Assessing Pesticide Assessing Pesticide Exposure to Endangered Exposure to Endangered Species in North DakotaSpecies in North Dakota
Jessica JohnsonNorth Dakota Department of Agriculture
Stakeholders Feedback on T/E Stakeholders Feedback on T/E IssuesIssues
� Uncertainty with national pesticide T/E issues� Desire to have input on any mitigation
measures to ensure they are reasonable� Want to utilize non-regulatory approaches
when they are shown to be effective � Want to ensure that EPA is operating with
most accurate data available
North Dakota’s Endangered North Dakota’s Endangered Species PlanSpecies Plan
North Dakota’s Goals for North Dakota’s Goals for Endangered Species Endangered Species Protection Protection
PlanPlan• Protect Endangered Species without causing
an unreasonable burden to agriculture producers
• To supply EPA with state specific information to use in risk assessments
• To provide a platform for stakeholders to offer input and recommendations
• To help plan and implement mitigation and management plans, including Endangered Species Protection Bulletin (Bulletins)
Data inputData input� Many different sources have data� State agency data often ignored or not
asked for during risk assessments� There are no procedures currently in place
for states to offer data to be used for risk assessments or bulletin development
State Information useful for a State Information useful for a Registration ReviewRegistration Review
� State water quality monitoring data� Pesticide use data� Cropping information� Endangered species locations� Local soil types
State Information useful for State Information useful for Bulletin DevelopmentBulletin Development
� Technological, social and economic feasibility of restrictions� State can work with growers to gain buy
in and compliance with bulletins or other restrictions� Review bulletins and associated maps for
accuracy

� Richland and Ransom counties are listed for western prairie fringed orchids
� Large areas of both counties do not have orchids
The FutureThe FuturePossible state program- map based with
voluntary recommendations, work with local FWS
SummarySummary� States have information that could be
useful during decision making� Bulletins can have a high economic
impact, agencies should examine all data available
