Peatland Rewetting

DISCLAIMER - Real Science, Rewetting Sink + Biodiversity Honesty, No Bridge

Why no UTAC/CREP/AFET bridge: not only because the cited literature already provides the necessary quantitative structure -- a deliberate choice. This project's highly speculative AFET/UTAC experiments must never stand in the way of climate/ecology topics being accessible and usable to people who don't work inside that construct and aren't looking for renormalization groups. Real, checkable science, without the burden of an unproven framework. See PACKAGE_REGISTRY.md's "Why no UTAC/CREP/AFET bridge in the climate/ecology series" (2026-08-31) in the GenesisAeon workspace root for the full canonical note.

Status: Real, independently documented peatland-rewetting science (CO2 sink, methane rise, German Moorschutz strategy, fen biodiversity honesty). NO UTAC/CREP/AFET bridge.

Where this package came from

Built from Apps/Paket-Prompts_P130-P132.md section P131 only (2026-09-08), twin structure matching ocean-acidification-utac / permafrost-utac and sibling river-gauge-shipping-utac (P130) (constants, honesty is_*/does_*, hatchling, DISCLAIMER, CITATION.cff, README). Own package, not a P100/P107 extension (P100 is glacier-specific; P107 encodes drained-peat emissions rather than the rewetting sink direction).

What this is

Core-tier constants encoded exactly from the P131 prompt:

• Guenther, A. et al. (2020), Nature Communications 11, 1644,
• DOI: 10.1038/s41467-020-15499-z
• - temperate drained peat: CO2 = 10.3 t/ha/yr, CH4 = 7.9 kg/ha/yr
• - rewetted peat: CO2 = -0.4 t/ha/yr (net sink), CH4 = 205.9 kg/ha/yr
• - core message is qualitative / time-critical: earlier rewetting is
• better; methane rise does not

peatland-rewetting-utac

GenesisAeon Package 131 -- peatland rewetting: CO2 sink, methane rise, and biodiversity honesty (Guenther 2020, Nationale Moorschutzstrategie DE 2022, Kreyling 2021). Deliberately has no UTAC/CREP/AFET bridge -- see DISCLAIMER.md.

Own package, not a P100/P107 extension (P100 is glacier-specific; P107 has the wrong direction -- drained-peat emissions vs rewetting sink).

What's real here

• Guenther et al. (2020, Nature Communications)* -- DOI
• 10.1038/s41467-020-15499-z: drained temperate CO2 10.3 t/ha/yr,
• CH4 7.9 kg/ha/yr; rewetted CO2 -0.4 t/ha/yr (net sink),
• CH4 205.9 kg/ha/yr. Earlier rewetting is better; methane rise
• does not negate climate benefit if before 2050.
• 2024 Author Correction -- DOI 10.1038/s41467-024-47604-x:
• N2O-to-CO2 factor bug (14 vs 28) fixed; correction already applied
• to cited numbers.
• Nationale Moorschutzstrategie DE (2022-11-09, bmuv): at least
• 5 Mt CO2e/yr reduction by 2030; drained peat ~53 Mt CO2e/yr
• (~7.5% of German GHG).
• Kreyling et al. (2021, Nature Communications)* -- DOI
• 10.1038/s41467-021-25619-y: 320 vs 243 fen sites; Shannon
• 1.46+/-0.04 vs 1.75+/-0.04; 63% outside natural biodiv
• range; no convergence over three decades.

Explicitly omitted: unverified ~20 t CO2e/ha/yr savings figure (is_20_tonnes_per_hectare_figure_confirmed() -> False).

Quickstart

bash pip install peatland-rewetting-utac

```python from peatland_rewetting_utac import ( DRAINED_TEMPERATE_CO2_T_HA_YR, REWETTED_CO2_T_HA_YR, REWETTED_CH4_KG_HA_YR, is_rewetting_a_net_co2_sink, does_methane_increase_after_rewetting, does_methane_increase_negate_climate_benefit, does_rewetting_fully_restore_original_biodiversity, is_20_tonnes_per_hectare_figure_confirmed, )

print(DRAINED_TEMPERATE_CO2_T_HA_YR) # 10.3 print(REWETTED_CO2_T_HA_YR) # -0.4 print(REWETTED_CH4_KG_HA_YR) # 205.9 print(is_rewetting_a_net_co2_sink()) # True print(does_methane_increase_after_rewetting()) # True print(does_methane_increase_negate_climate_benefit()) # False print(does_rewetting_fully_restore_original_biodiversity()) # False print(is_20_tonnes_per_hectare_figure_confirmed()) # False ```
