Big Muddy Speaker Series

“Avifauna Richness in Isolated Parks: Benefits of Parks along the Mississippi Flyway”

Presentation by J Devonshire

When: February 8, 2017, Social hour at 6 p.m, Presentation at 7 p.m.

Where: Big A's on the Riverfront308 N. Main St., St. Charles, Mo 63301

Urbanization causes fragmentation creating “islands” of natural habitat. The resulting fragmented landscapes represent a challenge for migratory and resident species because of decreased connectivity among fragments. We examined the effects of urbanization on avifauna communities in remnant and restored parks in the greater St. Louis area (St. Louis), Missouri and Illinois, USA.
St. Louis is located along the Mississippi flyway, a significant North American migratory bird route, and ranks second among the most sprawl-threatened large cities.  The best predictors of resident bird (i.e., breeding and wintering) species richness was park area and external developed area within 5 km, a surrogate for isolation. We suspect that the high species richness in parks in heavily urbanized areas is explained by the parks’ relatively large size and the funneling of species to two large parks within the most urbanized areas of St. Louis. For migratory species, the best predictors were habitat diversity and developed area within the park.
As development continues to transform natural habitat along important avian migratory flyways, urban planning that includes large, diverse natural areas within urbanized landscapes is key to conserving local and migratory avifauna diversity.

Presentation is FREE and open to the public!

River Soundings

 A Discussion on Living with Rivers

Wednesday February 22, 2017, 5:30 pm coffee, snacks, networking, 6 pm program begins

Forest Park’s Dennis & Judith Jones Visitor and Education Center5595 Grand Drive in Forest Park – event will be in the Learning Lab


Contact: Greg Poleski – or 314-402-5233 or CLICK HERE TO REGISTER.

River Soundings is part of a series of talks and discussions on river conservation and floodplain and watershed management sponsored by Greenway Network, a Stream Team Association based in St. Charles County. The program features three short talks relating to Living with Rivers, by panelists from our community. The panelists will then discuss audience questions, led by the panel moderator, Jean Ponzi

Panelists for River Soundings include:

Tony Messenger -  will address the changing narrative on flooding in St. Louis. Tony Messenger is a writer with the St. Louis Post-Dispatch who was honored with Greenway Network's 2012 Conservationist Award for a series of newspaper articles on our rivers. His columns report and comment on many aspects of life in our community. He has earned Pulitzer Prize finalist recognition, the Sigma Delta Chi Award for Editorial Writing from the Society of Professional Journalists, the Burl Osborne Award for Editorial Leadership from the American Society of News Editors, and the Walker Stone editorial writing award from the Scripps-Howard Foundation.

Robert Criss - will discuss how the record winter flood that impacted our region one year ago was aggravated by human activities. Robert Criss, Ph.D, is a professor of Earth Sciences at Washington University. His research spans many disciplines and has appeared in more than 40 different scientific journals, several government series, and several books. He has conducted extensive field and geochemical work in many different geologic environments in North America. In his long academic career he has taught courses in Geochemistry, Hydrology, Stable Isotope Geochemistry, Chemical Thermodynamics, and Geochronology.

Brad Walker - Will discuss what was the Lower Missouri River supposed to look like under the Pick-Sloan Plan Act.  A major component of the Pick-Sloan Plan was not followed, and it is probable that this lack of adherence has been responsible for numerous problems on the Lower Missouri River. Brad Walker is River Director for the Missouri Coalition for the Environment. He is a regional leader in work for sound watershed management. His work includes research and writing on watershed issues and public education/outreach, helping to inform citizens about damages to our watersheds and how to mitigate those damages. Prior to his work in the conservation and environmental sector, Brad worked for over 20 years in the construction industry, primarily performing construction management for large wastewater treatment plants in the western US.

Jean Ponzi, our moderator, produces and hosts the weekly environmental interview show “Earthworms,” a feature of KDHX Community Radio since 1988, now podcasting. She works at the EarthWays Center of the Missouri Botanical Garden, managing sustainability programming for businesses, operating the Garden’s Green Resources Answer Service, and serving on the BiodiverseCity St. Louis program team. She is in demand as a speaker, for general public and business audiences, on topics including recycling and waste reduction, indoor air quality, native plant landscaping, energy efficiency – and the ecological and economic connections between these kinds of practices. Jean was recently honored by the Missouri Coalition for the Environment with the Kay and Leo Drey Award for Environmental Stewardship and by the Population Media Center with a Global Media Award for Best Radio Show.

Team Leader Training at Columbia Bottoms

Sunday, March 5, 2017 10:00am

Open to everyone in the region interested in being a team leader.

Coordinating hundreds of volunteers takes a little bit of effort.  Team leaders are volunteers who step up to lead small groups on clean ups, plantings and invasive removal projects.  It is a great way to get more involved and to take your love of  making a difference in our environment to the next level.  Team leader training is open to everyone in the Confluence Region who is interested learning more about what is involved. 

The Spring training is for stream clean ups.  We will talk about safe handling of trash, what to watch for, some safety issues and then we will go out and do some cleaning up.  You will have an opportunity to talk one on one with experienced team leaders, to hear their stories and ask questions.  Lunch is provided and team leaders will be given special t-shirts or other gear to identify them in the field.  

While we would love to have you join us as a leader for the Confluence Trash Bash, there is no need. This is open to any clean up in the area.  

Additionally, if you would like to practice on a small scale, we have the monthly Conservation Crew events.  Sign up.  Come out and guide the group with an experienced leader at your back.

 Join a Greenway Network Conservation Team

Volunteers are needed for picking up trash, planting, removing invasive plants and doing other needed work on public lands and to help at events such as Earth Day, National Public Lands Day, Mission:Clean Stream, Confluence Trash Bash and Race for the Rivers. Service days will be held at many sites, including Riverlands,in West Alton, Riverwoods in Bridgeton and many local parks near you.

Team members are asked to pledge to support three service events this summer. Members will receive gloves, a water bottle, and a t-shirt at their first volunteer event.

Team leaders are needed to help coordinate service projects. Team leaders will receive special training to support events. Pledge to support five volunteer events and you are eligible to be a team leader and receive special recognition.

Single day volunteers are welcome and make up the majority of our volunteers! The work is rewarding, enjoyable, sometimes wet and muddy, but always worthwhile. Look for volunteer opportunities on our website or to join Greenway Network Conservation Team's monthly work party at the Riverlands area in West Alton, Mo.
