Kristopher Rasmussen, CTSP, QT, Arborist Strong
This session examines the ANSI A300–2023 pruning standards and their role as the foundation for work specifications, training programs, quality assurance protocols, and regulatory guidance for managing trees, shrubs, palms, and other woody landscape plants. Participants will learn the essential components required for pruning specifications to meet A300–2023 standards and why precise, objective-based language is critical to consistent and defensible tree care.
It will explore industry Best Management Practices (BMPs) and the Prescriptive Pruning Qualification (PPQ) as practical tools for clearly defining how a tree, shrub, or palm is to be pruned. Emphasis is placed on developing effective pruning prescriptions that begin with understanding the client’s concerns and the plant’s condition, then assigning clear, measurable objectives that directly address those concerns.
Participants will gain insight into how well-written pruning prescriptions – those that specify which branches are to be pruned, the number of cuts, maximum cut size, and exact cut locations – improve communication among clients, sales arborists, and production arborists. While pruning objectives may differ between young, establishing trees and mature trees, the prescription-driven process remains consistent across all life stages.
