December 2024 Arborist News Apprises Us of Tree Inventory BMP Part I

Summary: Co-authors Wiseman, Endahl, Christensen apprise us of Tree Inventory BMP: Planning a Successful Tree Inventory, Part I in the December 2024 Arborist News.

"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.

A tree inventory most appropriately anteceded the pruning activities in the above image. One year's urban forest-managing budget perhaps applied funds to such a tree inventory that approached pruning activity as the appropriate action for tree or tree-part damage, danger or decline. Another year's urban forest-managing budget perhaps approved post-inventory action upon inventory-articulated tree-management actions. Such costs often are not articulatable until after the actual inventory and therefore perhaps beyond current-budget means; "Arborist prunning tree near Statue of Liberty, New York.

Associate Professor P. Eric Wiseman, Consulting Advisor Jordan Endahl, Certified Arborist Brittany Christensen apprise us of Tree Inventory BMP: Planning a Successful Tree Inventory, Part I in the December 2024 Arborist News.

Tree-inventory best-management practices bring together one associate professor and two Master graduates of Virginia Polytechnic Institute and State University Department of Forest Resources and Environmental Conservation. The tree-inventory systematic process and its produced report collect area-of-interest (AOI) frequency- and coverage-categorized, geographic area-concentrated location-, quantity-, characteristics-concerned data for urban-forest planning, management, conservation purposes. The pre-inventory planning process’s first-step needs assessment, done with key stakeholders, perhaps with external consultants and the surrounding community, defines budget; goals; key personnel; objectives; resources.

Periodic versus continuous tree-inventory frequency effectuates urban-forest data-collecting over discrete timelines such as tree mortality every three years, versus steadily, such as tree-maintenance activities each workday.

Complete versus partial versus sample tree-inventory coverage features data-collecting about every area-of-interest (AOI) tree versus every AOI tree fitting certain inclusion criteria versus random-selected AOI trees.

Broad-themed goals guard what generates frequency- and coverage-type inventories even as community needs and resources guide, albeit variably, how frequency- and coverage-type inventories gain their goals. Most inventories have population-counting and locating key objectives for work-planning, budget-preparing, policy-developing, program-reviewing urban-forest extent, structure, health; and for Tree Risk Assessment Qualified (TRAQ) risk-assessing data-collecting. Inventory-tracked work histories indicate individual-site and population change-impacted service requests, crew productivity, individual-tree or tree-group useful-life end, species-performance evaluation and urban-densification crown-reduction pruning and other needs.

Tree inventory BMP, Part I jubilates population-size and characteristics determination, tree-risk management, maintenance-needs determination, work-history record objectives; investment-justifying environmental-benefit estimates; tree-equity assessment; site development; tree-value appraisal.

Urban-forest managers know demographically, socioeconomically disparate distribution from distributional-equity inventories even as preconstruction inventories know high-value trees, construction-kindled, post-construction-removable trees, postconstruction tree-management recommendations and tree-protection planning.

Appraisal-value inventories, like every tree inventory, lodge key-field, key-office personnel, perhaps consultant-, contractor-, volunteer partners, the lattermost lambasted as lackluster-trained, lamentable without supervision, low-cost subpar-data loggers. Knowledgeable, trained tree-inventory data-collecting may motivate such credentials as International Society of Arboriculture (ISA) Certified Arborist, risk-managing Tree Risk Assessment Qualification (TRAQ) and perhaps municipality-mandated credentials. Goals-, objectives-, personnel-notified urban-forest managers nestle inventory budget resources into data-collecting, managing, maintaining and, new management-funded activity not known until post-inventory, next-budget funded, post-inventory tree-management recommendations-implementing.

The article Tree Inventory BMP observes in Planning a Successful Tree Inventory, Part I, inventories occasioning personnel; data-collection hardware; data-collection software; data-ownership, subscription, update ongoing costs.

Communications-technology pencil, paper; GIS Geographic Information, GPS Global Positioning Systems-provisioned data-loggered, smart-phoned, tableted handheld computers; crown tree crown-, diameter-, height-providing light-detection-and-ranging (LIDAR) technology populate data-collecting hardware.

Attribute customization; consistent-format data-recording drop-down lists; data export or integration; GPS integration; location-reviewing, inaccuracy-adjusting map view; offline data collection; and photo collection qualify as data-collection software. Inventory-data ownership and data-use respect vendor-relationship changes even as such readjustments sometimes require urban forest-managing agencies purchasing more software or reacting to vendor and/or vendor-software retirement. GPS or dedicated-tree inventory-management systems suggest software-sustaining ongoing subscription fees such as periodic payments to support tool access and vendor Software as a Service (SaaS) acceptance.

Tree Inventory BMP tallies, in Planning a Successful Tree Inventory, Part I, total tree-inventory conducting and maintaining costs by treating high-priority areas or predetermined inspection cycles.

All tree inventories aspire, in support of broad-themed goals, to such actionable-, specific-target objectives as maintenance needs, site construction- and development-managed trees, tree equity, tree risk, tree-appraisal value, tree-population size- and characteristics and work history. They aspire to such budgeted resources as field and office, partnered consulting and contracting and volunteer key personnel; data-collection hardware and software; and data-ownership, subscription and update ongoing costs. Data-collection hardware assumes its most accessible equipment in communications-technology paper and pen and its most advanced in light-detection-and-ranging (LIDAR) technology. The latter assures us of crown-spread, tree-height, trunk-diameter measurements more accurate than with such manual means as paper-and-pencil technology. It nevertheless avows nothing for plant health-care recommendations or tree-risk ratings; "A typical workflow to derive forest information at individual tree or plot levels from lidar point clouds," Monday, Feb. 5, 2018, graphic uploaded via UploadWizard Monday, June 19, 2023, 01:34: Bnurs, CC BY SA 4.0 International, via Wikimedia Commons
