What type of succession did we see at Indiana Dunes?
What type of succession did we see at Indiana Dunes?
Plant succession can be seen in the Indiana Dunes as the empty beach transitions to beach grasses, followed by cottonwood, pine trees, and finally the oak forests, which are the climax formation of the dunes!
Are sand dunes primary or secondary succession?
Primary succession
Primary succession occurs in an area that has not been previously occupied by a community. Places where primary succession occurs include newly exposed rock areas, sand dunes, and lava flows. Simple species that can tolerate the often- harsh environment become established first.
How are Indiana sand dunes formed?
Beaches and sand dunes formed along the shores of the lake over 10,000 years ago, as sediments carried by rivers and weathered from the shore by wave action were deposited along the coast.
How are sand dunes primary succession?
Primary succession can happen when bare sand is colonised by plants. Over time, the sand builds up into sand dunes, raising the ground above the height of sea level. Succession in sand dunes is sometimes called a psammosere.
When were the Indiana dunes formed?

Are the Indiana Dunes man made?
The Indiana Dunes are natural sand dunes occurring at the southern end of Lake Michigan in the American State of Indiana.
Is bare sand a primary succession?
Barren Land: Primary succession occurs in an environment that has never supported complex life. Bare rock, lava, or sand don’t contain nutrient-rich soil or nitrogen-fixing bacteria, so plants and animals cannot initially survive.
What leads to primary succession?
Primary succession happens when a new patch of land is created or exposed for the first time. This can happen, for example, when lava cools and creates new rocks, or when a glacier retreats and exposes rocks without any soil. During primary succession, organisms must start from scratch.
Why is sand dune succession important?
As new sand dunes evolve towards heath and pine woodland inland, the ecological succession is called a psammosere. Key ecosystem concepts: Plant succession: dominant species colonising a habitat, changing the features of the habitat, and making it more conducive for other species to colonise and thrive.
