Wetland Research Initiative (WRI)

Wetland Studies and Solutions, Inc. (WSSI) established the Wetland Research Initiative (WRI) in 2007 in collaboration with the U.S. Army Corps of Engineers, the Virginia Department of Environmental Quality, the U.S. Fish and Wildlife Service, and one of WSSI’s mitigation bank financial partners, The Peterson Companies (through their Peterson Family Foundation [PFF]). The goal was to create a wetland mitigation research funding mechanism from revenues generated by a portion of credit sales in three mitigation banks (Bull Run, Cedar Run, and North Fork).  

The mission of the WRI, now managed through the Resource Protection Group, Inc. (RPG) (a non-profit 501(c)3) and founded by Mike Rolband, is to fund applied research that makes a real and measurable difference in wetland creation, restoration, and enhancement activities in the Virginia Piedmont.  To date, the WRI has awarded over $3.3M in grants.  The existing and completed research projects funded by this program have focused on the overall effectiveness of compensatory mitigation efforts and specifically how design and construction practices should be modified to improve the performance, in terms of functions and values, of compensatory mitigation.

2016 Wetland Mitigation Research Symposium

This April 14, 2016 WRI symposium in WSSI's Gainesville headquarters, sponsored by WSSI and RPG, brought scientists, engineers, and government staff together to further explore compensatory wetland mitigation design, particularly water budget modeling.

Presentation Slides: 


2015 Wetland Mitigation Research Symposium

WSSI and PFF hosted a second symposium in conjunction with the Virginia Association of Wetland Professionals' Annual Fall meeting. Presentations focused on WetBud, the wetland water budgeting program developed by an interdisipclinary team of scientists from Virginia Tech, the University of Kentucky, and Old Dominion University, and funded by WRI. In addition, researchers from the Virginia Institute of Marine Science and Christopher Newport University shared results from studies focused on improving wetland reforestation practices.

2013 Wetland Mitigation Research Symposium

On March 13, 2013, WSSI hosted the first WSSI/PFF Mitigation Banking Research Symposium, an at-capacity event where researchers shared results from studies funded by the WRI and discussed mitigation design and permitting challenges facing both the government and private sectors. Attendees included leadership from a multitude of regulatory and state agencies, including the U.S. Environmental Protection Agency; the U.S. Army Corps of Engineers; Virginia's Departments of Environmental Quality, Game and Inland Fisheries, Conservation & Recreation, and Transportation; the District Department of the Environment; and the Maryland Department of the Environment.
Professors and students from Christopher Newport University, Duke University, George Mason University, Old Dominion University, Penn State, Virginia Tech, and the Virginia Institute of Marine Sciences, all of whom received WRI grants, made presentations throughout the day. The EPA and the USACE Engineering Development Center made presentations about new wetland assessment tools and federal support to compensatory mitigation.
