BLM OR Fish Non Native Arc Hub: Non-Native Fish Presence for Stream Buffer Management

Oregon streams contain data on the presence of non-native fish species, which can affect protection buffer widths in land management plans. The feature class originates from the Hydro Update Project, with determinations based on actual observations or modeled presence by trained specialists. The Department of the Interior published this dataset, which was last updated on April 14, 2026.

Use Cases

• Determine protection buffer widths for land management plans based on non-native fish presence.
• Model habitat suitability for non-native species based on observed or modeled fish presence data.
• Verify species distribution for conservation planning using observations from trained specialists.

Strengths

• Data is derived from the Hydro Update Project, suggesting a structured collection effort.
• Determinations were made by trained specialists like fish biologists, indicating expert verification.
• Last updated on 2026-04-14, suggesting recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
