Abstract: Restoration of pastures dominated by exotic grasses to the globally outstanding native species diversity of the pine flatwoods ecosystem will aid in the recover of this vanishing community type in the southeast. Understanding how mycorrhizae fungi respond to restoration efforts and mycorrhizae colonization of native pine flatwoods species such as wiregrass, can improve the success of pasture restoration efforts. Symbiotic relationships between plants and arbuscular mycorrhizae fungi are flatwoods plant species including wiregrass, have symbiotic associations with mycorrhizae. Mycorrhizae fungi have proven to play a vital role in prairie restoration, increasing native species cover in plots where inoculum was introduced below sown seeds. Other studies have shown that soil disturbance and fallow treatments significantly reduce mycorrhizae populations. This could have implications for pasture restoration since site preparation consisting of soil disturbance and fallow periods is often required to reduce exotic species. The objectives of the study are: 1) to investigate the effect of pilot upland restoration efforts at The Nature Conservancy’s Disney Wilderness Preserve (DWP, Osceola and Polk Counties, FL) on the mycorrhizae inoculation potential of the soils in the pilot plots and compare those potentials with the soil of adjacent pastures and nearest high quality flatwoods, 2) to determine the differences in mycorrhizae colonization of wiregrass roots in the pilot plots and adjacent flatwoods, and 3) to investigate the effect of site preparation on the MIP of a 98 acre restoration site (compared to its adjacent pasture) and tracking mycorrhizae recovery and change over time. MIP tests will be performed to determine differences in inoculation potential among soil samples taken in the field.
