- Conservation Status and Ecology of the Monarch Butterfly . . . - NatureServe
In this report, we briefly summarize the monarch’s North American distribution, life history, pop-ulation, current conservation status, and potential causes of decline In addition, we include a set of breeding and overwintering habitat management recommendations

Listed below are definitions for interpreting NatureServe’s global (range-wide) conservation status ranks Global conservation status ranks are assigned by NatureServe scientists or by a designated lead office in the NatureServe Network

- Conservation Status Assessment - NatureServe
Using a 5-point scale from critically imperiled (1) to secure (5), we evaluate data and published studies to assign conservation status ranks at three geographic scales: global, national, and subnational We call these Global, National, and Subnational Ranks (or “G-Ranks,” N-Ranks” and “S-Ranks”)
- Statuses | NatureServe Explorer
For ecosystems, ranks are currently available for many NatureServe Terrestrial Ecological Systems and for IVC groups and associations in the United States; ranks for IVC alliances are being developed
