It was administered by the Kansas Department of Wildlife & Parks. Special thanks to Kansas Department of Wildlife & Parks employees Carl Magnuson and Bob Culbertson. Many individuals worked on or assisted with this project, whether as field workers, preserve management staff, office support personnel or technical advisors. They include Craig Freeman, Bruce Johanning, Hillary Loring, Jim Minnerath, Galen Pittman, Gina Ross and Roger Wells. We are grateful the staff of the Kansas Chapter of the Nature Conservancy for their support and encouragement and to other property owners who gave us permission to visit their land. iii ABSTRACT Management responsibility of the Anderson County Prairie (ACP) Preserve (1370 acres), purchased by The Nature Conservancy (TNC) in 1996 - 2003, was transferred to the Kansas Biological Survey (KBS) in 2006. As part of a plan to initiate conservation management at ACP Preserve, a two-year project was undertaken with three objectives: 1) establish baseline survey and monitoring of Species of Greatest Conservation Need (GCN) and vegetation, 2) control invasive species, and 3) initiate education and outreach with local landowners and natural resource professionals. Three vegetation and habitat-related field protocols were conducted: 1) repeat photography points were established at 63 camera locations across 16 units at the Preserve; 2) vertical and horizontal components of vegetative structure were measured in uplands as a predictor of grassland bird habitat; and 3) floristic quality was measured by quantifying the distribution and abundance of conservative forbs in hay meadow and grazed units. Surveys and monitoring for 19 Species of GCN were conducted on and near the Preserve in 2008 and 2009. Grassland breeding bird abundance was measured using line transects in the core area of the Preserve. Information on summer bird populations in the area surrounding the Preserve was obtained using North American Breeding Bird Survey methodology. Anuran populations were assessed in the spring along a 15-mile driving route. Butterfly populations on and near the Preserve were inventoried with a variety of methods. For GCN Species that were not detectable with the previous methods, species specific inventories were conducted under appropriate field conditions. Overall, 13 GCN Species were documented on the Preserve and 16 GCN Species were observed in the nearby area, most associated with tallgrass prairie habitats. Eight of 12 GCN bird species appear to have healthy populations in the study area, while others, such as Greater Prairie-Chicken and Loggerhead Shrike, have small populations. Non-bird GCN Species with large populations on the Preserve and surrounding area include Crawfish Frog, Massasauga, and Regal Fritillary. Habitat and invasive species management efforts supported by this project were focused on control of the noxious weed, sericea lespedeza. A private contractor and crew surveyed about
