Washington AI Tool Maps Hidden Wetlands
SkimNews Take
Shrinking federal oversight of wetlands is shifting the burden of identifying and preserving these ecosystems onto state-level technological solutions and their associated resource demands.

- EPA clarified in November 2025 that wetlands with only seasonal surface water or that touch year‑round water bodies lose federal protections, affecting tens of millions of acres.
- Amy Yahnke said Washington stakeholders need a better way to identify forested wetlands before they lose federal protections.
- Meghan Halabisky warned that climate‑driven wetter winters and hotter, drier summers in eastern Washington will cause wetlands to dry earlier, reducing their visible connection to water bodies.
- Dan Miller co‑developed the AI‑based Wetland Intrinsic Potential tool that models landscape features to assign a probability that a location is a wetland.
- Washington Department of Ecology uses the WIP tool’s digital elevation model data to calculate slope and concavity, uncovering hidden wetlands in hills and mountains.
- Jacob Taylor reported that the WIP tool has been applied in Spokane County since June 2025 to map wetlands at finer resolution, assisting farmers in identifying potential wetland areas on their land.
Why it matters: Farmers, developers, and conservation agencies gain a data‑rich method to pinpoint cryptic wetlands, allowing them to meet the narrowed Waters of the United States rules and protect flood‑control, carbon‑storage, and biodiversity functions that would otherwise be lost under the EPA’s 2025 definition.
