11 12 final invasives and health smj_july24_english

  1. 1. Indicator 11: Terrestrial Invasive Species and Indicator 12: Forest Health Watershed Condition Framework Application Workshop Polyana, Ukraine July 23-27, 2018 Sheela Johnson Natural Resource Specialist, USDA Forest Service
  2. 2. Indicator Attribute Good (1) Functioning Properly Fair (2) Functioning at Risk Poor (3) Impaired Function 11. Terrestrial Invasive Species 11.1 Extent and rate of spread Few (less than 10 percent) or no populations of terrestrial invasive species infest the watershed. Those that occur are small in extent and scattered in nature. The rate of spread and/ or potential for impact on watershed resources is minimal or unlikely. Populations of terrestrial invasive species are established within (10 to 25 percent) the watershed and/or the rate of spread and/or potential for impact on soil, vegetation, or other water resources is moderate. Treatments must be ongoing. Populations of terrestrial invasive species infest significant portions (more than 25 percent) of the watershed, may be expanding their range, and widespread impacts to soil, native vegetation, or other water resources have been documented. Treatments need to be ongoing.
  3. 3. Indicator 11: Terrestrial Invasive Species 0% 10% 25% 100% % watershed with invasive species
  4. 4. Terrestrial Invasive Species
  5. 5. Invasive Species Survey and Treatment: On the Ground Work Identified infestation: yellow Treatment: orange triangle Pathways for spread: • Roads • Trails • Waterways
  6. 6. Invasive Species Survey and Treatment
  7. 7. Indicator Attribute Good (1) Functioning Properly Fair (2) Functioning at Risk Poor (3) Impaired Function 12. Forest Health 12.1 Insects and disease Less than 20 percent of the forested land in the watershed is at imminent risk of abnormally high levels of tree mortality (25% in a stand) because of insects and disease. Between 20 and 40 percent of the forested land in the watershed is at imminent risk of abnormally high levels of tree mortality (25% in a stand) because of insects and disease. More than 40 percent of the forested land in the watershed is at imminent risk of abnormally high levels of tree mortality (25% in a stand) because of insects and disease. 12.2 Ozone Ozone causes a decrease in biomass growth in fewer than 20 percent of the years evaluated. Ozone causes a decrease in biomass growth in 20 to 40 percent of the years evaluated. Ozone causes a decrease in biomass growth in more than 40 percent of the years evaluated, and/or the watershed area exceeds Air Quality Standards for ground-level ozone.
  8. 8. 12.1 Insect and Disease 0% 20% 40% 100% % watershed at risk of high mortality
  9. 9. Insect and Disease: Damage Legend Insect and Disease Survey Damage DMG_TYPE Mortality Defoliation Other Data from U.S. Forest Service aerial detection surveys https://foresthealth.fs.usda.gov/portal/Flex/IDS
  10. 10. Insect and Disease: Risk Predicted basal area loss, 2013 - 2027 Predicted areas with over 25% basal area loss, 2013-2027 Divide high risk area by watershed area Source: https://foresthealth.fs.usda.gov/nidrm/
  11. 11. 12.2 Ozone 0% 10% 25% 100% % years ozone causes decreased growth
  12. 12. Ozone Damage • Evaluate ozone levels (stressor) • Identify sensitive tree species • Identify species presence in watershed • Evaluate ozone risk
  13. 13. Ozone Damage: U.S. Example Prunus serotina estimated biomass loss due to ozone https://www.nps.gov/subjects/air/nature-trees.htm
  14. 14. Ozone Damage: possible data sources Source: EMEP-MSC-W http://emep.int/publ/reports/2015 /Country_Reports/report_UA.pdf Critical level for forest impacts: 5000 ppb-h % Change in ozone indicators in Ukraine from year 2000
  15. 15. Next Steps: Collaboration and Citizen Science Information is shared among organizations through the Midwest Invasive Species Information Network (MISIN) Treatment Tracking database
  16. 16. Next Steps: Collaboration and Citizen Science European Alien Species Information Network (EASIN) has mapping services through data partners, and includes a citizen science component. http://alien.jrc.ec.europa.eu/SpeciesMapper
