An Action Plan to Conserve the Native Plants of Florida


APPENDIX B: NOTES FOR TABLE 1


1. Pre-settlement figures, unless otherwise noted, are based on estimates by Kautz et al. (1993) from Davis' 1967 General Map of the Natural Vegetation of Florida. Figures are rounded off to three significant digits.

2. Current estimates, unless otherwise noted, are based on Kautz et al. (1993). Figures are rounded off to three significant digits.

3. Unless otherwise noted, estimates for Conservation Areas are taken from Cox et al. (1994), and are rounded off to three significant digits.

4. This figure was obtained by subtracting an independent estimate of 7,000 ha for the current extent of Pine rocklands (see note 12 below) from the figure given by Kautz et al. (1993). These authors apparently included Pine rockland under their Pine flatwoods category.

5. This figure was obtained by subtracting an independent estimate of 6,000 ha for the amount of Pine Rockland now protected in Conservation Areas from Cox et al. (1994). These authors apparently included Pine rocklands under their Pine flatwoods category.

6. This figure was obtained by combining "Sand Pine Scrub" and "Xeric Oak Scrub" estimates in Kautz et al. (1993).

7. This figure was obtained by combining "Sand Pine" and "Oak Scrub" estimates in Cox etal. (1994).

8. This figure was obtained by combining Davis' "Mixed Pine-Hardwood" and "Hardwood Forest" categories as estimated by Kautz et al. (1993).

9. This figure was obtained by combining "Upland Hardwood Forests" and "Mixed Hardwood Pine Forests" estimates in Kautz et al. (1993).

10. This figure was obtained by combining "Upland Hardwood Forest" and "Mixed Hardwood Pine Forest" estimates in Cox et al. (1994).

11. This estimate comes from Snyder (1986).

12. This estimate is based on data from Snyder (1986) and J. O'Brien (pers. comm.).

13. This figure was obtained by combining Davis' "Hardwood Swamp," "Scrub Cypress," and "Cypress Swamp" categories as estimated by Kautz et al. (1993).

14. This figure was obtained by combining "Mixed Hardwood Swamp," "Cypress Swamp," "Shrub Swamp," "Bay Swamp," and "Bottomland Hardwood Forest" estimates in Kautz et al. (1993).

15. This figure was obtained by combining "Mixed Hardwood Swamp," "Cypress Swamp," "Shrub Swamp," "Bay Swamp," and "Bottomland Hardwood Forest" estimates in Cox et al. (1994). The apparent anomaly of an increase in the land area of swamps is an artifact of the different scales used by Davis and by Kautz et al. (1993). Davis' map does not show the thousands of small isolated cypress domes, depression swamps, etc., that were mapped by Kautz et al.

16. Figures for coastal uplands were taken from Johnson and Muller (1993). The Pre-settlement figure includes only coastal uplands on barrier islands, while the current figure includes both barrier island and mainland coastal uplands. The Conservation Areas figure excludes publicly held areas under military jurisdiction.
