Registered Consulting Arborist #443 Board Certified Master Arborist FL -0501 B Page 3 of 15 3/6/16 Selva Preserve Introduction Background We were asked by Ryan Carter of Carter Environmental Services, Inc. to perform a tree condition survey of the approximately 7.21 -acre parcel known as Selva Preserve. After walking the site and not distinguishing significant variation in the tree species and sizes from one area of the parcel to another, we all agreed that a randomized sample tree survey would provide an accurate profile of the tree species, their sizes and their condition. We received approval to do the sample survey on February 26, 2016 and we completed the survey in less than one day on March 3, 2016. I was assisted with the survey by my partner, ISA Certified Arborist Danny Lippi and Michael Spontak GIS Analyst /Project Scientist from Carter Environmental Services, Inc. Assignment Our assignment was to locate and assess the current condition of trees equal to or greater than 12 inches DBH located in ten 1/10 -acre sectors randomly selected within the Selva Preserve but outside designated wetlands. See Appendix A for the location of the ten 1/10 acre sectors. Broadleaf trees and pine trees smaller than 12- inches DBH and all sabal palm trees (Sabel palmetto) were not evaluated. We rarely evaluate sabal palm trees because they are generally healthy and free of significant structural defects that might make them hazardous. However, if we observe a diseased or structurally defective palm as we walk through the area, we will note such palms. None were noted on this survey. Purpose and Use of the Report This report is prepared for Carter Environmental Services, Inc. and their clients to be used in its entirety. Assumptions A field examination of the site was made on March 3, 2016. Our observations and conclusions are as of that date. Testing and Analysis Chuck Lippi, Advanced Tree Care, Inc. Registered Consulting Arborist #443 Board Certified Master Arborist FL -0501 B Page 4 of 15 3/6/16 Selva Preserve We performed a Level 2 Basic Assessment, which is a detailed visual inspection of a tree and its surrounding site. The Level 2 Assessment includes a 360- degree visual inspection from ground level on the tree and sound testing of the accessible portions of the trunk with a rubber mallet to listen for tonal variations that may indicate dead external tissue or internal hollows. The inspection was done in accordance with ANSI A300 Standards on Tree Risk Assessment and the companion publication Best Management Practices, Tree Risk Assessment. Data Collection Both empirical data as well as subjective data were gathered on each tree. Data was collected on HanDBase, a data collection database application used on our smartphones. Empirical data included: 1. GPS assigned tree number and location 2. tree species 3. tree diameter (DBH) The subjective data included: 1. health condition (excellent, good, fair, poor) 2. structural condition (excellent, good, fair, poor) 3. structural problems such as codominant leaders, dead branches, decay/ cavities, health problems such as decay fungi, sparse foliage, declining 4. tree condition rating Tree Condition Rating In order to quantify the overall condition of the trees we surveyed, we adapted the risk rating rating system from the Tree Risk Assessment Procedures by combing the following attributes: ' American National Standards Institute (ANSI) A300 Risk Assessment Part 9 Tree, Shrub, and Other Woody Plant Management Standard Practices (Tree Risk Assessment a. Tree Structure Assessment), 2011. 2 Thomas Smiley, Nelda Matheny and Sharon Lilly, Best Management Practices Tree Risk Assessment, International Society of Arboriculture, Champaign, Illinois, 2011. 3 GPS measurements and data were collected and stored by Carter Environmental Services, Inc. to be added to our tree condition data Chuck Lippi, Advanced Tree Care, Inc. Registered Consulting Arborist #443 Board Certified Master Arborist FL -0501 B Page 5 of 15 3/6/16 Selva Preserve 1. tree health condition (excellent 4 points, good 3 points, fair 2 points, poor 1 point) 2. structural condition (excellent 4 points, good 3 points, fair 2 points, poor 1 point) 3. species rating (2 points for a desirable tree, and 1 point for a Tess desirable tree) 4. likelihood of failure (unlikely 4 points, possible 3 points, probable 2 points and imminent 1 point) The Condition Assessment rating is a subjective measure of relative condition of a tree based upon the four factors above. There are 14 possible points indicating Trees per Sector BEI (C, _ D,11 fG 7i B, 13 - f A, 8 Figure 1 Each sector where trees were surveyed is indicated by a letter A through J followed by the number of trees located in that sector.

