Southern Flying Squirrel Winter Population vs. Hard Mast Production 12 sites in southeast Ohio Hard mast surveys conducted in September each year (8 sites 2013, 12 sites 2014, 12 sites 2015) Box checks done Oct-Feb & & November-January 2015 To be updated with !!!

Hard Mast Surveys See summary sheet/technical paper for reference If SFS box tree was oak, hickory, or walnut & >10” DBH, then sampled. If not, then found nearest oak, hickory, or walnut >10” DBH within 75 ft. If none…then no estimate made for that SFS box tree site Either one person counted for 60 seconds or two people counted for 30 seconds (each had ‘half the tree canopy) using binoculars.
Previous Slide/Graph Of the 9 sites that were sampled both years 2012 hard mast exceeded 2013 production on 8 of 9 sites (only Rio-URG-Gallia was greater in 2013—but not by much) In most cases 2012 production (based on nuts per tree) was twice as great as 2013
SFS Per Box Per Site VS. Mast Per Tree
Statistics Combining years: regression results were Y= (x) where Y = flying squirrels per box and x = mast per tree R 2 = 0.07, P=0.236 (i.e., not statistically significant)
