Ecological Assessments and Habitat Restoration

Investigation and Assessments

The Johnson Company’s experienced engineers and environmental scientists design and conduct field investigations and ecological assessments to determine existing, as well as potential, impacts to natural resources.

Our investigation techniques include:

• sediment sampling
• stream monitoring
• aquatic plant and benthic invertebrate surveys
• fish and aquatic vertebrate collection
• toxicity testing
• tissue analysis, and
• quantitative and qualitative natural community analyses.
  
  

We use the results to develop environmental impact statements, support natural resource damage assessments, provide the basis for wetland delineation and functional analyses for state and Federal wetlands permits, perform ecological environmental risk assessments, and to apply for environmental permits.

Mitigation and Restoration

We design wetland and habitat restoration projects and develop mitigation plans to restore natural communities affected by contamination or economic development. As part of every project we identify sensitive natural communities at the conceptual and planning stage so that impacts can be minimized and the project completed on time and on budget.  Our environmental scientists combine with our engineers to develop bid documents and oversee construction of restoration projects.

Our services can include long-term monitoring and regulatory reporting of the restoration.
