Conclusion  •  Street  trees  are  common-­‐pool  resources  (CPR’s):    –  Subtractable:  if  I  cut  down  a  street  tree,  you  can  no  longer  benefit  from  it  

– Difficult  to  exclude  people  from  (public  property)  •  CPRs  are  vulnerable  unless  well  managed  •  City  monitoring  of  public  trees  is  cri?cal  for  both  public  and  private  trees  in  Bloomington  –  EXAMPLE:  Pest  management  benefits  ALL  trees  in  urban  forest  

•  We  recommend  establishing  an  annual  budget  line  for  monitoring  (inventorying)  trees
