Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Current Methods

  • Soil population monitoring
    Started: 1989-05-01

    Method 2. Soil populations are monitored using fall soil samples with forced emergence to estimate relative populations. Two bulb-planter soil samples are collected in the fall from 2 and 4 m from each of 5 selected sugar maple trees. Injury to foliage is recorded on associated trees.

Past Methods (No longer in use)

  • Adult population monitoring
    Started: 1991-04-01
    Ended: 1991-06-13

    Method 1. Adult population levels are monitored weekly using 4 yellow sticky traps located at 3 feet above ground during flight period (April - June). Damage to sugar maple foliage is assessed using 8 trees.
