Understanding the historic conditions and habitats in a region is a vital first step to planning restoration and management activities. With our partners, US Forest Service, Florida Forest Service, and the Florida Fish and Wildlife Conservation Commission, the Florida Natural Areas Inventory (FNAI) used aerial photography from as far back as the 1930’s, coupled with current photography, soils data, LiDAR elevation data, rare plant occurrences, and GPS’d groundtruthing points, to develop an historic vegetation map of several large contiguous conservation lands in the Apalachicola region. These maps cover a large portion of the region and are an important baseline for ecological and hydrological restoration efforts by managers across property boundaries. Additionally, historic vegetation maps can be used on a smaller scale when planning silvicultural projects, targeting specific habitats for rare plant surveys, or to identify areas where fire has long been absent. This map has been a vital tool when studying rare plant species such as Harper’s beauty (Harperocallis flava). Harper’s Beauty is a critically imperiled, federally endangered plant that is endemic to the Florida panhandle and grows in the species rich pitcherplant prairies of the Apalachicola River lowlands. FNAI has been documenting its populations for more than a decade. Harper’s beauty thrives in a fire dependent habitat that in recent decades has seen a reduction in the fire application and hence an increase of woody vegetation cover and some populations have been reduced or lost. Most recently we established monitoring plots to attempt to quantify its habitat conditions, especially in relation to fire. Preliminary data analysis has provided valuable insight to help guide management.
