Floristic Inventory of Lake Iowa Park

Floristic Inventory for Lake Iowa Park

Lake Iowa park, managed by Iowa County Conservation (ICC), has acres of beautiful restored prairie, but it also has areas that could be true remnants, areas that were never cropped or disturbed. ICC obtained a grant from the Iowa Native Plant Society (INPS) to find out if there are any remnant areas left at Lake Iowa Park and how to best manage them. This information will create a baseline for data collection and help ICC create a management plan to help these remnant areas survive for generations.
Dr. Thomas Rosburg was chosen to complete the floristic inventory with a background including a Ph.D. in Ecology and Evolutionary Biology, masters in plant ecology and bachelor of science in Fish and Wildlife Biology from Iowa State University. With his impressive resume and wealth of knowledge we were very pleased when he agreed to the survey, and with the monetary help of the INPS grant, ICC was able to afford the project.
Iowa County staff created a map that highlighted the areas most likely to have true remnant prairies. These areas were selected using GIS software, aerial imagery, and descriptions of Lake Iowa Park from previous staff members. Using this information, ten areas, 57 acres in total, were selected for study. Dr. Rosburg performed meandering plant surveys on June 5th, July 12th, and September 8th of 2019 to better capture the different growing seasons. He observed 245 different vascular plant species, including many native species.
Dr. Rosburg lays out evidence in his report that Lake Iowa Park may have remnant prairie, which is very exciting and encouraging news. His report includes how to manage these remnant areas. The most pressing issue is the encroachment of invasive species. Dr. Rosberg suggests using multiple stressors against the invasive species at the proper timing. Iowa County Conservation will put areas containing potential remnants at the top of the list when developing the management plan and deciding where to start fighting back against the invasive species that have taken hold in our areas.
We are very excited to see some unusual species and very pleased to know that we have remnant prairies still in Iowa County, Iowa, a place that has been so changed from the original landscape. Thank you very much for the hard work from Dr. Rosburg. Thank you to the Iowa Native Plant Society for making this project possible.

Creepy Camping time is here again!

The staff at Iowa County Conservation is busily preparing escape room clues and lining up talent for the night hike for their annual Creepy Camping weekend that will be held September 27th and 28th.

We have extended the very popular escape room to include 5 more time slots for adults on Friday evening. With these additional time slots added to the 12 time slots on Saturday there will be 17 opportunities to help save planet Earth from an invasion.  An alien has escaped from Area 51 and teams of 2-5 people have 30 minutes to decipher clues left behind or it will contact the mother ship and life on Earth will cease as we know it. If you and have the skills we need your help!

Kids will have the chance to use their brain power to help find a lost artifact in the Park Poacher Escape Room. Teams of 2-5 kids and 1-2 guardians will have 15 minutes to discover and solve clues that lead to the hidden artifact stolen by poachers.

We are also excited to have the Marengo Haunted Barn host a viewing of the Rocky Horror Picture Show on Friday evening. Tickets and prop bags can be purchased at the Nature Center on Friday evening by adults 18 and older. Find a sitter for the kids  and come have a crazy fun time. Costumes are welcome! Tickets will cost $5 per person and prop bags will cost $5. Quantities are limited for props. No outside props are allowed.

We are also holding our annual costume contest, campsite decorating contest, and dummy board tournament again this year as well as trick-or-treating in the campground. We will have a professional face painter at the Nature Center from noon – 4pm on Saturday.

The 4 Leaf Clover 4-H club has been growing some great pumpkins for their pumpkin rolling contest on Saturday morning and the Round House.

With so much planned you should be marking your calendar to come to the lake!

We will kick off Creepy Camping with an outdoor showing of “Hotel Transylvania” at dusk (around 7:30 p.m.) on Friday evening. Genoa Bluffs Farms will be offering Ghost Town kettle corn and drinks for sale.

We are excited to bring back some favorite activities and try out some new activities. This year we are replacing the haunted hayride with 2 Escape Rooms.

There will be a room designed for groups of 2-6 people that are 10 years and older. You will discover that someone in your group has been bitten by a werewolf and you have 30 minutes to find the antidote. There will be a series of problems to solve using clues hidden in the main level and children’s area of the Nature Center. Each group must pay $10 at the Nature Center before entering the Escape Room.

The second room is intended for groups of 2-6 that are 9 years old and under. All groups must be chaperoned by an adult. When you enter the lower level of the Nature Center you discover that a thief has been ransacking campsites at Lake Iowa. You have 15 minutes to find the culprit before your campsite is hit. There will be an easier set of problems to solve using hidden clues in the room and a volunteer will be in the room to provide hints. Each group must pay $5 before entering the Escape Room.

There are 12 timeslots available for the older Escape Room and 21 timeslots for the younger Escape Room. Click on the sign up link below to go to our Sign Up Genius page and select the age group you plan to attend. Please limit your sign up to one time slot and only select one slot for one group of 2-6 people.

Detours for the Summer of 2018

One of the paved roads leading to Lake Iowa Park is being upgraded to cement. The project will run from June to late August/early September.

A short 2 1/2 mile detour may be used by those travelers arriving from I-80 or north of I-80. plan to use 216th Street, the first gravel road heading west after Exit 211 on I-80. This road will curve to the south and turn into G Avenue which will lead to the park.

For a short time we will recommend a longer detour when the intersection of G Avenue and 230th Street is rebuilt. This part of the project should take less than 10 days and will begin August 13, 2018. Drive south of H Avenue and turn west on 266th Street and then north on G Avenue. There will be large brown Lake Iowa Park signs placed to help find the route.
