About this file
This document is a Bidder Q&A Template from Michigan.gov/MiProcurement for a state contract (Solicitation #250000003397) for Invasive Species Services focusing on Phragmites and Semiaquatic Plants control across multiple state parks. The contract involves treatment of invasive plant species in various Michigan state parks including Algonac, Sterling, Port Crescent, and Bay City Recreation Area, with specific zone-based treatment approaches that vary by location. The project allows for different treatment methodologies including foliar spraying, hand swiping, forestry mowing, and selective herbicide application, with strict guidelines about equipment access, native vegetation preservation, and treatment boundaries.
The contract emphasizes environmentally sensitive treatment strategies, requiring vendors to distinguish between native and non-native plant species, use specific herbicide mixtures (such as imazapyr with glyphosate), and minimize collateral damage to native vegetation. Treatment zones have nuanced requirements, such as treating phragmites stands within and slightly outside designated boundaries, using off-road vehicles like ATVs with park manager permission, and avoiding damage to sensitive ecological areas marked as "no slop zones". The solicitation appears designed to provide flexible treatment options while maintaining ecological integrity, with pricing expected to be itemized for different treatment approaches and careful consideration of native plant preservation.

Section D Description of treatment areas.
Algonac and Sterling
Algonac Sterling
Vendor A was considering bidding on parts of the Phragmites control at Algonac & Sterling SP, but these 2 parks don't appear to have the option of bidding on zones, and must be bid as the entire parks - is that correct?
Yes, At some locations we are bidding things out by zone at others we are bidding out the entire park. This is based on several factors. Priority, budget, ease of managing contractors all factor in to this. While we want to make our projects accessible to all qualified venders, we have to do it in a manner that ensures the desired outcome for the resource. Sterling is in a maintenance phase and it is more economical to have one vender provide treatment.
All Parks Section C
20. Off road vehicles all 21 parks
| 15 and 16 |
| How can we access these zones? |
| ATVs can be used to haul treatment equipment on designated trails and along shorelines, with permission from the park manager. |
All Parks Section D Description of treatment areas.
17 – MAP
DNR PRD Phragmites Contract 2025 Can we drive equipment over other vegetation in the treatment zones?
Equipment can be driven over stands of cattail. Areas of any treatment zones that are native vegetation should not be driven over. No equipment shall be driven in no slop zones (indicated on the map).
Port Crescent Section C 1 –Treatment location Port Cresent 11-Survey/Mapping - Data Update A-G 4 and 5
12 and 13
How should stands that start inside the zone but continue outside the zones be treated?
All phragmites stands that start within the zone and can be seen from the water (up to 1,000 square feet outside zone boundary) should be treated. If there are large stands that start within the zone and continue outside of the zone more than 1,000 square feet, the rest of the stand should be accurately mapped in Field Maps but is not expected to be treated.
Port Crescent
20. Off road vehicles all 21 parks
| 15 and 16 |
| Where can we get equipment into the water? |
| A. Equipment can access the treatments zones from the kayak launch in the day use area and the campground with park manager’s permission. |
Bay City Recreation Area
1 Treatment location
| Regarding woody zones can we cut stump all the bittersweet vines that are large enough in the dormant season and then follow up with foliar the following growing season? |
| Yes |
Bay City Recreation Area
1 Treatment location
| Can we foliar spray zones 2 and 3 and then forestry mow them? |
| Yes, that treatment scenario will be considered. Dogwoods and other natives would have to be left to the extent possible. Pricing for herbicide treatment and forestry mowing should be itemized. |
Bay City Recreation Area Section 3 Treatment Herbicides - B
| 9 |
| Phragmites can be treated with imazapyr? |
| Imazapyr mixed with glyphosate should be used to treat phragmites in this park unless you are within 200 feet of the dripline of an oak or other large tree. For example, the points along Ricoma Beach Road near oak uplands should NOT be treated with imazapyr. (See Section 3b Treatment Herbicides in the spec sheet) |

D. Description of treatment area
| 19 |
| Treatment in this park is targeted at phragmites and purple loosestrife? |
| Correct. It should be noted that there is native loosestrife in this park. Crews should know how to identify the native and non-native plants before starting work. |
| 10 |
| 4. Adjuvants |
| 11 |
| There is no foliar spraying allowed in no slop zones? |
| No slop zones indicate areas of high native plant diversity where collateral damage is not acceptable. In these areas plants should be treated by hand swiping or cone nozzles on handheld/backpack sprayers. Outside of no slop areas collateral damage should be kept to a minimum when most of the vegetation is native. All equipment should drive over stands of reed canary grass or cattail and avoid driving over patches of native vegetation in all zones. |
