The name of the Hobart Nature District was officially established by resolution of the Common Council of the City of Hobart, Indiana on July 19, 2017, but the natural areas within the district have been in various states of accessibility and restoration for decades. The resolution by the City Council affirmed the phrase "Hobart Nature District" was the best way to refer to all of the areas contained within the Hobart Marsh Plan which was established by the city in 2013.[2]
The concept behind the Hobart Marsh Plan, which contains the areas now referred to as the Hobart Nature District, has been to capitalize on the extensive areas of native prairie, wetlands and woodlands creating a unique attraction for passive recreation enabling visitors the opportunity to experience local flora and fauna. The Hobart Marsh Plan has sought to connect numerous conservation lands managed by various local partner organizations. It also builds upon the growing regional bike trail network with the potential to become an eco-tourism destination, providing access to many other natural and cultural attractions in the region.[3]
While the phrasing "Hobart Nature District" only became official as of 2017, following the amendment of the Comprehensive Plan for the City of Hobart to include the Hobart Marsh Plan in 2013, conservation efforts and the early steps toward establishment of natural areas within the district date back to as early as 1989 when official support first began to formulate for the preservation of these special places.[4] That initial support led to the establishment of the "Hobart Prairie Grove" that was added to the National Park System as part of a 1992 expansion of Indiana Dunes National Lakeshore (renamed the Indiana Dunes National Park in 2019).[5]
History
1980s
1989
- Hobart Mayor Margaret Kuchta testified in support of adding the Hobart Prairie Grove as a part of the National Park system during hearings on a bill submitted by Congressman Pete Visclosky in 1989. The Hobart City Council also passed a resolution endorsing the proposal.[4]
- David Canright of the Sierra Club Hoosier Chapter presented written testimony dated September 27, 1989 to the Senate Subcommittee on Public Lands, National Parks, and Forests in support of S.2882, a Bill to Enhance The Indiana Dunes National Lakeshore, that cites the importance of including Hobart Prairie Grove in the expansion.[6]
1990s
1990
- Hobart Mayor Margaret Kuchta sent a letter to Senator Dale Bumpers, Chairman of the Subcommittee on Public Lands and signed a proclamation on September 5, 1990 from the Office of the Mayor in support of the Hobart Prairie Grove. The proclamation phrasing noted the Hobart Prairie Grove as a "unique area containing rare and threatened or endangered species" and "preservation of this beautiful natural area will add an important cultural resource to enhance the strength and value of the Hobart community." It further noted, "members of the City Council of Hobart, Indiana are in favor of including the Hobart Prairie Grove in the Indiana Dunes National Lakeshore" and proclaimed the City of Hobart's "support of the Hobart Prairie Grove in the Dunes National Lakeshore expansion bill."[7]
- Senator Dan Coats spoke and submitted a prepared statement in the United States Senate during the second session of the 101st Congress where he noted the significance of the Hobart Prairie Grove as one of the "few remaining unspoiled prairie forests in the midwest" containing rare plants and wildlife.[8]
- A letter of support was written by local ecologist Sandy O'Brien to be included as part of the record of testimony on S 2882, the Indiana Dunes National Lakeshore Access and Enhancement Act. The letter was addressed to the Honorable Dale Bumpers, Chairman of the Subcommittee on Public Lands, National Parks and Forests as part of the Senate Committee on Energy and Natural Resources. The letter provided detailed information relating the geological relationship to the dunes, the ecological quality, and plant diversity found at the Hobart Prairie Grove.[9]
- A letter of support was written by Kim Klimek, president of the Deep River Nature Society, to be included as part of the record of testimony on S 2882, the Indiana Dunes National Lakeshore Access and Enhancement Act. In the letter she noted the Hobart Prairie Grove was of National Park Service quality, having been surveyed by several botanists including Dr. Gerould Wilhelm who had done major botanical surveys of all the Lakeshore units and John Bacone, Director of Indiana's Department of Natural Resources. The Hobart Prairie Grove was noted as being the largest and best tallgrass savanna remnant in Indiana and the last chance to preserve the natural heritage according to experts. It letter also noted adjacent wetlands were evaluated by the Indiana Department of Natural Resources and rated in the 1979 Technical Report No. 303 as #1 priority for acquisition in the Lake Michigan watershed.[10]
1991
- Legislation sponsored by Congressman Pete Visclosky was approved by the U.S. House Committee on Interior and Insular Affairs that would expand the Indiana Dunes National Lakeshore.

