Invasive species establish quickly where soil is disturbed—road cuts, utility corridors, logging edges, gravel bars, and riparian buffers. River systems such as the Ohio, Kanawha, Monongahela, and New River corridors can move seed and plant fragments downstream, while sunny openings on slopes create ideal establishment sites.
Interchanges, shoulders, and staging areas create seed sources that spread into neighborhoods, farms, and forest edges.
Repeated mowing and disturbance favors fast colonizers; edges can seed adjacent backyards and field margins.
High water can move seed and fragments; disturbed banks and gravel bars become reinvasion hotspots.
Use the quick ID cues below to confirm what you’re seeing on slopes, along corridors, and at property edges.
Quick ID: Long compound leaves; papery winged seeds; smooth gray bark on young trees; strong odor when crushed.
Habitats: Road cuts, rail edges, utility corridors, vacant lots, and forest edges—especially near interchanges and redevelopment sites.
Why harmful: Aggressive resprouter that forms thickets, suppresses native regeneration, and spreads quickly after disturbance.
Spreads by: Wind-dispersed seed plus vigorous root suckering (often worse after cutting or soil disturbance).
Quick ID: Very large heart-shaped leaves; showy purple spring flowers; persistent seed capsules.
Habitats: Steep disturbed slopes, quarry edges, streambanks, and openings—common where bare soil is exposed.
Why harmful: Fast colonizer of disturbed sites; can dominate openings and reduce native pioneer tree establishment.
Spreads by: Abundant wind-dispersed seed that establishes readily on bare soil and thin rocky substrates.
Quick ID: White spring blossoms; glossy oval leaves; small hard pears; wild plants often thorny.
Habitats: Subdivisions, town edges, roadsides, and farm field margins—often escaping from ornamental plantings.
Why harmful: Forms thorny thickets that crowd out natives and complicate mowing and pasture/field access.
Spreads by: Bird-dispersed fruit spreads rapidly from planted neighborhoods into fields and forest edges.
These plants often show up in shaded woods, along streams, and on farm edges—especially where groundcover has been disturbed.
Shade-tolerant annual grass that blankets trails and forest edges, suppressing native wildflowers and tree seedlings.
Dense streambank stands that spread by rhizomes and fragments—avoid moving soil from infested sites.
Thorny shrub that invades fencerows and field edges; reduces pasture access and outcompetes native shrubs.
Most invasive introductions are accidental: legacy ornamentals, volunteer seedlings in containers, contaminated mulch/soil, and moving fill from corridor projects. Reducing these pathways protects customers and lowers long-term maintenance costs for HOAs, parks, and farm properties.
Check pots for volunteer seedlings (especially tree-of-heaven and pear). Quarantine and remove before sale or installation.
Source mulch/soil from reputable suppliers and avoid importing fill from infested sites without screening and a follow-up plan.
Recommend serviceberry, redbud, river birch, native oaks, and spicebush depending on site moisture and sun exposure.
Aim for a repeatable workflow: confirm the ID, contain spread, remove at the right time, dispose safely, then replant quickly. In West Virginia, removal is often most effective in spring or fall, with follow-up control to catch resprouts and seedlings.
Photograph leaves, bark, flowers, and seed/fruit. Verify before removing large trees or working near waterways.
Bag seed pods/fruit. Avoid moving contaminated soil or brush into woods, streams, or parks.
Seedlings: pull early. Resprouters: do not rely on cutting alone. Plan multi-season follow-up.
Start at edges: fencerows, lanes, ditches, staging areas, and sunny field margins near specialty crops.
On steep ground, replant quickly and use mulch/erosion control so invasives don’t re-colonize bare soil.
Keep seed-bearing debris contained and follow local disposal guidance—never dump yard waste into woods or waterways.
Choose natives matched to your site (yard, farm edge, riparian buffer, or slope) to stabilize soil and reduce reinvasion.
Small yard tree with early-season blooms; strong native value.
Great replacement for ornamental pears; wildlife-friendly fruit.
Excellent along streams and wetter soils; stabilizes banks.
Keystone canopy tree where space allows; supports biodiversity.
Native understory shrub for woodland edges and restoration.
Tough native with great fall color; good for many WV sites.
