There is great biodiversity in the Macroalgal species at Race Rocks . A herbarium of the species which have been found growing in the reserve is kept in the Biology and Marine Environmental Systems lab at Lester B. Pearson College. These students are floating a filamentous algal form onto a herbarium sheet in a tank of seawater. The algae are then dried between blotters in a drier with heat and circulating air.
Ryan Murphy, former LBPC student returned to Race Rocks to do research for Mt.Allison University on the macroalgal community. He constructed this Digital Herbarium using photographs he took while at the reserve.
