Atlas technologists Jim Kooser, Wetlands and Natural Resources Practice Leader, Midwest and Northeast Regions and Eric S. Goddard, PWS, Ecological Resources Project Manager highlight the role of native soils in restoration. Strategic soil planning not only enhances ecological outcomes but also reduces costs through faster recovery and lower maintenance.��

Across the U.S., agencies are investing billions of dollars to restore wetlands, uplands and ecosystems as well as reclaim orphaned wells and redevelop brownfields. These initiatives carry high stakes: they reverse decades of land use impacts, improve stormwater management and help rebuild critical habitats. The most successful restoration strategies go deeper than what’s visible above ground. Lasting success depends on what happens beneath the surface. By addressing soil structure, restoring hydrology and supporting healthy nutrient cycles and microbial life, Atlas helps agencies and developers achieve outcomes that endure, cost less to maintain and deliver stronger returns on public investment.��

Why Soil Matters��

When restoration approaches prioritize speed and immediate cost savings, the result is compacted soil during earthmoving, the application of low-cost seed mixes quickly and considering the job complete as soon as something green appears. The outcome is predictable: invasive or undesirable species dominate while target native plants struggle in degraded soil conditions.����

Foundation Work Happens Underground��

Sustainable restoration begins with what you can’t see. Before any seed hits the ground, four critical soil factors determine project outcomes: soil structure, chemistry, biology and hydrology.����

Native soils function as complete ecosystems. Beyond basic sand, silt and clay, soil also contains organic matter and living microbial communities that cycle nutrients, regulate moisture, create structural microhabitats and strengthen plant resilience. Compaction and the removal of accumulated soil organic matter essentially break this biological engine, leaving restoration efforts to fight an uphill battle.����

The shift in approach is straightforward: address the soil foundation before vegetation establishment, and native species gain the competitive advantage they need to thrive in the long term.����

Practical Soil Development Strategies��

• Prevent Compaction Damage: Heavy machinery destroys soil structure with every pass. Instead, loosely pile materials and use low-pressure, tracked equipment for final grading. For severely compacted areas, the “push-up method” — creating aligned soil stacks with minimal pressure, then light grading — can restore essential porosity. Deep tilling to a depth of 2-4 feet optimizes the root growth capacity of trees, shrubs and meadow species.������

• Feed the Microbiome: Incorporate fine organic matter such as sawdust to increase soil carbon, enhance water retention and support beneficial microbes that aid native plant health and resilience. When possible, repurpose on-site tree and shrub material to reduce waste and naturally enrich the soil.����

• Balance Nutrient Chemistry: Test soil conditions before adding fertilizers. Former agricultural sites often contain excess nitrogen that fuels the growth of invasive species. Carbon-rich amendments can help rebalance these conditions, depriving non-native species of their preferred higher-nitrogen environment.����

Strategic Species Selection��

Match plant choices to restoration goals, whether that’s pollinator support, wildlife corridors, visual appeal or ecosystem reconstruction. In many cases it’s all the above. Regional native species offer proven compatibility with local soil and climate conditions.����

Maximize ecosystem resilience by incorporating plants with varied bloom periods and mature heights. Establish native meadows through drilling, broadcasting or hydroseeding techniques. In deep-tilled areas, combine tree and shrub planting with strategically placed brush piles made from site debris. These serve as wildlife refuges, carbon stores and seed banks that accelerate natural regeneration.����

Long-Term Performance Advantages��

Well-established native systems require minimal ongoing intervention. Initial watering and weed management may be necessary during the first growing season. After that, annual dormant season mowing often provides sufficient maintenance. Forested areas require some initial understory maintenance but become increasingly self-sustaining as canopy coverage develops.��

The broader benefits extend beyond reduced maintenance. Properly designed native systems control stormwater runoff, filter pollutants, support biodiversity and deliver measurable ecological value. These projects succeed not just by what gets planted, but by what flourishes over time.����

The Bottom Line��

Investing in soil strategy shifts the focus from short-term site turnover to long-term ecosystem health with aesthetic benefits. It requires more upfront planning, but the return on investment is clear: better environmental outcomes, fewer future interventions and measurable cost savings. Start with the soil, and you build a legacy that lasts.����
