Mars Hill (MARS)

Mars Hill (MARS)

2003 – present

 

Two long-term demographic plots were established at Mars Hill University, north of Asheville, NC in 2003.  Initial setup was assisted by Scott Pearson, Michelle Hersh, Ted Gragson, Scott Pearson, and others.  From his faculty position at Mars Hill University, Scott has continued to facilitate sampling and logistics.

The two plots are this site are MARS-P and MARS-F.  Both sites are dominated by hardwoods, including Acer rubrum, Liriodendron, Fagus grandifolia, Quercus spp., Carya spp., Fraxinus americana, Acer saccharum, and Nyssa sylvatica.

Only the largest Fagus at MARS-F are reproductive, mast year at right. Circles proportional to tree diameter. Squares proportional to seed rain.

Climate data were obtained here.

Mast data are described in publications, including:
