In 2016, ArborPro Inc. completed a data collection tree inventory of approximately 3,500 trees at the University. In 2019 the University had a tree failure on campus and requested that we complete the tree inventory for the entire campus. ArborPro completed the campus tree inventory in 2019, with a total of 6,700 trees. We also completed Tree Risk Assessments on approximately 160 trees. The University has been using our inventory and assessment to remove hazardous trees over the last year. They have been utilizing our tree management software to update maintenance records and keep track of removals and new plantings. The most common species type on campus is the ‘Coast Live Oak.’
A tree inventory is the gathering of accurate information on the health and diversity of a community forest. Tree inventories focus on the attributes of individual trees, as compared to a Forest inventory which seek to assess timber attributes on forest stands.
Drexel University’s Operations and Maintenance Department chose to complete a GPS tree inventory & assessment with the urban forest management firm ArborPro, Inc.

On March 19, 2018, ArborPro, Inc. began operations on a comprehensive GPS inventory of campus trees at Drexel University. ArborPro assigned an ISA Certified Arborist to collect detailed information on the condition, size, species, maintenance recommendations, etc. for all trees on campus. ArborPro inventoried a total of 980 trees over the course of the survey and found that 98.1% of the trees were in good to fair condition. We also found the Drexel University campus forest to be diverse with 66 unique species. The top ten species on the campus are; Thornless Honey Locust, Red Maple, Japanese Flowering Cherry, Sawleaf Zelkova, American Sycamore, Hybrid Elm, Red Oak, Downy Serviceberry, Eastern Dogwood and Eastern Redbud.

In August of 2016, the City of Jacksonville released an RFP to inventory all the city trees under the management of the Public Works Department. The ArborPro team successfully inventoried 27,000 trees in 75 parks.

Eugene Water & Electric Board, founded in 1911, is Oregon’s largest customer-owned utility and provides electricity and water to more than 86,000 homes, business, schools and other customers in Eugene, Oregon. Part of their daily operation includes the remediation of vegetation in the active rights-of-way to prevent fires from contact with live power lines.
ArborPro developed and currently supports a desktop and mobile GIS mapping solution for EWEB’s vegetation management department. ArborPro allows staff to inventory all locations where trees or other vegetation conflicts with overhead power lines. It includes the ability to schedule tree work now or in the future and track customer contact information for field crews. This effort has been ongoing since 2005.
The mobile solution runs on GPS devices and allows multiple utility arborists to collect data and schedule prescribed maintenance in the field. This unit is then synced in the office, and all data goes into a SQL Server database. The desktop solution provides mapping, search, reporting, and visualization of all field collected data. Six staff members at EWEB use this solution on a daily basis for their operations. An ongoing contract to provide 4-hour turnaround on maintenance has been in place since 2010, providing for an enhanced level of support and new features.
In April 2015, the City of Grand Rapids, Michigan awarded their tree inventory project to ArborPro, Inc. The project included a comprehensive city-wide tree inventory including stumps and vacant planting sites. Over the course of a few months, ArborPro, Inc. inventoried over 73,000 trees throughout the City. Lead ArborPro project manager, William Brown kept constant communication with the city arborist, Joe Sulak, providing him weekly updates on the project’s progress. A two-man ArborPro completed this project in less than five months. Following the completion of the project Mr. Sulak sent an email, quoted below, thanking William for his hard work and professionalism throughout the project.
Good Morning Bill,
The way you have structured the Oakhill survey is great. I really appreciate all you have done on this project and the regular updates. The survey has been completed in a professional manner and when I have spot checked data, it has been accurate. We will be presenting the data to the City Commission probably mid-summer.
In September 2015, the City and County of San Francisco awarded ArborPro, Inc. a $350,000 contract to complete a city-wide tree inventory. The initial funds available allowed us to inventory of over 80,000 tree sites. Once our team completed the initial project on schedule, the city amended the agreement to inventory up to 140,000 tree sites. ArborPro utilized a five-man team lead by Project Manager Ken Greby. As with all projects, our team performed the survey on a neighborhood-by-neighborhood basis. After completing each neighborhood, we provided the City of San Francisco with a summary neighborhood report that included i-Tree analysis. ArborPro also provided weekly updates as we progressed through the City. Because this tree survey had been a highly political and community-sensitive project, the City created a website to share these updates with the community.
