Evaluating the Cumulative Impact of Multiple Stressors on Cetaceans

This Monitoring and Adaptive Management (MAM) activity is developing models of the effects of multiple stressors on marine mammal stocks that were injured during the Deepwater Horizon oil spill. The project will develop a framework for modeling population dynamics, physological effects of stressors, and the effect of the physiological changes on reproduction and survival. The project will focus on sperm whales and oceanic dolphins, using the framework to develop models for these two groups.

Juvenile Gulf Sturgeon - Gulf-wide Population Dynamics and Habitat Use

This Monitoring and Adaptive Management (MAM) activity will examine juvenile Gulf sturgeon habitat use and preference in estuaries in the northern Gulf of America to: (1) better understand baseline status and conditions, (2) identify and prioritize habitats most in need of restoration, and (3) provide a framework for monitoring the results of restoration in an adaptive management context.

Informing Gulf Sturgeon Population Status and Trends as a Baseline to Evaluate Restoration

This Monitoring and Adaptive Management (MAM) activity entailed two major tasks that required desktop analyses and training with no field work, (1) Conducting a Gulf sturgeon populations assessment and (2) Developing a standardized data collection and storage program for Gulf sturgeon data. Task 1 included reviewing and compiling existing Gulf sturgeon capture-recapture information into a database, building age-structured-mark-recapture models to estimate Gulf sturgeon abundance, and developing an individual-based population viability analysis (PVA) model.

Restoration of Black Terns in North and South Dakota

This project will restore black terns by protecting approximately 2,000 wetland acres and 1,000 grassland acres on private lands in the Prairie Pothole Region of eastern North and South Dakota with conservation easements established with willing landowners. Previous surveys of occupied wetlands support the Trustees’ estimate that >1,000 individual black terns will be present on project wetlands when habitat conditions are optimum.

Characterizing Gulf Sturgeon Spawning Habitat, Habitat Use and Origins of Juvenile Sturgeon in the Pearl and Pascagoula River Systems

This project will provide data for targeted restoration activities of Gulf sturgeon in the Pearl and Pascagoula River systems and is designed to support the selection of priority restoration projects that target spawning habitat and/or spawning habitat enhancement. Data collected will include the location and extent of essential spawning habitat, patterns of accessibility and use of this habitat by adult Gulf sturgeon, and origins of juvenile sturgeon.

Open Ocean Monitoring and Adaptive Management Planning

This project will conduct comprehensive planning to develop and implement a monitoring and adaptive management (MAM) framework and plan the effective use of the MAM allocation for the Open Ocean Restoration Area. It will evaluate the outcomes of the Open Ocean restoration effort across the portfolio of Open Ocean projects, identify and fill data gaps that affect the Open Ocean TIG’s ability to meet and/or evaluate progress toward restoration goals for Open Ocean resources, and identify the benefits of restoration activities to Open Ocean resources and the Gulf of America ecosystem.
