Stabilization of European coastal sand dunes over the last 60 years has led to the loss of habitat for invertebrate and plant species that specialize on mobile sand dune environments. Recent management efforts in the United Kingdom have focused on remobilizing, or rejuvenating, portions of these systems to recover these rapidly disappearing habitats. These rejuvenation efforts include mechanically stripping large patches of vegetation from stabilized dune surfaces and excavating stabilized dune slacks (interdunal wetlands) to the water table. It is unknown, however, how these rejuvenation sites should be chosen to best encourage their colonization by active dune and primary slack specialists. In this project, we will develop mathematical models of the growth and dispersal of populations of dune specialists in rejuvenated dune systems. We will also conduct field experiments to measure individual movement patterns and population densities as the populations disperse through the dunes after the interventions. These data will be used to parameterize and validate the mathematical models, which will be used to explore questions relevant to dune management in the United Kingdom. Through studying these dune systems, we hope to develop techniques and insights that will also help us to understand the spatial ecology of Great Lakes sand dunes, which may be undergoing similar stabilization. Starting in 2017, students and faculty from Hope College and Liverpool Hope University will work as interdisciplinary teams to conduct fieldwork in the United Kingdom, to analyze data, and to develop spatial ecological models.
