Microsoft’s backing of TealWaters crystallizes a simple, urgent idea: make the invisible visible. By pairing the Wetland Intrinsic Potential (WIP) approach with cloud-scale processing and modern machine learning, the collaboration aims to reveal wetlands that legacy maps miss—especially small, seasonal, and forest‑covered wetlands that play outsized roles in carbon storage, flood buffering, and biodiversity. The award from Microsoft’s AI for Good Lab funds high‑resolution, statewide mapping and model development for Washington, while the technical foundation draws on peer‑reviewed techniques that combine lidar, topographic indices, hydrologic proxies, multispectral imagery, and field validation into a probabilistic wetland surface. This shift—from coarse, binary inventories to probabilistic, uncertainty‑aware maps—could change how planners, tribes, and conservationists prioritize protection and restoration.

Wetlands are among the planet’s most valuable and imperiled ecosystems. A 2023 global reconstruction estimated that roughly 21% of inland wetlands have been lost since 1700, primarily to drainage and conversion for agriculture and settlement; the loss is concentrated in Europe, the United States, and China. That historical baseline reframes contemporary conservation priorities: protecting remaining wetlands and locating lost or remnant wetlands for restoration is central to climate mitigation and water resilience. (pubmed.ncbi.nlm.nih.gov, news.stanford.edu)
Despite their value, wetlands are often absent from conventional maps. Traditional inventories rely heavily on aerial photography and manual interpretation, which systematically undercount wetlands that are cryptic—under canopy, ephemeral, or lacking visible open water in the typical imagery used for mapping. This detection gap leaves public agencies, tribal stewards, and local planners without the datasets they need to make cost‑effective decisions about land use and restoration. TealWaters and similar research efforts are tackling this exact problem by combining process‑aware indicators of wetland presence with modern machine learning.
That cross‑stakeholder emphasis is important: TealWaters frames the technology as an amplifier—not a replacement—of local ecological expertise. Embedding tribal governance, conservation nonprofits, and regulatory users early increases the odds of practical uptake and helps identify sensitive use restrictions (for example, culturally sensitive sites that should not be publicly exposed).
That model accelerates impact, but it invites scrutiny. Public agencies will rightly question vendor lock‑in risks, the durability of cloud credits beyond grant periods, and accountability if models become de facto public infrastructure. Ensuring that the resulting datasets, code, and models are open, well‑documented, and exportable from a single vendor stack is critical to reduce dependency risks.
Meanwhile, global assessments underscore the economic and ecological stakes: multitrillion‑dollar losses are projected if wetlands continue to degrade at current rates, and recent intergovernmental reporting highlights rapid recent declines in many regions. Mapping is a necessary precondition for targeted restoration and policy action; without it, conservation remains reactive and inefficient. (reuters.com, pubmed.ncbi.nlm.nih.gov)
Yet success will depend on more than better models. It requires rigorous independent validation, careful governance around data sovereignty and misuse, transparent disclosure of uncertainty and compute footprints, and operational pathways for local governments to use probabilistic outputs safely. When paired with these guardrails, high‑resolution AI mapping can move wetlands from the category of “invisible liability” to visible public asset—a change that matters for carbon, flood resilience, biodiversity, and cultural survival. The science is promising; the policy and governance questions are now the bottleneck.

Background
Wetlands are among the planet’s most valuable and imperiled ecosystems. A 2023 global reconstruction estimated that roughly 21% of inland wetlands have been lost since 1700, primarily to drainage and conversion for agriculture and settlement; the loss is concentrated in Europe, the United States, and China. That historical baseline reframes contemporary conservation priorities: protecting remaining wetlands and locating lost or remnant wetlands for restoration is central to climate mitigation and water resilience. (pubmed.ncbi.nlm.nih.gov, news.stanford.edu)Despite their value, wetlands are often absent from conventional maps. Traditional inventories rely heavily on aerial photography and manual interpretation, which systematically undercount wetlands that are cryptic—under canopy, ephemeral, or lacking visible open water in the typical imagery used for mapping. This detection gap leaves public agencies, tribal stewards, and local planners without the datasets they need to make cost‑effective decisions about land use and restoration. TealWaters and similar research efforts are tackling this exact problem by combining process‑aware indicators of wetland presence with modern machine learning.
What exactly is being built: Wetland Intrinsic Potential and TealWaters’ stack
The Wetland Intrinsic Potential (WIP) concept
At the heart of TealWaters’ platform is the Wetland Intrinsic Potential (WIP) layer: a continuous probability surface that estimates how conducive each pixel of landscape is to supporting wetland conditions. WIP is conceptually distinct from direct detection; it infers likelihood using multiple lines of evidence—much as a field ecologist might infer wetland potential from vegetation, soils, and landscape position. The published WIP methodology uses a random‑forest model informed by:- Topographic indicators (multi‑scale microtopography from lidar/DEM derivatives).
