IPM-Centric Ordinances

Once IPM is adopted as official city policy, it provides a stronger legal foundation for taking actions that some might believe unnecessary. Equally important, it provides a starting point for public engagement long before any pest invasion.

Cities that codify IPM

Even IPM can become polarizing

Under IPM, some diseases and infestations will need to be treated with chemicals. That option creates a difficult challenge for local policymakers. Even after all other methods have been ruled out, the politics of chemical use may derail fruitful response.

In this black and white photo from 1917, two men are applying pesticides to one tree in an orchard. One man is holding and pumping a pumping the chemicals, while the other man is holding a long sprayer that is connected to the pump via short hose. The man holding the long sprayer is holding the sprayer up to touch the leaves near the top of one tree.
As early as 1917, use of chemicals to keep trees healthy was controversial.

Still a battleground

Some of the most harmful forest pests have spread so rapidly and so far that the only practical response may be to either remove all infected trees, or resort to chemical treatment — if it’s available and effective.

Needless to say, these decisions spark strong feelings. Officials must cope with diverse and intense debate.

These communities confronted this challenge head-on.
