Services
Tree Disease Diagnosis
Our diagnostic process combines tree physiology knowledge with 40+ years of Boulder-specific experience to identify diseases early. We examine fungal infections, bacterial issues, and structural weaknesses, providing actionable treatment plans. Early detection prevents irreversible damage through the tree's natural defense mechanisms.
Tree Risk Assessment
We analyze structural defects like decay and root problems to predict failure risks. Our assessments consider location factors and species characteristics, offering mitigation strategies that balance safety with tree preservation. Stef's teaching background ensures thorough, understandable reports.
Tree Appraisals
Using Council of Tree and Landscape Appraisers guidelines, we calculate tree value based on size, species, health, and location factors. Our 30+ years of appraisal experience helps clients with insurance claims or legal disputes involving damaged or destroyed trees.
Wildfire Risk Mitigation
We develop defensible space plans that reduce ember threats without clear-cutting forests. Our approach maintains aesthetic value while creating safety zones around structures, based on Boulder's wildfire patterns and Stef's published research opposing over-thinning.
Plant Health Care
Monthly growing-season inspections identify potential issues early. We provide customized watering, pruning, and pest control recommendations for Boulder's climate, combining scientific knowledge with practical solutions for residential and commercial properties.
