TRANSCRIPT
EPIC 2004 Update
PREFACE The Environmental Protection Indicators for California (EPIC) project is a collaborative effort of the California Environmental Protection Agency (Cal/EPA), the Resources Agency, the Department of Health Services, and an external advisory group consisting of representatives from business, public interest groups, academia, and local government. The project, led by Cal/EPA's Office of Environmental Health Hazard Assessment (OEHHA), is responsible for developing and maintaining a set of "environmental indicators" for California.
In 2002, the EPIC Project released its first report, Environmental Protection Indicators for California). The report describes the process for developing environmental indicators under the EPIC Project, and an initial set of 84 indicators dealing with air quality, water quality, water supply and use, waste management, pesticides, transboundary issues, human health, and ecosystem health.
As lead agency for the EPIC Project, OEHHA has committed to publishing an update to the indicator report every two years, or as necessary. Although OEHHA no longer has funding for the EPIC Project, a modest level of effort has been devoted to compiling this update, and we are grateful to all who contributed.

DAYS WITH UNHEALTHY LEVELS OF OZONE
The number of days with unhealthy levels of ozone has decreased substantially in most areas of California over the past two decades, with the exception of the San Joaquin Valley, which has seen little improvement. Decreases for most regions were modest during the 1980s but accelerated during the 1990s. Weather is an important factor in the year to year variability in the ambient levels of ozone.

EXPOSURE TO UNHEALTHY OZONE LEVELS
Population exposure to unhealthy levels of ozone – based on duration of exposure and level of ozone pollution – has declined significantly in the South Coast Air Basin. This decline is expected to continue as cleaner vehicles enter the fleet, replacing older ones, and as additional emission controls are implemented. The graph below reflects total annual (population-weighted) exposures to ozone at concentrations above the 1-hour standard (0.09 parts per million), and incorporates both the magnitude and the duration of the average level of exposure to concentrations greater than the standard.

EMISSIONS OF OZONE PRECURSORS – VOLATILE ORGANIC COMPOUNDS (VOC) + OXIDES OF NITROGEN (N0X)
Total emissions of volatile organic compounds (VOCs) and nitrogen oxides (NOx) have been declining over the past 20 years. These pollutants react to form ozone in the atmosphere in the presence of sunlight. Even though motor vehicle miles traveled have increased by 105 percent and population has increased by 43 percent between 1980 and 2000, VOC emissions have declined by 55 percent and NOx emissions by 27 percent during the same period. The greatest declines have resulted from reduction of gasoline vehicle emissions. VOC emissions from gasoline on-road motor vehicles in California have decreased by 69 percent between 1980 and 2000, largely as a result of the state’s on-road motor vehicle emission control program. NOx emissions from gasoline on-road motor vehicles have declined by 44 percent from 1980 to 2000, and are projected to decrease by an additional 52 percent between 2000 and 2010.

DAYS WITH UNHEALTHY LEVELS OF INHALABLE PARTICULATE MATTER (PM10)
Exposure to PM10 has declined or remained stable in most regions of the State. Most of the major air basins have shown a moderate decline in the number of days over the PM10 standard. However, as more particulate monitors were deployed statewide throughout the 1990s, there was a greater potential to record exceedances in previously unmonitored regions. For example, three PM monitors deployed in San Diego in 1993 contributed to that region's increase in days over the standard. Despite the increase in population in urban areas and subsequent increase in vehicle miles traveled, PM10 levels are decreasing within most regions of the State.

PEAK 24-HOUR INHALABLE PARTICULATE MATTER (PM10) CONCENTRATION
Most of the major air basins have shown a moderate decline in maximum 24-hour PM10 concentrations. The increased monitoring enabled by the deployment of additional particulate monitors statewide throughout the 1990s in some cases resulted in higher measured peaks. For example, San Diego added a PM10 monitor at the Otay Mesa border region in 1993; this monitor has recorded the San Diego basin's maximum PM10 levels each year since then. This indicator is also dependent on weather -- secondary particles are more easily formed in the atmosphere during colder winter conditions, while fugitive dust levels are more likely to be higher on dry, windy days. A combination of drought years and high wind events are likely to have contributed to the spikes in PM10 levels in the South Coast and San Joaquin Valley Air Basins in 1990, and in the South Coast Air Basin in 1992.

