Overview of Monitoring Activities

Monitoring involves several different activities. Together, these activities help us to track monarch populations, understand monarch use of available habitat, and investigate some factors, such as weather and parasitism, which affect monarch populations.

You can choose to do as many or as few MLMP activities as you'd like, but in particular, we encourage Description of Monitoring Site, Milkweed Density, and Activity #1 Monarch Density. The more activities you complete, the more we learn, but please only do what you have the time and energy to complete.

Print the datasheets (see below), bring them with you to your monitoring site to fill out, then login to enter your data online. Please send us hard copies of your data at the end of the summer so that we can check our database for accuracy.
