TN&A offers a variety of services related to the identification, protection, and restoration of our natural environment. Our multidisciplinary natural resources team includes accomplished ecologists, wildlife biologists, hydrogeologists, GIS specialists, and engineers. These hands-on professionals design and oversee wetland restoration sites, restore stream banks and in-stream habitat, and perform a variety of habitat assessments and floral/faunal surveys. We have extensive experience in formulating long-term resource management plans, emphasizing establishment of native flora and fauna.
TN&A designed a tributary that was being relocated due to a roadway improvement project to expand US Highway 45. TN&A conducted a pre-design field investigation to assess the baseline biological, physical, hydrologic, and chemical conditions of the tributary. We used a regional regression hydrological model, in conjunction with digital terrain data, to calculate flood magnitude and frequency for the design corridor. The final restoration design utilized several engineering and bioengineering techniques to effectively stabilize the newly constructed stream banks. TN&A also provided construction management during the stream channel construction and change over.
TN&A conducted a preliminary assessment/site inspection of former coal mining sites at the Wayne National Forest, Ohio. TN&A assessed the current status of water quality, as well as species diversity and habitat present within the study area. A biological survey of each area was conducted in representative areas of the watersheds. Investigative field work concentrated on areas that could be affected by future reclamation work in the vicinity of mine subsidences and within a 200-yard corridor centered on each acid mine drainage-impacted stream.
