The State of Pollinators in Iowa

The State of Pollinators in Iowa

Special Note: This blog post is based on a presentation made by former PRI Watersheds and Wildlife Coordinator David Stein. Editing and Design by PRI PR & Marketing Coordinator Mike Kellner.

Pollinators in Iowa are disappearing at an alarming rate due to climate change, disappearing habitat, pesticide use, and disease.

Prior to European settlement, about 85% of Iowa was covered with prairies, grasslands, wetlands, and forests. Now, less than one-tenth of a percent of Iowa’s original prairies are left while the rest of its land has been plowed for cultivation, cleared for development, or otherwise altered creating a lack of habitat, food, and water for pollinators in our state. In a sense, Iowa’s once-lush landscape has become a virtual desert, where more often than not, there is no food or water for pollinators sometimes as far as the eye can see.

Reflecting on the National Fish and Wildlife Foundation Project

Reflecting on the National Fish and Wildlife Foundation Project

This project that was funded through the National Fish and Wildlife Foundation (NFWF) is coming to a close early this December. It allowed us the means to engage with several local people about the need for wildlife and pollinator habitats in central Iowa. I’d like to take the time to reflect on all the great work that we’ve done through this grant. Here are the highlights of our accomplishments of over the last three years with a few numbers.

6 Field Days were held on the following topics: Hamilton County Wetlands, CRP/Pollinator Habitat, Saturated Buffers, Multi-Scale Habitat Restoration, Story County Wetlands, Orchard, and Prairie Pollination.

220 People attended field days between 2019 and 2021

CRP Pollinator Habitat Field Day

5 Webinars were held in 2021 on the following topics: Water Quality, Ethnobotany, Planting for Pollinators, Citizen Science Opportunities, and Habitat Financial Assistance.

119 People attended our webinars in 2021

Which Water Worry Where Webinar

6 Water Quality Snapshots were held each spring and autumn between 2019 and 2021.

113 Volunteers tested water quality during our snapshot events.

36 Landowners were provided with technical assistance for nutrient reduction, water quality, wildlife habitat, and erosion issues.

30 Species of native plants were offered through the Community Seed Bank Program started in 2019.

96 Landowners were provided with native seeds through the Community Native Seed Bank

179 Acres of pollinator habitat were restored or enhanced through the Community Native Seed Bank

Thank you all for joining us again on the newest addition of the Watersheds and Wildlife Newsletter. Let me go ahead and start by thanking everyone for making our most recent events a massive success! We had a lot of events in a row, and it made us so happy to see the massive amount of support shown to us. On August 28th we held our final field day for the year, and for the National Fish and Wildlife project. This field day was called Bumble Bees and Berries and was held at both the Berry Patch Farm and Jennett Heritage Area. We were lucky enough to partner with Story County Conservation, the Story SWCD, and Monarch Joint Venture. We had a total of 40 people stop by to learn all about pollinators, orchards, and prairies.

Chad Pregracke Presentation

On September 30th, in collaboration with the City of Ames, we hosted a river cleanup lecture by Chad Pregracke at the Ames City Auditorium. His talk then inspired us, and 26 other environmental enthusiasts to get our hands dirty and our feet wet, and do a massive cleanup in Ioway Creek on the 2nd.

Our largest event by far, however, was the 2nd annual Wild and Scenic Film Festival, again held at Ames City Auditorium on October 1st. This was a night full of inspiring films, partnership building, and showing support for conservation. We hope you all enjoyed the event, and look forward to next year’s show!

On October 23, we hosted this year’s second Water Quality Snapshot, where volunteers helped collect vital data that we can use to evaluate our waterways. Starting in November our annual Native Seed Bank will be re-opening. We hope that this year’s seed bank will be able to help restore more acres than 2019 and 2020 combined! On November 2nd, we alongside Story County Conservation will be hosting a webinar to update the public on the progress being made towards Story County water quality monitoring.

Like always, for more details about all of our upcoming events, please follow us on social media, and visit the events page on our website. Thank you again for joining us and enjoy this edition of the Watersheds and Wildlife Newsletter.

Thank you all for joining us for the most recent edition of the Prairie Rivers of Iowa Newsletter.  The Watersheds and Wildlife Program has been hard at work over the last few months making progress on several projects.  Some of the major work that we’ve done has been installing pollinator gardens in both Ames and Boone.

These gardens included 38 total plants from 14 species.  All plants that were included are native to Central Iowa and provide both food and shelter resources to pollinators.

