ISU Extension Sesquicentennial Service Project
Decatur County, May 12, 2007


Decatur County ISU Extension held its ISU Sesquicentennial Service Project on a beautiful day, Saturday, May 12, at Slip Bluff Park near Davis City. Slip Bluff is a county conservation board park that has a very high bluff with a splendid scenic overview of the Grand River valley in the Davis City area. The park lies adjacent to and just east of Interstate 35 and can be viewed from the I-35 rest stop just north of the Lamoni exit. The park has a small lake, camping facilities, picnic shelters, hiking paths, and many wonderful natural features, including a breath-taking scenic overlook view high above the Grand River.

The park is undergoing a transformation, or more accurately, a renovation of sorts. The Decatur County Conservation Board, U.S. Fish and Wildlife Service, and Southern Iowa Oak Savanna Alliance (SIOSA) have teamed up and embarked on a project to restore the park to an Oak Savanna terrain, which was the predominant prairie/woodland landscape in this area prior to settlement. The project has begun with the first phase consisting of removal of undesirable brush and understory which has invaded the wooded areas plus tree thinning and timber stand management. Other phases will include prescribed burning in the wooded and grassland areas to keep unwanted brush down and encourage growth of native grass and forbs as well as groupings of desirable oaks and other hardwood species. Gregg Pattison, with the U.S. Fish and Wildlife Service, is a prescribed burn specialist and is working with this and other savanna restoration projects in the area. He is an ISU alum and the husband of Karen Pattison, our ISU Extension Youth Field Specialist.

This ISU Sesquicentennial project was planned and developed by Gregg Pattison, Rich Erke, Decatur County Conservation Board Director and Jack Van Laar, CEED, all ISU alumni. It was designed to compliment the restoration work at Slip Bluff Park and consisted of erecting several sections of rail fence as wings on each side of the short stone wall at the scenic overlook. The face of the bluff at the scenic overlook is very steep and over time is gradually sloughing or sliding in thin layers toward the river bank below. This is a natural process from which the park derives its name. Thinning of unwanted brush has already been done on the face of the bluff opening it up tremendously. However, as wanted vegetation becomes established, it will be critical to keep foot traffic off the bluff to prevent accelerated damage and erosion to the bluff.

This rail fence is an attractive complement to the scenic overlook as well as deterrent to traffic into this fragile area. Our crew consisted of 11 hard working individuals. Participants enjoyed a picnic lunch consisting of hot dogs roasted over an open fire, chips, baked beans, drink and chocolate chip toll house cookies for dessert.

Jesse Randall, Assistant Professor in Natural Resources and Ecology Management, was the ISU Campus representative and presented the plaque commemorating the project to Jack Van Laar and Rich Erke. The plaque will be affixed to a permanent concrete marker post to be erected at the edge of the stone wall next to the east rail fence wing.

Our sincere thanks go out to everyone who participated in this unique project which will benefit all visitors to the park and help preserve an important part of our county’s natural heritage.
