I. Executive SummaryTrees within Macon State College grounds were inventoried to assist in managing treehealth and safety. 500 trees or tree groupings were identified of 40 different species.Trees inventoried were 6 inches at DBH or greater. The attributes that were collectedinclude tree Latitude and Longitude, and a visual assessment of tree structure, health, andvigor. The documentation of these attributes will help in future management decisionsrelative to tree health, preservation and safety.Attribute collection for the tree inventory was conducted using a sub-meter accuracyGPSr device having an error in location not greater than 3 meters.Specific recommendations for the subject trees over the next 3-year period include: Removing 4 trees (1%) to eliminate potential hazards to eliminate trees inadvanced stages of decline, or to improve habitat for desirable trees close byPruning 363 trees (73%) for safety, health, structure, and appearance. Pruningwill comply with American National Standards Institute (ANSI) A300Z pruningstandards for arboricultureSupport system installation in 34 trees (7%) to reduce branch and crown failurepotentialProviding tree risk assessments for 29 trees (5%) to evaluate the impact of wooddecay in stems and buttress roots that show potential for failure.Providing root collar excavations to 65 trees (13%). Buried root collars cancontribute to a number of tree health problems, including girdling roots, basalcankers, masking root and lower stem decay, and predisposing trees to variousinsect and disease pestsImplementing an integrated pest management program to monitor pests anddiseases on the subject trees. Treatments are therapeutic and preventive.Treatment timing is based on pest life cycle.Implementing Bartlett’s “Root Invigoration Program” (patented by the F.A.Bartlett Tree Expert Company) for trees affected by construction/ storm activitieswill improve soil density and promote new root growth, especially for high-valuetrees in disturbed areasTaking soil samples throughout the campus. Soil analysis provides information onthe presence of soil nutrients, pH, organic matter, and cation exchange capacity.Taking bulk density samples throughout the grounds to determine the amount ofsoil compaction.Implementing a storm damage plan for those trees affected by tornados in 2008.The plan will include pruning, soil, and pest management programs.1

II. IntroductionIn the winter of 2009 Bartlett Tree Experts was retained to perform a tree inventory forthe Macon State College in Macon, GA. The inventory included: Identifying the trees’ condition, health, and vigor (Trees were 6 inches andgreater at DBH)Recommending hazard evaluations and removals of appropriate treesRecommending pruning, soil management, and pest management treatments topromote tree safety, health, and longevityMapping the trees using Global Positioning Satellite Receiver (GPSr) hardwareand Geographic Information System (GIS) softwareThe following report contains the findings and recommendations of the tree inventory.The Bartlett Visual Tree Structure Analysis System ranks the relative degree of risk forprioritizing remedial treatments when managing large tree populations. Bartlett’s systemuses two criteria: Failure Potential and Consequence of Failure. Failure potentialconsiders the severity of defect, architecture, site exposure and other biological and sitefactors that contribute to failure as observed from the ground. Consequence factors in sizeof the defective plant part, target value and frequency of use and potential for injury/lossshould a failure occur as observed from the ground.Failure Potential(FP)Critical Risk - Failure imminentHigh Risk - Failure likely especially in stormsModerate Risk– Failure possible especially in severe stormsLow Risk – Failure unlikelyPoints10 7 - 104-61-3Consequence of Failure(CoF)This criteria considers potential for injury/loss should a failure occur based on suchfactors as size of defective plant part, target value and frequency of useSevere Consequence – High potential for injury/property lossModerate Consequence – Moderate Potential for property loss,Low potential for injuryLow Consequence – Low Potential for any loss53-41-2Total Visual Tree Structure Analysis Failure Potential Consequence of Failure2

Total Visual Tree Structure Analysis(VTSA)Comments13-15Critical Risk- Failure imminent;Personal injury and/or property damageinevitable.10-12High Risk- Failure likely especially duringstorms; Personal injury and/or propertydamage likely.7-9Moderate Risk-Failure unlikely, and/orhigh risk of failure and low risk of propertydamage/personal injury 7Low Risk-Failure unlikely and low risk ofproperty damagePruning and structural support system procedures will reduce the risk of branch andleader failure to an acceptable level. It must be emphasized however, that all large treespose a certain degree of inherent risk and this evaluation does not preclude all possibilityof failure especially during severe storms.For those trees that the client considers hazardous and representing an immediate safetyconcern, we recommend placing a sign, tape, or other warning device near those treesuntil such time as the hazard can be remedied.The material is presented in both printed and digital formats, and instructions for digitalviewing follow:To view digital maps, install “Arc Reader 9.3” /index.htmlWhen the web page opens, click on Download Now, and follow the prompts.After Arc Reader is installed, you can open the “Macon State.pmf” file (included on thedisk) to see the information.On the disk, unzip the “Macon State. zip” file to your C-drive (C:\). It is important thatyou unzip the “Macon” file directly to your C-drive, or you will be unable toview the maps with ArcReader. After, the file has been unzipped, navigate to C:\ MaconState, and open the folder. Within the folder will be the “Click here to open.pmf” file.To view the entire spreadsheet of tree information for the site, open the “MaconState.xls” file.To view a digital copy of the Inventory/ Management Plan, open the “Macon StateCollege Tree Inventory and Management Plan 2009.pdf” file.3