ANNUAL INHALABLE PARTICULATE MATTER (PM10) CONCENTRATION
Most air basins show moderate declines in annual PM10 levels. In 2002, California’s annual PM10 standard was revised from 30 ug/m3 to 20 ug/m3, and is now calculated as an annual average of quarters instead of the annual geometric mean. All years in the graph have been adjusted to reflect this change. In addition, a new annual PM2.5 standard of 12 ug/m3 was adopted. Because PM2.5 monitoring did not begin until 1999, trend data for PM2.5 are not shown.

DAYS WITH UNHEALTHY LEVELS OF CARBON MONOXIDE
Days with unhealthy levels of carbon monoxide have decreased dramatically throughout the State. The Los Angeles area, which is part of the South Coast Air Basin, has been the only major urbanized area with any unhealthy days since the mid-1990s. Los Angeles now qualifies for attainment, and had only one day above the standard in 2001 and 2002.

PEAK 8-HOUR CARBON MONOXIDE CONCENTRATION
Peak 8-hour carbon monoxide levels have declined and have remained well below the State 8-hour standard (9.0 ppm) since the mid-1990s in all urban areas except the South Coast Air Basin. Only the Los Angeles County portion of the South Coast Air Basin and Calexico in Imperial County (not shown on the graph) exceeded the standard in 2002. Compared to previous years, the South Coast experienced only one day above the standard in 2001 and 2002, and now qualifies for attainment.

CARBON MONOXIDE (CO) EMISSIONS
Total emissions of carbon monoxide have been declining over the past 20 years, primarily due to gasoline vehicle emission reductions. Even though motor vehicle miles traveled have increased by 105 percent and population has increased by 43 percent between 1980 and 2000, the adoption of more stringent motor vehicle emissions standards has contributed to a 65 percent decline in statewide carbon monoxide emissions from on-road motor vehicles during the same period. With continued vehicle fleet turnover to cleaner vehicles and the incorporation of cleaner burning fuels, carbon monoxide emissions are forecast to continue decreasing through the year 2010.

HOUSEHOLD EXPOSURE OF CHILDREN TO ENVIRONMENTAL TOBACCO SMOKE (ETS)
There has been a steady increase in the number of households with children under 18 where smoking is prohibited. Environmental tobacco smoke (or second-hand smoke) is a major toxic indoor air contaminant and is of particular danger to the young. For infants and children, the single most important location for ETS exposure is the home. This indicator is based on yearly statewide surveys, and provides an approximation of infant and child exposure to ETS in the home.

AQUATIC LIFE AND SWIMMING USES ASSESSED
The pie charts below reflect assessments for 2002 of the extent to which surface water bodies support two beneficial uses: aquatic life and swimming. This indicator is probably more influenced by changes in the assessment approach and availability of monitoring data than actual improvement or degradation of water quality. The quality of the data used, changes in the water body assessment database, and the lack of a comprehensive effort to monitor and assess these waters make it difficult to draw conclusions regarding water quality trends in California.

SPILL/RELEASE EPISODES -- WATERS
From 1997 to 2001, spills reported to the Office of Emergency Services (OES) increased approximately 70 percent, although reported incidents decreased approximately 10 percent from 2001 to 2002. Spills of sewage, petroleum and other materials to water generally cause temporary conditions of pollution or nuisance.

LEAKING UNDERGROUND FUEL TANK (LUFT) SITES
From 1985 to 1995, the number of LUFT sites increased significantly. This was likely due to increased monitoring and leak detections as a result of increased regulatory attention, such as tank upgrade activities. The trend peaked in 1995 and is now steadily decreasing. The decrease is attributed to the closure of numerous sites where the source of contamination was removed, and the remaining contamination did not pose a threat to human health. Currently, with nearly all active tanks having been upgraded, the total number of LUFT sites should continue to decline. The number of LUFT sites located within 1,000 feet of a public drinking water source has generally followed the same trend as the total number of sites.

