Oyster Reef off Lieutenant Island Survives Long,\u00c2\u00a0Harsh Winter<\/em><\/strong><\/p>\n

Turtle Journal returned to the oyster reef restoration project off Lieutenant Island in Wellfleet Bay a few days before the Vernal Equinox.\u00c2\u00a0 This project is spearheaded by Mass Audubon<\/a>‘s Wellfleet Bay Wildlife Sanctuary<\/a> under the leadership of its director, Bob Prescott, in\u00c2\u00a0collaboration with federal, state and town partners.\u00c2\u00a0 While oyster reefs formed a key element of\u00c2\u00a0Wellfleet’s\u00c2\u00a0historic natural coastal ecosystem as\u00c2\u00a0documented by early European explorers, this critical habitat had been eliminated from Wellfleet Bay in modern times.\u00c2\u00a0 Experimenting with methods to\u00c2\u00a0recreate oyster reefs within\u00c2\u00a0the Outer Cape\u00c2\u00a0ecosystem will offer\u00c2\u00a0coastal communities\u00c2\u00a0options to restore\u00c2\u00a0a key underpinning\u00c2\u00a0to their traditional harbor and estuarine ecologies.<\/p>\n

Our Turtle Journal assessment: the rudimentary reef structure\u00c2\u00a0emplaced \u00c2\u00a0last August survived an extremely challenging winter quite well.<\/p>\n

Flashback:\u00c2\u00a0 Oyster Reef in Early Fall 2008<\/em><\/strong><\/p>\n

Last September Turtle Journal cameras probed underwater to capture the experimental reef after its first couple of months.\u00c2\u00a0 These images\u00c2\u00a0provide a good baseline against which to judge its current condition.<\/p>\n

In a September 23rd, 2008\u00c2\u00a0posting on the Wellfleet Bay Natural History Blog<\/a>, Bob Prescott explains why’s and wherefore’s of oyster reef restoration.<\/p>\n

“Why oyster restoration? It\u00e2\u20ac\u2122s not just because they taste great and are increasingly rare in the wild. <\/span><\/em><\/p>\n

Oyster reefs–that\u00e2\u20ac\u2122s what a mass of oysters growing together is called. It is a huge complex structure that is home to many, many species of marine invertebrates and fish, both adults as a feeding area and juveniles to hide in. That habitat is almost completely gone from Wellfleet Harbor.<\/span><\/em><\/p>\n

The ecological services that a reef provides are missing from the harbor ecosystem. Oysters help keep the water clean by pumping 60 gallons of water over their gills every day. Also, they lock up nitrates that are overwhelming the coastal system’s ability to absorb.<\/span><\/em><\/p>\n

We talk about conservation and restoration, right down to the waters edge, but what about all those habitats that we have lost because we overfished them? When an oyster reef is overfished, the shell, the structure itself ceases to exist. No more habitat.<\/span><\/em><\/p>\n

For me, it is about protecting all the habitats that make up this sanctuary and restoring those that are missing or in decline. The oyster reef is one example of a key coastal habitat that needs our help.<\/span><\/em><\/p>\n

In August we began the construction of the new reef near Lieutenant Island in Wellfleet Bay.<\/span><\/em>”<\/p>\n

A later blog entry on November 1st, 2008 explained “How To Build An Oyster Reef<\/a>.”<\/p>\n

Wellfleet Bay Ice Bound, Winter 2008\/2009<\/em><\/strong><\/p>\n

The winter of 2008\/2009 proved quite long and harsh for the Great White North.\u00c2\u00a0 Record snow pelted Cape Cod and ice floes clogged Wellfleet Bay, completely\u00c2\u00a0enveloping the new oyster reef.\u00c2\u00a0 As brief thaws set in, massive ice sheets weighing in the tons were dragged\u00c2\u00a0across the reef like ploughs.\u00c2\u00a0 Bright yellow\u00c2\u00a0marker buoys from last summer were torn from their moorings, and we feared that the reef itself might have been ripped apart.<\/p>\n

Bob Prescott and his team documented ice cover\u00c2\u00a0over the oyster reef in early February.\u00c2\u00a0 If you look closely\u00c2\u00a0at the top left of the ice pack, you may spot a juvenile seal basking in the winter sun (see close-up below).<\/p>\n

Back to the Present<\/span><\/h2>\n

On Saint Patrick’s Day, the Turtle Journal team waded out to the oyster reef at low tide.\u00c2\u00a0 As seen in the image at the top of this post, the reef structure survived the long, harsh winter quite well.\u00c2\u00a0 When Don reached the reef, he frightened away a chubby seagull that had been plucking young, juicy shellfish from the substrate\u00c2\u00a0and slurping down their contents.\u00c2\u00a0<\/p>\n

Young Oysters Survive Harsh Winter on Oyster Reef<\/em><\/strong><\/p>\n

The surf clam substrate still holds a nice set of spat and young oysters.\u00c2\u00a0 Bob’s crack team of oyster researchers will visit the reef shortly to conduct a scientific\u00c2\u00a0assessment of the density of\u00c2\u00a0 shellfish to compare against the data they documented in the\u00c2\u00a0fall.\u00c2\u00a0 They will also begin installing various additional substrates to determine the best structure on which oysters might best\u00c2\u00a0accumulate into a viable, self-sustaining reef within the harsh conditions of the Outer Cape.<\/p>\n

Life Returns to the Oyster Reef<\/em><\/strong><\/p>\n

The water is still pretty cold in the inter-tidal zone off Lieutenant Island.\u00c2\u00a0 So, life is returning slowly as the sun climbs higher into the sky each day.\u00c2\u00a0 Periwinkles and mud snails are moving about now, and pesky, invasive Asian shores crabs have been active all winter under rock fields in front of the western seawall.\u00c2\u00a0 But we were lucky this day to discover a lonely hermit crab strolling along the edge of the reef as an early sign of spring.\u00c2\u00a0 Only yesterday, March 24th,\u00c2\u00a0snow flurries driven by a fierce northeast gale assaulted the Outer Cape.\u00c2\u00a0 In the Great White North, spring comes slow and hard, and must fight its way onto the calendar.<\/p>\n
