1 Flora & Fauna As it affects the flora and fauna of Virginia’s coastal regions CLIMATE CHANGE

2 Flora & Fauna Virginia’s Six General Categories The Urban Areas The Chesapeake The Coast Lines The Low Lands The Appalachians The Piedmont

3 Flora & Fauna Virginia’s Coastline: A Lot to Lose 112 miles of coastline 4,475 m² of coastal waters 374 m² land lies 5 feet above sea level IPCC conservative sea level rise = 2 feet (2100) Rise could reach

4 Flora & Fauna 90% confidence that anthropogenic fossil fuel burning has increased global mean temperature (IPCC AR4) Ocean surface waters  90% of Earth’s total increased heat uptake (IPCC AR4 Chpt. 5) Increased SST result in thermal expansion and sea level rise Sea level rise will directly impact coastal flora and fauna Premise #1

5 Flora & Fauna Premise #2 90% confidence : observed global warming Atmospheric Warming: - altered regional climates - altered regional climates - increased occurrence of extreme weather - increased occurrence of extreme weather - increased runoff intensity - increased runoff intensity - increased erosion - increased erosion - changes in disease prevalence by region - changes in disease prevalence by region - specific Virginia habitat losses - specific Virginia habitat losses

6 Flora & Fauna Fauna: Potential Impacts Global Warming Leads To… ↑ Drought incidence Sea surface temperature rise Leads To… uninhabitable waters for some ocean species Days above 90°F Leads To… ↑ heat stress ↑ hurricane intensity Leads To… ↑ habitat & food loss ↑ deluge runoff Leads To… alters stream habitats Sea surface rise Leads To… inundated land & inundated fresh water supply Global Warming Leads To… Shifts in prevalence of specific disease

7 Flora & Fauna Fauna: Potential Impacts on Man Sea level rise Leads To… ↓ loss of real estate ↓ loss of farm land ↓ loss of fishery potential ↓ water availability Temperature rise Incidence in VA Leads To… ↑ mosquito-borne disease ↑ power demands in summer ↑ general health stress ↑ costs of food, power, water

8 Flora & Fauna Fauna Specifically: What is at Risk? Fish Species: IUCN red listed Brook Trout Migratory birds: thousands stop in VA marshes Amphibians  flooded/ faster water breeding waters endanger success Reptiles  flooding endangers Fur-bearers  loss of prey species (amphibians, reptiles and birds) endangers

9 Flora & Fauna Non-Agricultural Flora: Potential Impacts Growing season changes - ↑ days above 90 °F - ↑ days above 90 °F - ↑ drought incidence - ↑ drought incidence - ↑ erosion  soil loss  habitat loss - ↑ erosion  soil loss  habitat loss Lost marsh and wetland habitats  local plant extinctionsLost marsh and wetland habitats  local plant extinctions Disease vector habitats alteredDisease vector habitats altered Pollinator and plant seasonal presences  out of syncPollinator and plant seasonal presences  out of sync

10 Flora & Fauna Non Agricultural Flora Specifically: What is at Risk? Loblolly pine Bald cypress Swamp oaks Tapelos Atlantic white cedar

11 Flora & Fauna What Can be Done? Near term Mediation of Impacts Increase living shoreline buffers Restore dune and wetlands Institute measures to limit loss  corridors, land preservation Monitor biodiversity for trends toward loss Consider sea level rise in long term planning of road, home, business, utility construction Consider extreme weather event likelihood in zoning and building code actions Close coal burning plants

12 Flora & Fauna What else can be done? Policy changes: reduce direct impacts Introduce threatened species to new habitats when feasible Initiate a moratorium on building, road and utility construction in low lying areas Develop green energy sources to reduce emissions Cap road construction but expand mass transit

13 Flora & Fauna What More Can Be Done? A Gigaton Saved is a Kilawatt Earned Pass legislation to ban HOA restrictions on clotheslines Regulate lawn mower emissions Restrict median mowing of state roads to areas necessitated by safety concerns

14 Flora & Fauna What Else Can We Do? Recognize True Consumptive Costs Require billing for all energy production, agricultural and commercial externalities to cover all warming adaptation and mitigation costs That is: Tax CO² emissions (~sales tax) for all goods and services with exemptions as needed for low income residents

15 Flora & Fauna The Chesapeake Bay

16 Flora & Fauna The Chesapeake Bay The mouth of the Bay is located near Virginia Beach, Virginia. The Bay extends along almost 100 miles of Virginia’s coastline, fed by the Potomac and Rappahannock rivers.The mouth of the Bay is located near Virginia Beach, Virginia. The Bay extends along almost 100 miles of Virginia’s coastline, fed by the Potomac and Rappahannock rivers. The average depth is a surprisingly shallow 21 ft. This makes the Bay especially susceptible to the impacts of sea-level rise.The average depth is a surprisingly shallow 21 ft. This makes the Bay especially susceptible to the impacts of sea-level rise. It supports over 3,600 species of plants and animals, harbors over one million waterfowl every winter, and is a permanent home to over 29 avian species.It supports over 3,600 species of plants and animals, harbors over one million waterfowl every winter, and is a permanent home to over 29 avian species.

