Using Budburst

Being part of BioBlitz! OK means you will become a citizen scientist!  As a citizen scientist, you will contribute data to our BioBlitz! OK inventory through the iNaturalist and eBird.

You will use Budburst to submit observations of the Redbud life cycle.

The Eastern Redbud (Cercis canadensis) was designated Oklahoma’s state tree in 1937 after Mamiee Lee Robinson Browne made it her mission to promote and protect this beautiful flowering tree.  Read more on the Oklahoma Historical Society webpage.

Observing Redbuds

Our phenology observations will focus on Eastern Redbud (Cercis canadensis), Oklahoma’s state tree.   Our observations will include the life cycle events that we can see during the spring: leafing, flowering, and fruiting.  Here are detailed descriptions of these events: phenophases of trees.

We encourage BioBlitz! OK participants to record these life cycle events several times during the month of April.  This will help scientists better understand how weather, climate, habitat, and location affect plants.
