Partner Projects: Rock Hill Tree Inventory

Oakhaven Park

The City of Rock Hill has collaborated with Missouri Botanical Garden’s Deer Creek Watershed Alliance to conduct its first comprehensive tree survey of all City of Rock Hill public property. This project will enable City of Rock Hill to create and maintain a public street and park tree inventory and allow them for the first time to develop and implement a strategic tree maintenance plan. The goal of the project is to enhance the quality of life for City of Rock Hill residents and improve water quality in the Deer Creek Watershed.

Rock Hill tree inventory mapThe City of Rock Hill has hired Davey Tree Company, an experienced urban forestry consulting firm to conduct a comprehensive GIS-based inventory of street trees and park trees in seven city-owned parks: Greenwood Park, Hensley Park, Oakhaven Park, Oak Trail, Rock Hill Park, Stroup Fields, and Whitfield Park. The information collected will assist the City of Rock Hill’s staff in its ability to efficiently locate existing trees, prioritize tree maintenance tasks, and identify, assess, and correct storm damaged trees. View the Tree Inventory Summary Report for additional information.  A portion of the funding for this project was made available through the Missouri Department of Conservation’s Tree Resource Improvement and Maintenance (TRIM) Program, and also through the Great Rivers Greenway District.

Rock Hill parks and recreation director, Al Hayden said he was grateful for the assistance from the Botanical Garden’s Deer Creek Watershed Alliance with this project as it will be very beneficial with future tree care and planting strategies. The City of Rock Hill’s vision to promote and preserve the urban forest and improve the management of public trees was a fundamental inspiration for this project. This vision will ensure canopy continuity, which will reduce stormwater runoff and improve air quality, public health, and aesthetic values.

Key Findings:

The structural value (an appraised value based on the size, condition, species, and location of each tree) of the inventoried tree population is approximately $2.28 million.
Rock Hill’s tree population provides approximately $7,260 in the following annual benefits: 
  • Air Quality: 818 pounds of pollutants removed valued at $3,940 per year. 
  • Carbon Dioxide: 10 tons valued at $1,360 per year. 
  • Stormwater: 29,274 cubic feet valued at $1,960 per year.
A total of 972 trees were inventoried, including 831 street trees and 141 park trees. 
The most common species are: Acer rubrum (red maple), 6%; Pyrus calleryana (callery pear), 6%; Quercus rubra (northern red oak), 6%; A. saccharinum (silver maple), 5%; and Cercis canadensis (eastern redbud), 5%. 
The plurality (43%) of the urban forest is in the young, 0–8 inches diameter at breast height (DBH) class. 
The overall condition of the tree population is Good. 
Risk Ratings include: 942 Low Risk trees, 29 Moderate Risk trees, and 1 High Risk trees. There were 0 Extreme Risk trees.
Primary Maintenance recommendations include: 815 Tree Cleans, 127 Young Tree Trains, and 30 Removals.
