Article Figures & Data

Figures

  • Figure 1.
    Figure 1.

    Cumulative number of pruned and unpruned trees in the City of Rochester, New York, in the period between 1992 and 1999. Trees that were in management areas that had been pruned for longer than 5 years were returned to the unpruned pool of trees.

  • Figure 2.
    Figure 2.

    Number of forestry-related service requests in pruned and unpruned management areas in the City of Rochester, New York, in the period between 1992 and 1999. LSD on the average of pruned (31.6 requests per 1,000 trees) and unpruned (39.4 requests per 1,000 trees) management areas = 7.4; P = 0.05.

  • Figure 3.
    Figure 3.

    Number of pruning-related service requests in pruned and unpruned management areas in the City of Rochester, New York, in the period between 1992 and 1999. LSD on the average of pruned (16.8 requests per 1,000 trees) and unpruned (23.4 requests per 1,000 trees) management areas = 6.4; P = 0.05.

  • Figure 4.
    Figure 4.

    Total branch-failure-related service requests for all trees in the City of Rochester, New York, in the period between 1992 and 1999. There was no significant difference between pruned and unpruned management areas; therefore, the data were combined.

  • Figure 5.
    Figure 5.

    Branch-failure-related service requests one week after high-wind events in pruned and unpruned management areas in the City of Rochester, New York.

  • Figure 6.
    Figure 6.

    Branch failure work completed in the leaf-on and leaf-off period in the City of Rochester, New York, from 1992 through 1999. Leaf-on period ran from May 16 to November 15. LSD on the average number of visits in the leaf-on period (176.7 visits) and leaf-off branch failure work completed (60.0 visits) = 94.5; P = 0.05.

  • Figure 7.
    Figure 7.

    Priority maintenance work in pruned and unpruned management areas in the City of Rochester, New York, in the period from 1992 through 1999. Priority maintenance work is safety pruning that was identified based on annual survey work in the city. Yearly numbers are the average of priority visits in the years prior to and post-pruning. LSD between average annual priority pruning prior to (102.8 priority pruning) and post-pruning (45.3 priority pruning) = 36.8; P = 0.05.
