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.

Suggestion:Perhaps a student can digitize the herbarium sheets so we can see them posted here?

For a complete list of many of the species of  algae at Race Rocks scroll down to Chlorophyta, Rhodophyta and Phaeophyta in the Race Rocks taxonomy

Refer to this extended essay on Halosaccion glandiforme with a focus on position on the shore considering height and slope as factors in intertidal zonation

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.
