The site is located in the northeast ¼ of Section 34 in Township 32 North, Range 1 East, in Marshall County, Indiana (Figure 1). Preliminary field investigations were conducted on May 12, 13, and 30, 2009; a supplemental field investigation was conducted on July 23, 2009. The purpose of the study was to create a functional status report for the Kline Wetland to guide future care and maintenance planning. In addition, Lake Maxinkuckee Environmental Fund was interested in determining what impacts a potential development to the north of the Kline Wetland may have on the Kline Wetland itself. 2.0 Methodology Prior to the site investigations, an ETR species query for the project area was submitted to the Indiana Department of Natural Resources (IDNR) Division of Nature Preserves Natural Heritage Database. The information received in response to this query is included in Appendix A. Two ETR vascular plant species and two bird species appear on the list generated by the IDNR for the project area. A total of 38 person-hours were spent investigating the site on May 12, 13, and 30, 2009 and July 23, 2009. Additional time was spent in the office identifying unknown plant species. The on-site investigation was conducted by a team of two individuals using meander survey methodology, zig-zagging across all portions of the project area. During the meander surveys, all vascular plant species observed and casual wildlife observations were recorded. Plant communities were mapped across the site; within each community, representative photographs were taken and dominant plant species were noted. A search was conducted for ETR plant species during each field survey. Finally, ORAM was applied to the wetland community to obtain a rating of the functional quality of the wetland system. Botanical nomenclature and acronyms, both in the text and in the species inventories, are taken from Rothrock (2004), which references both the Flora of North America Editorial Committee, eds. (1993+) and the Biota of North America database for nomenclature. The Floristic Quality Assessment (FQA) (Rothrock 2004) computer program (Conservation Research Institute / Conservation Design Forum 1999) (Indiana Database) was used to compile the species inventory. Rothrock (2004) assigns each Page 1 JFNew #0811188.00 Site Assessment Report July 31, 2009 Lake Maxinkuckee Environmental Fund – Kline Wetland, Marshall County, Indiana native plant in Indiana a Coefficient of Conservatism value (C value) from 0 to 10, which is a measure of its ability to withstand degradation. Plants with C values of 10 are typically the first to be lost from a site when the site begins to become degraded. Conversely, plants with C values of 0 can withstand a large amount of degradation. The mean C value was determined by averaging the C values of all species identified on the site. The Floristic Quality Index (FQI) is a function of both the C value and the number of species observed at the site. 3.0 Results 3.1 General Site Description The site is located within the Northern Lakes Natural Region (Homoya et al. 1985). This natural region is characterized by glacial freshwater lakes and thick deposits of glacial material. Soils include loam, clay, sandy loam, and muck. Natural communities in the Northern Lakes Natural Region include bog, fen, marsh, prairie, sedge meadow, swamp, seep spring, lake, dry upland forest, dry-mesic upland forest, mesic upland forest, and floodplain forest. The plant communities at the site fit into the description of the Northern Lakes Natural Region. The majority of the interior of the site consists of emergent marsh, sedge meadow, and shrub swamp communities. The uplands surrounding these wetland communities are degraded but appear to have once been characterized by dry-mesic upland forest and savanna species. The soils at the site are within the Riddles-Metea- Wawasee (higher elevation, drier areas) and Houghton-Adrian-Palms (lower elevation, wetter areas) soil map units (United States Department of Agriculture – Soil Conservation Service et al. 1980). Nine soil units are present on the site (Figure 2). The most common soils on the site are Houghton muck, drained and Wawasee sandy loam, 6-12% slopes. Houghton and Adrian soils are located in depressions, in outwash plains, and in lake plains, and formed in bogs and on glacial lakebeds (USDA/SCS 1980). Wawasee and Metea soils are in areas of rolling topography, located on knolls and ridges formed by glacial deposits (USDA/SCS 1980). 3.2 Plant Inventory and Floristic Quality Assessment A total of 324 vascular plant species were identified at the Kline Wetland site in May and July 2009, with an additional four species identified only to genus (Appendix B). 81% (261 of 324) of the species identified are native to Indiana. The mean C value at the site was 3.0, and the FQI value was 53.9. Rothrock (2004) states that “an intact site accommodating the wide array of species characteristic of a pre-settlement plant community would have a mean C of 5 or greater,” and that “an old field or highly degraded sites (Wilhelm et al. 2003) might be expected to have Mean C values of 2 or less.” Of the 324 species identified at the site, 11% (37 of 324) have C values of 7 or greater, and 4% (12 of 324) have C values of 9 or 10. According to Rothrock (2004), plants with C values of 7 or 8 are “found in high-quality remnant plant communities but Page 2 JFNew #0811188.00 Site Assessment Report July 31, 2009 Lake Maxinkuckee Environmental Fund – Kline Wetland, Marshall County, Indiana appear to endure, from time to time, some disturbance,” and those with C values of 9 or 10 are “restricted to remnant landscapes that appear to have suffered very little post- settlement trauma.” 