Peat Webinar / Protocol Questions

The Protocol sets no minimum project acreage, leaving room for projects on the scale of tens of acres. In practice, small properties face three constraints: sufficient peat depth to meet the Protocol's eligibility threshold (§5.1), the ability to manage hydrology without adversely affecting neighboring land, and generating enough credit volume to justify monitoring and infrastructure costs. For most small or partial landowners, the strongest path forward is coordinating with neighboring owners within the same hydrologic system to register as a unified project. AEI expects to develop landowner-facing guidance to support this kind of coordination.

Pocosins historically covered an estimated 1 million hectares in the eastern United States. Approximately 70-80% has been ditched and drained for forestry, agriculture, or peat extraction, much of it now fallow or under crop production on pocosin soils. AEI has inventoried drained and degraded pocosin acreage across North Carolina and the broader Southeast to estimate the scale of eligible land, and continues to evaluate additional properties as adoption of this protocol scales.

The Protocol is designed to restrict activities that would compromise restored hydrology, alter peat chemistry, or physically disturb the peat — not general land use. Prohibited activities include new ditching or drainage, water diversion from outside the property, timber harvest (except limited harvest tied to restoring native pocosin vegetation), and soil disturbance beyond a small footprint tied to water-control infrastructure. The Protocol's preferred legal instrument, a deed restriction rather than a full conservation easement, is intentionally chosen to preserve landowner flexibility for other compatible uses. Activities like hunting, which don't disturb hydrology or peat, are generally consistent with this framework, though final terms are established in each project's specific legal instrument.

AEI is developing landowner-facing resources to support participation, including a concise overview document summarizing the program, eligibility, and the general process for prospective landowners to share with neighbors or peers. AEI aims to work closely with local universities, land trusts, farming associations, and other institutions to find the best path to communicating restoration and economic opportunities afforded by the protocol. Interested landowners and organizations are encouraged to contact AEI.

The Re-Vaulting framework is built on the underlying physical logic of restoring a saturated, anoxic natural vault — a mechanism common to peatlands generally, not just pocosins. Version 1.0 is calibrated specifically to pocosin chemistry and hydrology in the Atlantic Coastal Plain. Thus, the Richardson/Flanagan Proxy and its default parameters are not portable to other peatland types. Replicating this methodology for other peatland systems with region-specific input data (e.g., bulk density, carbon content, decay rates) and a re-calibrated proxy relationship could offer potential for new methodologies. However, there is no plan currently to develop these.

Both pools represent carbon genuinely leaving the atmosphere or the active carbon cycle, so both qualify as removals under the Protocol's framework. ABA reflects direct atmospheric uptake through new plant growth — the same removal logic used in forestry and grassland protocols. VLPR reflects a different but equally valid removal pathway: legacy peat carbon is returned to durable, protected storage, halting its active release from the soil carbon cycle. This mirrors established biomass-burial and biochar removal protocols, where carbon is considered removed once storage is sealed, and re-emitted volumes are deducted if that seal later fails.

Most existing peatland-rewetting methodologies, including Verra's VM0027/VM0036 and the IUCN Peatland Code, credit rewetting as an avoided emission using regional or generic emission factors. This Protocol instead credits the vulnerable legacy peat carbon itself as a verified removal — carbon returned to durable, protected storage — using the pocosin-specific Volumetric Legacy Peat Re-Vaulting (VLPR) method. It's grounded in peer-reviewed, pocosin-specific field science rather than generalized peatland assumptions, including directly measured methane and nitrous-oxide behavior unique to pocosin chemistry. The removal framework is mechanistically consistent with recognized biomass-burial and biochar removal methodologies used elsewhere in carbon markets, applying the same reversal-and-repair logic to a naturally occurring, rather than engineered, storage vault.

Recalcitrance and imminent loss describe different things. Pocosin peat's phenolic, antimicrobial chemistry genuinely slows decomposition — laboratory work swapping pore water between northern and southern peats showed pocosin chemistry alone suppresses decay rates by roughly 50–60% relative to northern, sphagnum-derived peat. That's why pocosin peat persists for millennia under saturated conditions and decays more slowly than other peat types even when drained. But slower is not stopped: under the Protocol's calculated decay rate, the active 60 cm oxic zone is modeled to fully oxidize within approximately 78 years absent intervention — an active, ongoing loss, not a stable equilibrium. The zero baseline reflects that trajectory, not an assumption that peat vanishes overnight.

The Protocol requires developers to document ecological co-benefits — biodiversity, water quality, flood attenuation — as part of standard reporting, though these are not monetized as carbon credits. The Protocol does not prohibit developers from separately pursuing biodiversity or other ecosystem-service credits, provided any overlapping program confirms it isn't also claiming the carbon-removal benefit. Whether other types of credits are available, however, will depend on those systems’ eligibility and additionality rules. Developers should evaluate this independently before assuming co-benefits translate into a second revenue stream.