The Ames garden is located in Northridge Park, and the Boone garden is located in Cap Erbe Park.  I would like to thank Keith Abraham from the Ames Parks and Recreation Department, and April Burch from the Boone Parks Commission for all of their help.  Moving forward, we will be designing and installing informational panels that explain the benefits of these gardens.

This time of year also marks the beginning of a new initiative from the Watersheds and Wildlife Program, which is pollinator species monitoring.  Over June, July, August, and September, we will be visiting public lands in Story County, and conducting surveys on pollinators and nectar plants.  This will give us the opportunity to be able to track what species are on the landscape in real-time, while also being able to announce any findings of rare, threatened, or endangered species as we see them.  If you see me out in a Story County park with a net and binoculars, feel free to stop and say hi!

Missing Monarchs, What it Means, Why it Matters, and How to Help.

Missing Monarchs, What it Means, Why it Matters, and How to Help.

It seems to be a yearly event nowadays, that we wait with bated breath for the release of the year’s final monarch count from Mexico, where they spend the winter.  Similarly, each year, we’re let down with the news that the population has fallen again.  This same thing has happened this year, with MonarchWatch’s yearly report from the field.  Yet again we’ve seen a decline, with the total area covered by monarchs in their overwintering site falling 26% compared to last year, now only covering 2.1 hectares (5.2 acres).  For a comparison, the indicator of a healthy Monarch population is an overwintering area of 6 hectares (14.8 acres).  So what’s going on here, and more importantly, what does it mean?

It’s time for my controversial but true statement, monarchs really aren’t good pollinators. There, I said it! They don’t contribute very much to fruit or seed production, and they certainly don’t help with our food security.  So what’s the deal?  Why are we spending our time and energy monitoring and reporting on them?  Well, there are a lot of reasons why protecting them matters. For example, if you felt uncomfortable, angry, or saddened by any of my previous statements in these last 2 paragraphs, then that’s a fantastic reason on its own to protect them.  

Monarchs have a special place in the culture of Iowa, the Midwest, and North America as a whole.  Most people that I talk to about the plight of the monarchs reminisce about seeing them delicately flying around in the summer.  Many more, myself included, have fond memories of raising and releasing Monarchs as part of countless elementary school science classes.  For many people, monarchs were a great introduction to the wonders of nature, highlighting how creatures can grow and change through time in order to adapt to their surroundings.  Monarchs also teach us about migration and animal movement, how creatures overcome great odds, and large distances all for the sake of the next generation, who in turn will repeat the cycle.

Outside of nostalgia, metaphor, and symbolism, monarchs have an important role in conservation as what’s called an indicator species.  Because of their size, recognizability, and large range, tracking a trend in the population of monarchs is far easier than, say, a small, camouflaged, yet more-efficient pollinator.  If we know that both of these creatures have similar habitat and dietary needs, it is in our best interest, time and energy-wise to focus on the big, orange, easy-to-track species.  By providing the good habitat, food, and space for a monarch, we can expect other pollinators to use those resources in a similar way.  Similarly, if we see declines in monarch numbers, we can use that data to assume that other species of pollinators are also declining for similar reasons.

It’s in our best interest to protect monarchs, because by extension, we’ll be protecting pollinators as a whole.  Now you may be wondering how you can help monarchs and pollinators, what things you can do to help reverse these declines?  The good news is that no matter where you live, or how much land you have, you can help your local pollinators.  All it takes to start is a few seeds, easy enough right?  

Well, no…you need to make sure you plant the right seeds for the job.  Monarchs and pollinators evolved right alongside our native plants, so those are the plants to grow that will cover all of their nutritional needs.  If you aren’t able to access native plants, or don’t have the space for them, non-native nectar plants like lavender, mint, and clover are all good options (just make sure that they don’t spread outside of a designated area!)  Also plant “host plants.”  These are specific species of plants that caterpillars will eat to prepare them for becoming butterflies.  The host plants for monarchs are famously milkweeds, but every other butterfly has their own version of this.  Finally, your plants should bloom throughout the season, with species blooming continuously between May and October.  This way, you’ll know that you’re providing a source of flood for hungry pollinators at all times.  

Pollinator Gardens Provide Nectar Throughout the Summer.

Monarchs may not be the best at pollinating, but they are an important symbol.  They symbolize migration, change, and the cycle of nature.  They also symbolize pollinators as a whole, illustrating their needs, their declines, and their need for protection.  Again, by protecting monarchs, providing them with spaces for them to grow, thrive, and eventually venture out from, we’ll be able to protect all of our pollinators.
