Brush mouse reports form a broken chain between the Gila and Lincoln national forests. That gap makes sense in New Mexico, where wooded slopes sit like islands above broad stretches of desert and grassland.
The record rises in May and June, then shows another distinct lift in October. Those separated peaks are useful clues about reporting effort, not proof of two population surges. A small night-active mouse can go unreported even where the habitat fits.
