We are aware of some issues that observers are experiencing with the Nature's Notebook app syncing. We have identified the source of this issue and implemented a fix. If you experience this sync issue, please try deleting and reinstalling the app, which will prompt you to log in again. If you continue to experience problems, please reach out to support@usanpn.org.

We understand that this interim solution may not be ideal, and we greatly appreciate your patience as we transition to this new phase of the NPN. We are continuously working on updates and improvements to our new site and current app.

Generally, a 13-year brood emerges in the same year as a 17-year brood roughly every 5-6 years, though most of the 17-year broods are not in contact with a 13-year brood, so the different cicadas are clearly separated in space. A co-emergence involving adjacent broods of different life cycles is something that happens only roughly every 25 years. Any two specific broods of different life cycles co-emerge only every 221 years. It may be a good year to invest in some ear plugs!

Resting buds transitioning out of dormancy - which buds are which? What are the cues? When do I start reporting? The cues for a plant’s transition from dormancy to renewed activity can be subtle, yet can be quite visible if you are watching closely. It may take careful sleuthing—and sometimes previous experience—to detect the early stages. The tightly clasping bud scales of the dormant buds—or tightly packed leaves of naked buds—begin to shift or ever-so-slightly "swell" and may also shift color. These signals suggest that reporting on "Breaking leaf buds" and "Flowers and flower buds" is not long off.

Vernal, or Ozark, witch hazel is among the earliest blooming native plants of Missouri. Its blooms, small flowers often hidden by persistent old foliage, provide sustenance and shelter to over wintering pollinators. While typically vernal witch hazel starts blooming midwinter, warm temperatures started an early bloom! By joining this initiative, each observer becomes a vital part of a larger effort to create a record of Vernal Witch Hazel growth across different regions of Missouri.
