AMES, Iowa – The application window is opening July 17 for the fall 2023 Master Gardener training cohort, which will be offered in 55 counties or extension regions. The training will benefit Iowans wanting to deepen their understanding of gardening and horticulture. Area counties offering fall training include: Adams, Dallas, Guthrie, Madison, Mills, Pottawattamie, Ringgold, Taylor and Union.

Iowans wishing to complete Master Gardener training choose a county to complete training through, participate in online learning modules and attend at least four in-person training sessions organized by the county office. After completing the 10-week training, trainees put their knowledge to work with a 40-hour internship in their training county. Applicants have from July 17 to Aug. 18 to apply for the fall session. Training for the fall session begins Sept. 5. Learn more about the program online or through your county extension office.

Alicia Herzog, Master Gardener statewide coordinator with ISU Extension and Outreach, says “Many people have misconceptions about what the Master Gardener program truly is. The Master Gardener training program is about more than just learning how to grow your best garden, although you will learn that as well. Trainees use knowledge gained in training to grow food for those in need, partner with area organizations to design green spaces and present programs in their local communities.” Master Gardeners are volunteers who use research-based information to educate people and coordinate projects that promote healthy communities.

Master Gardeners embody the slogan “Learn it. Grow it. Teach it.” in their various volunteer roles. Presenting public programs is just one way Master Gardeners impact their communities.

Local extension staff can help anyone with questions about joining Master Gardener training this year, including details of when and where in-person meetings will take place in their county or extension region. Iowa State has offered Master Gardener training for over 40 years, engaging more than 15,000 people in learning about gardening best practices.

(Des Moines, Iowa) – Officials with the Iowa Department of Natural Resources (DNR), Thursday, said they were notified on July 10th, of a fish kill on the lower Des Moines River. DNR staff from the Fisheries Bureau investigated and found an estimated 20,000 dead shovelnose sturgeon in a 60 mile river stretch from near Ottumwa to Farmington in southeast Iowa. Freshly dead fish collected on July 11 were submitted to Iowa State University for testing. The investigation began with determining the start and end of the fish kill. DNR fisheries staff collected water temperatures and dissolved oxygen levels at nine locations along the fish kill path and sampled for ammonia. Using the American Fisheries Society (AFS) guidelines, staff started counting dead fish at bridge accesses and then expanded their count to free-flowing areas.

Mark Flammang, Iowa DNR fisheries biologist, said “We didn’t find low levels of dissolved oxygen or high levels of ammonia which is usually indicative of some sort of spill, so it comes down to high water temperatures coupled with the low flows that we are experiencing at present.  Water temperatures are in the upper 80s and exceed levels known to cause shovelnose sturgeon mortality. It was also limited to shovelnose sturgeon; no other species were impacted.”

Shovelnose sturgeon are relatively abundant below Ottumwa, as many of these fish move from the Mississippi River into this section of the Des Moines River during the spring and summer. “Ottumwa has one of the largest populations of shovelnose sturgeon in the world,” Flammang said. The shovelnose sturgeon population is a unique resource in the Des Moines River. According to Flammang, “Many of these fish are over 40 years old. It will take several years to repopulate this long-living fish.”

The affected section of the Des Moines River has had sizable fish kills over the years caused by low water levels and high water temperatures, with the most recent in 2012.  DNR fisheries staff partnered with Missouri Conservation to research the cause of that kill and learn more about the effects to shovelnose sturgeon populations.

If you see dead or stressed fish at a lake or river, call the DNR’s 24-hour spill line at 515-725-8694 as soon as possible. Quick reporting can help DNR staff identify the cause of a fish kill and potentially stop a fish kill in progress.
