| In 1954, the Conference undertook a major project
to produce a film titled Trees and Their Care. Time-lapse color photography had
reached a new high in technology, and the observations of plants as they grow
became very popular. ISA began a seven-year campaign to raise twenty-five
thousand dollars for the project. Produced by prominent nature photographer
John Ott of Chicago, the film was shown for the first time at the ISTC’s 1961
annual meeting in Minneapolis. For the professional efforts in producing a film
of such high quality and value to arboriculture, the ISTC received an Award of
Merit from the American Horticultural Council.

In 1957, Shade Tree Evaluation was published under the direction of
Norman Armstrong. For the first time, the Conference was able to provide a
sound basis for evaluating trees. This publication has been revised and updated
eight times, and in 1992 the title was changed to Guide for Plant Appraisal.
The Council of Tree and Landscape Appraisers (CTLA) authored later revisions.
The Guide for Plant Appraisal is one of ISA’s flagship publications.
