• Unique geology consists of karst topography with limestone bedrock and numerous springs, sinkholes, and caves
• Extensive coastline stretches over 1,300 miles along the Atlantic Ocean and Gulf of Mexico
  • Barrier islands protect the mainland and provide habitats for wildlife (Sanibel Island, Amelia Island)
• Subtropical climate characterized by warm temperatures, high humidity, and distinct wet and dry seasons
  • Average annual temperature ranges from 65°F in the north to 77°F in the south
  • Annual precipitation varies from 50 inches in the northwest to over 60 inches in the southeast
• Abundant freshwater resources include the Floridan Aquifer, Lake Okeechobee, and numerous rivers (St. Johns River, Suwannee River)
• Rich biodiversity supports a wide variety of plant and animal species, many of which are endemic or endangered (Florida panther, manatee, gopher tortoise)

Historical Context of Florida's Environment

• Pre-Columbian era saw Native American tribes (Calusa, Timucua) living in harmony with the environment, utilizing resources sustainably
• European exploration and colonization in the 16th century led to the introduction of non-native species and the exploitation of natural resources
• 19th-century settlement and development resulted in the draining of wetlands for agriculture and urbanization (Hamilton Disston's drainage projects)
• Early 20th-century conservation efforts began with the establishment of national parks and wildlife refuges (Everglades National Park, 1947)
• Post-World War II population boom and tourism industry placed increased pressure on Florida's ecosystems
  • Rapid urbanization and coastal development led to habitat loss and fragmentation
• Late 20th-century environmental legislation aimed to protect and restore Florida's natural resources (Florida Water Resources Act, 1972; Florida Forever Act, 1999)

Major Environmental Challenges

• Water quality degradation due to agricultural runoff, urban pollution, and saltwater intrusion
  • Nutrient pollution from fertilizers and sewage leads to harmful algal blooms and fish kills
  • Contamination of groundwater and surface water by chemicals and heavy metals
• Habitat loss and fragmentation caused by urban sprawl, infrastructure development, and land conversion
  • Destruction of wetlands, forests, and coastal habitats reduces biodiversity and ecosystem services
• Invasive species introduction and spread, outcompeting native species and altering ecosystem dynamics
  • Examples include Burmese pythons in the Everglades and Brazilian pepper trees in coastal areas
• Climate change impacts such as sea-level rise, ocean acidification, and increased frequency of extreme weather events
  • Coastal erosion and flooding threaten human communities and natural habitats
  • Coral bleaching and die-offs affect marine biodiversity and fisheries
• Overexploitation of natural resources, including overfishing, unsustainable logging, and excessive groundwater extraction
• Human-wildlife conflicts arising from habitat encroachment and changes in animal behavior
  • Increased interactions between humans and alligators, bears, and other wildlife

Human Impact on Florida's Ecosystems

• Urbanization and land development lead to the conversion of natural habitats into human-dominated landscapes
  • Coastal development destroys dunes, mangroves, and seagrass beds, affecting marine life and coastal resilience
  • Sprawling cities and suburbs fragment forests and wetlands, disrupting wildlife corridors and reducing biodiversity
• Agriculture and livestock production contribute to water pollution, soil degradation, and habitat loss
  • Nutrient runoff from farms and ranches causes eutrophication in lakes, rivers, and coastal waters
  • Overgrazing and land clearing for pastures degrade natural grasslands and forests
• Tourism and recreation activities can cause direct damage to ecosystems and wildlife
  • Overcrowding in parks and beaches leads to trampling of vegetation, erosion, and disturbance of wildlife
  • Boating and fishing practices may harm marine life and disrupt aquatic habitats
• Industrial activities and energy production release pollutants into the air, water, and soil
  • Power plants, factories, and mining operations contribute to greenhouse gas emissions and toxic contamination
• Transportation infrastructure, such as roads, bridges, and ports, fragments habitats and alters hydrological patterns
  • Roadkill and wildlife-vehicle collisions are significant sources of mortality for many species

Conservation Efforts and Policies

• Establishment of protected areas, including national parks, state parks, and wildlife refuges
  • Everglades National Park protects the largest subtropical wilderness in the United States
  • Florida's state park system encompasses 175 parks and preserves, covering over 800,000 acres
• Implementation of environmental regulations and management plans
  • Florida Water Resources Act (1972) regulates water use and quality, and establishes water management districts
  • Comprehensive Everglades Restoration Plan (2000) aims to restore the natural flow of water and improve ecosystem health
• Habitat restoration and species recovery programs
  • Florida Panther Recovery Plan focuses on protecting and enhancing panther habitat and reducing human-panther conflicts
  • Coral reef restoration projects involve the propagation and outplanting of coral fragments to damaged reefs
• Invasive species management and control
  • Florida Invasive Species Partnership coordinates efforts to prevent, detect, and control invasive plants and animals
  • Burmese Python Elimination Program incentivizes the removal of invasive pythons from the Everglades
• Public education and outreach to promote environmental awareness and stewardship
  • Florida Master Naturalist Program trains volunteers to educate others about Florida's natural resources
  • Eco-tourism initiatives encourage sustainable travel and support local conservation efforts

Current Environmental Issues

• Everglades restoration faces challenges due to funding limitations, political conflicts, and competing land use interests
  • Balancing water allocation for agriculture, urban development, and ecosystem needs remains a contentious issue
• Red tide and blue-green algae blooms continue to affect coastal communities and marine life
  • Nutrient pollution from agricultural and urban sources fuels the growth of harmful algae
  • Economic impacts include losses in tourism revenue and fisheries productivity
• Sea-level rise and coastal erosion threaten low-lying areas and infrastructure
  • Miami Beach and the Florida Keys are particularly vulnerable to flooding and saltwater intrusion
  • Adaptation measures, such as beach nourishment and seawall construction, are costly and may have unintended consequences
• Invasive species continue to spread and impact native ecosystems
  • Lionfish, a venomous marine predator, has become established in Florida's coastal waters, decimating native fish populations
  • Invasive plants, such as melaleuca and Brazilian pepper, outcompete native vegetation and alter fire regimes
• Freshwater springs, a unique feature of Florida's karst geology, face threats from groundwater depletion and contamination