- Hydrologic proxies (flow accumulation, distance to water, wetness indices).
- Vegetation and spectral indicators (multispectral and multisensor imagery).
- Land‑use and historical drainage records.
- Field‑verified training labels for supervised learning.
The TealWaters implementation: a cloud‑native mapping stack
TealWaters blends the WIP approach with additional product layers and cloud tooling:- High‑resolution inventories (1–5 m) for fine‑grained planning.
- Carbon potential mapping—identifying peatlands and other high‑carbon wetlands.
- Hydrologic drivers (surface and groundwater connectivity models).
- Temporal comparison layers to detect lost wetlands and restoration candidates.
- A cloud deployment architecture for scalable processing and county/state integration. (earthlab.uw.edu, technologymagazine.com)
Why Washington state matters as a testbed
Washington state offers a demanding mix of ecosystems—coastal marshes, temperate rainforests, inland peatlands, and urbanizing valleys—making it an ideal laboratory for generalizable models. TealWaters’ pilots include collaborations with the Tulalip Tribes, county planners, and state agencies to ensure outputs match real decision needs and local knowledge. Tribal partners are using the maps to prioritize culturally important restoration and subsistence landscapes (for huckleberries, salmon habitat, and floodplain reconnection), while small jurisdictions without wetland specialists can adopt high‑resolution layers to guide permitting and adaptation planning. (earthlab.uw.edu, technologymagazine.com)That cross‑stakeholder emphasis is important: TealWaters frames the technology as an amplifier—not a replacement—of local ecological expertise. Embedding tribal governance, conservation nonprofits, and regulatory users early increases the odds of practical uptake and helps identify sensitive use restrictions (for example, culturally sensitive sites that should not be publicly exposed).
The measurable benefits: carbon, floods, biodiversity, and cost savings
Accurate, high‑resolution wetland maps unlock several near‑term benefits:- Improved carbon accounting: Identifying peatlands and other carbon‑dense wetlands is essential to avoid emissions from drainage and to target protection of high‑value carbon sinks. Early TealWaters work specifically targets a statewide map of high‑carbon wetlands.
- Nature‑based flood mitigation: Restoring wetlands in strategic catchments reduces peak flows and infrastructure costs; maps let planners cost‑effectively prioritize sites.
- Biodiversity and cultural outcomes: Wetlands mapped across tribal lands help direct habitat restoration that supports fisheries, traditional plant foods, and culturally significant landscapes.
- Operational savings for local governments: Counties and small cities can avoid expensive consultant inventories and instead use reproducible, open layers integrated into GIS workflows.
The science check: strengths, limits, and verification
Strengths supported by peer‑review
The WIP approach is grounded in a peer‑reviewed methodology that explicitly addresses the known blind spots of traditional mapping: canopy occlusion, ephemeral wetlands, and hydrologically driven systems. The HESS paper documenting WIP shows robust accuracy in field tests and demonstrates how multi‑scale topographic indicators materially improve detection of cryptic wetlands. These are not novel claims pulled from marketing copy; they rest on reproducible, published research.Key limitations and where caution is required
- Regional generalization: Models trained on the Pacific Northwest’s temperate landscapes may not generalize reliably to tropical peatlands, arctic permafrost wetlands, or heavily agricultural regions without retraining and region‑specific ground truth. Extrapolating a Washington‑trained model globally risks false negatives or positives.
- Data availability: High‑resolution lidar, seasonal radar, and multisensor time series are unevenly available across jurisdictions. When input layers are missing or dated, model performance degrades. Finding, licensing, and processing these large datasets is nontrivial.
- Temporal dynamics and uncertainty: Wetlands cycle seasonally and respond to interannual climate variability. Static binary maps mislead; probabilistic outputs and per‑pixel uncertainty metrics are essential if maps are to be used for permitting or legal decisions.
- Carbon estimation confidence: Estimating carbon stocks from remote sensing requires ecological allometries and field cores to calibrate models. Landscape-scale carbon maps will carry wide confidence intervals absent systematic coring campaigns. TealWaters recognizes this and couples carbon potential mapping with targeted sampling plans.
Verification and independent validation
To be credible in regulatory and market settings, AI‑driven wetland maps need independent validation. Practical expectations include:- Public confusion matrices and regional accuracy breakdowns.
- Out‑of‑sample tests across ecoregions and seasons.
- Third‑party audits or validation campaigns funded by agencies or foundations.
