Tree drip line Tree canopy Root collar excavations Cankers Topping Terminal cuts Definition Note native to and tending to spread widely in a habitat or environment. Invasive species often have few natural predators or other biological controls in their new environment. Although not always considered harmful to an environment, invasive species can become agricultural or ecological pests and can displace native species from their habitats. In a condition of biological rest or inactivity characterized by cessation of growth or development and the suspension of many metabolic processes. A ring around the tree canopy on the ground level that receives most of the rainwater shed from the tree canopy. Feeder root locations go beyond the drip line to get rainwater shed from the tree canopy. Feeder root locations go beyond the drip line to get moisture and nutrients being created from organic matter in and on top of the soil. A layer of multiple layers of branches and foliage at the top or crown of a forest s trees. A tree s root collar is the area where the roots join the main stem or trunk. This area is typified by a flare leading to the major roots. The root collar is part of the tree s trunk. Unlike roots, the trunk is not specialized to resist constant soil moisture. The movement of oxygen and carbon dioxide in and out of the phloem (inner bark) is inhibited by this water. Over a period of years the lack of gas exchange can kill phloem cells and interfere with the downward movement of food (photosynthate) to the roots. This can stunt root growth and lead to decline of the plant. Localized, often sunken, necrotic lesion, with well-defined margins. Inappropriate pruning technique to reduce tree size usually cut at internodes. A stem cutting consisting of a portion of a stem or branch with a terminal bud. 10. COMMUNICATION STRATEGY The Campus Tree Care Plan will be distributed on the Clayton State University Facilities Management website. Copies will also be filed with the appropriate administrative offices and campus security, and shared with all campus facilities personnel. Links to the Campus Tree Care Plan are also shared electronically with campus officials Clayton State University 9

10 STANDARD 3: Dedicated Annual Expenditures for Campus Tree Care Program Below are the expenditures for the Campus Tree Care Program at Clayton State University. Expense Tree Planting and Initial Care (Include cost of tree purchases, labor and equipment for planting, planting materials, staking, watering, mulching, competition control, etc.) Campus Tree Management (For example: include pruning, public education, professional training, association memberships, campus tree inventory, pest management, fertilization, tree removals (if needed), and all associated costs) Amount $ 18, $ 27, Volunteer Time (440 hours volunteer time X $22.00) Other Expenses (Tree Inventory) $ 9, $ 16, TOTAL $ 71, Number of trees planted 53 Number of trees pruned 63 (Based on an estimate, because pruning is done on-going in house by Landscape staff on an as-needed basis.)

11 STANDARD 4: Arbor Day Observance Clayton State University Tree Campus USA Clayton State and the Clayton State Tree Committee hosted the University s first Arbor Day Observance on Friday, April 26. The Arbor Day Ceremony and tree planting started on the University Quad, with Clayton State Vice President for Business and Operations Corlis Cummings providing the keynote address. Proving conclusively that CFO s are also philosophical, Cummings quoted Frank Lloyd Wright, the best friend of man on Earth is the tree. Cummings also noted that Clayton State s recycling program has saved 8000 trees. In addition half dozen Shumard Oaks were planted on campus on April 26. Following Cummings keynote, Associate Professor of Biology Dr. Jere Boudell spoke on Ecology and Plants of the Piedmont Trail, and noting that, we live in a tree community. As part of the Arbor Day celebration, Boudell officially inaugurated the campus Plants of the Piedmont Trail, located just across Swan Lake, on the pathway between the lake and Spivey Hall. Boudell pointed out that the trail not only provides identification signs for the trees on the trail, but there is even an app associated with the signs to further identify the trees. Following the speech-making, Boudell led tours through the Plants of the Piedmont Trail. Boudell and Tree Committee Chair Justin Brooks added that, although the campus already has many species of oak, including red, white, water and willow oaks, the Georgia native Shumard Oaks planted at various sites on the Quad and by the lake were the first of their type on campus. Doing the planting were local homeschooled children, who attended the event at the invitation of Spivey Hall Education Manager Catherine Giel Clayton State University 11

12 STANDARD 5: Service Learning Project W. H. Reynolds Memorial is a 146 acre nature preserve located in the heart of Clayton County in Morrow, GA. The land, preserved in its native state, is a perfect example of rolling hills in the Piedmont region of Georgia. With over 3 miles of hiking trails a visitor can explore the highest ridges in the county in a mixed oak-hickory-pine forest down to the wetlands and ponds fed by natural springs. One can also take the opportunity to step back in time and admire old farm equipment, spring houses, and a barn dating back to Reynolds Nature Preserve s annual Wild Azalea Festival was held on Saturday, April 6 at the Reynolds Nature Preserve. Guided hikes, live animal shows, nature center exhibits, face painting, native azalea showcases, hands on workshops, informational booths from local environmental organizations were just a few activities that occurred at the festival. Clayton State faculty and students participated in service learning projects at the festival. Dr. Barbara Musolf and Tri Beta members provided educational material about invasive plants. Dr. Christopher Kodani and students presented an adopt-a-stream protocol. Dr. Jere Boudell gave a presentation on stream restoration and her SEEDS students discussed ecology and ecological issues Clayton State University 12
