Restoration and Reclamation
Once species or their habitat have declined, restoration and reclamation is needed. One important component of restoration and reclamation is developing habitat offsets. Many countries have adopted habitat offsetting policies (e.g., Canada, United States, Europe, Australia, New Zealand, and United Kingdom), where the ideal goal is ecological equivalency, such that offsets are done in a manner which replaces habitats “like-for-like” in areas in close proximity to where those habitats were displaced. When ecological equivalency cannot be achieved with habitat offsets, such as when the extent, duration and intensity of the impacts are sufficiently broad in spatio-temporal scale (e.g. surface mining, Sun et al. 2017), offsetting currencies and flexibility may be needed. Research topics include: assessing the efficacy of fish stocking for restoration, developing methods to for offsetting fisheries productivity, advancing expertise and methodologies in hydroacoustics.
