Jay Dampier Adds Tree Diagnostics as Urban Forestry Today 2023 Webinar

Summary: Jay Dampier adds Tree Diagnostics as Urban Forestry Today 2023 Webinar to International Society of Arboriculture Continuing Education Unit offerings.

Jay Dampier adds Tree Diagnostics: Tips for Success as the first Urban Forestry Today 2023 Webinar to the International Society of Arboriculture Continuing Education Unit (CEU) offerings approved for the New Year.

Dr. Dampier, as Extension professional based at the University of Wisconsin in Madison, Wisconsin, broaches five steps, two tips and three examples in his hour-long broadcast. The content communicated Thursday, Jan. 12, 2023, between 11:00 a.m. and noon Wisconsin Time, concerns five steps even as it concentrates on steps 3 and 4. Developing the best strategy defers to determining the correct diagnosis, which depends on deriving the correct identification of the damaged, declining or dying plant in question.

The second step entails the exact identification of the problem evidenced or experienced by the plant endangered or enfeebled by abiotic, non-living or biotic, living causes.

Symptoms, signs and damages furnish respective indicators, such as dieback, of function failure; visible consequences, such as honey-mushroomed roots; and perpetration such as animal-scatted, animal-ravaged trunks.

The third step about gathering information gauges the plant, the environment, the plant and the area histories and the gardening maintenance practices that govern plant growth. The fourth step heralds researching potential diagnoses from which tree diagnosticians harvest the fifth step’s finding management options that heal the plant and hinder the harm. The third and the fourth steps invite in-depth inspection through the interview-question iterations that Dr. Dampier includes in his tree-diagnosis instructions and on go.wisc.edu online inclusions.

The first Urban Forestry Today 2023 Webinar joins Tree Diagnostics: Tips for Success by Jay Dampier to equivalent tips in all Urban Forestry Today webinars, 2016-2022.

Dutch Post-Impressionist painter Vincent van Gogh (March 30, 1853-July 29, 1890), through his accurately artful, artfully accurate roots and trunks, allows tree diagnosticians to attempt the five steps and the two tips that Jay Dampier, as Statewide Outreach Program Manager of the Horticulture Program at the University of Wisconsin-Madison Division of Extension, articulates in Tree Diagnostics: Tips for Success, first Urban Forestry Today 2023 Webinar in the series available thanks to Dr. Rick Harper of the University of Massachusetts Extension at Amherst, Massachusetts; Public Domain, via Wikimedia Commons

Plant background kindles knowing illness timespans, partial or plant-wide effects, dry or wet planting areas, area construction and different- and same-species plants nearby with similar symptoms.

Plant site logs soil type, mulch depth and type, sunlit hours, low-lying or sloping areas, dry or wet areas, site descriptions, area roads/sidewalks, fans/vents and construction. Plant history monitors watering, pruning and fertilization; herbicide and pesticide exposure and use; different- and same-specied surrounding plants similarly symptomatic; and first timings of symptomatic occurrences. Dr. Dampier notes that the research needed for all five steps necessitates that diagnosticians net, as with book and journal sources, research-based and unbiased internet sources.

The first Urban Forestry Today 2023 Webinar, Tree Diagnostics: Tips for Success by Jay Dampier, offers two tips that optimally organize obtaining research-based, unbiased internet-sourced research.

Jay Dampier of the University of Wisconsin-Madison Division of Extension arranges internet domains .edu and .gov, .org and .com from respectively trustworthiest to potentially trustworthy to trustworthiness requiring verification; GitHub cisagov (CISA Cybersecurity and Infrastructure Security Agency) dot gov (DotGov program) graphic of logo for domain name .gov uploaded Friday, Aug. 20, 2021, 12:42, by Hmftwiki via UploadWizard: Public Domain, via Wikimedia Commons

The first tip pertains to placing the word “extension” or putting the domain “.edu” at the end of the search terms positioned in the search box.

The domains .edu and .gov quarter the trustworthiest sources even as the .org and the .com domains respectively qualify as potentially trustworthy and sources requiring verification. The second tip reaps diagnostic area-appropriate resources since, for example, Minnesota northeastward through New York northward to Maine plant backgrounds, sites and histories resemble one another. The three examples that Dr. Dampier shares in staging all five steps and both tips suggest cherry black knot, red maple girdling roots and boxwood blight.
