UNC campus can be considered an arboretum as the campus holds some very unique trees and over the years some of our trees have boasted State Champion status.
We strive for a diverse population of trees and ornamental plantings, in order to assist in educating the UNC community of proper plant selection and arrangement in the landscape.
One of our goals is to promote plant health by performing proper maintenance practices that include proper watering, fertilization, pesticide application and pruning, as well as to serve as the standard for professional horticultural practices for the Greeley community at large.
It is also our goal to preserve our campus heritage by encouraging tree protection prior to and during construction.
Pruning and Removals
Currently, UNC is completing a 5-year high risk tree assessment. This has comprised mostly of the campus perimeter street trees. This evaluation included 119 removals and complete pruning of over 700 trees. The older Central Campus and its respective largest and oldest trees were targeted first, as the older trees pose the greatest risk. The next 5-year (2008-2013) evaluation will include the trees on the West Campus and the University Center. After this 5-year period, tree assessments will rotate back to the Central Campus. The overall impact of hazardous tree evaluation program is to make our campus safer, promote tree health and minimize tree failures due to high winds and other severe weather impacts.
Tree removals are submitted for approval through the Assistant Vice President of Facilities Management and tree removals within the City of Greeley Right-of-Way, are subject to approval by the City of Greeley, Division of Forestry.
Pruning priorities are based on high risk trees that pose the greatest risk to human life and property damage. High risk trees are determined with use of the Hazardous Tree Evaluation guidelines. For further information, regarding tree evaluation and resources, visit Trees Are Good.
Pesticide Applications / Ips Engraver Beetle
UNC continues the constant battle against Ips Engraver Beetle that attacks the older population of our Heritage Blue Spruce trees. Some of these giants are nearly 100 years old. A contractor applies an insecticide (Astro) during the Spring Break Period. Faculty and staff are notified via email of the proposed application schedule. A diverse landscape promotes a healthy campus by discouraging insect infestations disease.
Natural Disaster Planning
Supplemental to the University’s Emergency Response Plan, a Preparedness Checklist is included to address catastrophic tree losses on the university campus and the adjacent community. It is only a checklist to ensure that the necessary steps are taken to mitigate such losses.
UNC enforces the Landscape Preservation Policy measures prior to and during construction, in order to follow standards for the preservation of specimen trees, ornamental plantings, and historically significant trees and landscape plantings on campus.
