April 25 is Arbor Day: Celebrate Trees with the Help of a Certified Arborist

New York, Apr 15, 2003

In neighborhoods across the nation, a long winter is finally giving way to spring, announced by warmer weather and the proliferation of green buds on tree branches. The season is blooming just in time for National Arbor Day, celebrated each year on the last Friday in April. Founded by J. Sterling Morton in Nebraska in 1872, Arbor Day is a nationally celebrated observance that encourages tree planting and tree care.

The National Arbor Day Foundation recommends many ways to celebrate, including paper recycling drives, dedication of a forest or tree, and of course, tree plantings. The organization also encourages neighborhood organizations to get their members to adopt and care for street trees in front of their homes. With professional assistance from a certified arborist, our leafy friends will continue to thrive in our backyards, parks and forests.

The National Arborist Association, now the Tree Care Industry Association (TCIA), is an ANSI member and ANSI-accredited standards developer that actively participates in the development of performance standards for the professional arborist. TCIA serves as the secretariat for the ANSI-accredited Standards Committee A300 that maintains a series of standards for Tree Care Operations (ANSI A300 Part 1-2001; Part 2-1998; Part 3-2000).

There are currently three American National Standards in the A300 family. These provide definitions for tree care maintenance and performance standards for tree pruning operations, utility line clearance and tree-pruning specifications. In addition, they promote healthy pruning and fertilization practices as well as procedures to protect and treat trees from pests and diseases. These standards dictate the requirements and recommendations of the tree care industry for satisfactory performance of tree care maintenance. This means tree care companies who perform work according to A300 standards are following accepted industry practices for tree care maintenance operations.

Another TCIA standards committee maintains the ANSI Z133.1 Standard, Pruning, Trimming, Repairing, Maintaining, and Removing Trees, and Cutting Brush-Safety Requirements. Z133 is the industry standard for safe work practices, and stresses that all professionals engaged in tree care operations must be familiar with these safety standards in order to protect employees and provide the safest work environment possible.

The International Society of Arboriculture (ISA) is an ANSI member dedicated to fostering a greater appreciation for trees and to promoting the research, technology and practice of professional arboriculture. ISA-certified arborists agree in writing to perform all work to ANSI A300 standards. ISA's certification program ensures the skills and qualifications of an arborist in twelve domains:

    Tree Risk Assessment Biology
    Soil/Water Relations
    Tree Preservation/Construction

Celebrate Arbor Day this April 25th by planting a tree, and rely on a certified arborist for its care and protection to carry it through a healthy lifetime.