17 Flora & Fauna Potential Impacts An increase in sea-level is not just inevitable for the Chesapeake Bay, it has already been observed. Since 1900, the sea-level has increased by 1 ft, and is predicted to rise another 2 ft by 2100.An increase in sea-level is not just inevitable for the Chesapeake Bay, it has already been observed. Since 1900, the sea-level has increased by 1 ft, and is predicted to rise another 2 ft by 2100. An increase in temperature has also been observed in the area. Since 1960, the temperature has risen by almost 2 o, and is expected to warm another 5 o to 9 o by the end of this century.An increase in temperature has also been observed in the area. Since 1960, the temperature has risen by almost 2 o, and is expected to warm another 5 o to 9 o by the end of this century. It is very likely that an impact of climate change on the Bay would include increased precipitation. This would decrease the water quality by inundating the Bay with nutrients and sediments, while at the same time decreasing salinity.It is very likely that an impact of climate change on the Bay would include increased precipitation.

A significant change of any one of these factors would greatly shift species distribution in the Bay.A significant change of any one of these factors would greatly shift species distribution in the Bay.

18 Flora & Fauna Fauna: What is at Risk? There are over 350 species of fish that call the Chesapeake Bay home. A decrease in salinity from higher precipitation would decrease the number of species that would be able to travel into the Bay from marine environments, who require a certain salinity. The runoff of sediment into the Bay from increased precipitation would also limit the habitat of the abundant freshwater species. (Atlantic/Shortnose Sturgeon)There are over 350 species of fish that call the Chesapeake Bay home. A decrease in salinity from higher precipitation would decrease the number of species that would be able to travel into the Bay from marine environments, who require a certain salinity. The runoff of sediment into the Bay from increased precipitation would also limit the habitat of the abundant freshwater species. (Atlantic/Shortnose Sturgeon) Increased water levels would inundate regions of the Bay, eliminating swamps and marshes that are home to many species of reptile and amphibian. (Red Bellied Turtle)Increased water levels would inundate regions of the Bay, eliminating swamps and marshes that are home to many species of reptile and amphibian. (Red Bellied Turtle) Elevated water levels would limit the habitat of many mammalian species, in addition to pushing them further into the state. Many mammals live the marsh environments of the Bay, and would need to migrate inland to avoid this. (Red Fox, White-tailed deer)Elevated water levels would limit the habitat of many mammalian species, in addition to pushing them further into the state. Many mammals live the marsh environments of the Bay, and would need to migrate inland to avoid this. (Red Fox, White-tailed deer) Many migratory birds inhabit the Chesapeake Bay during the winter, and an increase in temperature would force them out of this region. In addition, many species inhabit the swamp areas, and would need to evacuate their already threatened habitat. (Bald Eagle, Great Blue Heron)Many migratory birds inhabit the Chesapeake Bay during the winter, and an increase in temperature would force them out of this region. In addition, many species inhabit the swamp areas, and would need to evacuate their already threatened habitat. (Bald Eagle, Great Blue Heron)

19 Flora & Fauna Flora: What is at Risk? An increase in temperature from climate change would be detrimental to most, if not all of the many types of underwater grasses in the Bay. Eelgrass is an especially important component to the Chesapeake Bay ecosystem. It provides shelter for many species, and as serves as food for others. Eelgrass prefers the high salinity waters of the lower Bay, so an increase in sea-level or precipitation would limit its environment. An above average stretch of warm weather was experienced in 2005, and as a result huge swaths of eelgrass were killed. Any further increase in temperature would permanently force out this important vegetation.An increase in temperature from climate change would be detrimental to most, if not all of the many types of underwater grasses in the Bay.

22 Flora & Fauna Virginia’s Cities: The Dangers of the Urban Heat Island What is the Urban Heat Island effect? What are the causes of this effect? What are the results of the Urban Heat Island? The demand for air conditioning increases greenhouse gas emissions from power plants Increased days of 100 degrees Devastating effects on surrounding wildlife and plantlife What is the urban heat island effect? by Jane McGrath

23 Flora & Fauna Virginia’s Urban Areas: Some Background 95 counties and 39 independent cities Virginia has 11 Metropolitan Statistical Areas Richmond - population of over 1.2 million people. Virginia Beach - most populous city in the Commonwealth Fairfax County is the most populous locality in Virginia, with over one million residents. Tysons Corner - Virginia's largest office market. Loudoun County - the fastest-growing county in the United States highest median household income: $107,207 (as of 2007) Roanoke - the largest Metropolitan Statistical Area in western Virginia.

