Mount Baldhead Revegetation

Parks & Public Works Committee Agenda Item Report FROM:

Michelle GibsonAdministrative/Project Coordinator

MEETING DATE:

February 24, 2026

SUBJECT:

Mt. Baldhead Revegetation

DESCRIPTION: City Staff reached out to multiple organizations to solicit proposals in providing revegetation of Mt. Baldhead. Proposals were received from the Kalamazoo Nature Center and the Outdoor Discovery Center. Additional outreach included contact with Davey Research Group; a Zoom meeting was scheduled but did not occur, and no further communication was received. Staff also contacted Black River Habitats but did not receive a response following follow-up emails confirming continued interest. Staff also reached out to MSU Extension, a voicemail was left and no response has been received to date. The invasive species control plan prepared by the Land Conservancy of West Michigan and the City’s Project Charter were provided to interested vendors. Based on these efforts, the enclosed proposals represent the complete set of responses received by the City. The Outdoor Discovery Center proposal includes targeted revegetation of exposed dune areas north of the stairway using native trees, shrubs, grasses, and forbs selected for erosion control, site conditions, and long-term resilience. The scope also includes exclusion fencing and tree tubing, installation of informational and restoration signage to reduce off-trail impacts, and supplemental native seeding to further stabilize soils following invasive species management. After review, staff recommends proceeding with the Outdoor Discovery Center proposal, which best aligns with the project’s restoration goals and long-term objectives for Mt. Baldhead. BUDGET ACTION REQUIRED: N/A COMMITTEE/COMMISSION REVIEW: N/A LEGAL REVIEW: N/A SAMPLE MOTION: Move to approve the Outdoor Discovery Center proposal for revegetation of Mt. Baldhead.

Saugatuck Invasive Species Evaluation and Eradication Project Charter Goal: Identify all invasive species in Saugatuck City public areas including all parks and street rights-of-way.

Develop comprehensive plans to replace invasive species with non-invasive species with an emphasis on native plants and wildlife benefits.

Objectives • •

Inventory invasive species in all public spaces Develop eradication plans and identify areas where replacement plants are required to avoid introduction of new invasive species

Participants

Leader – Nancy Kimble PPW Committee Members - TBD Potential External Resources –ODC, Kalamazoo Nature Center, and Allegan Conservation District Saugatuck Staff – Scott Herbert, Michelle Gibson

Background

Many areas of Saugatuck have significant quantities of invasive species. The ODC inventoried invasives in Saugatuck Wilds Natural Area in July of 2023. The West Michigan Land Conservancy inventoried the Saugatuck Harbor Natural Area in October 2024. The Allegan Conservation District identified invasive species present on Mount Baldhead in the area that requires revegetation. Altogether, the list of previously identified invasives is long. In addition to invasive plants, the Hemlock Wooly Adelgid has previously been identified and treated in some areas. Milfoil has been treated in Kalamazoo Lake/River. The following areas have been identified for study: • • • •

Mount Baldhead Park Mildred E. Peterson Nature Preserve Remaining Parks (these are manicured so few invasives are anticipated) Saugatuck Roadsides

Approach • •

Contact potential vendors that could help with the identification of invasive species and potentially work with us to eliminate these in the future Identify vendors that can provide removal services and request RFP submission. The following vendors have been identified o Allegan Conservation District o Kalamazoo Nature Center o Outdoor Discovery Center Provide vendors with this project charter and city maps that specify the areas to be evaluated

Project Exclusions Deep water aquatic areas are excluded from this project as they are already covered by another project

Saugatuck Invasive Species Evaluation and Eradication Project Charter Project Risks and Mitigation:

Risks: Costs for species removal and replacement plants could be significant. Budgeted funds may not be available in 2026. External resources may not be available in our timeframe.

