Advanced Tree Risk Assessment
Advanced, or Level 3, assessments provide detailed information about specific tree parts, defects, targets, or site conditions. Tree assessments performed at this level are usually time intensive and more expensive to conduct, as they require specialized tools and/or skills. Advanced assessments usually are reserved for high-value trees or trees of historical importance. Level 3 assessments can include, but are not limited to:
· aerial crown inspections
· internal decay inspections
· subsurface root inspections
The Air Spade is an excavation device that uses compressed air to remove soil. It's powerful enough to handle heavy materials like hard clay or clumps of soil. At the same time, it's gentle enough to safely use around sensitive roots.
