“…A 2007 estimate suggests 1.3 million acres of California forestlands are at moderate to high risk of impacts from ozone (Campbell et al, 2007). Three air basins are predominantly affected, corresponding to the southern Sierra, South Coast, and Mojave bioregions.…”

Acknowledgements in 1979, and 2003. In 2008, the Federal Farm Bill added a provision to federal law that required states to do assessments of forest resources. These assessments are to identify key issues and define the status and trends across all forest lands in each state. To the extent possible, spatial areas (called priority landscapes) are to be delineated that help focus investments and other programs to deal with associated issues. A separate document must also be prepared that presents strategies to address issues and priority landscapes identified in the assessment. The intent of the 2010 Forest and Range Assessment is to meet both the state and federal mandates, hence it covers both forest and rangeland resources, on private as well as publically managed lands.In many ways, this assessment portrays a continuation of past trends of impacts from wildfire, development, forest pests, and exotic invasive species. However, there are also relatively new or markedly increasing potential threats from renewable energy infrastructure, off highway vehicle use, and climate change. Finally, traditional as well as new opportunities exist for shaping future conditions through emerging markets for biomass and other renewable energy sources; carbon, niche markets, and ecosystem services; innovative regional and local partnerships and strategies to conserve and manage open space and working landscapes for both commodity production and non-market benefits; and various tools, policies, programs and incentives to positively influence land management and use decisions. PRESENTATION OF THE 2010 ASSESSMENT SUMMARY OF CHAPTER RESULTSKey findings and highlights from each topic covered in this assessment are supplied in this section, organized according to the guidance given by the Forest Service's Redesign program. These highlights do not cover the topics in detail, but provide a quick review of topic coverage to serve as a supplement to the strategy report. ASSESSMENT California's Forests and Rangelands 6 CHAPTER OVERVIEWMany of the same ecosystems that have been hard hit by historical development are projected to be further impacted by development in the near future, particularly in and around the largest urban areas. The state's already large population is still growing, particularly in Southern California, and an estimated 3.9 million residents will be added over the next decade. This ongoing trend will maintain or increase pressure for land development that can increasingly compromise ecosystems across the state.Tools to address development threat to ecosystems, include land acquisition, easements, zoning policies, and policies to promote in-filling of existing developed areas.This chapter has a single spatial analysis which examines the threat of near-term development to ecosystems. Key Findings CHAPTER OVERVIEWThe concept of "working landscapes" was developed to encompass the idea that lands used for commodity production also provide crucial ecosystem services and that future demands make it essential that these system...

“…At every site, the amount and severity of injury to the foliage of ozone-sensitive plants is used to formulate a plot-level injury index referred to as the ozone biosite index or BI (Smith et al 2007). A national ozone risk map generated every year using a rolling 5-year average of the BI, is applied to tree growth data to estimate the volume of sensitive tree species and the area of forest land at risk of ozone impact (Campbell et al 2007;Coulston et al 2003;Rose and Coulston 2009;Woodhall et al 2010). Analytical procedures and risk assessment have been fully described elsewhere (Smith et al 2008).…”

The US Forest Service administers a long-term, nationwide ozone biomonitoring program in partnership with other state and federal agencies to address national concerns about ozone impacts on forest health. Biomonitoring surveys begun in 1994 in the East and 1998 in the West provide important regional information on ozone air quality and a field-based record of ozone injury unavailable from any other data source. Surveys in the Northeast and North Central subregions cover 450 field sites in 24 states where ozone-sensitive plants are evaluated for ozone-induced foliar injury every year. Sites are typically large, undisturbed openings (>3 acres in size) close to forested areas where >3 bioindicator species are available for evaluation. Over the 16-year sampling period, injury indices have fluctuated annually in response to seasonal ozone concentrations and site moisture conditions. Sites with and without injury occur at all ozone exposures but when ambient concentrations are relatively low, the percentage of uninjured sites is much greater than the percentage of injured sites; and regardless of ozone exposure, when drought conditions prevail, the percentage of uninjured sites is much greater than the percentage of injured sites. Results indicate a declining trend in foliar injury especially after 2002 when peak ozone concentrations declined across the entire region.

“…In the case of the ozone bioindicator, the risk of forest tree injury is based on interpolated information collected at ozone biomonitoring sites (Coulston et al 2003;Smith et al 2007). Examples of regional and national risk assessments can be found in Coulston et al (2004), Ambrose and Conkling (2007), Campbell et al (2007), and Rose and Coulston (2009). The goal of risk assessments is to identify candidate areas for subsequent investigation during the evaluation monitoring phase of the FHM program.…”

For two decades, the US Department of Agriculture, Forest Service, has been charged with implementing a nationwide field-based forest health monitoring effort. Given its extensive nature, the monitoring program has been gradually implemented across forest health indicators and inventoried states. Currently, the Forest Service's Forest Inventory and Analysis program has initiated forest health inventories in all states, and most forest health indicators are being documented in terms of sampling protocols, data management structures, and estimation procedures. Field data from most sample years and indicators are available on-line with numerous analytical examples published both internally and externally. This investment in national forest health monitoring has begun to yield dividends by allowing evaluation of state/regional forest health issues (e.g., pollution and invasive pests) and contributing substantially to national/international reporting efforts (e.g., National Report on Sustainability and US EPA Annual Greenhouse Gas Estimates). With the emerging threat of climate change, full national implementation and remeasurement of a forest health inventory should allow for more robust assessment of forest communities that are undergoing unprecedented changes, aiding future land management and policy decisions.
