Greg Sproull



Greg Sproull is a project manager and biologist with WRA, Inc. He has more than 10 years of scientific experience in academia and in the private sector in the United States and abroad.  Prior to his time at WRA, Greg was a regulatory permitting specialist, wetland scientist, and botanist for an environmental consulting firm in the San Francisco Bay Area, where he contributed to more than 50 environmental services projects.  As a William J. Fulbright research scholar in Poland, he assessed fine-scale mortality dynamics in subalpine spruce communities and created an analytical modeling system to predict future mortality drivers and patterns.  Greg’s research effectively changed Poland’s Tatra National Park’s 2015 20-year forest management plan to incorporate more ecologically sustainable management techniques and strategies.  Greg’s graduate research involved floristic composition, diversity, and distribution surveys in plant communities along an elevation gradient, which elucidated long-term drivers of herbaceous change in the Colorado Front Range.  Greg has also instructed biology courses, worked as a senior scientific editor, and coordinated a USDA-funded scientific laboratory.

At WRA, Greg regularly interfaces with clients and government agencies to provide sound environmental solutions.  Greg frequently coordinates and performs wetland delineations; manages floristic surveys, vegetation mapping, and habitat assessments; and authors and reviews complex regulatory permit applications and biological resource assessments for CEQA documents and client reports.  He integrates his critical thinking abilities, scientific expertise, and well-rounded interpersonal skills to address clients’ environmental challenges with an effective, sedulous, and objective approach.
