Restoration and management of ecologically important sites depend on an understanding of reference conditions and the ability of people to return the site to those historic conditions. Historical ecology research sifts through the data about a site to be able to offer restoration options to land managers. This project demonstrates transitions in na...

... order to maintain consistency in the application of the natural community definitions it was necessary to understand what these natural communities looked like on historical aerials. Figure 8 is a time series of images showing the south middle of the study area, which in 1848 was marsh and bay gall, and in 1944 onward was flatwoods and (a different) marsh. Figure 9 shows the natural community estimate derived from the map and notes. ...

... highly reflective area in the center of the image is a dry flat pine, and south of it a two marshes persisted in a depression, marsh: swamp 1 and manmade lake 2. The changes between 1944 and 1947 were minimal. The natural community map for 1947 reproduced in Figure 18 is largely unchanged from the 1944 map ( Figure 12). This interpretation was confirmed by the small changes shown in Figures 19 and 20 (the complete and binary change maps) and the small numbers reported for the off-diagonal cells in Table 8. ...

... interpretation was confirmed by the small changes shown in Figures 19 and 20 (the complete and binary change maps) and the small numbers reported for the off-diagonal cells in Table 8. The smattering of change pixels in Figures 18 and 19 were compiled by manual photointerpretation. ...

... addition, it seems from Figure 18 that 1947 was a wetter year than 1944. The photos were taken in January and April, respectively, which are both dry months in central Florida As the histogram in Figure 21 shows, the largest magnitude change came from a decrease in marsh, though it was a small percentage of the prior year's area, just over 1.2 ha. ...

... the binary change raster (Figure 26) illustrates, the loss of lake was pretty significant, 24% of its 1947 area. The totality of the changes can be viewed on the complete cross map of Figure 27 The summary of changes is listed in Table 10 and is illustrated in the histogram in Figure 28. The slow expansion of the "bug swamp 1" is illustrated well by the side-by-side aerials in Figure 29. ...
