Salt Marsh Transplants in Acadia

Posted by Lucy Zipf

As Caitlin mentioned in the last post, the Primack lab (Amanda, Caitlin, Richard, Abe Miller-Rushing, and I) got together in early June to set up a salt marsh experiment in Acadia National Park in Maine.

The study will test the effect of sea-level rise on growth and reproduction of salt marsh cord grass in low and mid tidal marsh vegetation. We chose two beautiful sites in the park, one in Bass Harbor and one on Thompson Island. We reciprocally transplanted individual plants of the two cord grass species between the low and mid marsh, exposing the mid marsh plants to a higher inundation intended to imitate sea-level rise. Low marsh plants transplanted to the mid marsh will experience a lower inundation comparable to a sea-level fall. We will monitor growth and reproduction in all of our transplants as well as control plots throughout the growing season.

Thanks to everyone for their help with the set up for this study! It involved some hard work and we had a lot of fun.
