🌿 Native Plants, Stronger Shorelines A TVA‑Aligned Guide for Lake Nottely, Chatuge & Blue Ridge Homeowners

Our mountain lakes are some of the most beautiful in the Tennessee Valley — but they’re also some of the most sensitive. The narrow strip where land meets water, known as the riparian zone, does more work than most people realize. It filters runoff, stabilizes soil, cools the water, and supports the wildlife that keeps our lakes healthy.

According to TVA’s Native Plants Guide, the species recommended for our region were selected specifically for their ability to “restore, stabilize and enhance streambanks and shorelines, as well as improve aquatic, wetland, and terrestrial wildlife habitat.” For lake homeowners, that means one thing:

Native plants aren’t just pretty — they’re protective.

🌱 Why Native Plants Matter on TVA Shorelines

Native plants are naturally adapted to the Tennessee Valley’s soils, climate, and fluctuating lake levels. TVA notes that these species “commonly occur in waterfront, wetland, or aquatic areas and provide aesthetic, wildlife, or stabilization value.”

When you plant native vegetation along your shoreline, you’re helping:

• Reduce erosion from waves, wakes, and seasonal drawdowns

• Filter sediment and pollutants before they reach the lake

• Provide habitat for birds, fish, and small mammals

• Improve water quality for recreation and wildlife

• Lower maintenance needs because natives thrive here naturally

A healthy shoreline doesn’t look manicured — it looks layered, natural, and alive.

🌾 TVA‑Recommended Native Plants for Shoreline Stability

(All species below come directly from the TVA Native Plants Guide.)

Trees for Moist Uplands & Water’s Edge

These species anchor soil and tolerate fluctuating water levels:

• River Birch (Betula nigra) — Moisture-loving; great for stabilizing soft soils

• Black Willow (Salix nigra) — Thrives at the water’s edge and in standing water

• Sycamore (Platanus occidentalis) — Fast-growing with strong roots

• Sweetbay Magnolia (Magnolia virginiana) — Semi-evergreen; fragrant blooms

Shrubs That Build a Strong Buffer

Shrubs create mid‑level structure and wildlife habitat:

• Buttonbush (Cephalanthus occidentalis) — One of the few shrubs that grows in standing water

• Silky Dogwood (Cornus amomum) — Excellent for WE zones; blue fruits for birds

• Virginia Sweetspire (Itea virginica) — Fragrant white blooms; great erosion control

• Elderberry (Sambucus canadensis) — Forms colonies; stabilizes slopes

Grasses, Sedges & Rushes for Erosion Control

These are the workhorses of shoreline stabilization:

• River Oats (Chasmanthium latifolium) — Thrives in sun or shade; excellent stabilizer

• Soft Rush (Juncus effusus) — Common along wet edges; filters runoff

• Switchgrass (Panicum virgatum) — Deep roots; beautiful fall color

• Creeping Spikerush (Eleocharis palustris) — Forms colonies; great fish cover

Wetland Flowers for Color & Habitat

These species add beauty while supporting pollinators:

• Cardinal Flower (Lobelia cardinalis) — Hummingbird favorite

• Pickerelweed (Pontederia cordata) — Blue blooms; thrives in shallow water

• Swamp Milkweed (Asclepias incarnata) — Monarch-friendly

🛑 What NOT to Do on TVA Shorelines

TVA is very clear on this point: “Collecting plants from the wild should be avoided… and can be illegal without landowner permission.”

Also avoid:

• Mowing to the water’s edge

• Removing existing native vegetation

• Planting invasive ornamentals

• Hardening shorelines unnecessarily

A natural buffer is always the healthier, more resilient choice.

🌊 How to Restore Your Shoreline

1. Keep what’s already growing

Existing native vegetation is your best erosion control.

2. Add layers — trees, shrubs, grasses

A multi‑tiered buffer mimics natural shorelines and performs best.

3. Match plants to your site conditions

TVA uses these categories:

• DU = Dry Upland

• MU = Moist Upland

• WE = Water’s Edge

• W&SW = Wetlands & Standing Water

4. Buy from reputable local nurseries

TVA recommends sourcing “healthy plants from reputable nurseries located as close to your site as possible.”

💬 Final Takeaway

Healthy shorelines protect:

• Your property

• Your water quality

• Your wildlife

• Your lake community

Native plants are one of the simplest, most effective ways to care for the lake you love — and TVA has already done the homework for you.