DRINKING WATER SUPPLIES EXCEEDING MAXIMUM CONTAMINANT LEVELS (MCLS)
Approximately 15,000 groundwater and 1,000 surface water sources of drinking water in California are regularly monitored for compliance with drinking water standards known as maximum contaminant levels (MCLs). Monitoring results show a slight decrease in the number of drinking water sources with first-time detections of contaminants at concentrations greater than the MCLs from 1996 through 2000 (1994 and 1995 data include some sources with detections from prior years). Increased detections in 2001 and 2002 likely reflect changes in data reporting, rather than increased contamination. [New requirements required laboratories to report analytical data directly to the Department of Health Services (DHS). This resulted in the reporting of data for small water systems regulated by local primacy agencies -- usually county health departments -- that had previously not been submitted to DHS]

COASTAL BEACH AVAILABILITY – EXTENT OF BEACHES POSTED OR CLOSED
Coastal beaches are posted or closed when certain kinds of bacteria are found in the water at levels considered unsafe for swimming. Beach closures are most commonly the result of sewage spills. Beach postings have remained relatively constant from 1999 (when weekly bacterial testing began) to 2003. The increase in BMDs of closures in 2003 is primarily the impact of urban runoff and sewage flowing from Mexico. BMDs of permanent postings have yet to be accurately measured. A constant value is used as a placeholder until better information can be developed.

BACTERIAL CONCENTRATIONS IN COMMERCIAL SHELLFISH GROWING WATERS
The average fecal coliform bacteria concentrations in approved commercial shellfish growing waters during periods of harvesting continue to be maintained within the regulatory standard of 14 MPN (most probable number)/100 mL. An additional site, Agua Hedionda Lagoon, is added to the indicator for this update; samples from this site showed higher fecal coliform concentrations than at the four other sites.

FISH CONSUMPTION ADVISORIES - COASTAL WATERS
Data generated by the Coastal Fish Contamination Program for additional bays/estuaries were assessed in 2004. While this resulted in an increase in the total acreage of bays and estuaries assessed, it did not result in a change in the extent of bays and estuaries where fish can safely be eaten once a week by the general population. In addition, a reevaluation of assessed acreage found that total assessed acreage had been previously undercounted. This has been corrected in the figure below. The significant drop in 1995 in the number of acres where fish are known to be safe to eat is due to multiple factors, including the availability of data for additional contaminants and additional fish species for the same water bodies, and the use of more conservative toxicity criteria based on new toxicological information. Hence, the decline may not necessarily reflect increased water or fish tissue contamination over the period of time in question.
No additional coastline data were assessed, hence no update is presented for “Miles of coastline where fish are known to be safe to eat” (see page 91 of the 2002 EPIC Report). Sampling by the Coastal Fish Contamination Program ended in 2003 with the loss of program funding.

In average water years like 2000, California receives about 200 million acre-feet of water from precipitation and imports from Colorado, Oregon, and Mexico. Of this total supply, about 50 to 60 percent either is used by native vegetation, evaporates to the atmosphere, provides some of the water for agricultural crops and managed wetlands (effective precipitation), or flows to Oregon, Nevada, the Pacific Ocean, and salt sinks like saline groundwater aquifers and Salton Sea. The remaining 40 to 50 percent (denoted as dedicated supply) is distributed among urban and agricultural uses, used to protect and restore the environment, or stored in surface and groundwater reservoirs for later use. In any year some of the dedicated supply includes water that is used multiple times (reuse) and water stored from previous years. Ultimately, about a third of the dedicated supply flows to the Pacific Ocean (in part to meet environmental requirements) or to other salt sinks.
In wet and drier years, like 1998 and 2001, respectively, the total supply and the distribution of the dedicated supply to various uses differ significantly from the example above for an average year. For more information on the state's recent water supplies and uses, see the California water summary in Volume 3 Regional Reports.
Through an ongoing collaborative process, the California Water Plan Update develops statewide and regional water balance information and forecasts which are published every five years. Some findings from the California Water Plan Update 2004 are as follows:
• Advances in water conservation and recycling, combined with infrastructure improvements and new storage facilities, have reduced and met the additional demands of a growing population. Cities use about the same amount of water today as they did in the mid-1990’s, while accommodating 3.5 million more people.
• Most agricultural water demands are met in average water years. However, in some areas, agricultural water is transferred to urban uses, environmental restoration, and groundwater replenishment. Even in average water years, some growers forego planting and other agricultural operations because they lack a firm water supply. Over the past 25 years, farmers have learned to grow 50 percent more crops per acre-foot of water by improving productivity and efficiency.
• Although more water is dedicated today to restore ecosystems, some environmental requirements are not always met. Further, we do not fully understand ecosystem needs and their response to flows.
• California relies on over-pumping its groundwater basins, a practice that reduces available water supply, increases pumping costs, and in some areas, degrades groundwater quality. In many areas, surface and groundwater contamination from natural and human sources has effectively reduced the water supply that can be used.

