What caused the Everglades to shrink?

Today, the Everglades is about the size of New Jersey — half the size it once was. Much of the damage has been caused by humans through water diversion, population pressures, and agricultural run-off.

How did human activities disrupt the Everglades ecosystem?

They have suffered because of boating accidents, vandal attacks, poaching and further habitat destruction. “They are both hunted and many times struck and killed by powerboats, sometimes also swimming into the propellers of boats,” said Scott.

What are two main threats to the Everglades?

Overall THREATS Current threats related to reduced water flows, water pollution and shifting habitat are affecting the health of the site and the amount and quality of habitat. Some of these losses cannot be restored, as habitat features have taken decades to centuries to develop.

How has the Florida Everglades changed over time?

Since 1900 much of the Everglades has been drained for agriculture and urban development, so that today only 50 percent of the origi- nal wetlands remain. Water levels and patterns of water flow are largely controlled by an extensive system of levees and canals.

What are the biggest threats to the Everglades?

The two biggest threats to the Everglades ecosystem are water quality and water quantity. With rapid development on both coasts and an expanding agriculture industry, the human demand for water is increasing rapidly while the supply is not changing.

Why are humans interested in improving the Everglades?

The lack of biodiversity caused by invasive plant species means that humans may lose access to good jobs, and safe water supplies for drinking and farming. So, humans are most likely working to improve the Everglades to protect their tourism industry and water supplies.

What are positive and negative impacts humans have had on the Everglades National Park?

There are positive and negative consequences. Some of the negatives are loss of habitat, water and land in the Everglades. Urbanization has resulted in the loss of a lot of wetland area in the Everglades. Longer hydroperiods in the Everglades ecosystem have a positive effect on aquatic species like the crayfish.

What are threats to the Everglades?

Despite protection of a significant portion of the historic Everglades and recognition as an international biosphere reserve, the ecosystem faces severe threats from the impact of surrounding urban sprawl, ecologically unsound water management, agricultural development, invasion of exotic species, and fire.

What problems are the Everglades facing?

How much has the Everglades shrunk?

Over the last 100 years, the Everglades have shrunk to less than half their original size as agricultural and residential development in the region expands. The process has been accelerated over the last 30 years by the growth of the sugar industry and skyrocketing development of Florida’s east coast.
