Mr. Tree’s Tree Preservation program is built around proactive planning that safeguards mature trees before construction ever begins. Serving Portland and surrounding communities—from Beaverton and Hillsboro to Vancouver, Washington—our ISA‑certified arborists start with a detailed site survey, mapping critical root zones, assessing canopy health, and flagging high‑value or heritage specimens regulated under Portland’s Title 11 Tree Code. We then collaborate with architects, engineers, and contractors to integrate protective measures—such as temporary fencing, low‑impact access routes, and mulch‑lined staging areas—directly into project blueprints, ensuring trees remain safe and compliant throughout every phase of development.

During construction, Mr. Tree’s team conducts routine on‑site monitoring to verify that root zones stay uncompacted, irrigation systems remain functional, and any accidental injuries are promptly mitigated with proper pruning or wound care. For projects requiring excavation near trees, we employ air‑spade trenching and root‑bridging techniques that preserve vital roots while allowing utility installation. All field findings are documented in real time with photo logs and progress reports, giving property owners and builders clear evidence of regulatory adherence and reducing the risk of costly fines or delays.

Post‑construction, our arborists transition to long‑term stewardship, providing soil remediation, deep‑root fertilization, and structural pruning to help trees recover from construction stress and re‑establish optimal growth patterns. Customized maintenance plans outline future inspection intervals, mulching schedules, and pest‑monitoring checkpoints, ensuring each preserved tree remains an asset for decades to come. Whether you’re protecting a 100‑year‑old Douglas‑fir on a downtown renovation or ensuring a new office park meets canopy‑coverage goals, Mr. Tree delivers end‑to‑end Tree Preservation services that protect property value, uphold environmental standards, and keep Portland’s urban forest thriving.
