  17. Tentative Observations • Rootarchitecture is tree species dependent • Oaks tend to keep their root mass within the canopy perimeter and have robust tap roots • Cottonwood roots travel far afield & aggressively search for water and nutrients • Seepage through old stump roots may be slowed • Rodent holes may play a strong role in levee seepage

  18. 2011 Upcoming Activities • WindthrowStudy: Season 2 @ Natomas, Nelson Bend, Feather River, Bear River • Tree Root Piping, Seepage, & Slope Stability Study: Season 2 • Burrowing Mammals Study: Season 2 • Levee Failure Forensics Study
