Along the Georgia coast, muhly maritime grasslands (Muhlenbergia filipes) are a rare, but vital ecosystem for a variety of wildlife. With rising sea levels and coastal development, this habitat is diminishing along with some of the animals that call it home. Island glass lizards and Eastern diamondback rattlesnakes, both species of conservation concern in Georgia, Eastern kingsnakes, marsh rabbits, and cotton rats are a handful of species that utilize these grasslands for protection and reproduction.

Muhly grass is an early successional plant species, one of the first species to populate secondary dunes. By burning these grasslands, wax myrtle (Morella cerifera) and groundsel (Baccharis sp.) thickets are reduced, and the area covered by grass is increased. Little St. Simons Island uses fire as a management technique, or tool, in an attempt to balance out the loss of these grasslands at other coastal locations.

On February 10 and 11, we partnered with a fire crew from The Orianne Society to burn four grassland locations for Joseph Colbert’s graduate project. Joseph, a Master’s student at the University of Georgia in Dr. Kimberly Andrews’ Applied Wildlife Research Lab, is leading a two-year study on the ecological response to fire in muhly dominant grasslands. He plans on conducting small mammal trail camera surveys, painted bunting point counts, and reptile surveys.

Joseph’s research will aid LSSI and regional conservationists in developing the best management practices for these grasslands.

Early Fall on Little St. Simons

September 22nd was the first official day of Fall, and we’re starting to see the effects here on Little St. Simons Island. The Muhlenbergia (also called Muhley grass) is starting to bloom, the Eastern diamondback rattlesnakes are making more appearances along Beach Road, and the shorebirds are starting migrate in large numbers. Just three days ago, we counted 70 American Oystercatchers, 125 Marbled Godwits, and 211 Black Skimmers–all in one group at Sancho Panza!

Another fall staple is the fallow deer rut. The bucks have full antlers now that they use to mark and defend their territory. Just yesterday, we came across a spotted buck who left behind this excellent example of territorial behavior:

You can clearly see where the buck used his antlers to scrape the ground beneath this tree. He then left his urine for scent and marked the tree as well; can you see all the broken branches?

Fall on Little St. Simons Island is a time of stunning floral and faunal changes. We look forward to sharing these with you over the coming weeks, stay tuned!
