1. 2008/2009 Forest Watch Data Book Review & Discussion: Ozone summary for 2008, Spectral & Biometric Data Analysis

2. Forest Watch offers students and teachers authentic opportunities in science by participating in on-going research to assess the health of forests in New England. several ecological and biophysical measurements in white pine stands, looking for signs of ground-level ozone damage and other forest health concerns.

3. Eastern White Pine Pinus strobus Selected Because: It is a Bioindicator of Groundlevel Ozone (SMOG) Exposure Common in New England Retains foliage year-round, can be studied throughout the school year Often occurs outside the classroom (a local fieldtrip)

8. 1-hour 120ppb (parts per billion): the average of the 4 highest values must be < 120ppb over any 1 hour period each day. 8-Hour (1997) 80ppb (parts per billion): the average of the 4 highest values must be  80 ppb over any 8 hour period each day. 8-Hour (2008) 75ppb (parts per billion): the average of the 4 highest values must be < 75 ppb over any 8 hour period each day. NATIONAL AMBIENT AIR QUALITY STANDARDS NAAQS

9. 1971: EPA established a 1-hour ozone standard of 80 ppb. 1979: EPA revised the 1-hour standard to 120 ppb. 1997: 1-hr 120ppb revised to 8-hr 80ppb 2003: States and Tribes Submitted to the EPA their designations for non-attainment. 2004: Official non-attainment designations based on data from 2000-2002. (avg. annual 4 th highest max daily 8-hr values from 55+ stations) 2005: 8-hr 80ppb NAAQS made official. 2007:State Tribal and Local Governments submit State Implementation Plans (SIP’s). detailing how they will meet attainment by deadlines determined by their non-attainment status. 89 of 126 areas nationally listed in non-attainment met standard between 2004 and 2006 (13% ozone decline 02-06!) 2008: March 12 th 2008, new 8-hr 75ppb NAAQS made official 2009: States and Tribes Submitted to the EPA their designations for non-attainment. 2010: March, official designations based on 2007-2009 monitor data, followed by revised SIP’s 2013-30: Attainment dates depending on severity of problem OZONE POLICY IN TRANSITION:

20. In 2008, high REIP values corresponded to low ozone values as they have in most years since Forest Watch began. 2004 through 2007 are our highest REIP values. REIP is rising over time, Our white pines are getting healthier!
