What we do

Research, analysis, and the plan that follows

Watershed councils, agencies, and community groups bring a question. We study it, rank the options, and write the plan.

01

Research

Habitat, sediment, and limiting-factor assessments for watershed councils and agencies. Fieldwork, sampling, and analysis follow the agreed scope when needed.

  • Habitat assessments
  • Sediment and shade
  • Limiting factors
02

Analysis

Ranks restoration reaches using habitat data, surveys, GIS, and existing reports, so the work starts where it matters most.

  • Restoration priority
  • Fish passage
  • Rearing habitat

Supporting method: GIS and mapping. Drinking-water and housing overlays, passage, and habitat maps that explain the resource visually.

03

Planning

The action plan is the written packet after the research: the plan a council can fund, with restoration priorities for the work plan.

  • Action plans
  • Restoration work plans
  • Scope and timeline
