Many cavity-nesting vertebrates rely on tree cavities for nesting, and these cavities are often a limiting resource. The availability of tree cavities depends on rates of formation, persistence, and degradation or change in characteristics (e.g., entrance area, chamber volume, level of decay). Understanding how cavity characteristics change over time is key to understanding the value of cavities for wildlife as they age. We measured physical characteristics of 960 tree cavities for up to...[Show more]
