Preliminary Findings

It is almost March 31, 2015 and the end is near for my germination study! Here I show my most recent data on the effect of leaf litter and precipitation on Island Torrey Pine germination time. My findings suggest that the presence of leaf litter has an impact on germination rate and viability of the Island Torrey Pine. This is seen most drastically between drought (LP) years under the presence (+LL) and absence (-LL) of leaf litter.
