  • 1. Plant the Right Tree in the Right Place The Florida Native Plant SocietyJimmy Socash, ASLA, JFS Design Inc.Pembroke Pines, Fl.

2. Right Tree-Right Place History... Long Standing Statement-18th Century! Post WWII Urbanization Importance to plant treesin the urban landscape 3. Right Tree-Right Place Today... The National Arbor Day Foundation Tree City USA Bulletin Utility Companies Temperate to Tropical 4. ENVIRONMENTAL LANDSCAPE DESIGN: Use plant material that is native and self sustaining. Increase the life expectancy of plant material with Right Place right installation and right maintenance methods. Reduce unneeded maintenance: trimming, shaping, fertilization, pest control. Reduce water consumption. Incorporate BIODIVERSITY through introduction of newor little-used native species. 5. Agencies and Organizations Implementing and usingRight Tree-Right Placeprinciples National Arbor DayFoundation Municipalities andgoverning agencies Utility Companies 6. IFAS Florida Friendly Yards Program 9 Principles:1. Right Tree; Right Place2. Water Efficiently3. Fertilize Appropriately4. Mulch5. Attract Wildlife6. Manage Yard Pest Responsibly7. Recycle8. Reduce Stormwater Runoff9. Protect the Waterfront 7. Naturescape - Broward County Incorporation of Florida-Friendly landscapes to conserve water, protect water quality, and create wildlife habitat.Important part of Broward Countys Integrated Water Resource Plan (IWRP) 8. Use of Native Trees... LIVE OAK GUMBO LIMBO Quercus virginiana Bursera simaruba 9. Use of Native Trees... JAMAICA CAPERSIMPSONS STOPPER Capparis cynophallophora Myricianthes fragrans 10. Native Palms... SABAL PALM Sabal palmetto ROYAL PALM Roystonea elata 11. Native Palms... SILVER THATCH PALM Thrinax morrissii FLORIDA THATCH PALM Thrinax radiata 12. Native Palms... ROYAL PALM Roystonea elata 13. Focus 50% of the Earths population will be urban Urban Heat Islands Right Tree-Right Place Tropical Urban Environments Step to carbon sequestration 14. Principles of Right Tree-Right Place 1. EnvironmentalFactors 2. Right Tree Factors 3. Right Place Factors Bill OLeary 15. 1. Environmental Factors Temperature- minimum and maximum year round climatic Precipitation and Moisture- climatic Altitude- (especially pertinent in tropical areas) Soil Conditions Pests and susceptibility to local diseases Air Pollution (urban areas) 16. 2. Right Tree Factors... Ultimate mature size Canopy and root zone requirements Pruning maintenance program Debris-seed, fruit, leaf dropWILD TAMARINDLysiloma spp. 17. 2. Right Tree Factors... Deciduous or evergreen (tropical trees also) Growth habit, form, crown and shape Shade and Cooling- temperature moderation factors Esthetics- flowering trees, esthetic shade value, vista and view value GUMBO LIMBO Bursera simaruba 18. 3. Right Place Factors... Highways and byways-sight triangles,streetscapes, medians Buildings- proximity to,framing and screening Overhead andunderground utilities-electrical, water, sewer,tv, telephone Along walkways,courtyards and small SILVER BUTTONWOODurban parks Conocarpus erectus var. Sericeus 19. 3. Right Place Factors... Limited root zone area Encroachments on toadjacent properties Parking lots andparking islands SABAL PALM Sabal palmetto 20. Consequences of Planting the WRONG TREE in the WRONG PLACEInappropriate use of NATIVE Tree Species MAHOGANY Swietenia mahagoni 21. Wrong Tree Consequences Wrong tree, Wrong Place damage to infrastructure, roadways, buildings, utilities Shortened life span of plant material Trees, Palms, etc. Excessive Maintenance trimming, mowing, shaping, excessive irrigation, fertilization, weed and pest control, use of petro-chemical derivatives gas-powered machines,causing increased global warming 22. Wrong Tree-Wrong Place 23. Wrong Tree-Wrong Place Prioritize Emergency Vehicular Access Design: Eliminate Potential Roadway Obstructions 24. Trees Susceptible to Toppling Obstruction of Waterways and Canals Invasive Exotics Are Susceptible to Toppling Inhibiting Drainage and Causing Upland Flooding Design: Evaluate Situations, Remove Exotics, Use ofNative Habitat Restoration. 25. Species Susceptible toBreakage Same Consideration as Toppling Evaluate and Design Accordingly 26. Right Tree-Right PlaceJimmy Socash Bill OLeary Bill OLeary 27. Right Tree-Right Place 28. Shade Value for our sub-tropical urban landscape 29. The sorry status of our urban tree canopy33% - Nation-wide Average10% - Miami-Dade County Average3% - Hialeah(American Forests Survey, 1996) 30% TREE CANOPY GOAL for MIAMI-DADE STREETTREE MASTER PLANBy 202011 years ! ! ! 30. Planting Opportunities in the urban environment 31. Planting Opportunities... 32. Planting Opportunities... 33. CPTED Crime Prevention Through Environmental Design 34. Project Implementation Quality grown plant material-Grades and Standards Contract growing Competent landscape inspections Rejection of unacceptable plant material Maintenance-initial and long term, and its importance. 35. Benefits Benefits of greening of urban sub-tropical areas: Economical Environmental Social Esthetics Focus on attainable short-term goals and projects. Maintain perspective of long-term goals. 36. Trees, Urban Environments, and Soil Volumes 37. Preserve Existing Trees... 38. Preserve Existing Trees... 39. Meeting the Goals of the Miami-Dade County Street Tree Master PlanPlanningPlantingPruningEducation and GrowthBest Management Practices (BMP)ROOT ZONE GROWING AREA Design the soil space under and adjacent to the hardscapeto sustain root growth good trees well connected to theground only develop if the roots have room to growMiami-Dade County Street Tree Master Plan Page 7- March 2007 40. The major impediment to establishing trees in paved urban areas is the lack of an adequate volume of soil for tree root growth.Urban Horticulture InstituteDecember 2000 41. Trees Growing in Confined Soil Spaces are Prone to Toppling Rate of growth is greatly reducedand will be short- lived. Better to plant a 50 cent tree in a 5 dollar hole than a 5 dollar tree in a 50 cent hole 42. Make Bigger Planting Spaces.Mi nMaaxxMMi n?JAMES URBAN, FASLA, ISA Balance the size of paved and soil areas. 43. How Much Soil ? Larger Trees1200 CFSoil Volume =20 x 20 x 3 depth20 TrunkDiameter e e siztre meof u o vol ti l Ra soito More SoilJAMES URBAN, FASLA, ISA20 Trunk Diameter Tree will require20 x 20 x 3 deep soil volume (min.). 44. Make Space for Roots. JAMES URBAN, FASLA, ISA Design spaces for roots under the pavement and utilize different approaches to root space design as conditions change 45. Roots grow well beyond canopy edge Dr. Ed Gilman, U of Florida Trees that normally grow a very expansive root system can become stressed and grow poorly in urban landscapes where soil space is limited The result can be poor tree health, damaged sidewalks and curbs, and other problems 46. Downtown Kendall Urban Center DistrictStreet Trees: minimum caliper of six (6) inches and a minimum clear trunk of eight (8) feet at the time of planting.

