Pocono Plateau · Zone 6a · ~2,000ft
The beech trees are dying. The gaps they leave are an opportunity. This guide — grounded in peer-reviewed research and field-tested recommendations — gives you everything you need to plant the right trees in the right places, whether you have an afternoon or a decade.
What's Happening
American beech — historically the dominant tree in these Pocono Plateau forests — is dying from a double blow: Beech Bark Disease (endemic for decades) and a newly arrived nematode called Beech Leaf Disease, which kills infected trees in 2–5 years with no available treatment. There is no resistant variety. The beech component of this forest is functionally done.
Black cherry on many properties is also in decline from black knot fungus (Apiosporina morbosa), a chronic native disease that girdles branches with hard black galls and spreads every spring from wild chokecherry across the landscape.
If nothing is planted into the opening canopy, the gaps fill with red maple, hay-scented fern, and invasive shrubs. The diverse, multi-generational forest disappears. The good news: these gaps are an invitation.
The Core Principle
Every plan on this site plants across multiple species and layers — not for aesthetics, but because structural diversity is what makes a forest resistant, self-reinforcing, and capable of lasting.
A specialist pathogen spreads through its host. When any species is 5–10% of the canopy instead of 30%, the disease burns out before it travels. Beech, ash, and chestnut all collapsed because they were abundant enough to sustain transmission. A diverse forest has no such target.
Trees in a healthy forest are connected by mycorrhizal fungi that transfer carbon, water, and nutrients between species. More species means more network connections. Seedlings planted near legacy trees tap into this system immediately — establishing faster and surviving drought better than isolated plantings.
Oaks support 500+ moth and butterfly species; cherry supports 450+. Almost all North American land birds raise their young on caterpillars — not berries. A diverse planting also staggers food resources across every season, from serviceberry in March to hawthorn berries in January. Tallamy & Shropshire 2009 →
The Approaches
The difference isn't how many trees you plant — it's whether you plant a complete diverse mix or only what the forest won't provide on its own.
Plant a complete, diverse forest
All ecological layers from the start. Scale to your budget — the same species mix works at every size.
Enter your tree count — the planner calculates the rest automatically. Every scale produces an ecologically complete planting.

For 5–10 acre properties. Manage conditions first, then buy only hickories, conifers, and the species that won't come on their own.
Individual tree protection and invasive removal do the heavy lifting. Plant in nucleation clusters — 59% forest cover achieved on 3% of site area in 19 years.

Penn State research on 85 Pennsylvania forest stands found that deer alone are responsible for more than 85% of regeneration failures. Address all three barriers before spending a dollar on seedlings.
The C-D-L Framework →Invasive shrubs, hay-scented fern, mountain laurel. Treat the season before planting.
One tube or cage per planted seedling. For properties under 50 acres, individual tree protection is the practical deer strategy. See the protection guide →
Open gaps needed for most canopy species. Release legacy trees from competition with crop tree release.
What to Plant
Every species listed is ecologically native to the Pocono Plateau at ~2,000ft. All have been validated against PA Flora, USFS Silvics, and current disease research.
Critical bat roost habitat. Pre-settlement dominant. Takes 50–70 years to reach bat-roosting size — plant now.
The primary replacement for dying beech on north-facing slopes. The gold standard of Appalachian fall color.
Native to this elevation. No natural seed source nearby — must be planted. North-facing slopes only.
The disease-free forest-interior dogwood. 40+ bird species use the berries. No anthracnose risk.
