Tree protection plan and arborist report software

The site map from a Dendrofile report draft: six trees on a Southeast Portland lot, each with a dashed root protection circle sized to its trunk, two marked for removal, and new protection fences in the yard. Sample data, not a real site. — Sample data, not a real site.

A draft you finish

You stay in charge: Dendrofile drafts, you send. The draft opens in your report template with the parts that are arithmetic and bookkeeping already done, so your time goes to the judgment a client is paying for.

What is in the draft

The tree table. One row per tree: species, trunk diameter, condition and the root protection zone.
The site map. Each tree placed on the site plan, with its root protection zone drawn as a circle.
The protection zones. Worked out from trunk diameter, by the common rule of one foot of radius for each inch of diameter, and drawn to scale so fence lines can be checked against them.

Your template, your words

The draft is written into your report template. Your headings, your standard text and the sentences you have refined over many jobs stay as you wrote them. Dendrofile fills the tables and the map.

For permits and development review

Tree protection plans and arborist reports for development review ask for the same parts every time. Portland-area tree rules come built in. Anywhere else, enter your city's rules on the job and the draft uses them.

What it saves

At Community Forest Solutions a tree report used to take about four hours to write. The first one written with Dendrofile, in August 2026, took 2½ hours. That is one report, written by the practice that built the tool, so treat it as a first result.
