Dr. Morrison has over 27 years of experience evaluating the relationship between anthropogenic activities and health effects to natural resources and humans. Dr. Morrison specializes in natural resource damage assessment (NRDA), environmental causal analysis, risk evaluations, net environmental benefit analysis, and assessments of water quality conditions.
Integrating her expertise in ecology, biology, chemistry, causal analysis, and data analysis, Dr. Morrison supports the development and execution of corporate sustainability, environmental, social, and governance (ESG) objectives.
Dr. Morrison has provided scientific consultation regarding the design of field studies for NRDA, and she has worked closely with legal counsel during scientific assessments and settlement negotiations with state and federal parties. Dr. Morrison has performed detailed technical assessments of risk and injuries to natural resources, including vegetation, benthic infauna, fishes, shellfishes, corals, birds, and wildlife. She has also developed site-specific sediment toxicity thresholds based on the empirical relationships of chemical concentrations to biological effects and evaluated the impacts of climate change events to ecological populations. Dr. Morrison has provided scientific consultation on carbon sequestration in natural working lands and on life cycle assessment inputs for industrial processes. She has offered expert testimony concerning potential injury to natural resources, environmental impacts associated with development projects, net environmental benefits of remediation alternatives, and biofouling of marine assets.
Projects Dr. Morrison has been involved with have concerned oil spills, sewage releases, heavy metal contamination, polychlorinated biphenyls, coal ash, phosphate mining, harmful algal blooms, water rights, carbon footprints, and various industrial and municipal facilities that have generated complex releases to the environment. Dr. Morrison uses her broad knowledge of biology, ecology, toxicology, chemistry, statistics, and human health to assess risk and injury, evaluate sustainability, weigh net environmental benefits, analyze causation, evaluate climate impacts, and support decision making.
Ann's recent insights
Dr. Morrison has been involved in numerous complex projects relating to environmental contamination, causation, and potential risk to humans and biological resources in the affected environment.
