Building upon earlier work using urban tree inventories, this project seeks to put an urban context into the management approaches of forestry. Specifically, the project addresses three linked objectives. One common management task is developing inventory analyses to describe canopy species and age class distributions. In developing management choices, our principal limitations are those of assigning an age estimate to the measured size developed in field inventories, and designating over-maturity, or when to begin thoughts of proactive transitions in canopy or community structure. Toward that end, our project moves along three project objectives. Objective 1 develops an age-to-trunk diameter estimator for common urban trees growing in three common tree planting design situations, based on access to soil (pits, strips and lawns). Observations suggest different growth expectations in different design situations, based on trunk size and canopy size measures. We seek to link these measures with age to target growth impacts and service life estimation for better urban tree management organization. We additionally look to discuss over-maturity in the designed landscape. We explore and develop this aspect in risk (root plate architecture of large trees and wind-caused tree wind-throw) as objective 2, and in citizen-based observation and data input for species occurrance (inventory analysis of target species within specific pest infestation zones) as objective 3. Objective 4 specifically targets the development of management tools and methods to address the Emerald Ash Borer, which has arrived in New Jersey and is poised to be a significant disturbance with himpact on municipal tree service life management decisions. .Through these projects, we can develop better context and discussions of canopy transition in the urban and municipal canopy within more standard forestry management constructs.