WATER USE EFFICIENCY – RECYCLING MUNICIPAL WASTEWATER
Between 2000 and 2002, there has been a 30 percent increase in the amount of treated municipal wastewater that was recycled. In 2002, 525,000 acre-feet of wastewater were recycled, which is more than 50 percent of the State goal for 2010.

STATEWIDE SOLID WASTE GENERATION, DISPOSAL AND DIVERSION, PER CAPITA
Per capita disposal of solid waste has decreased, even as generation has increased. This is due to a sharp increase in diversion. The statewide diversion rate has increased from 10 percent in 1989 to 47 percent in 2003. Diversion involves recycling, composting and reduction in waste generation. Recent increases in generation and disposal may reflect an economy more dependent than ever on construction activities.

NUMBER OF TIRES DIVERTED FROM LANDFILLS
Over the past 12 years, the quantity of tires that have been recycled or reused in some manner has increased while those disposed of at landfills has decreased. For the year 2002, California was challenged with responsibly managing 33.5 million reusable and waste tires entering the waste stream. The California Integrated Waste Management Board estimates that more than 25 million tires (74.9 percent) are diverted annually for various alternative uses, including reuse, re-treading, recycling, and combustion. The remaining 8.4 million tires are shredded and disposed of in California's permitted solid waste landfills, stored at permitted sites, or illegally disposed of around the State. In addition, an estimated two million waste tires are stockpiled throughout the state, posing a health and safety risk to the public.

HAZARDOUS WASTE SHIPMENTS
The total amount of hazardous waste shipped for treatment, storage and disposal has fluctuated over the past decade, with the lowest amounts shipped in 1996 and 1997, and the highest in 2001. Over the same ten-year period, recurring hazardous waste (i.e., hazardous wastes generated in the course of commercial or industrial operations) shipments have shown a similar trend, peaking in 2000. Recurring wastes have made up 63 to 77 percent of the total amount of hazardous wastes shipped. Shipments of cleanup wastes -- which include wastes containing polychlorinated biphenyls (PCBs) and asbestos, and hazardous wastes generated following site cleanups – have increased since 1996, with a peak in 2001.

HAZARDOUS MATERIAL INCIDENTS
Releases, spills or other incidents involving hazardous materials can pose an immediate and direct threat to humans and the environment. State law requires all significant releases or threatened releases of hazardous material be immediately reported to the Governor’s Office of Emergency Services (OES). Since 1993, the number of such incidents reported to OES has fluctuated from year to year between approximately 5,200 to 7,500. Likewise, the number of transportation-related hazardous material incidents has fluctuated between approximately 900 and 1,400 a year. The latter are based upon Hazardous Material Incident Reports submitted by shippers or transporters of hazardous materials.

HAZARDOUS WASTE DISPOSAL
This indicator is based on data from hazardous waste manifests that must be prepared for each shipment of hazardous waste. Most hazardous waste shipped offsite is destined for disposal in landfills, or for recycling. The amount of hazardous waste disposed in landfills has fluctuated over the past ten years, but has increased overall; the amount recycled has increased slightly over the same period of time. The percentage of hazardous wastes shipped with manifests that did not specify a disposal or treatment method has declined significantly, while trends for other methods have remained relatively stable.

SOIL CLEANUP
The volume of contaminated soil and other solids cleaned up at hazardous waste sites continues to fluctuate from year to year. (Note: Data were not routinely entered into the database used to track contaminated sites until fiscal year 1996/97.) Treatment or removal of contaminated soil may be influenced by the availability of resources, both within the regulatory agency having jurisdiction over the contaminated site, as well as the party responsible for cleanup. Other factors that influence soil cleanup or removal include prevailing policies, available treatment technology, and site-specific characteristics.

