Abstract: Seven approximately 3.3-ha plots were established near Moore Haven, FL, along the southwest Lake Okeechobee levee road. After mechanical uprooting, stacking, and burning all melaleuca trees, the areas were harrowed with a disk. Two plots were treated with Rodeo herbicide, two with Velpar L, one was planted with common baldcypress (Taxodium distichum (L.) Richard) and red maple (Acer rubrum L.), one was a conttol with no further treatment and one had regrowth melaleuca manually removed. One and two years later, results of the these treatments were assessed using transect lines and quadrats. A total of 106 species of plants were found; 90 species each study year were within the quadrats, 16 new in 1993, and 16 absent from the 1992 study. Frequency of species and percent cover increased from 1992 to 1993. Dog-fennel (Eupatorium capillifolium (Lam.)) small and eastern baccharis (Baccharis hamilifolia L.) were cover dominants and most frequent in 1992; these two species were most frequent in 1993 with a variety of species cover dominants. Soil analyses indicated that the control plot differed from the plant and Rodeo herbicide plot in higher percent organic matter and sulfur content. The berm area where the trees were burned was higher in phosphorus and potassium than other areas of the plots. The control plot had the most melaleuca regrowth. The fewest melaleuca trees (three) were counted in the study area of Plot 1, which was not treated with herbicide; it is possible that the 1992 high water level in this plot may have prevented tree regrowth. The highest concentration of Velpar L. herbicide treatment plot had 11 trees, the second fewest.
