  1. Restoring Balance to the Great Bay Ecosystem SWA Symposium, May 11, 2011 Richard Langan, UNH

  2. Lay of the Land.. and Water • Great Bay Estuary & Watershed • Multiple stressors & cumulative effects • Population growth, development • Loss of habitats and ecosystem services • It’s about quality of life too…. • Business as usual won’t cut it

  3. An alternative approach? • Ecosystem problems require ecosystem solutions • Science matters, but so do a lot of other things • We need to all share the pain.. and eventual gain • Process is important • We don’t need to know everything to do something • We do have some tools – let’s start using them

  4. Population in GBE Watershed towns 52% increase in 28 years

  5. Top down options: bioextraction

  6. Microalgal Biomass Production?

  7. Possible Plant Locations Portsmouth, NH Dover, NH Newington + PSNH Exeter, NH Durham, NH Collectively contribute 330 tons TN

  8. Recommendation • Establish an inclusive forum • Collectively define problems, solutions and goals • Consider non-technical barriers • Be creative • Measure progress • Be flexible • Cautions • Process takes time, $, skills and commitment • Restoration takes longer • There will always be gaps • $$ are limited, use them wisely