CONTAMINATED SITES
The number of contaminated sites in California has remained relatively stable at about 350 sites since the 200-2001 fiscal year. A contaminated site is a property where the release of one or more hazardous substances has been confirmed by the Department of Toxic Substances Control (DTSC), including military facilities, legacy sites (with historical contamination or naturally occurring hazardous materials such as asbestos), and sites on the federal National Priority, or “Superfund” List. Contaminated sites at currently permitted facilities are not included.
An “active site” is one that DTSC is actively working to remediate, and is generally a high priority, high potential risk sites. A “backlog site” is one which is not currently under investigation or remediation. Backlog sites have made up twenty percent or less of all contaminated sites in the past six years.

AREA WITH PESTICIDES DETECTED IN WELL WATER
The land area where pesticide use is regulated by the Department of Pesticide Regulation (DPR) following pesticide detections in well water samples has steadily increased since 1988. As of 2003, this area totaled approximately 560 square miles. However, the rate at which new sections of land have been added has decreased in recent years.
This lower rate is related to a decrease in the number of wells sampled annually by DPR (see second graph). The number of wells sampled and the spatial coverage have varied annually in relation to budgetary constraints. Pesticide residue detections are influenced by lower detection limits and patterns of pesticide use. Because DPR targets vulnerable areas for sampling, a large proportion of the wells has detections of pesticide residues. New regulations enacted in 2004 will increase the regulated land area to approximately 4,000 square-miles with vulnerable areas determined by similarity of soil and depth to groundwater conditions as compared to those contaminated areas indicated in the first graph.

SIMAZINE AND BREAKDOWN PRODUCTS IN A MONITORING NETWORK OF 70 WELLS IN FRESNO AND TULARE COUNTIES
Concentrations of simazine and its breakdown products have been stable in 70 domestic wells monitored in Fresno and Tulare Counties since the inception of monitoring in 1999. Detections of simazine have not exceeded the drinking water standard or maximum contaminant level (MCL) of 4 parts per billion. Simazine breakdown products, however, were found at higher concentrations; the total residue concentration of simazine and its breakdown products in some wells have exceeded the MCL each year. This indicator will be used to measure the effect of new regulations developed to modify pesticide use.

PERCENT OF PRODUCE WITH ILLEGAL PESTICIDE RESIDUES
From 1998 through 2003, less than 2% of produce samples had illegal pesticide residues. Of these, less than half a percent exceeded allowable levels (tolerances); a higher proportion contained residues for which allowable levels of the pesticide have not been established for the produce in which it was found.

NUMBER OF REPORTED OCCUPATIONAL ILLNESSES AND INJURIES ASSOCIATED WITH PESTICIDE EXPOSURES
Although an increase in reported occupational pesticide illness and injury occurred in 2002, the overall trend continues to decline over the past 14 years. The increase in 2002 cases is the result of a few incidents in which a large number of people were exposed, primarily to offsite movement of pesticides or their breakdown products.

CARBON DIOXIDE EMISSIONS
Greenhouse gases in the atmosphere retain heat radiated by the earth’s surface back towards space. Such gases are emitted from both natural and anthropogenic sources (including carbon dioxide, methane, and nitrous oxide), and synthetic chemicals (including hydrofluorocarbons). Carbon dioxide emissions from the combustion of fossil fuels account for about 75% of greenhouse gas emissions. Emissions have increased nearly 30% since 1970. However, emissions have been decreasing, on both a per capita and a per $1,000 gross state product basis.

AIR TEMPERATURE
Air temperatures have increased over the past 90 years. Counties with large populations (over one million residents) had the highest temperature increase; those with populations less than 100,000 had the smallest increase. Large urban areas are generally warmer than rural areas, likely due to the “urban heat island” effect. Temperatures in coastal areas can be moderated by sea surface temperatures. Efforts are underway to collect data in a manner that will provide a better understanding of factors affecting temperature.

