GRANVILLE, OHIO (April 5, 2021) The Licking Park District actively supports research that informs the management of our natural resources. Invasive species, and the detrimental impact they have on native species, are of particular concern. In 2020, The Ohio State University graduate student Krystal Pocock collected native crayfish from Lobdell Reserve as part of a larger project examining differences in leaf consumption by crayfish in Ohio. Crayfish are important to stream systems as they break down nutrient rich, coarse leaf litter. However, research has suggested streams with non-native crayfish have accelerated leaf litter breakdown and reduced standing leaf litter. This reduces available habitat and food for fish and aquatic macroinvertebrates and may lead to reduced biodiversity.
