The first ANSI Standard for tree care was developed in 1991. Since then our industry has developed eleven different standards in regard to tree care. In July, updates to both the Pruning (A300 Part 1) and the Tree Risk Assessment (A300 Part 9) standards were released.
There are several very significant changes to the Pruning standard. Removed from the standard was clause 6.1.4 “Not more than 25 percent of the foliage should be removed within an annual growing season…” Yes, you heard that right. No more will we be following the ambiguous 25% rule. But wait, there’s more. The Methods, or Types, of pruning have been eliminated. Crown raising, thinning, cleaning, reducing, etc. are no longer defined terms within the standard. These have been removed in favor of a “Systems” approach to pruning, or as the new revision states: “A pruning system should be specified to achieve the desired long-term form of the plant.” Read More "ANSI Pruning Standard Updated"
It all began in 1992, in the Pacific Northwest Chapter, when 13 hardy souls decided they could raise money for trees by riding their bicycles from Seattle to San Francisco in eleven days. The inaugural ride was 1,050 miles. The riders averaged over 100 miles a day with the longest day being 144 miles. The first Tour des Trees exceeded their goal of $60K by raising nearly $100K. Twenty-five years later the Tour is still going strong. This year’s riders traveled a mere 578 miles in seven days and raised over $300K for tree research and education. In 25 years the Tour des Trees has raised more than $3 million dollars and riders have pedaled nearly 15 thousand miles, all in the name of tree research and education. Not too bad for a bunch of tree hugging cyclists! Read More "Tour des Trees – 25-year Silver Anniversary"
This is the third, and likely the final, article on Pristophora geniculata, Order Hymenoptera, identified consuming up to 90% of the foliage of certain Mountain Ash trees in Metro Vancouver, BC in 2015, with subsequent defoliation in summers of 2016, 2017. This chewing insect pest was previously reported in Ontario after 1938, of European origin, and never reported west of Michigan. This pest has a complete life cycle and, once established, does not have to move far from the host plant, exclusively in the genus Sorbus. There are 100 to 200 species within this genus worldwide. Of particular interest to arborists are ornamental Mountain Ash trees in gardens and public landscapes. Read More "Mountain Ash Sawfly Larvae Eat Their Way Into Year Three"
OLYMPIA – The Washington Invasive Species Council and a consortium of agencies and universities are asking residents to check trees and swimming pools in their yards for harmful bugs as part of the national Tree Check Month in August.
August is the peak time of year to find invasive bugs like citrus longhorned beetles, emerald ash borers and other aggressive wood-boring insects. Trees near your home and in your neighborhood, the “urban forest,” are as susceptible as trees in rural and wild forests, sometimes even more so due to the stresses of urban life.
