tentative observations
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
