May 20 Webinar – Amber Fredenburg on creating habitat for our native ground-nesting bees

Amber Fredenburg

Amber Fredenburg

Amber Fredenburg is working on her degree in PhD in Evolution, Ecology and Organismal Biology (EEOB). She is pursuing research to identify the resources that attract ground-nesting bees so we can provide nesting sites for these species in places where their habitats may be limited. She is conducting an experiment where she constructed plots with 5 treatments (bare ground, leaf litter, pebbles, mounded soil, and control) at 21 sites along an urban gradient to test the effect of both urbanization and surface soil substrates. Several of these sites are within areas maintained by FLOW, so we are excited to hear about the results. Her findings should help us increase habitat in our own spaces for these important pollinators.

Nov. 6 webinar – How does road salt impact the river?

FLOW is participating in SALT WATCH – learn what it is and why it’s important


Road salt is everywhere during winter months. It keeps us safe on roads and sidewalks, but it can also pose a threat to fish and wildlife as well as human health.

Fish and bugs that live in freshwater streams can’t survive in extra salty water. And many of us (more than 118 million Americans) depend on local streams for drinking water. Water treatment plants are not equipped to filter out the extra salt, so it can end up in your tap water and even corrode your pipes.

Abby Hileman of the Izaak Walton League of America will discuss how they are studying the effects of road salt on our waterways. The webinar will cover the following topics:

  • How Salt Watch began
  • Goals of the program
  • What is road/winter salt
  • Salt impacts on wildlife, drinking water, and infrastructure
  • How to participate in Salt Watch
  • When to monitor
  • What to do next (advocacy actions)
  • Regional or national results

FLOW began monitoring in 2022 and plans to continue this year. We welcome more volunteers so we can obtain a clearer picture of how road salt is impacting our watershed.




Abby HilemanAbby Hileman is the Salt Watch Coordinator at the Izaak Walton League of America. In her role, Abby leads the efforts of the Salt Watch program, expanding the project into new regions across the country, reaching new groups of volunteers, and providing resources to make lasting change—from data to action. Abby grew up in Western Pennsylvania, where she began her journey as a lifelong conservationist. She has a passion for connecting people to their communities and to nature and believes that small scale actions add up to make a big impact on conservation success.

Sept. 18 Webinar – Debra Knapke on Fall Garden Management

FLOW is pleased to present Debra Knapke, The Garden Sage, as our Sept. 18 webinar speaker. Debra is an avid horticulturalist, teacher, author, and eclectic gardener, who shares her extensive knowledge of sustainable gardening with organizations all across the U.S.

As fall approaches it is very tempting to follow the established practices of garden and yard cleanup, but these common practices are not necessarily beneficial for wildlife and sustainability. Debra will share information on rethinking our fall garden cleanup as garden management, with ways we can work with nature instead of against her. She will share some of her favorite resources for those who want to learn more. Be sure to visit her website at

This webinar will not be recorded. Please register at the link. Time is 6:00 – 7:00 pm, EDT, and there will be time for questions.
