Data Release for Assessing the Impact of Changing Water Resources on Migratory Bird Health and Management in the Central Flyway of the United States Data Release for Assessing the Impact of Changing Water Resources on Migratory Bird Health and Management in the Central Flyway of the United States
There is a growing movement within natural resource management to view wildlife health as a cumulative outcome of many different factors, rather than simply the absence of disease. This inclusive understanding of health opens the door to management options that are more creative than traditional techniques to prevent or mitigate pathogens. The public health field uses a determinants of...

Risk assessments of animal species, plant species, and disease in the United States available online between 1990 and 2023 Risk assessments of animal species, plant species, and disease in the United States available online between 1990 and 2023
Risk assessments describe the risk of a species’ invasion in a location, and many risk assessments have been produced by different institutions for various reasons. However, information is sporadically located online, increasing the difficulty of developing comprehensive lists of species with risk assessments or comparing assessment results across species in locations of interest...