ANNUAL SIERRA NEVADA SNOWMELT RUNOFF
Average spring snowmelt from the Sierra Nevada into the Sacramento River has decreased by about 12 percent since 1906. Spring snowmelt runoff is presented in the graph below as the percentage of total runoff for the “water year” (October through September) that occurs during the spring and early summer (from April through July). This indicator provides a measure of temperature-related snowmelt runoff patterns into the Sacramento River. Heavy snow pack accumulates in the Sierra Nevada each winter. Spring warming causes snowmelt runoff, which generally begins in April and runs through July.
If winter or spring temperatures are unusually warm, more rain falls instead of snow, thus the later snowmelt runoff contains lower water volumes. In addition, increased winter flooding would also lower the snowmelt runoff percentage. The decrease in snowmelt, especially after 1950 is likely due to increased air temperatures and climate changes. Other factors, such as the Pacific Ocean sea surface temperature pattern oscillations, solar radiation, and air pollution probably contribute to the patterns observed.

SEA LEVEL RISE IN CALIFORNIA
Sea level rise provides a physical measure of possible oceanic response to climate change. This indicator shows the rising trend in sea level measured at two California stations: San Francisco and La Jolla. Long-term data from 10 of 11 California stations show increases in sea level at varying rates. The rise in global sea level is attributed to the melting of mountain glaciers and ice sheets around the globe and the thermal expansion of ocean water. Sea level rise is not a new phenomenon, having been a major natural component of coastal change throughout time. Differences in sea level rise along the coast can occur because of local geological forces, such as land subsidence and plate tectonic activity. However, there is concern that the rate of sea level rise may increase with possibly increased global warming.

AIR POLLUTANTS IN THE CALIFORNIA-BAJA CALIFORNIA BORDER REGION
Cross-border air quality monitoring has been conducted in the San Diego/Tijuana region since 1995, and in Calexico/Mexicali since 1997. Data from these monitoring stations show that peak concentrations of inhalable particulate matter (PM10), ozone and carbon dioxide continue to exceed California air quality standards in the border region. Peak concentrations of nitrogen dioxide have remained below the California standard since 2000.
In the graphs that follow, data from Baja California monitoring sites are shown in teal, and data from the most comparable California sites shown in orange. Data for a monitoring station in Los Angeles are presented (dashed black line) to provide perspective
Inhalable particulate matter (PM10). PM10 pollution continues to be a widespread problem in areas south of the border and the immediately adjacent California areas. Peak concentrations for most sites, with the exception of Calexico, show a slight decline or have remained relatively stable, but most are still well above the State standard. Higher than usual PM10 concentrations at Calexico-Ethel from 2000 to 2002 were probably caused by an increase in dust producing activities in the area combined with high wind events. The peak observed at Tijuana-La Mesa in 2001 was apparently caused by an episode of increased residential burning during the winter holiday season.

Carbon monoxide. The Calexico-Mexicali region continues to exceed the State CO air quality standard, but a strong downward trend at Calexico indicates that the area may be nearing attainment. This downward trend can probably be attributed to the introduction of unleaded gasoline in Mexicali in the mid-1990’s, which prevents the deterioration of catalytic converters in cars, and the introduction of newer, less polluting vehicles as part of the normal fleet turnover. All the other sites for which complete data are available show attainment of the State standard.

LAND MANAGEMENT IN CALIFORNIA
Changes in land management can have significant impacts on the integrity of the ecosystem. The two key characteristics of land management are ownership (private vs. public) and use. Land management defines the land owner’s primary objective, a key factor in determining compatibility with, and flexibility for maintaining ecological integrity. Changes in land management and use can have significant impacts on the integrity of the ecosystem.

CLARITY OF LAKE TAHOE
Water clarity is an indicator of the health of a lake. It is measured by the depth that a round disk (called a Secchi Disk) can be seen when lowered into the lake. Lake Tahoe clarity has decreased (about an average of one foot per year) since the late-1960’s. Data from 2001 and 2002 show a slight increase in clarity, likely due to decreased water inflows that lessened sediment and nutrient loads. Annual average clarity decreased again in 2003, but the change was within the inter-annual variation in Secchi depth.

