North American tallgrass prairie is dominated by a small                   number of matrix-forming grasses, between which are found a large               number of less abundant interstitial species.  Distributions of                 these species are influenced by disturbance regime and soil                     variability, resulting in a patchy mosaic.  Patches, as defined                 by interstitial species, have been defined in tallgrass prairies                in Kansas and Oklahoma, and vary unpredictably within and between               growing seasons.  The importance of matrix-forming species on the               unpredictable variability of these patches will be tested                       experimentally.                                                                      Schizachyrium scoparium, a matrix-forming species, will be                 removed form half of five 10x10 m2  study blocks, leaving the                   remaining halves as controls.  Patch structure in each block will               be analyzed from cover data form each square meter.  Samples                    will be taken three times over the growing season.  If a matrix-                forming species colonizes the space, patch composition and                      spatial structure will not change.  If interstitial species                     already occupying the patch type colonize the space, patch                      composition and spatial structure will change.  Inter-site                      comparisons will be possible by applying treatments to eastern                  Kansas.  This study will aid in understanding effects of                        unpredictable, Interstitial components on spatial-temporal                      dynamics in tallgrass prairies.