October 7, 2013

INTRODUCTION At the request of The Land Conservancy of West Michigan, Cardno JFNew and West Michigan Tree Services have been contracted to write a remediation plan for Mount Baldhead Park in Saugatuck, Michigan. The purpose of the remediation plan is to design a successful strategy to recreate the native habitat that was lost due to tree losses that occurred as a result of Oriental bittersweet control treatments.. To control a growing infestation of Oriental bittersweet on Mount Baldhead, the City of Saugatuck gave permission to the Land Conservancy of West Michigan to administer applications of herbicides for Oriental bittersweet control. These herbicide applications occurred in 2010 and 2011. Oriental bittersweet (Celastrus orbiculatus) is an exotic, invasive vine that can destroy native habitats. The vine overruns trees, woody-plants, and ground covers. Oriental Bittersweet can become so pervasive the vines block sunlight to the foliage of desirable trees and native plants. This remediation plan is intended to address the removal and replacement of impacted trees, as well as any soil erosion that may have occurred as a result of said impacts. 2.0

MT. BALDHEAD IMPACTS

Tree Impacts Tree impacts were limited to the northeast side of Mount Baldhead and the perimeter of the parking area at the base of the hill. The area inspected extends from the top of the hill to the base of the hill, and from the path on the northeast side of the hill southward to approximately thirty feet south of the stairway. The majority of the herbicide damage was limited to deciduous trees (there are very few conifer trees on Mount Baldhead). The size of the trees did not appear to have any influence on the extent of herbicide injury. Tree species, however, did have an influence. Sugar maples, red oaks and American basswoods were acutely affected. The mulberry trees and locusts incurred less damage. There is a grove of trees, approximately fifty feet in diameter, located three quarters of the way up the slope that suffered no damage. Of the 191 trees inspected, 148 trees are dead or suffered more than fifty percent crown loss and have little to no chance of survival (Table 1). Forty three trees were not affected or suffered less than fifty percent crown loss.

Maple, oak and basswood comprised two-thirds of the trees examined. The remaining species consisted of ash, wild cherry, American elm, American beech, sassafras, locust, mulberry, walnut, tulip poplar, and Ailanthus. Three of the trees examined died due to being overrun by the Oriental Bittersweet vines and a few trees (not listed in the inventory) were dead prior to 2010. Most of the damage we encountered was caused by the herbicide applications. Unless otherwise noted on the tree inventory, trees listed as being dead have perished due to the bittersweet treatments.

Site Erosion The loss of tree canopy has had several effects on the understory of the ecosystem. These effects include an increased amount of sunlight that has allowed the establishment of an herbaceous understory not likely present prior to the tree impacts. Dominant species in the understory include garlic mustard (Alliaria petiolata), bedstraw (Galium aparine), soapwort (Saponaria officinalis), and Oriental bittersweet (Celastrus orbiculatus). These opportunistic species establish in recently disturbed areas, such as those present at the impacted portion of Mt. Baldhead. One positive side effect is the new vegetative cover is helping to stabilize the soil.. Cardno JFNew Project #121007

When comparing the trees south of the staircase to the trees north of the staircase, there is a noticeable absence of vegetative diversity on the north side. The more native ecosystem south of the stairs has layers of herbaceous shrubs and tree cover, while the north side vegetation is limited to primarily the afore mentioned herbaceous cover. The north side will become more stable if these vegetative layers can be re-established. The soil on the north side has few signs of active erosion. The vegetation and detritus that are present are minimizing erosion. However, small amounts of soil movement/erosion s are evident. The erosion is primarily superficial and limited to comparatively small (10-20 square foot) areas. No new erosional rills or gullies were observed. What erosional activity has occurred is primarily where there is a lack of detritus or herbaceous vegetation, or where public use has created disturbances. There is a walking path on the north side of Mt. Baldhead. Although not related to invasive species treatments, this path creates potential instability because vegetation is unable to become established. With the loss of tree canopy cover, this path has a greater potential to erode if public use continues to inhibit the ability for vegetation to become established. As a critical dune, Mt. Baldhead has been historically subject to movement. This is particularly evident where a wood retaining wall was installed at the toe of the slope to impede soil movement. Soil movement/erosion has historically been minimized by the presence of vegetation and detritus throughout the dune, as is evident in predisturbance photos and an evaluation of the non-impacted south side of Mt. Baldhead. Long-term stability of the impacted north side of the dune will depend on the presence of vegetation and detritus in some form. Recommendations for increasing stability are provided below. 3.0

