Identify • Report • Control
This page is a Delaware companion to our national guide: Invasive Tree Species (Weed Trees). Use it to confirm what’s considered invasive in Delaware, verify identification, and find the most useful mapping and reporting tools.
Fast path: get photos → confirm ID → check inventories/maps → report → choose control + follow-up. The goal is to prevent spread (seeds and vegetative fragments) and avoid “cut-and-sprout” failures.
Jump to: quick links • common invasive trees • verify & report • control playbook • FAQs
These are the fastest paths to “Is this invasive here?” and “Who should I tell?”
Invasive Tree Species (Weed Trees) — definitions, red flags, and prevention.
Official invasive plant list and state guidance.
Report + map sightings (use photos + precise location).
Tip: before you remove a tree, confirm ID. Many invasive trees resprout aggressively when cut. The best outcomes come from correct timing + follow-up monitoring.