STATUS OF CENTRAL VALLEY CHINOOK SALMON POPULATIONS
In the past few years, spawning returns of all runs of Central Valley Chinook salmon have improved, in part due to favorable ocean conditions. The Sacramento River winter-run Chinook salmon population has increased in recent years relative to extremely low levels in the early 1990’s. However, the population remains well below the proposed level defined for recovery of this endangered run. Populations of the threatened spring-run Chinook salmon have shown some recovery in recent years; this recovery has been associated with numerous factors, including favorable ocean conditions, removal of diversion dams, installation of fish screens, instream habitat and flow improvements, and improved watershed management. Fall-run Chinook salmon populations have increased since the late 1990’s; however, populations of this run are significantly influenced by hatchery production and therefore may be relatively poor indicators of ecosystem health.

CALIFORNIA LEAST TERN POPULATIONS
The population of the least tern, which is on the federal and State lists of endangered species, has increased since 1970, although production of young has been relatively poor since the late 1990s. The record-high total of 6,688 pairs reported in 2003 was more than twice the average annual breeding population size during the mid 1990s. Since much of tern nesting habitat is disturbed by humans, these birds need to be monitored closely in the future.

WILDFIRES IN FORESTS AND GRASSLANDS
Fire plays an integral role in regulating the spatial pattern, composition, and structure of California’s natural resources. Many California ecosystems depend on a particular fire regime for long-term health. Disruption of these natural cycles often has significant ecological ramifications for ecosystem structures, functions, and capabilities to provide for human needs. In general, the annual acreage burned over the last fifty years has been highly variable. This high variation would appear to be largely related to climate, where periods of significant drought are associated with large area burned years. Over the past five decades, wildfires in brushlands and grasslands have been more common than wildfires in forested areas, while lands in public ownership began burning more frequently than private lands around 1970 (see graphs in the EPIC report, link provided below).

CONVERSION OF FARMLAND TO URBAN AND OTHER USES
Farmland has been lost to urban development, removed from active use, or used for environmental restoration purposes. Prime farmland and grazing land have been the source of the majority of farmland conversions. “Additional cultivated land’ includes non-prime agricultural land. “Other” refers to low density rural residential, mined lands, and related uses. Between 2000 and 2002, prime farmland accounted for 21% of the 92,750 new urban acres, and other irrigated farmland categories comprised an additional 8% of new urban land.

ECONOMY
In 2001, California’s gross state product (GSP) was estimated to be over $1.3 trillion, accounting for 13 percent of the nation's output. The State’s economy trails only the United States (as a whole), Japan, Germany, and the United Kingdom. Our nation's next largest state economy—New York—is about 60 percent the size of California's.

ENERGY CONSUMPTION
From 1985 to 2000, total energy consumption in California increased by about 28 percent, while the economy, as measured by the gross state product (GSP), increased by more than 150 percent; the second graph illustrates a continuing downward trend in the amount of energy consumed per unit of GSP. The transportation sector continues to be the largest consumer of energy in California, followed by the industrial sector

TRANSPORTATION
The number of vehicle miles traveled and the volume of fuel consumed by motor gasoline vehicles continue to increase, the latter at a relatively slower rate (particularly after 1990). For diesel-fueled vehicles, the trends have remained relatively unchanged over the past 13 years.
The average transportation fuel efficiency for motor gasoline vehicles has improved to 19.4 miles per gallon in 2003, while remaining relatively unchanged for diesel vehicles.

INFANT DEATH RATE
The infant death rate (the number of deaths among infants under one year old per 1,000 births) in California continues to decrease. In 2001, there were 2,815 infant deaths and 527,371 live births, for an infant death rate of 5.3 per 1,000 live births. Nationally, the infant death rate in 2001 was 6.8.

ASTHMA PREVALENCE AMONG ADULTS
A state-based survey of individuals aged 18 and over reported that, from 2000 to 2002, lifetime asthma prevalence increased from 11.5 to 12.7 percent, and from 10.5 to 11.8 percent in California and in the United States, respectively. During the same period of time, current asthma prevalence decreased from 7.3 to 6.4 percent in California, and increased from 7.2 to 7.5 percent nationally. In 1980, the annual prevalence of self-reported asthma in the U.S. population was estimated to be 31.4 per 1,000 (or 3 percent).
“Lifetime prevalence” is determined by “yes” responses to the question, “Have you ever been told by a doctor that you have asthma?” “Current prevalence” is determined by a “yes” answer to the same questions, as well as to the question, “Do you still have asthma?”
