Includes additionl literature. Published by the UF School of Forest Resources and Conservation, July 2010.

Eight years of post-storm tree maintenance records from Rochester, New York, U.S., were reviewed ... more Eight years of post-storm tree maintenance records from Rochester, New York, U.S., were reviewed to evaluate the city's storm-related removal protocol and how maintenance varied by damage classes. Maintenance codes assigned in 1991 were used to identify ice-storm damage classes based on percentage of crown loss. We evaluated seven species-Noway maple (Acer platanoides), silver maple (A. saccharinurn), sugar maple (A. saccharurn), green ash (Fraxinus pennsylvanica), honeylocust (Gleditsia triacanthos), London planetree (Platanus x acerijolia), and littleleaf linden (Tilia cordata)-to assess species responses to maintenance protocols. Trees with 75% or more crown loss and undamaged trees required the least amount of maintenance, additional management, and on-site re-evaluation. In contrast, trees with 50% to 75% crown loss required the most maintenance, were the greatest percentage of trees requiring additional maintenance, and were the most revisited. Of the selected species , analyzed, silver maple and honeylocust required the most maintenance, whereas sugar maple, green ash, and 1ittleleaElinden required the least. Across all damage classes and species, maintenance requirements increased with tree diameter at breast height regardless of the percentage of crown loss or species.

Maintenance codes assigned in 1991 were used to identify ice-storm damage classes based on percentage of crown loss. We evaluated seven speciesNorway maple (Acer platanoides), silver maple (A. saccharinum), sugar maple (A. saccharum), green ash (Fraxinus pennsylvanica), honeylocust (Gleditsia triacanthos), London planetree (Platanus ´ acerifolia), and littleleaf linden (Tilia cordata)to assess species responses to maintenance protocols. Trees with 75% or more crown loss and undamaged trees required the least amount of maintenance, additional management, and on-site re-evaluation. In contrast, trees with 50% to 75% crown loss required the most maintenance, were the greatest percentage of trees requiring additional maintenance, and were the most revisited.

Fertilized trees displayed nonsignificant shoot growth and leaf color when compared to nonfertilized ones. Neither fertilizer type, nor rate of application appeared to affect wound closure rates over the two year measurement period. This study showed increased replication will be needed when studying landscape trees, since trends in known primary growth response to fertilization were present but were not statistically significant. Fertilization effects on secondary growth including diameter increase and wound closure rate, were correspondingly not significant. Secondary growth responses may be difficult to demonstrate in live oak when using landscape trees especially at lower nitrogen rates currently being recommended in the industry.

Decay was determined by drilling sampled trees with a Resistograph and calculating the ratio of sound wood to radius. Overall, 58.3% of the sampled trees had some amount of decay and incidence was highest in sugar maples and in the largest size class trees. However, decay incidence was high (53.2%) even in the smallest diameter tree size class (30.5–45.7cm (12–18 in). Decay severity was greatest in silver maple and in the largest diameter trees, although only 3.2% of the trees sampled had serious decay. The study shows that decay is common in street trees but is seldom severe. It also suggests that decay becomes established early in the life of street trees but is most severe in larger diameter trees and in trees that compartmentalize deca...