III. Inventory ObjectivesManagement objectives for the subject trees are as follow: Maximize immediate and long-term tree health and aesthetics througho integrated pest managemento soil managemento maintenance pruningManage immediate and long-term risk associated with trees in high-use areasincluding use ofo hazard pruningo required removalso tree structure evaluationsIV. Inventory Procedures and DefinitionsThe Bartlett BIS team completed the tree inventory using Trimble GeoXT GPSrhardware and ArgGIS 9.3 and Arborvue GIS software. The following tree attribute datawere collected on site: Botanical Name/ Regional Common Name according to local ISA Chapter TreeSpecies List.Tree location based on GPS coordinate systemTag NumberDiameter at Breast Height (DBH)Canopy RadiusAge Classo Young - Established tree that has not been in the landscape for many yearso Semi-mature - Established tree that has not yet reached full growthpotentialo Mature - A tree within its full growth potentialo Over-mature - A tree that is declining or beginning to decline due to itsageo New Planting - A tree that is not yet establishedHeight Classo Small - 15'o Medium - 16' - 35'o Large - 35'4

Condition Classo Deado Poor - Most of the canopy is affected with die-back, undesirable leaf color,undesirable leaf size and undesirable new growth. Tree or parts of the treeare in the process of failure.o Fair - Parts of the canopy affected by undesirable leaf color, undesirableleaf size and undesirable new growth. Parts of the tree are likely to fail.o Good - Tree health and condition are acceptable.Root Zone Infringement (Based on dripline, estimate grayscape (man-madestructures, such as sidewalks) impact on root zone)Infrastructure Interaction (Interaction between trees and grayscape that may causean undesirable condition)Priority of General Tree Work (Based upon a 3-year management plan).

i Macon State Stand DynamicsAs part of the Bartlett inventory process and using ArborVue software, we have included anestimated value for each tree and cumulative total for all trees inventoried. The estimated value iscalculated using a modified form* of the “Trunk Formula Method” published by the Council ofTree and Landscape Appraisers in The Guide for Plant Appraisal, 9th edition. The figures aregood estimates of tree values but should not be used in lieu of a formal tree appraisal whereprecise assessments are required.ArborVue software uses the following data fields in this formula:Estimated Value:Size * Species Factor * Condition Factor * Location ValueSize:Based on tree diameter at breast height in inches (DBH diameterat 4.5 feet)Species Factor:The relative species desirability based on 100 percent for the treein that geographical location. In most cases, species desirabilityratings, published by the International Society of Arboriculture, are usedfor adjustment.Condition Factor:A rating of the tree’s structure and health based on 100 percentLocation Value:An average rating for the site and the tree’s contribution andplacement, based on 100 percent*The modified Trunk Formula Method used does not consider cost of purchase and installationof the largest available “like tree.”The cumulative total value for all trees inventoried is: 2,138,661The following table lists the 10 trees with the highest estimated values:Tree ID CommonDiameter Estimated Value371 sweetgum53 30,225225 live oak45 30,168314 water oak40 27,587285 pecan46 27,282386 sweetgum32 20,26071 southern red oak40 19,70589 live oak33 18,618319 live oak32 17,559315 loblolly pine30 16,963193 live oak30 15,75113

ii. Macon State Tree Evaluation and Removal RecommendationsAs part of this inventory, the Bartlett BIS team conducted visual inspection of each tree from theground. For the trees listed below, some aspect of tree structure or health indicated that furtheranalysis is necessary to more completely evaluate tree condition and risk, and to make amore informed decision about managing each tree.Tree structure evaluations are recommended to evaluate impact of wood decay in stems andbuttress roots that show potential for failure. Detailed tree structure evaluation may requireclimbing the tree, and using diagnostic tools to more thoroughly determine the nature and extentof defects and decay. Evaluation may also require detailed examination of the root system usingair excavation. An experienced ISA Certified Arborist using a “tree structure drill bit” or IMLresistograph (preferred method) can evaluate degree of strength loss due to wood decay.Recommendations for tree maintenance are made after evaluation is complete.
