Hydro-Carving Approach a Success at Balm-Boyette Stallion Creek Restoration This restoration project seemed fairly straightforward at first blush: grade the pits, plant native species, and restore the freshwater wetland and upland communities back to the way they were before the area was mined. Then Tom reviewed a historic aerial of the site. “There was a creek there that was breached by the mining activities, which resulted in the creek being cut off from the natural flow patterns in the region,” Tom Ries explains. “As soon as I saw that, I thought, ‘well, we have to restore that creek.’” Read More »

Navigable Waters Protection Rule (NWPR) On January 23, 2020 the EPA and Department of the Army finalized the “Navigable Waters Protection Rule” (NWPR) to define “waters of the United States” (WOTUS). The new rule finalizes a two-step process to replace the 2015 Clean Water Rule, which also re-defined WOTUS. ESA’s team of environmental permitting specialists are reviewing the NWPR to understand how it may affect our clients and their projects, including the potential jurisdictional status of various aquatic features.

Research Shows Nutrient Diet Improves Water Quality, Fishery Habitat Across the globe, coastal zone management efforts have concluded that restoring fish populations often requires acting on land-based human activities. With a few notable exceptions, most commercially and recreationally important species of fish, crabs, and shrimp spend at least a portion of their lives in estuarine locations, where waters from the open ocean mix with runoff from land.

Environmental DNA in a Regulatory and Operational Landscape Environmental DNA (eDNA) is DNA collected from the environment—water, soil, and air—rather than directly from an organism. All organisms add DNA to their environment by excreting waste, shedding, decomposing, etc. Since short stretches of DNA contain information that identifies species and populations, genetic testing of environmental samples can reveal the presence of animals and plants nearby.
