wetlands filled with peat and acidic water

barriers which restrict water flow

areas devoid of dissolved oxygen needed to support aquatic and marine life

wetlands filled with peat; receive water from groundwater and surface runoff, making them less acidic and more nutrient-rich than bogs

occur near lakes and streams, particularly in areas where heavy rain or snow melt causes seasonal flooding

permanently or seasonally saturated with water

regular pattern of variations in water levels

non-native species which impact the health of wetlands by competing with native species for resources and creating an imbalance in the ecosystem

structures used to stop water from naturally changing course

swamps filled with saltwater; form along coastlines, typically in tropical areas, where seawater floods often

trees which flourish in coastal wetlands

wetland with frequent flooding or constant surface water

Nonpoint Source Pollution

pollution from a widespread source, such as the use of nitrogen and phosphorus fertilizers in agriculture, lawns and gardens

most widespread type of wetland in North America

spongy substance formed by partially decomposed vegetation

Point Source Pollution

coming from a clearly identified source

marshes along coastlines whose water levels are influenced by tides rising and falling throughout the day

enormous wave caused by an earthquake in the ocean; occurs quickly with little to no notice

area which has hydric and anaerobic soil and supports a plant community which is adapted to living in these soils

draining and filling in wetlands to convert them for row crop production, housing, commercial buildings or industrial uses

loss of wetland function resulting from sedimentation, pollution and agricultural runoff

occurs on wetlands, which are already protected or restored to maintain their functions for wildlife and other uses

long-term security of a wetland through a cooperative agreement, conservation easement or regulatory measure

returning a degraded wetland's functions to be more natural

Wetlands

Environmental Science Unit 5

Term	Definition
Anaerobic	free of oxygen
Bogs	wetlands filled with peat and acidic water
Brackish	lightly salty water
Dams	barriers which restrict water flow
Dead Zones	areas devoid of dissolved oxygen needed to support aquatic and marine life
Detritus	dead organic materials
Fens	wetlands filled with peat; receive water from groundwater and surface runoff, making them less acidic and more nutrient-rich than bogs
Freshwater Swamps	occur near lakes and streams, particularly in areas where heavy rain or snow melt causes seasonal flooding
Hydric	permanently or seasonally saturated with water
Hydrogeomorphic Functions	water-retention of soil
Hydrological Regime	regular pattern of variations in water levels
Invasive Species	non-native species which impact the health of wetlands by competing with native species for resources and creating an imbalance in the ecosystem
Levees	structures used to stop water from naturally changing course
Mangrove Swamps	swamps filled with saltwater; form along coastlines, typically in tropical areas, where seawater floods often
Mangroves	trees which flourish in coastal wetlands
Marsh	wetland with frequent flooding or constant surface water
Nonpoint Source Pollution	pollution from a widespread source, such as the use of nitrogen and phosphorus fertilizers in agriculture, lawns and gardens
Nontidal Marshes	most widespread type of wetland in North America
Peat	spongy substance formed by partially decomposed vegetation
Point Source Pollution	coming from a clearly identified source
Swamps	wetlands with woody plants
Tidal Marshes	marshes along coastlines whose water levels are influenced by tides rising and falling throughout the day
Tsunami	enormous wave caused by an earthquake in the ocean; occurs quickly with little to no notice
Wetland	area which has hydric and anaerobic soil and supports a plant community which is adapted to living in these soils
Wetland Conversion	draining and filling in wetlands to convert them for row crop production, housing, commercial buildings or industrial uses
Wetland Degradation	loss of wetland function resulting from sedimentation, pollution and agricultural runoff
Wetland Management	occurs on wetlands, which are already protected or restored to maintain their functions for wildlife and other uses
Wetland Protection	long-term security of a wetland through a cooperative agreement, conservation easement or regulatory measure
Wetland Restoration	returning a degraded wetland's functions to be more natural
