31 FIPR Restoration Workshop April 3, 2008 Emergy Evaluation of Phosphate Mining and Reclamation

32 FIPR Restoration Workshop April 3, 2008 Systems View and Emergy of Mining

33 FIPR Restoration Workshop April 3, 2008 Emergy in Restoration...

35 FIPR Restoration Workshop April 3, 2008 Benefits of Restoration...

36 FIPR Restoration Workshop April 3, 2008 Net Benefits Ratio...

37 FIPR Restoration Workshop April 3, 2008 III. Phosphate Mine Restoration Research 25 years of studying self organization at one level and contributing to it at another...

38 FIPR Restoration Workshop April 3, 2008 No reclamation until 1975 1975 - 1980... pushed dirt around, planted 10% of area in trees, made lakes Success criteria = hide evidence of mining 1980 - 1985…required to reclaim wetlands Success criteria = 400 trees/acre, 80% cover by desirable species, no visible erosion 1985-1995…wetland reclamation, type for type Success criteria = more descriptive, but still counting. 1995- present… Success criteria = more prescriptive..with some numerical criteria Historical Perspective… Reclamation

39 FIPR Restoration Workshop April 3, 2008 Studies of the Interaction of Phosphate Mining and Wetlands 1979-1981 Cataloged wetland responses to mining Evaluated wetland succession on clay settling areas Studied wetland succession

40 FIPR Restoration Workshop April 3, 2008 Seed rain is significantly affected by distance...

41 FIPR Restoration Workshop April 3, 2008 Studies of succession on clay settling areas

42 FIPR Restoration Workshop April 3, 2008 Dry Wet Dry Tree ring analysis suggested that growth rates taper off in about the 20th year, and that variable growth rates result from wet and dry years

43 FIPR Restoration Workshop April 3, 2008 Studies of a Method of Wetlands Reclamation Following Phosphate Mining. 1981-1982 Study of the use of muck from donor wetlands as a innoculum for constructed wetlands.

44 FIPR Restoration Workshop April 3, 2008 The first studies of mucking... ca 1981

45 FIPR Restoration Workshop April 3, 2008 Vegetation growth with differing amounts of applied muck

46 FIPR Restoration Workshop April 3, 2008 Wetland vegetation on mucked plots….

52 FIPR Restoration Workshop April 3, 2008 Biogeomorphology of stream channels... Headwaters - no defined stream channel, broad flow-way, large accumulations of organic soils. Mid-reaches - more defined channel with moderate floodplain moderate accumulations of organic soils Lower reaches - defined channel, large floodplain with natural levies, mineral soils with little or no organic matter.

53 FIPR Restoration Workshop April 3, 2008 Geomorphology of Florida ecosystems….

54 FIPR Restoration Workshop April 3, 2008 Hydrologic regime and hydroperiod of Florida ecosystems

55 FIPR Restoration Workshop April 3, 2008 Vegetative characteristics of Florida ecosystems...

58 FIPR Restoration Workshop April 3, 2008 Ecosystems that develop on mined lands are SOMEWHAT SIMILAR (about 60%) to ecosystems that develop on abandoned agricultural lands..

59 FIPR Restoration Workshop April 3, 2008 Integrated landscape approach to reclamation design….

60 FIPR Restoration Workshop April 3, 2008

61 FIPR Restoration Workshop April 3, 2008 Snags provide bird perches…. The seed rain below perches was from 50 to 100 times that found in areas without perches.

62 FIPR Restoration Workshop April 3, 2008 Successional Trajectories and Nuisance Species in Wetlands 1994-2000 Studied the role of nuisance species Evaluated the function of micro- topographic relief
