  • There was a lot of controversy surrounding the new colony of beavers. The airport claims the beavers are posing a safety threat to air traffic, while the school sees the beavers as an educational opportunity for the children. These conflicting opinions produced the need for an unbiased assessment of the impact of the beavers.

  • 10mg/l is max level
  • Instrumentation max is 2.75
  • Different methods
  • No conclusive evidence
  • Popular belief is that beaver dams filter out sediment, however, the turbidity is higher downstream of the
  • Beavers arrive 2010
  • Point out that wetlands that the beavers created are considered hazardous, not the beavers themselves.
  • Flow chart
  • Our sponsor asked us to create a video that would counteract the negative sentiments of local land owners and display the positive impacts of beavers
  • Transition to land assessment
  • All of the data collection from our project has laid the foundation for other schools to begin collecting their own data all along the riverThis information can then be shared on the information platform created by the water group Making information available to other educators as well as city officialsOutdoor education programs can build leaders for the future who understand the needs of their community
  • Assesses environmental impact and can conclude that wetlands created by beaver dams recharge aquifers. No evidence to show that flooding or wetlands have a direct consequence on airport safety.
