Invasive silk tree spotted and confirmed in Conshohocken, Pennsylvania
iNaturalist: davidharrod
Invasive Species
Persian silk tree spreads readily from roadsides and yards into disturbed areas along streams and forest edges, so spotting one near you is worth logging because early range tracking is how communities get ahead of invasive spread before it becomes costly to manage.
Someone in Conshohocken, PA spotted a Persian silk tree and logged it on iNaturalist with enough photos and detail to earn 'research-grade' status. This tree, originally from Asia, is widely planted for its showy pink flowers but escapes cultivation and crowds out native plants. Each confirmed sighting helps scientists and land managers track where it's spreading.