It also notes a section of abandoned Elgin Joliet and Eastern Railroad right-of-way is being developed as a hike/bike trail by the Lake County Parks Department that could provide access to the site with minimal impact.[18]
2000s
2004
- The Trust for Public Land, a national nonprofit conservation organization, announced that 219 acres of farmland would be restored to its condition prior to the arrival of the first settlers in Northwest Indiana. This includes 46 acres next to the Hobart Prairie Grove and 173 acres of adjoining farmland and burr oak groves that add to the existing public land in and around the Hobart Marsh region.[19][20]
2005
- The Trust for Public Land announced their multi-year project to protect and save nearly 400 acres in and around Hobart was complete. The area known as Hobart Marsh was a result of a long-term cooperative effort that involved Congressman Pete Visclosky, the Trust for Public Land, the U.S. Army Corps of Engineers, the Indiana Department of national Resources, the Little Calumet River Basin Development Commission, local officials and local conservation leaders.[21]

2009
- Robinson Lake Park, owned by the City of Hobart and located near the center of the Hobart Marsh Area, became the focus of public attention when a private developer sought to acquire the Robinson Lake Park property from the city. A grassroots efforts among community members opposing any sale of the park property formed a non-profit group known as The Friends of Robinson Lake with the mission is to preserve the natural beauty of the park, protect it as a public park, and promote awareness of park activities.[24][25][26] The developer ultimately did not seek further action with regard to acquiring the park from the city citing negative response from city officials and also cited influence by the citizens group the Friends of Robinson Lake for their continued protest to the private ownership of Robinson Lake.[27]
- A September 2009 National Park Service Vegetation Inventory Program of the Indiana Dunes National Lakeshore included descriptions of the Hobart Prairie Grove which is located with the Hobart Marsh area of Hobart, Indiana. The report noted Hobart Prairie Grove provides a small remnant bluff prairie, and mostly a mosaic of oak savanna, woodland, and forest.[28]
2010s
2011
- The City of Hobart identified a need to develop a plan for the area on the west side of the city where numerous organizations including the U.S. Army Corps of Engineers, City of Hobart, Indiana Department of Natural Resources, NIPSCO, and Shirley Heinze Land Trust, own and manage conservation lands. With the need established the city was able to secure a grant from the Indiana Department of Natural Resources Lake Michigan Costal Program to create a comprehensive plan and implementation strategy that would be known as the Hobart Marsh Area Plan. The project cost for development of the plan was $22,920 ($11460 Lake Michigan Costal Grant/$11,460 Local Match).[29][30]
- The City of Hobart Parks and Recreation Department published their Master Plan in 2011 and mentioned Robinson Lake Park and its importance in relation to hundreds of acres owned by the Indiana Department of National Resources within the area that had commonly been referred to as the Hobart Marsh. The Master Plan noted, "Robinson Lake is in the epicenter of 355 acres of DNR property. The property will be commencing wetland remediation in 2011 forward. The Planning Department is in the process of securing a grant that will study and formalize a plan for this sub-area of the city, with Robinson Lake being the focus." The Master Plan further noted among long-range plan relating to the assessment of needs for City of Hobart Parks and Recreation through the year 2020 should include, "Consider purchasing additional property north of Robinson Lake for future development."[31]
- The Long-range Interpretive Plan published by the Indiana Dunes National Lakeshore in March 2011 indicated the Hobart Prairie Grove, located within the Hobart Marsh area, was one of several sites with almost no visitor amenities and little interpretation. The report targeted mid-term 2014-2016 goal tasks to include enhancing interpretive signage at Hobart Prairie Grove to include restoration progress with other interpretive content.[32]
2012
- The Hobart Prairie Grove, located in the Hobart Marsh area, was included in a study by the Indiana Dunes National Lakeshore with details published in the Final White-Tailed Deer Management Plan / Environmental Impact Statement.[33]
- The City of Hobart Parks Department entered into an agreement in 2012 with the Indiana Department of Natural Resources to manage the fish population in Robinson Lake located at Robinson Lake Park which is centrally located within the area known as Hobart Marsh. The state agency does periodic stocking and makes recommendations concerning the lake at no cost to the city.[34]
- Fifth grade students from Ridge View Elementary School in Hobart, Indiana work with Shirley Heinze Land Trust at the Greiner Nature Preserve within the Hobart Marsh Area as part of the Might Acorns Program to collect seeds from native species for future planting.[35]

Some of the trees are more than four feet in diameter and among some of the only remaining old growth trees in Lake County, Indiana.[36]
- The final version Hobart Marsh Plan was presented to the Common Council of the City of Hobart, Indiana for consideration. Among the intentions noted were for it to contain hiking and biking trails, trail heads and gateways.
