ABSTRACT
RSA remains the only direct health status assessment method in ecological risk assessment (ERA). This vetted and patented method is predicated upon thinking that seems to evade the mind-reach of ERA practitioners. This study, perhaps the most straightforward of those in this compendium, invites inquisitive individuals to immerse themselves in RSA application, seeking out opportunities to expand the database of reported outcomes. With only two criteria to be satisfied for method application, opportunities to partake in the work ahead are really limitless. Additional applications of the method will necessarily secure information of a broader range of sites, and importantly will expand the list of rodents species reviewed. Recalcitrant ERA practitioners can come to shed their bias that takes the form of an insistence that ecological impacts abound at sites, when a wealth of information spanning different types of sites, and reporting on multiple species, indicates otherwise.