See the Overall Condition Rating in Figure 6 on page 10. Observations The Trees We evaluated 64 trees in the 10 random sectors. Sectors were assigned a letter from A through J. The number of trees per sector varied from two trees to 13 trees (Figure 1). The trees were mostly Florida native species which include slash pine (Pinus elliottii), sugarberry (Celtis laevigata), red maple (Acer rubrum) and laurel oak (Quercus laurifolia) and smaller numbers of other species. Sixty one of the 64 trees were species considered by most arborists to be lesser species mainly because they are known to have moderate to poor wind resistance, moderate to poor decay resistance and relatively short average lifespans. These species are generally the first to populate a once - cleared site and will eventually succumb to larger, longer -lived species such as Southern magnolia (Magnolia grandiflora) and Southern live oak (Quercus virginiana) and the sand live oak (Quercus geminata) unless the area is overgrown with invasive species such as camphor (Cinnamomum camphora) and Chinaberry (Melia Chuck Lippi, Advanced Tree Care, Inc. Registered Consulting Arborist #443 Board Certified Master Arborist FL -0501 B Page 7 of 15 3/6/16 Selva Preserve azedarach) which are already found on the site. The distribution of the tree species found is shown in Figure 2. The Site The site is a once cleared successional mesic forest site with intermittent wetlands. Changes to the water table with the construction of nearby canals appears to be causing root slippage and wind throw of trees in saturated areas and possible subsidence and exposure of roots through the decomposition of organic soil constituents where the water table has been lowered. Native vine growth of poison ivy, wild grape, smilax and Virginia creeper are also overtopping and suppressing a significant number of the trees on the site.

Registered Consulting Arborist #443 Board Certified Master Arborist FL -0501 B Page 8 of 15 3/6/16 Selva Preserve Tree Health and Structural Condition Each tree was also evaluated as to its overall health and structure. It is important to understand that health and structure are two separate and independent considerations. A tree can be healthy yet have poor and hazardous structure. Live (green) trees can fail and sometimes do. Structurally sound trees sometimes decline and die from poor health. Figure 3 shows both the health condition and the structural condition of the trees surveyed. Tree health was slightly better than tree structure but most trees surveyed were ranked as good. No trees were ranked as excellent in either heath or structure.

Ninety -five percent of the trees surveyed were in the less desirable species category (Figure 4). LIKELIHOOD OF FAILURE probable unlikely 16% 8% possible 76% Figure 5 Likelihood of Failure The likelihood of failure is a methodology used in tree risk assessment as a guideline: •Improbable: The tree or branch is not likely to fail during normal weather conditions and may not fail in many severe weather conditions within the specified time frame. 4 Julian A.

Seventy six percent of the trees surveyed had a possible likelihood of failure and only eight percent were unlikely to fail. See Figure 5. Tree Age/Size Examining the tree trunk diameters surveyed indicates the tree population on the site is relatively young (Figure 7). A majority of the trees surveyed are between 12 inches and 20 inches DBH. And few are over 24 inches DBH. Although tree trunk diameter will not give us a precise tree age, it is very indicative of the relative young age of the tree population on the site. Conclusions The trees surveyed are young and in relatively good health and structural condition. However, most of the trees have a short lifespan and are species that have documented moderate to poor wind resistance and moderate to poor ability to compartmentalize or resist decay. The site is rather unremarkable with no notable specimen trees especially live oaks that leave the surveyor in awe when he or she encounters them because of the live oak's massive size. 5 Dr. Mary Duryea and Eliana Kampf, Wind and Trees: Lessons Learned from Hurricanes, University of Florida publication FOR 118, September, 2007, 17 pages. 6 Dr. Ed Gilman, Dr. Mary Duryea, Dr. Eliana Kampf, Dr. Traci Jo Partin, Dr. Astrid Delgado, Dr Carol Lehtola, Assessing Damage and Restoring Trees After a Hurricane, University of Florida Department of Environmental Horticulture Publication ENH1036, 2006, pp. 10 - 11.
