Areas of Interest

I work on ecological restoration and management practices in relation to hydrologic and water quality benefits. 

Biography

Dr. Lenhart co-authored several widely-used management guides including the Aquatic Organism Passage Handbook for MnDOT (2019) and the Agricultural BMP Handbook for Minnesota (2017) for the Minnesota Department of Agriculture. He has led assessment and design of stream and wetland restoration projects and contributes to hydrologic and water quality monitoring efforts for The Nature Conservancy MN, ND, SD chapter. Chris has coordinated the professional restoration certification program for the Society of Ecological Restoration International and serves as president of the SER-Midwest-Great Lakes Chapter. He currently lives with his family in Roseville, Minnesota near Lake McCarrons. Originally from Defiance, Ohio, he has been involved with restoration, management and research related to wetlands and water quality in that region.

Ask me about the Certified Ecological Restoration Practitioner-in-training program (CERPIT). Our Environmental and Ecological Engineering Specialization is aligned with CERPIT.

Research

Assessment of nutrient and carbon cycling and ecosystem processes in restored streams and wetlands and developing improved designs for restored & created environments.

1. investigation of peatland restoration for reducing carbon emissions with The Nature Conservancy to address climate change

2. implementation of stream restoration and other water quality practices with Barr and TNC

3.edge-of-field BMP assessment for Minnesota Pollution Control Agency's state nutrient reduction strategy