CU-STRUCTURAL SOILS... Cornell University Comprised of two main components: 1. Rigid Stone latticeLattice are load-bearing stones for stability andinterconnected voids that allows root penetration, air andwater movement.2. Quantity soil (heavy clay loam or loam)Clay holds most of the water and nutrients.WithGelscape Hydrogel combines with the mix and works as a non-toxic, non-phytotoxic tackifier. 49. CU-STRUCTURAL SOILS AND PERMEABLE PAVEMENTS 50. CU-Structural Soils and Permeable Pavements... Street trees CU-Structural Soil helpscreate large enoughvolumes of soils underconstructed pavements. CU-Structural Soil shouldhave a depth of at least 24,but it is preferred to have36. Parking Lots and Plazas Trees planted in LandscapeIslands will benefit from CU-StructuralSoils and PermeablePavements. 51. DeepRoot Silva Cell... 52. Deeproot Silva Cells...

Expanded soil-volumes reduce rainfallrunoff 56. Deeproot Silva Cells...JAMES URBAN, FASLA, ISA 57. Structural Cell Applications JAMES URBAN, FASLA, ISA Trees and Rainwater Harvesting 58. Permeable Pavements When integrated with CU- Structural Soils or Deeproot Silva Cells Vegetation is watered, reducing the need for irrigation Ground water is rechargedWater resources are preservedStormwater runoff is reducedStormwater runoff quality is improved.www.CoolCommunities.org 59. Permeable Pavements U.S. GREEN BUILDING COUNCIL (USGBC) LEED (Leadership in Energy and Environmental Design) CERTIFIABLEPervious pavements can be made of concrete, asphalt, open-celled stones, and gravel, thatare mixed in a manner that creates an open cell structure allowing water and air to passthrough. For example, porous concrete can pass 3-5 gallons of water per minute, which is fargreater than most conceivable rain events and highly effective in cont
