Dunes & Maritime Forests

Andrew Sito & Guadalupe Ibarra


Dunes are a terrestrial ecosystem and is mostly and usually made of sand. The sand would be blown away if it hadn't had grass to keep it from moving across the beach. They protect the coast from strong winds and waves that could cause small floods thanks to the grass keeping the sand sturdy. The vegetation may vary due to the storm winds, climate, and soil. It is an important place because sea turtles and shorebirds lay there eggs and because of erosion the population of those animals are rapidly dropping.

Maritime Forests

Maritime forests are in the barrier island ecosystem and is important for many reasons. They stabilize the soil on the barrier island which reduces erosion and that can protect the animals living in the area, it provides hurricane protection from the strong winds and waves, and it provides important habitats for wildlife that only some special animals live on. It is named the barrier island ecosystem because that's what it is, a big barrier that protects the living things on it and near it.

The Bald Eagle

The Bald Eagle is an Apex Predator in that ecosystem. That means that the bird doesn't get hunted by any other animal there and doesn't have to worry about being hunted by other animals.

Positive & Negative Human Impacts


  • We conserve and protect the animals that live there to help keep them from letting them go extinct.
  • Get rid off plants that are destroying the environment

  • We brought exotic species which is a serious problem
  • Coastal Development
  • Cattle Grazing
  • Disruption of Sediment
  • We developed the beachfront which is bad because it causes loss of environment for the animals that live their

Importance of Water in my ecosystem(s)


  • The cacti buds open when it rains to create more cacti.
  • This toad comes out when it's raining and lays eggs. They do this because it's raining


  • Water keeps the animals hydrated so they don't die
  • The water helps plants stay hydrated so that the animals can eat the plants.
  • Keeps amphibians mois so they don't die.

Maritime Forest

  • The plants and grass keep hydrated
  • Rivers have organisms that live in the water that feed the land animals.

LoggerHead Turtle Endangered

The Loggerhead Turtle is an endangered species, although they are the most abundant of all turtles. It is due to pollution, loss of their food, and people messing with their nesting areas that they are so endangered. They primarily eat jellyfish and shrimp and weigh in at about 250 pounds. They are smaller compared to some other ones that can weigh up and over 1,000 pounds. They lay eggs in the sand and cover it back up, after that she leaves the eggs to hatch and lets the turtles live on their own. Once the baby hatches it goes directly out to sea and begins it's life.

Human Impacts for Loggerhead Turtles

Positive Impacts
  • Raise Awareness
  • People clean the beaches
  • Reserve special places on the beach to let the turtles hatch without people or objects in the way
  • Save the turtles by pulling them out of trash when they are stuck
Negative Impacts
  • People go Shrimping and that is what they mostly eat.
  • People put stuff in the way of the turtles eggs and that may cause them to never reach the sea and die.
  • Garbage in the ocean can cause the turtles to get stuck and form with deformities
  • Artificial lighting gets them disoriented when born and will wander around.
