Tree Surveys and Inventories

Tree surveys and inventories document existing trees on a site and provide a clear record of species, size, location, and condition. These surveys are used for planning, permitting, property evaluation, and long-term tree management.

Each tree is identified and recorded using consistent, standardized methods to produce accurate and reliable documentation suitable for reference and decision-making.

What A Survey Includes

A typical tree survey or inventory may include:

  • Unique tree identification number or tag

  • Species identification (common and scientific name)

  • Trunk diameter at breast height (DBH)

  • General condition rating based on observable characteristics

  • Location data suitable for site plans and mapping

  • Notes on observable structural or site-related factors, when relevant

How Tree Inventories Are Used

Tree surveys and inventories are commonly used for:

  • Property planning and site changes
  • Tree protection and preservation planning
  • Permit or documentation needs
  • Property evaluation and due diligence
  • Establishing a baseline for long-term tree management
  • Supporting arborist reports and letters

They often serve as the foundation for other arborist services, including tree protection planning and written documentation.

Methodology and Professional Standards

Tree surveys and inventories reflect site conditions as observed at the time of evaluation. Trees are living systems, and conditions may change due to weather, construction activity, maintenance practices, or site disturbance.

Survey scope and data fields are scaled to the site and the trees being documented while remaining aligned with generally accepted arboricultural practices.

Deliverables

Tree surveys and inventories are provided in formats suitable for planning, mapping, and recordkeeping, including tabular inventories and supporting documentation.
