With the construction of the Brouwersdam in 1971, the connection between the Grevelingen and the North Sea was closed. As a result the lake slowly turned into a freshwaterlake. This prompted seagrass to explode across the Grevelingen. When however the connection with the Northsea was restored seagrass couldn\u2019t keep up with the fluctuations in salinity, and completely disappeared.<\/p>\n\n\n\n
Now that the conditions in the Grevelingen appear to be a lot more stable for Zostra Marina, we ran a pilot in which we sow seeds. The goal of this pilot was to: 1) see whether plants would grow from a seed 2) if the plants would start to carry seeds themselves 3) if they would spread the next year.<\/p>\n\n\n\n
The seeding was done from a small raft which was attached to one of our boats. On this raft two people laid down. A modified sealant gun was used to inject a mixture of clay and seeds into the the sediment.<\/p>\n\n\n\n
The results will be monitored this year, and should give insight in restoration changes of seagrass in the Grevelingen.<\/p>\n","protected":false},"excerpt":{"rendered":"