TREE REMOVAL AND REPLACEMENT

Tree removal and tree replacement are required to address the 148 trees that suffered mortality. In order to maximize the unique social, cultural, and environmental benefits provided by Mt. Baldhead, tree removal and tree replacement measures must account for public safety, soil stability, and the ecology of the dune ecosystem. Tree Removal There are currently 148 trees (Figure 2) on Mt. Baldhead that have been identified as dead or dying as a result of invasive species treatments. For public safety and soil stability reasons, each of these 148 trees must be addressed in a manner that will protect the public safety and enhance resident ecological community. Of the 148 dead or dying trees, 42 trees (Figure 3) have been identified as hazard trees. A hazard tree is defined as any dead and/or damaged tree caused by the application(s) Cardno JFNew Project #121007

Page 3

of non-selective herbicides, where limbs and/or the whole tree has the potential to fall and reach park visitors using the stairway, foot paths, private homes, and/or the parking lot or pavilion area. For public safety reasons, all hazard trees should be removed and the wood and brush scattered throughout the site, as described below. In addition to the 42 hazard trees, an additional 45 trees should be removed to reduce potential soil erosion that could be caused by wind throw and to encourage the reestablishment of the native ecological community. Scattering tree trunks and crowns throughout the site will re-introduce detritus to the system, provide microbial habitat and also serve to stabilize the soil. The remaining dead trees should be left standing in place for wildlife habitat. Tree Removal Methodology Removal of dead or dying trees shall be treated in one of two ways. They will either be left standing in place or they will be cut and scattered in appropriate locations for the reasons described above. Trees will be cut by the safest and most practical means necessary. Stumps will be cut flush to grade. Wood and brush will be spread throughout bare or open areas so as not to form “heaps” or piles. Tree crowns will be cut small enough to lay on the hill so that no portion extends more than four feet vertically from the ground surface. All cut material will be placed on the hillside in a manner that mimics natural detritus and minimizes erosion—cut material will not be placed in a manner that exacerbates erosion in any way. Tree Replacement To replace the 148 impacted trees, a combination of potted and bare-root trees should be installed. The 148 impacted trees should be replaced at a 1:1 ratio with potted stock, while additional bare-root stock will be installed at a 2:1 ratio. This would bring the total proposed tree replacement to a 3:1 ratio. The unique ecology of Mt. Baldhead suggests that an emphasis be placed on selecting native tree species from local tree sources. This will best insure a re-establishment of the pre-application native conditions. However, not all of the impacted species are commercially available from local (Michigan-grown) genotypes. The recommended tree replacements have been narrowed based on commercially available local genotype species available from Michigan sources. Oriental bittersweet continues to inhabit portions of Mt. Baldhead. As this plant will inhibit the establishment of native trees, it will need to be addressed.

