Abstract: The purpose of this study was to determine if there are different earthworm abundances in
different soil or forest cover types at Colonial Point in Cheboygan County, MI. Vegetation, soil, and
worm data were collected from several locations that were randomly selected among an area of
Colonial Point with diverse soil and vegetation types. It was found that the dominant forest type and
gross leaf litter weight had no significant effect on worm abundance. Soil type however, did show a
significant difference in earthworm abundance between sand and clay soils. A moderate trend was also
found positively correlating earthworm abundance and pH. This suggests that earthworms prefer mesic
soils with favorable moisture and nutrient conditions. This information can be important in attempting
to efficiently prevent the spread of invasive earthworms in the future.
