- Wildfire Impacts on Drinking Water and Air QualityLink visible for attendees
The frequency and intensity of wildland fires have worsened impacts to the landscape and to the air column, affecting both drinking water and air quality, which, in turn, affect ecosystem and human health, says Environmental Protection Agency researcher John Iiames. In a 7 p.m. Zoom program cosponsored by TCWP and the Arboretum Society on February 22, Dr. Iiames will share current EPA research on impacts to drinking water quality and the shift of vegetation structure and composition from forest to scrub/shrub due to increasing temperatures and drought conditions.
Over his 23-year career at the EPA, Dr. Iiames has conducted research centering on the examination of the air-water-land interface as it affects both aquatic ecosystems and local and regional air quality. He currently leads a team research effort investigating the effects of wildfire on drinking water quality and the assessment of prescribed fire burn areas in the Flint Hills National Grassland ecosystem in Kansas.
The program will be free, but participants will need register to receive a Zoom link, to be provided at www.utarboretumsociety.org. Contact Michelle Campanis at email@example.com regarding any questions or registration issues.
- Spring Cedar Barren Cleanup/Weed Wrangle®Jefferson Middle School, Oak Ridge, TN
The Oak Ridge Cedar Barren will again be the site of exotic invasive plant removal as we conduct our first official Weed Wrangle® of 2024. Located next to Jefferson Middle School in Oak Ridge, the Barren is a joint project of the City of Oak Ridge, State Division of Natural Areas, and TCWP. The area is one of just a few cedar barrens in East Tennessee, and is subject to invasion by bushy lespedeza, leatherleaf viburnum, privet, autumn olive, mimosa, Nepal grass, multiflora rose, and woody plants that threaten the system’s prairie plants. Our efforts help to eliminate invasives and other shade-producing plants that prevent the prairie grasses from getting needed sunlight.
Volunteers should meet in the Jefferson Middle School Parking lot next to the baseball field at 9 a.m., with sturdy shoes, loppers, gloves, and water. The work session will conclude at noon with a pizza lunch. For more information, contact Jimmy Groton at 865-805-9908 or firstname.lastname@example.org.
