Earth and Space News: Tree Risk Assessment Admits Best Management Practices Abbreviated BMPs

Summary: Tree risk assessment admits Best Management Practices BMPs, in Tree Risk Assessment BMP: Context, Concepts, and Considerations in Arborist News April 2024.

"God talks to human beings through many vectors: through each other, through organized religion, through the great books of those religions, through wise people, through art and music and literature and poetry, but nowhere with such detail and grace and color and joy as through creation. When we destroy a species, when we destroy a special place, we're diminishing our capacity to sense the divine, understand who God is and what our own potential is." Robert Francis Kennedy Jr., April 19, 2023, Boston Park Plaza Hotel, Back Bay, Boston, Massachusetts.

“And there’s many people out there who want us to move to the next planet already and I’m like, hang on, let’s not give up on this planet yet," William, Prince of Wales, July 31, 2023, Sorted Food food truck, London, England, United Kingdom.

Limited information about immediate environments, site usage, structural conditions, targets and the latters’ occupancy rates as well as uncertainty about biological processes such as decay progression rates and response growth, occupancy rates, potential consequences of tree failure, soil conditions and weather events accompany tree risk assessments. Tree risk assessment as accurate as possible accords with assessing “the combination of each failure type and target as an independent event” and stating “clearly what risk(s) are rated” (Smiley:11). The tree removal in the above image accords with water conservation even as it acknowledges likelihoods of building-ward branch and whole-tree failures respectively against the building roof and the building façade; Tuesday, Feb. 5, 2008, 09:07, United States Marine Corps image of tree removal from commanding general's building, Pendleton Hall, as part of plan, combined with artificial turf replacement of grass, for annual water savings of 357 gallons at Marine Corps Base Camp Pendleton, San Diego County, Southern California: Public Domain, via Wikimedia Commons

Tree risk assessment admits Best Management Practices BMPs, in Tree Risk Assessment BMP by E. Thomas Smiley, Nelda Matheny, Sharon Lilly, Brian Kane, Ryan Klein, Beth Brantley in Arborist News April 2024.

The six co-authors base their article around tree failure rarely bringing about “serious damage, injury, or death” (Smiley:10) and upon 2024-revised International Society of Arboriculture BMPs. Tree risk managers consider specific conditions and situations that consequently compel them to configure reasonable tree risk assessment levels or not to configure them at all. Tree risk assessments defer to their purpose of developing risk-identified, risk-analyzed information for tree risk managers to decide tree or tree-property management advanced assessment, mitigation, reassessment.

Tree inspections entail arborists visually observing tree form, health and structure, per their information-gathering purpose, to ease pruning, removal, structural-support, lightning-protection, pest-management, soil-remediation, tree-care, tree-management decisions.

Worksite inspections, per site-and tree-condition purposes facilitating work scope, safety and procedures, figures tree workers visually observing tree and work areas before and during work operations.

Uncertainty goes with tree risk assessment limitedly predicting such biological processes as decay-progressing rates and response growth; occupancy; potential tree-failure consequences; soil conditions; and weather events. International Society of Arboriculture-honed tree-risk matrices’ failure likelihood, impact likelihood and failure consequences harken risk ratings hinging upon each failure type, each target as independent events. Tree risk managers importantize risk-mitigation prioritization and, as highest risk rating and, for limited visual assessments and tree populations, single risk level, overall tree risk rating.

Best management practices BMPs in tree risk assessment judge as moderate overall risk rating respectively low and moderate likelihoods of target-impacting whole-tree and dead-branch failures respectively.

The previous example kindles moderate tree risk rating as higher of two low- and moderate-risk ratings even as trees with highest-risk mitigations sometimes know residual risk.

Reliable tree risk assessment logs failure-, impact-, consequences-rated consistency by knowledgeable, trained tree risk assessors even as assessor subjectivity and condition uncertainty limit complete assessor consistency. Condition uncertainty means that environmental conditions such as wind loads, decay- or defect-lowered load-bearing capacity, specific targets and target zone occupancy militate against their precise measuring. Tree assessors’ educational background, personal risk tolerance and work experience nurture assessor subjectivity even as subjectivity management necessitates their training in defining and calibrating ratings categories.

Best management practices BMPs typically obtain from majority versus smaller versus rare proportions of urban populations respectively low-, moderate-, high-rated tree risk in tree risk assessments.

Uncertain tree load-bearing capacities and tree-load experiences, despite wood-condition advanced determination techniques, despite tree-area wind-speed precise measurements, prevent tree risk assessors presenting certain failure likelihood assessments.

Uncertain directions of tree fall and uncertain estimates of pedestrian and vehicle tree-area numbers targetable by tree failure quicken uncertain tree risk assessments of impact likelihoods. Best management practices BMPs recommend that tree risk assessors reveal in risk assessment reports such limitations as assessment methodology and tree site or potential target access. They likewise say that tree risk assessors should state in tree risk assessment reports only such specifics as specified, significant-known targets and reasonable-detected, visible tree conditions.

Best management practices BMPs transmit risk categorization timelines in tree risk assessment reports even as they tender no time frames as risk assessment “guarantee period” (Smiley:13).

Tree risk assessment aims at “consistent risk assessment methodology by similarly trained assessors” (Smiley:12). It analyzes tree-failure and target-impact likelihoods in, and their consequences for, ambiances where “inherent uncertainty and subjectivity” (Smiley:12) and limited information audaciously arrange themselves. What tree risk assessment non-unanimously, semi-unanimously, unanimously arises about a woody plant, such as the plane tree (Platanus orientalis) in the above image, assailed by 239 years of non-predictable, predictable site, structure and weather and avowing as its one predictable given no pruning then, now, ever?; Sunday, May 9, 2010, 16:01, image of never-pruned Oriental plane tree (Platanus orientalis), planted by Georges-Louis Leclerc, Comte de Buffon (Sep. 7, 1707-April 16, 1788). in 1785 in the Jardin des Plantes, 5e arrondissement de Paris (5th arrondissement of Paris), rive gauche de la Seine (Seine's left bank), Paris, Île-de-France region, north central France: Jebulon, CC BY SA 3.0 Unported, via Wikimedia Commons
