Who we are
An Oregon consulting firm for wetlands, waters, and habitat
Zion Natural Resources Consulting has worked on wetland and natural resource projects across Oregon since 2002. The firm is led by Eric Henning, who handles each project from the first site visit through agency approval.
We figure out where wetlands and other waters are on a property, what rules apply, and what it takes to move a project forward. Then we do the field work, mapping, reports, and permit applications that Oregon DSL, the U.S. Army Corps of Engineers, and local governments need to see.

A straightforward path through the process
- 1
Initial review
We look at your site, mapping, and plans, and tell you which regulations are likely to apply.
- 2
Field work
On-site investigation of soils, hydrology, and vegetation, surveyed with sub-meter GPS.
- 3
Reports and applications
Delineation reports, permit applications, and plans prepared for agency review.
- 4
Agency follow-through
We answer agency questions, coordinate revisions, and support compliance after approval.
GIS surveying and mapping
Sub-meter field data, mapped in ArcGIS Pro
Wetland boundaries, sample plots, and site features are surveyed with sub-meter GPS, then mapped and analyzed in ArcGIS Pro for accurate acreages, impact calculations, and figures that hold up in agency review.
About our GIS work
Regulatory experience
Working alongside the agencies that review your project
Wetland work in Oregon usually involves more than one reviewer. We prepare work to the standards each one expects and coordinate between them.

Where we work
Oregon and its diverse landscapes
Oregon's wetlands and waterways are as varied as the state itself: Willamette Valley wet prairies and farm fields, forested streams in the Coast Range and Cascade foothills, tidal estuaries, and high-desert wet meadows. We bring the same careful field work to each of them.
