You can help improve the USA-NPN's Pheno Forecasts that predict activity of harmful pest species! Pest Patrol includes 13 species of pests that damage forest and agricultural trees. By signing up for the campaign, you will receive notifications that tell you when to look for life cycle stages such as active caterpillars and active adults in your area.

Monarchs, one of our most iconic butterflies, rely on a wide variety of nectar sources spread over a large part of the United States. Changes to these food sources, through habitat loss, pesticide use, and/or climate change, can be costly to monarch populations, as well as to the many other pollinators that rely on these same species for their dietary needs. Help us better understand the phenology of important nectar sources for monarchs and other pollinators.

Your observations of lilac life cycle events can enhance the decades of lilac phenology records that have been collected across the U.S. Plant and observe a cloned lilac or report observations of a common lilac already established in your yard.

Observations of cloned and native flowering dogwood are valued for the data gap they fill, especially in the southeastern U.S.

Join us in tracking the Green Wave -- the flush of green that accompanies leaf-out -- in maples, oaks, and poplars over the course of the spring season, as well as the spread of seasonal color across the country in the autumn. 

Quercus Quest seeks to better understand the complexities of oaks through phenology. Join us in tracking leafing and flowering of oaks across the eastern US. 

The redbud is an icon of early spring, but little is known about its phenology. This campaign seeks to learn about when eastern and western redbuds flower and fruit across their range and whether the timing has advanced in recent years. 

Monarchs overwinter in Arizona, but much is unknown about their winter breeding behavior and use of milkweed. Desert Refuge: Monarchs and Milkweeds in Arizona seeks to collect information about the timing of monarch and milkweed seasonal activity across the state. 

Do you suffer from allergies? Help scientists better understand the connection between open flowers and pollen concentrations. Your data will lead to improved allergy forecasts! This national campaign includes 15 genera of plants including birches, junipers, ragweed, and more! 

Mayflies are an important food source for a variety of animals and a good indicator of water quality. Help the US Fish & Wildlife Service track the emergence of mayflies along the Upper Mississippi River and its tributaries this summer! 

If you live in Southeastern Arizona, you can help the US Fish & Wildlife Service document flowering of agave and saguaro cactus during the spring and summer flowering periods, an effort called Flowers for Bats. This information will be used by the FWS to conserve and promote habitat for lesser long-nosed bats.
