Earthworm biomass, soil temperature, bulk density, organic matter, pH, and leaf litter data from jumping worm and European earthworm-invaded forests at the Minnesota Landscape Arboretum, 2020–2022

This dataset accompanies a study on the invasion of Asian jumping worms (Amynthas spp.) into hardwood forests previously infested with European earthworms (Lumbricus spp.) at the Minnesota Landscape Arboretum. The manuscript is current in revision (Baumann, T.T., Frelich, L., Buchholz, E., Wang, S., and Yoo, K. Jumping worm invasion in a European earthworm-infested hardwood forest in Minnesota: population surveys and soil changes. Ecosphere. In Revision.) The dataset includes: (1) earthworm population surveys identifying species composition and biomass across three sugar maple forests, with sampling points classified as Amynthas-dominated (A-sites), Lumbricus-dominated (L-sites), or transitional (T-sites); (2) soil physical and chemical properties including bulk density, soil organic matter, and pH measured at three depth intervals (0-5, 5-10, 10-15 cm); (3) seasonal leaf litter dry mass measurements; (4) continuous soil temperature records from iButton sensors at multiple depths; and (5) GPS coordinates for all sampling locations. Data were collected during 2020-2022.
