  Leaf Phenology of Callery Pear: Fall

  Margaret E. Maloney, Abby Hay, Eric B. Borth, and Ryan W. McEwan

  This dataset is one of three affiliated with the paper "Leaf phenology and freeze tolerance of the invasive tree Pyrus calleryana Roseaceae) and potential native competitors."

  The other two datasets are:

  • Leaf Phenology of Callery Pear: Spring
  • Leaf Phenology of Callery Pear: Frost Damage

  Data from Callery Pear Prairie Survey

  Michaela J. Woods, Grace Dietsch, and Ryan W. McEwan

  This dataset was curated following the examination of two prairies invaded by Callery pear, and two that were not invaded. We assessed soil nutrients and chemistry, plant cover, and proximity to different land uses to see if they impacted Callery pear abundance, presence/absence or cover.

  Callery Pear Removal Experiment: Trees-Intact (Medlar Conservation Area)

  Margaret E. Maloney, Eric B. Borth, Grace Dietsch, Mary C. Lloyd, and Ryan W. McEwan

  The invasive tree Callery pear (Pyrus calleryana) is problematic in open habitats in the American Midwest. We investigated the efficacy of various control techniques on P. calleryana invasion in grasslands. Treatments were applied to P. calleryana stems that were single-stemmed trees (around 7 years; n = 40 stems), and response of those stems was measured.

  Callery Pear Removal Experiment: Trees-Sprouting (Stillwater Conservation Area)

  Margaret E. Maloney, Eric B. Borth, Grace Dietsch, Mary C. Lloyd, and Ryan W. McEwan

  The invasive tree Callery pear (Pyrus calleryana) is problematic in open habitats in the American Midwest. We investigated the efficacy of various control techniques on P. calleryana invasion in grasslands. Treatments were applied to P. calleryana stems that had experienced mowing annually for several years and were sprouting (n = 100 stems) and response of those stems was measured.

  Seedling growth and soil chemistry in a chronosequence of forest restoration from agriculture

  Michaela J. Woods, Sarah J. Frankenberg, Joseph R. Juodvalkis, Mary C. Lloyd, Meredith Cobb, and Ryan McEwan

  Soils were collected from forest restorations that were 0, 7, 10, 50 and 100 years old and assessed for soil nutrients, chemistry, and enzymatic activity. Quercus macrocarpa seedlings were planted in each soil type, after 5 months of growth seedlings were destructively harvested. Seedling mass and the colonization rate of their roots by ectomycorrhizal fungi are reported.

  The photo accompanying this data collection is of the researchers' germinating Quercus macrocarpa seeds.

  Soil Chemistry and Enzyme Data Examining Impacts of Callery Pear Stem Cutting

  Michaela J. Woods, Grace K. Attea, and Ryan W. McEwan

  This dataset encompasses information following the collection of soil from underneath cut and treated Callery pear stems and untreated Callery pear trees. Soil was assessed for moisture, pH, and enzyme activities.

  Seed Size and Germination

  Meredith Cobb, Michaela J. Woods, and Ryan W. McEwan

  This dataset encompasses information related to predictors of seed germination from the species Carya laciniosa, Juglans cinerea, and Quercus rubra. Seed sizes were recorded prior to incubation in sand, vermiculite, or without media. Seeds were then germinated with time to germination recorded in this dataset.

  Seed and Seedling Data from Sugarcreek Metropark Restoration Experiment

  Michaela J. Woods, Meredith Cobb, and Ryan W. McEwan

  This dataset encompasses information following seed germination and seedling growth of three tree species: Quercus rubra, Juglans cinerea, and Carya laciniosa. Seed sizes were recorded prior to incubation in sand, vermiculite, or without media. Seeds were then germinated with time to germination recorded in this dataset. After germination, seedlings were planted in Sugarcreek Metropark in either fall 2011 or spring 2012. One-half of seedlings were planted in tree tubes and a half without. Seedling height and diameter was recorded in June 2014 and March 2019, and death of seedlings was noted.
