| Summary: | and grids verified that the vegetation is generally changing annual trend of high river levels in the Spring and low approximately four year intervals, revealed initial are used in GIS spatial analysis, were generated from landuse classified vector files. Cross-tabulated data generated from establishment of willows on the island, followed by from 1962 to 1992 of Choctaw and Lower Cracraft Islands, in from willow to later successional species. River levels growth of willows likely. Examination of aerial photographs in the Spring and germinate when the water began to drop in innundation. Sandbar islands in the Mississippi River levels in the Fall which would allow seeds to be transported levels was inconclusive due to the small number of islands plotted over a forty year period were compared to the possess these characteristics, making establishment and sandy soil to germinate and can withstand long periods of short-lived, early successional species which require moist, studied. succession of later species. Grids and grid overlays, which that the vegetation on the islands was changing. Analysis of the grid overlays were statistically analyzed and indicated the percent of landcover per year, the cross-tabulated data, the Summer. The effect of particularly high and low river vegetation on the aerial photographs. Analysis indicated an Willows (Salix nigra Marsh. and Salix interior Row.) are |