The Protocol assumes water-control infrastructure remains in place and functional for the full 100-year commitment period, backed by a perpetual maintenance endowment sized to fund inspection, repair, and periodic structure replacement (roughly every 30–50 years). There is no current pathway to decommission structures or rely on unmanaged hydrology.

The underlying obstacle is largely physical and regulatory rather than ecological: the drainage ditches on most pocosin sites are large — commonly 50 feet wide and 10-15 feet deep — and are classified as jurisdictional waters of the U.S., making full backfilling both prohibitively expensive and regulatorily complex. Backfilling also can't use ordinary fill material in a wetland setting; suitable peat fill would have to come from another peatland, defeating the purpose. That said, some natural infilling of shallower ditches is expected over time as they're removed from active flow.

The Protocol treats storm and hurricane damage as a recognized reversal risk, not a program-ending event. If water-control structures are damaged or fail — from a hurricane, flooding, or other cause — the affected area is taken offline for crediting purposes until repairs restore proper function; no new credits accrue during that period, and any resulting carbon loss is measured and deducted. Financial protection against this risk comes from two layers: a minimum 20% reversal buffer withheld from issued credits at the outset, and a required perpetual maintenance endowment sized to fund inspection, repair, and eventual replacement of infrastructure over the full 100-year commitment. Projects must also disclose and manage flooding-related risks, including saltwater intrusion and storm surge in low-elevation sites, as part of standard risk planning.

Fire risk in pocosin peat is strongly governed by hydrologic condition rather than acting as a fixed addition to the oxidation timeline. In wet or rewetted peat, fire losses are minor — typically limited to a few centimeters of the surface duff layer, which regenerates quickly. In drained peat, fire behaves very differently: dry peat can sustain deep, smoldering combustion that burns well down through the soil profile, causing substantial additional carbon loss beyond ongoing oxidation. Field evidence, including centuries-old pond pines with buried root systems, shows peat accumulation persisting through periodic fire events under wetter conditions. Rewetting substantially reduces, though does not eliminate, the risk of severe fire-driven carbon loss.

The Protocol targets a water table of −20 to −30 cm below the peat surface, maintained seasonally rather than as a fixed year-round depth. This range is designed to re-saturate the peat profile (but not inundate), preserving the natural pocosin chemistry while substantially reducing oxidative carbon loss and suppressing the sustained smoldering combustion responsible for catastrophic peat fires. Because pocosin surfaces are naturally domed and uneven, actual water-table depth varies across a site even under successful restoration; capillary action keeps peat moist even where the table itself sits below target. For this reason, compliance is assessed continuously against monitored water-table depth and solar radiation rather than a single fixed number. Re-wetting to this target is not intended to eliminate natural, shallow, ecologically beneficial ground fires — only to prevent the deep, catastrophic burns associated with drained conditions.

The two mechanisms serve different timeframes. The reversal buffer — a minimum 20% of issued credits withheld at the outset — acts as immediate insurance against events like hurricane damage, structure failure, or unintended flooding, and is drawn down to cover losses if a reversal occurs. The endowment is a separate, dedicated fund built over time from credit revenue, sized to cover inspection, repair, and eventual replacement of infrastructure for the full 100-year commitment, accounting for inflation, fees, and equipment life. As the endowment becomes fully funded — required by year 20 — the required buffer percentage is expected to decrease, since durable funding for maintenance reduces the ongoing risk the buffer exists to cover. In effect, the buffer covers near-term shocks while the endowment funds long-term stewardship, and reduced buffer requirements over time reflect growing confidence that maintenance is durably financed.

The Protocol is built around direct, field-measured data rather than generalized regional defaults. Both the legacy peat pool (VLPR) and the annual accrual (ABA) are grounded in the Richardson/Flanagan Proxy — a regression model calibrated from over 17,000 half-hourly eddy-covariance flux measurements at pocosin sites — and every project must substitute its own monitored water-table depth and solar radiation data before credits can be issued, rather than relying on illustrative defaults. Direct eddy-covariance flux confirmation is mandatory at baseline and through the first two years of every project to validate that project's specific proxy relationship. All monitoring data, calculations, and the credit calculator itself are submitted in traceable, formula-intact spreadsheet form to an independent third-party verifier, and results are made publicly accessible. This reliance on direct flux measurement and mandatory project-specific calibration — rather than fixed regional emission factors — distinguishes the protocol's verification approach from methodologies that rely more heavily on generalized modeling.
