SOP publication lists

The publication index lists below are divided by categories relating to the types of monitoring or scientific analyses performed by our scientist teams. Since all science staff working in the field use SOP EAP070, procedures to minimize the spread of invasive species, it is not categorized separately, but as "general environmental assessment." All others are listed by the work performed by each team.