PROPOSAL FOR CONSERVATION SERVICES This proposal was created for: City of Saugatuck – Mount Baldhead Park Mt Baldhead Park Trail, Saugatuck, MI 49453 General Background and Scope of Work: The purpose of this proposal is to restore ecological health at Mount Baldhead through targeted invasive species management and the replanting of native dune vegetation. Previous control efforts done by a separate contractor inadvertently caused mortality to significant canopy cover and reduced dune stabilization, creating openings now dominated by invasive plants. Following a recent survey of the site, our team recommends the following management and replanting plan for 2026: 1. Invasive Species Management (see Appendix A for map) ▪ Several highly invasive species are present that threaten the integrity of the dune habitat, including: garlic mustard, multiflora rose, Asian bittersweet, Japanese barberry, tree-of-heaven, phragmites, and black locust. ▪ Our management approach will prioritize safe and targeted control methods that avoid unnecessary herbicide use and prevent damage to surrounding vegetation. Hand pulling will be implemented where practical, while cut-stump and hack and squirt treatments will be used to ensure precise and minimal herbicide applications. When foliar applications are necessary, they will be applied selectively and with safeguards to prevent off-target impacts. ▪ Includes procurement of all necessary permitting to apply herbicides through EGLE and MDARD. ▪ Note: Many of the invasive species listed above typically require sustained and repeated management to successfully control. Effective treatment generally requires repeated management efforts over a period of multiple years to achieve meaningful reduction or eradication. Our team will continue to monitor the population annually and will provide updated pricing and management recommendations each year. The allows for adaptive management strategies based on observed changes in site conditions and treatment efficacy year-to-year. 2. Dune Revegetation ▪ Large areas of exposed soil across the dune north of the stairway currently face high risks of erosion and rapid recolonization by adjacent invasive species. To stabilize these areas, prevent further invasive spread, and enhance both habitat quality and aesthetics, we propose installing a diverse mix of native trees, shrubs, grasses, and forbs in the vacant space. ▪ Species selection will highlight erosion control, drought tolerance, and deer resistance, recognizing the heavy browsing pressure present at this site. Plantings will be matched to each micro-site’s soil and sunlight conditions to maximize survival rates and ecological value. ▪ Trees: Sugar Maple (Acer saccharum), Tulip Poplar (Liliodendron tulipifera), Basswood (Tilia americana), White Pine (Pinus strobus), Oak (Quercus spp.), Bladdernut (Staphylea trifolia), Serviceberry (Amelanchier spp.), etc. ▪ Shrubs: Witch Hazel (Hamamelis virginiana), Sand Cherry (Prunus pumila), Ninebark (Physocarpus opulifolius), Spicebush (Lindera benzoin), Arrowwood Viburnum (Viburnum dentatum), Northern Bush Honeysuckle (Diervilla Ionicera), Sweet Fern (Comptonia peregrina), etc. ▪ Forbs/graminoids: Canada Wild Rye (Elymus canadensis), Bottlebrush Grass (Elymus hystrix), Little Bluestem (Schizachyrium scoparium), Beach Grass (Ammophila breviligulata), Sand Reed (Calamovilfa longifolia), Penn Sedge (Carex pensylvanica), Columbine (Aquilegia canadensis), Hairy Puccoon (Lithospermum caroliniense), Dotted Mint (Monarda punctata), Flowering Spurge (Euphorbia corollata), etc.

INITIAL______

Approximately 500 native plants will be installed throughout the unit, including, bare-root, 1-3 gallon, and 4” plugs. • Protective exclusion measures such as tree tubes and four 900 ft2 sections of 6'tall exclusion fencing will be implemented where applicable to prevent herbivory and physical damage to developing plantings (See Appendix B for layout). • Informational signage will be installed in high-traffic and erosion-prone areas to encourage public awareness, limit off-trail usage, and protect restoration efforts (See Appendix B for examples). • “Sensitive Habitat Area – Keep Out” signs (4"x6") will be placed at key intervals and potential access points throughout the unit as needed. • A total of four (4) “Restoration in Progress” signs (2'x3') will be placed in key locations to minimize off-trail use and reduce disturbance from hikers. • In addition to the live plantings, a custom native seed mix highlighting duneadapted forbs and graminoids will be seeded following invasive species management efforts to enhance diversity and further stabilize exposed soils.

Project Timeline: • Invasive species management ongoing during the 2026 growing season • Live plantings and native seeding will be phased as invasive species treatments allow, from spring through early fall of 2026 • Signage and exclusion fencing will be installed immediately following planting. Project Budget: • Invasive Species Management in 2026 - $10,000 (billed in June 2026) ☐ • Dune Revegetation (500 plants) - $11,860 (billed in June 2026) ☐ *PLEASE CHECK THE APPROPRIATE BOXES ABOVE TO INDICATE ACCEPTED SERVICES Note: This proposal accounts for pricing of all labor, materials, and equipment necessary in order to perform the outlined invasive species management plan. If additional work is required beyond the scope of this proposal, we will provide written notification and pricing will be determined on a time and materials basis. Exclusions: This proposal does not account for: • Installation of exclusion fencing beyond what is outlined in this proposal. • Production and installation of signage beyond what is outlined in this proposal. • Installation or management of irrigation features. • Removal of standing dead plant material following invasive species control measures. • Replacement of damaged lawn, landscape plants, trees or shrubs as a result of nearby invasive species control measures. • Replanting of native vegetation following invasive species control measures (unless otherwise stated on the proposal). ** We are happy to assist with any of the above items upon request through a separate proposal.