3.3 Ecological Communities Ten distinct ecological communities were mapped at the site (Figure 3). Each of the communities is described below. Several of these communities, noted with an asterisk (*) below, fit within natural community type descriptions published in Jacquart et al. (2002), although they may not be consistent with the minimum size requirements for classification by the State as a natural area. Community A: Emergent Marsh* The Emergent Marsh community is characterized by the presence of mucky hydric soils, wetland hydrology, and emergent, herbaceous wetland vegetation. It consists of a mosaic of open water and characteristic marsh species. This plant community, which occupies most of the northern half of the site, was likely historically a kettle lake that has undergone natural succession and is in the process of becoming a bog community. Dominant plant species in the Emergent Marsh community include Buttonbush (Cephalanthus occidentalis), Swamp Loosestrife (Decodon verticillatus), Rice Cut Grass (Leersia oryzoides), Small Duckweed (Lemna minor), Purple Loosestrife (Lythrum salicaria), Spatterdock (Nuphar advena), Common Arrowhead (Sagittaria latifolia), Common Bur Reed (Sparganium eurycarpum), and Cattail (Typha spp.). The extent of open water versus vegetation cover in the Emergent Marsh likely varies from year

    Conservation Cover (Monarch Habitat) S. C. Practice Job Sheet 327 Prepared for: Prepared by: Farm: Tract: Date: _____________ Monarch on Ironweed (Vernonia, by Judy Stierand) Monarch caterpillar on Asclepias tuberosa (by Nancy Adamson) Monarch egg Monarch on Asclepias (monarchnet.uga.edu) incarnata (by Judy Stierand) Photo by Judy Stierand DEFINITION Monarchs cannot survive without habitat that includes milkweed (Asclepias species, but also milkvine and swallow-wort) on which to lay eggs. Their caterpillars (larval stage of monarch life cycle) primarily eat plants in the Asclepiadaceae family. With shifting land management practices, essential habitat has been lost from the landscape and monarch populations have drastically declined. Stands of other beneficial native wildflowers and grasses provide nectar, pollen, and structure. Native bunch grasses can assist herbaceous wildflowers in staying upright, while providing cover and sites for pupation/metamorphosis. Native woody plants (trees, shrubs, vines) are also important nectar sources for monarchs, especially during spring when they migrate north. PURPOSE • Provide nectar and pollen for monarch butterflies throughout the growing season • Provide host sites (milkweed, milkvine, or swallow-wort) for monarch larvae • Provide cover (protection from weather and predators) and structure (pupation locations) WHERE USED • Odd or converted areas within farmland margins, field borders, old fields with low plant diversity, logging decks, or areas where exotic plants have been removed (including pasture grasses). • Locations with at least six hours of sunlight. • Areas where exotic invasive plant infestations will be removed or have previously been removed. • Where habitat can be protected from pesticides (they can harm caterpillars and adults). OPERATIONS Pre-planting: Scout the areas at least one year prior to the planned seeding date.

    Terrestrial & Palustrine Plant Communities of Pennsylvania 2nd Ed. Section 2 Palustrine Communities Palustrine Forests Coniferous Palustrine Forests Black Spruce – Tamarack Palustrine Woodland System: Palustrine Subsystem: Woodland PA Ecological Group(s): Basin Wetland Global Rank: G3G5 State Rank: S2 General Description This describes a group of wetland woodlands found mostly in glacially formed, ice-block depressions (kettleholes) of small, higher-elevation watersheds of the glaciated regions of Pennsylvania and in cold- air pockets of drainages at higher elevations of the Unglaciated Allegheny Plateau. These wetlands are dominated by a mixture of black spruce (Picea mariana) and tamarack (Larix laricina). These are trees of short stature (<30 feet) growing as a sparse overstory (<40% cover). The substrate consists of deep, poorly decomposed peat. The woodland is often found interior (i.e., closer to the middle of the wetland) to the Black Spruce-Tamarack Peatland Forest and on the edge of the low-shrub bog. There is generally very little groundwater or surface water enrichment in these systems, resulting in nutrient stressed, stunted trees. Other trees that may occur include gray birch (Betula populifolia) and red maple (Acer rubrum). The sparse woodland gives way to tall black spruce and tamarack (Black Spruce – Tamarack Peatland Forest) away from the bog mat and this peatland forest gives way to a fringe of hemlock and other tall trees at the outer edge of the wetland where organic soils thin and become mineral.
