Trees represent on of the most valuable components your property has to offer.
They not only provide the framework in which your architecture is viewed, but is also an important element relating to human activities and environmental quality.
Managing the health of urban trees has always been challenging. There are thousands of different tree species, each with their own cultural requirements and all prone to a variety of pests and diseases. Arbortech’s trained staff can provide you with the most up to date information available for your plant health care needs.
Benefits of Pruning
How Important is your Soil
Many cities and counties have specific guidelines to follow for fire safety. The following is an overview of standard practices for fire safety.
WEED ABATEMENT GUIDELINES
What are the Minimum Abatement Standards?
FOR LOTS/PARCELS UNDER 3 ACRES
All combustible rubbish, trash, trimmings, or litter which presents a fire hazard shall be removed from the property.
All combustible materials of value being stored outside of a building shall be neatly stacked and have all combustible growth cleared for 30 feet around it.
Mowing is the abatement method encouraged by the City, and should be at a maximum of 6 inches.
Maintain the roofs of all buildings or structures free of leaves, needles, twigs, and other combustible matter.
TREES – Remove any portion of a tree which extends within 10 feet of the outlet of a chimney or stovepipe.
Maintain 5 feet of vertical clearance between roof surfaces and portions of trees overhanging any building or structure.
Maintain volatile tree species (including Acacia, Cedar, Cypress, Eucalyptus and Pines) within the City of Fremont Hazardous Fire Areas so that no leafy foliage, twigs or branches are within 10 feet of the ground.
Maintain non-volatile trees within 100 feet of any building or structure or within 10 feet of that portion of any highway, street, alley, or driveway which is improved or used for vehicle travel or other vehicular purposes, so that no leafy foliage, twigs or branches are within 5 feet of the ground.
On Parcels Greater than 3 Acres
Provide 30–foot firebreaks and crossbreaks.
Provide crossbreaks which divide the parcel into approximately 5–acre sections.
Firebreaks and crossbreaks are a continuous strip of disced, dozed, or mowed ground, following as closely as possible to the property line and along one side of all fence lines, ditches, and on top of all ridges.
When terrain is too steep or rugged for a tractor, a mowed firebreak may be required.
All residential structures on parcels over 3 acres must have a 100-foot firebreak and other structures a 30-foot firebreak (disced, landscaped, or mowed) around them.
Cabling and Bracing
The installation of cable and bracing systems are used for a variety of reasons to reduce the potential of limb or trunk failure. There are many reason trees fail, such as; structural defects, included bark, poor crotch angles, co-dominant laterals, and rot or decay just to name a few. If you have large trees on your property, a Certified Arborist can spot potential hazards and make recommendations to help you choose the best course of action.
Why We Do Not Top Trees
Topping is the drastic removal or cutting back of large branches in mature trees. All too often, we see clients that have their trees topped, when they reach heights they consider to be unsafe. These fears are largely unjustified and have long term damaging effects to the trees and to the surrounding community. Many cities and public agencies have now implemented standards to prevent this type of pruning.
EIGHT REASONS WHY TREES SHOULD NOT BE TOPPED:
Starvation – Trees need leaves to manufacture starches during photosynthesis. A trees transport system move starches from the leaves to the roots. Topping removes the leafy crown that provides the root system with necessary nutrients.
Sun Scald – Sudden removal of the leafy protective layer exposes the bark to sun scald.
Insects and diseases – Large wounds prevent the natural defense system from functioning. The open wounds invite insect invasions and the spread of decay forming fungi.
Weak limbs – New fast growing sprouts emerge from topping cuts which have a tendency to fail due to weak attachment to the parent branch.
Rapid new growth – People believe they should top trees to control height and spread of tree. Actually, the opposite happens. Trees respond rapidly to injury by producing fast growing, long sprouts quickly resulting in the tree regaining or exceeding the height it once had.
Tree death – Some species of trees do not tolerate topping. The resulting lack of folage severely reduces the trees ability to capture sunlight and turn it into glucose, which in some cases leads to the death of the tree.
Ugliness – Topping disfigures the trees natural beauty and grace, which can never be regained.
Cost – The cost can be measured in many ways such as reduced property value, loss of other trees and shrubs that succumb to the environmental changes, risk of liability from branch failure, and increased future pruning costs.
Trees & Construction
Construction specifications typically include notes and details specifically designed to protect existing trees. Arbortech has worked with both public agencies and contractors to minimize damage to existing trees and to ensure that construction guidelines are met. Arbortech works directly with contractors, architects, and designers for the purpose of developing tree protection plans, surveys, site evaluations and mitigation.