24 Flora & Fauna Expansion of Washington, D.C. suburbs into Northern Virginia has created an urban heat island Mostly caused by more absorption of solar radiation in densely populated areas 15 counties received failing grades for air quality - Fairfax County having the worst in the state Effects of Air Quality on Flora and Fauna climate change and urban growth impacts on headwater streams, ecosystem structure and services will be more costly than climate change alone. Premise Virginia's Cities and Towns

25 Flora & Fauna The interaction of climate change and urban growth may entail significant reconfiguring of headwater streams, including a loss of ecosystem structure and services, which will be more costly than climate change alone.

26 Flora & Fauna Fauna Specifically: What is at Risk? When combined with the global warming, urbanization proved devastating to the fish population Fish are widely used indicators of environmental quality NCBI: Forecasting the combined effects of urbanization and climate change on stream ecosystemsNCBI: Forecasting the combined effects of urbanization and climate change on stream ecosystems Journal compilation © 2009 British Ecological Society

27 Flora & Fauna Non-Agricultural Flora: Urban Impacts Urban development… Diminishes the resilience of freshwater ecosystems to climate variability. Storms are sharply increased scours stream banks, decreases the reproductive success of aquatic insects and of fish that lay eggs near the edges of streams increases the input of sediments, nutrients and toxic chemicals into rivers, streams, lakes and estuaries. Sediments reduce water clarity, smother bottom organisms, and clog waterways; excessive inputs of nutrients create toxic chemicals that affect plants and animals. NCBI: Climate change and ecosystems of the Mid-Atlantic Region

28 Flora & Fauna What Can be Done? Encourage Individual Homeowners to… Plant shade trees: reduce your annual heating and cooling costs by an average of 40 percent. Deciduous on the South: loose leaves in Winter; Reflect sun in Summer Convert to compact fluorescent bulbs: Would prevent more than 13 billion pounds of carbon dioxide from being emitted. Become a Green Tag subscriber: Options for homeowners to buy electricity from clean, renewable sources Act locally: Contact your mayor and ask that he sign the U.S. Mayors Climate Protection Agreement, committing your city or town to meet or beat the global warming pollution reductions National Wildlife Federation

29 Flora & Fauna What else can be done? Policy changes: reduce direct impacts “Where land is not already heavily developed, land preservation [programs] could be used to protect headwater streams.” More aggressive efforts to reduce sediment and pollutant loads, Urbanization combined with climate change will be more environmentally costly than either impact alone. Minimizing costs by reassessing the importance of urban streams, as well as the adequacy of [programs] to protect them Proactive policy and/or management actions are needed to advance conservation and should have high priority in future ubranized regions

73 Flora & Fauna What Can be Done? Near term Mediation of Impacts Reduce further deforestation by better development planning try to reduce sprawl Regulate Logging industry enforce real sustainable forestry prevent monocultures Institute measures to limit loss  corridors, land preservation Fund research and monitoring efforts to baselines and trends for biodiversity Consider taxing industrial transportation within and throughout VA Consider extreme weather event likelihood in zoning and building code actions Close coal burning plants

74 Flora & Fauna What Can be Done? What Can be Done? Policy changes: reduce direct impacts Subsidize conversion to sustainable agriculture, which has soon success in some small farms in the regionSubsidize conversion to sustainable agriculture, which has soon success in some small farms in the region Invest in EcotourismInvest in Ecotourism –Recreation and travel –Appalachian Trail –Blue Ridge Parkway –George Washington and Jefferson National Forests Support NGOsSupport NGOs –Western Virginia Land Trust –Sierra Club Cap and trade for CO 2 emissionsCap and trade for CO 2 emissions Imposing taxes on energy usageImposing taxes on energy usage Charging electric at rates that fluctuate to represent production costs.Charging electric at rates that fluctuate to represent production costs.

75 Flora & Fauna What else can be done? Policy changes: reduce direct impacts Streamline the process for species to be granted endangered or threatened status and protection Adequately fund and enforce the Endangered Species Act of 1973 Introduce threatened species to new feasible habitats, so long as this would not further cause environmental damage Develop green energy sources to reduce emissions Wind turbines have already proven to be profitable in nearby regions in Appalachia Cap road construction but expand mass transit

76 Flora & Fauna And What More Can Be Done? A Gigaton Saved is a Kilawatt Earned Pass legislation to ban HOA restrictions on clotheslines Regulate lawn mower emissions Restrict median mowing of state roads to areas necessitated by safety concerns

77 Flora & Fauna What Else Can We Do? Recognize True Consumptive Costs Require billing for all energy production, agricultural and commercial externalities to cover all warming adaptation and mitigation costs That is: Tax CO² emissions (~sales tax) for all goods and services with exemptions as needed for low income residents
