What do all of the ANSI terms mean?

TCIA has developed a comprehensive dictionary called the Green Industry Standards Dictionary, which explains the industry terms and definitions.

How does the ASC A300 develop standards?

The committee meets regularly to develop standards and respond to comments from tree care professionals like yourself. The committee is comprised of representatives from green industry organizations, such as TCIA, ISA, SMA, PGMS, UAA, ASLA, PLANET, and ASCA, governmental agencies, such as USFS and NPS, and private tree care companies. As standards are being developed, each organization and company asks members and employees to review and comment on each draft.

Before a draft standard is approved as an ANSI standard, the draft is submitted to at least one public comment period so all affected parties can review the draft. Public comments are often incorporated into the draft standard. With this open process, the committee strives to develop a fair, industry-consensus standard.

How can ANSI A300 standards help my business?

These standards were developed so arborists and plant maintenance managers can write accurate work specifications that follow accepted tree care industry practices. With written work specifications, you can compare “apples to apples” and “oranges to oranges.” Arborists should include pruning specifications as part of their estimates and/or contracts. In this way, professional tree care companies can provide clients a way to compare one bid to another, giving reputable businesses protection from dishonest competitors.

Those who say they will deliver the same service at a lower price, but only provide a fraction of that service, can be exposed with written work specifications. Managers can put work out to bid with specifications already included or can require that work specifications be included in the bid.

In this way, the manager:

  1. requires that accepted tree care practices are followed and,
  2. will be able to judge bids from different companies in a fair manner, based on comparable work specifications.

Why train employees to use and understand A300 standards?

Some clients desire a lot of information about how their trees are cared for. To see how the A300 Standards relate to what a typical client wants to know about tree pruning, please visit TreeCareTips.org.

Incorporating A300 into your operations and your thinking makes good business sense. Increasingly, contracts for governmental, institutional and large commercial projects are specifying that tree care maintenance shall be performed according to the ANSI A300 Standards. There is another benefit of A300: crew training.

Remember the first time you climbed a tree to prune it? If you were like most green climbers, you got into the tree and thought, “What am I doing?” After you climbed for a while, you developed a methodology: You sized up the tree from the ground, chose your tie-in points and figured out where most of the work was. Then you climbed to the top of the tree and tied in.

At that point, if you were like most arborists, you started to eliminate the most obvious problems first, then evaluated what was left. With A300, the arborists you train will be better able to focus on and prioritize what they are doing. For instance, if the tree is to be cleaned and the new climber understands what that means according to ANSI A300 Pruning standards, then the work can be done properly. The clarity of communication between the tree owner, the sales representative, and the arborist is tremendous.

How can I train my employees to write pruning specs?
