In recent years, Morro Bay’s iconic eelgrass beds, which provide the estuary’s primary living habitat, experienced a massive die-off, declining more than 90 percent since 2007. Efforts to restore the eelgrass have had mixed success in many parts of the bay, and this seagrass is now only found close to the mouth of the bay and sporadically in other regions.

Seagrass systems are found throughout the world and provide many ecosystem services including fish nursery habitats, forage for migratory birds, nutrient cycling, carbon storage and sediment stabilization.

“The loss of eelgrass in the Morro Bay estuary is analogous to the loss of trees in a rainforest,” says lead author and Cal Poly physics Professor Ryan Walter. “Not only do you lose the plants, but you also lose all of the services that they provide for the entire ecosystem.”

    I’m not environmentally educated , but that brings my common knowledge into
    Overdrive in many Educated environmental ideas ,witchery budget busting BS .Morro Bay Estuary is cleaner now then it’s ever been , particularly for the Sewerage that’s been stopped from entering the Estuary , From the Los Osos Septic removals for a new Sewer Plant built in 2006 ..
    Maybe The Eel Grass grew to protect its own Environment in the Estuary from Sewage runoff’s.
    Maybe it no longer needs to protect do to human development..
    Ecological environmentalists can like A Doctor over prescribing medication for a illness that human immune system heals itself of Diseases .
    Stop over reacting as a Ecological hypochondriac…
    My tax dollars don’t like this could be used for human suffering not your Paycheck for playing in the water !!
    Thank you.
