Vegetation Results & Data

Mass Audubon scientists are leading efforts to monitor the vegetation of salt marshes over time, particularly where the Phragmites are growing. Middle and high school students are helping with this monitoring through participating in Mass Audubon’s Salt Marsh Science Project. We are investigating whether Phragmites are spreading in the salt marsh, how fast Phragmites are spreading, and whether the height and spread rate is impacted by different salinity (salt content) levels. 

Vegetación

Científicos Mass Audubon están liderando los esfuerzos para controlar la vegetación de las marismas en el tiempo, en particular cuando los Phragmites están creciendo. Los estudiantes de secundaria y preparatoria están ayudando con este control a través de la participación en Marsh Science Project Sal de Mass Audubon. Estamos investigando si Phragmites se están extendiendo en la marisma, la rapidez con Phragmites se están extendiendo, y si el tipo de altura y propagación se ve afectada por los diferentes niveles de salinidad (contenido de sal).

Data

With the help participating students, we have been collecting data on vegetation as it relates to salt marshes in coastal Massachusetts since 1996. Please note that not all sites are monitored each year. The date range indicates the start date and the most recent year data was collected.
