Pine Island Sound facts for kids

Pine Island Sound, January 2016

Pine Island Sound is a large, shallow body of water in Lee County, Florida. It lies between Pine Island and several barrier islands. These islands include Sanibel Island, Captiva Island, North Captiva Island, and Cayo Costa. They help separate the Sound from the Gulf of Mexico.

Pine Island Sound connects to other important waterways. To the north, it links with Gasparilla Sound and Charlotte Harbor. To the south, it joins San Carlos Bay and the Caloosahatchee River.

The Sound is part of the Pine Island Sound Aquatic Preserve. This protected area was created in 1970. It covers about 190 square kilometers (54,000 acres) of underwater land.

Amazing Habitats of Pine Island Sound

Pine Island Sound is home to many important natural areas. These habitats provide food and shelter for countless animals.

• Mangroves: These special trees grow in salty water. Their tangled roots offer safe places for young fish and crabs.
• Seagrass Beds: Underwater meadows of seagrass are vital. They are a main food source for manatees and sea turtles.
• Salt Marshes: These grassy wetlands are flooded by tides. They act as nurseries for many marine creatures.
• Oyster Communities: Groups of oysters form reefs. These reefs help filter the water, keeping it clean.
• Tidal Flats: These muddy or sandy areas are exposed at low tide. They are feeding grounds for many birds.
• Sponge Beds: Sponges attach to the seafloor. They filter water and provide homes for small organisms.

Red Tide and Its Effects

Sometimes, tiny living things called dinoflagellates grow very quickly in the water. This is known as a red tide. The specific type found here is Karenia brevis.

Red tides can affect all animals in Pine Island Sound. This includes mollusks, fish, birds, and even mammals. Scientists study red tides to understand how they impact the environment.

Boating and Water Safety

Pine Island Sound is quite shallow in many places. Because of this, boaters need to be careful. It is important to use up-to-date maps and tide tables. This helps boats avoid getting stuck or damaging the sensitive seafloor.
