Live Oaks

Slide2The problem
Live oaks are key to the charm of New Smyrna and often property value. Live oaks tend to be vulnerable to the high winds of hurricanes. New Smyrna’s goal is to find long-term or other care in which will help make the live oaks less vulnerable to these winds.
Slide3Hurricane Season
1851-2017
166 years
Average direct hits among other states: 19
Florida: 11740% US hurricanes strike FloridaLive oaks tend to fail at 130 mph winds and aboveCategory 4 and 5
Live Oak’s Strength
Known for strength
About 90% survival rate in hurricane winds
Heavy rainfall causes less friction between roots and soil
May lead to weakened roots causing uprooting in hurricanes
Property Value
May live to be 100 years or older
Up to $30,000 in property value
May act as a windbreak to your home
Can grow up to 60 feet tall
Considered evergreens
Slide4Where oaks live
Americas, Asia, Europe, and North AfricaWidespreadDifferent species acclimated to different climatesCool climates to tropicalQuercus virginiana is known as the southern live oakCommon in Florida
Florida
Frequent direct hurricane hits
Average annual precipitation: about 59 inchesAverage high temperature: 79.5 degrees FAverage low temperature: 55.7 degrees F
Current Care
Tree removal requires a permit
Property owners determine the care of their treesCity trees are generally pruned once a yearAny endangerment to people or public property enables immediate removal (city trees)
Where They Live
Slide5SOLUTION
Care Is Key
The specificity of long-term care and maintenance of a live oak largely determines its survival rate against hurricane winds.
Slide6General Care
Plant with topsoilYoung trees do not require regular trimmingAll live oaks require regular irrigationGranular fertilizer 3 times a yearSpring, summer, and autumn
Slide7Requires a deep water tableHigh water tables cause less friction between roots and soilLess stabilityNo extra material closely surrounding their baseEx: mulch, flowers, etc.Mulch keeps bark moistWeakens baseInsects and bacteriaRooting spaceAccommodate for sizing
The Base(ics)
Slide8Root flaresEmerging support roots Should be partially above soil lineDamaged or underdeveloped flares create instabilityHazardousIncreases likeliness of being uprooted
Exposed Flare
Covered flares
Urban tree’s flares are commonly covered
Shorter life span
Premature defoliation
Delayed leaf set
Poor shoot elongation
Suffocate feeder roots
Cause stress
Girdling roots are not visible
Slide9Root Flare vs Covered
Slide10Damage Avoidance
Grouping creates wind barriers between treesTrees growing in groups (of 5 or more) as opposed to individually have a higher survival rateGrowing within 10 feet of one-another not side-by-sideStructural pruningReduces loose debrisRemoval of dead/unhealthy treesEndanger lives and propertyRequires a permit

Slide11Synopsis
Care and Damage Avoidance
Live oaks should be thoroughly cared for from their base to their branches. As many damage avoidance methods possible should be put in place as these pertain to placement and specific maintenance.