Governance, ethics and operational risks
Data sovereignty and Indigenous rights
Mapping on tribal lands raises immediate questions about who controls the data. Tribal partners often require governance clauses that keep culturally sensitive geolocations private and that return authority to Indigenous stewards. Ethical deployment means offering fine‑grained access controls, opt‑in publication policies, and clear licensing that prevents commercial exploitation without tribal consent. TealWaters has prioritized partnerships with tribes, but formal data sovereignty mechanisms must be contractual and technical.Enabled emissions and lifecycle costs
Large cloud‑based AI projects have a carbon footprint from compute and storage. Conservation gains must be weighed against enabled emissions—the indirect emissions resulting when technology makes extractive activities easier or when the compute itself is carbon‑intensive. Funders should require disclosure of compute carbon footprints and mitigation strategies (e.g., renewable‑backed credits, model distillation to reduce inference load).Misuse and perverse incentives
High‑resolution maps could be misused: developers or extractive actors might exploit precise data to circumvent consultation processes or speed land conversion where public oversight is weak. Similarly, maps could inadvertently be weaponized for land speculation if published without legal and governance guardrails. Open data is invaluable, but uncontrolled release without institutional safeguards can do harm. Policy design must connect spatial outputs to legal standards and civic oversight.Overconfidence: maps are probabilistic tools, not legal designations
A WIP probability is a scientific signal—not a regulatory determination. Misinterpreting probabilities as legal status risks blocking legitimate development or giving false assurance where protection is needed. Agencies should adopt thresholded maps only after explicit rules, uncertainty annotations, and operational guidance are published alongside training materials for decision‑makers.Practical recommendations: how to make AI wetland maps operational and trustworthy
- Require uncertainty‑aware outputs: Every pixel should carry a probability and a documented confidence interval. Use graded thresholds and decision rules tied to those probabilities.
- Fund independent validation: State agencies or third‑party researchers should run blind validation campaigns across ecoregions before adoption for permitting.
- Deploy data sovereignty and access controls: Contractual provisions and technical access layers must let tribes and communities control sensitive geodata.
- Publish performance metrics and reproducible pipelines: Open confusion matrices, training data summaries, and containerized processing pipelines so external auditors can reproduce results.
- Audit compute footprint: Disclose cloud compute usage and mitigation strategies; favor model efficiencies and renewable energy backstops.
- Build practitioner guidance and training: Provide short, practical guides for planners and regulators on how to interpret probability surfaces and integrate them into permit reviews.
The broader context: why corporate‑backed conservation tech matters (and what to watch)
Microsoft’s AI for Good Lab has positioned itself as a grantmaker and technical partner to domain researchers—awarding $5 million across Washington organizations and pairing grants with Azure credits and lab expertise. This blended model accelerates adoption by lowering infrastructure barriers and offering production‑grade tooling to academic teams. The TealWaters award is a concrete example of that approach. (news.microsoft.com, blogs.microsoft.com)That model accelerates impact, but it invites scrutiny. Public agencies will rightly question vendor lock‑in risks, the durability of cloud credits beyond grant periods, and accountability if models become de facto public infrastructure. Ensuring that the resulting datasets, code, and models are open, well‑documented, and exportable from a single vendor stack is critical to reduce dependency risks.
Meanwhile, global assessments underscore the economic and ecological stakes: multitrillion‑dollar losses are projected if wetlands continue to degrade at current rates, and recent intergovernmental reporting highlights rapid recent declines in many regions. Mapping is a necessary precondition for targeted restoration and policy action; without it, conservation remains reactive and inefficient. (reuters.com, pubmed.ncbi.nlm.nih.gov)
Case study highlights: early signs from pilots and partners
- Tulalip Tribes: Using TealWaters outputs to prioritize restoration of salmon rearing habitats, huckleberry patches, and floodplain reconnection projects—work that supports both cultural continuity and ecological resilience. Tribal staff emphasize that AI helps process voluminous data while local knowledge still guides interpretation and action. (technologymagazine.com, earthlab.uw.edu)
- State and county integration: Washington Department of Ecology and county planners are targeted integration partners, aimed at embedding high‑resolution layers into permitting and climate adaptation planning. If these integrations succeed, they represent a replicable procurement model for other states.
- Research verification: The WIP methodology’s Hoh River watershed test shows how combining lidar microtopography and multisensor data yields step‑change improvements in detecting cryptic wetlands—evidence that the scientific approach scales when quality inputs and ground truth are present.
Conclusion: realistic promise, guarded optimism
The Microsoft–TealWaters partnership exemplifies how AI mapping and machine learning can address a practical, high‑impact conservation gap: revealing wetlands that traditional mapping misses and turning that visibility into better protection, restoration, and climate accounting. The project combines a strong scientific foundation (the WIP methodology), concrete funding and cloud support from a major corporate lab, and meaningful engagements with tribal and state partners—ingredients that increase the odds of real impact. (hess.copernicus.org, blogs.microsoft.com)Yet success will depend on more than better models. It requires rigorous independent validation, careful governance around data sovereignty and misuse, transparent disclosure of uncertainty and compute footprints, and operational pathways for local governments to use probabilistic outputs safely. When paired with these guardrails, high‑resolution AI mapping can move wetlands from the category of “invisible liability” to visible public asset—a change that matters for carbon, flood resilience, biodiversity, and cultural survival. The science is promising; the policy and governance questions are now the bottleneck.
