C and R represent pooled infections from control and restored sites respectively. Numbers listed above the C and R symbols are year post-restoration. Values given in the upper table are total infections and include the double infections listed in the lower table. 

Numbers in this lower table represent the frequency and species composition of double infections observed for each year at control and restored sites. Summary values for total snails, total infected snails, and total infections are given for each year at control and restored sites.
