  1. Natural Area Teaching Lab Bret Pasch NATL Graduate TA

  2. 60-acre natural area on campus

  3. Wetlands 4 ecosystems located behind UF Cultural Plaza Entomology buildings

  4. Upland Pine Upland pine ecosystem restored (1995-date)As illustrated and described elsewhere, NATL's upland pine ecosystem was choked with laurel oaks in 1995. By 2004, after six prescribed burns and the cutting or killing of hundreds of the invading oaks, the ecosystem was once more hospitable to the germination of the seeds of longleaf pines and the growth of their seedlings. 15 acres 13 being restored since 1995 2 left unburned

  5. Old Field Plots Old-field succession must be periodically interrupted to prevent the succession from reaching its endpoint, i.e., a self-sustaining community (hammock or upland pine in this case). The succession area is subdivided into plots (see map) that will be cleared and cultivated at 1-, 10-, or 40-year intervals. Units with the same period of rotation will be cleared and cultivated out of phase. For example, every five years one of the two 10-year plots will be cultivated. The 1-year plot will be cultivated only during years that none of the other plots is cultivated. This schedule will produce five representative successional states at all times. • 6 acres • 1, 2, 10, & 40 year rotations

  6. Hardwood hammock 21 acres Ephemeral ponds

  7. SEEP-Stormwater Ecological Enhancement Project • Retention basin re-contoured for SEEP (1998) BEFORE

  8. SEEP today Boardwalk trail completed 2008

  9. NATL west academic area • 22 acres closed to public • guidelines available online • Student projects • Short & long–term • Research

  10. NATL east • added in 2005 • 11 acres • ALL academic use only Central marsh

  11. NATL east walkway Completed in March ‘09

  12. Nature trails & kiosks Basic & advanced trail guides Available onsite or online

  13. 1997 2007 50-meter grid& photos Grid-based photographic record of vegetation (1997, 2007-08)In January 1997, a photographic record was made of NATL by taking pictures to the north, east, south, and west at each grid intersection. This was repeated for NATL-west in 2007 and NATL-east in 2008.                                                                                                                                               Looking north from C10 N-S-E-W grid photos

  14. GIS maps & photos online • Grid-based record of soils (2000)Dr. Mary E. Collins All pines mapped! Aerial photos LIDAR Elevation Contours

  15. Species lists online • Surveys of biota (1995-date)Higher plants, vertebrates, and many groups of invertebrates that occur in NATL have been surveyed and the results posted. Gryllus firmus
