Trending: Osoberry (Oemleria cerasiformis) — 135 observations this week

iNaturalist Community

Summary

iNaturalist

Why it matters This matters because osoberry is a bellwether of spring — if you live in the Pacific Northwest, seeing it bloom means pollinators are waking up and the gardening season is truly underway, and crowd-sourced observations like these help scientists detect whether that timing is shifting earlier each year due to climate change.

Osoberry is a native shrub that grows along the West Coast of North America and is one of the very first plants to leaf out and flower in late winter or early spring. This week, 135 people submitted verified sightings of it to iNaturalist, the popular nature-tracking app, making it a trending plant right now. All those observations together paint a picture of where and when osoberry is blooming across its range — valuable data for understanding how spring is changing over time.

Osoberry, one of the first native shrubs to bloom each spring in the Pacific Northwest, drew 135 research-grade observations on iNaturalist this week, making it one of the most-watched plants right now. This surge in citizen science data helps track how early this early-blooming species is leafing out and flowering across its range.

Key Findings

1

135 research-grade observations were recorded this week, qualifying osoberry as one of the most-observed plant species on iNaturalist during this period.

2
