Ecological intelligence, embedded in landscape design decisions.

Generate plant communities
adapted to site's conditions and new climates

PerenOS is the ecological design software for climate-adaptive landscapes. It generates plant communities adapted to the specific conditions of a site and the climate it is moving into.

Conventional approach

Species first

Until now, species were selected from established knowledge and historical baselines. As climate conditions shift, plantings assembled this way carry increasing risk of failure.

→ New climates bring new conditions
Climate-adaptive approach

Functions first

The functions the site requires are named first. Species are selected as a guild capable of performing under the site's present and projected conditions.

PerenOS removes the time cost of ecological justification
and produces documentation ready for regulatory submission.

Time and fee recovery

PerenOS removes time pressure at specification stage by saving hours per project on:

  • ecological justification,
  • climate framing,
  • and species rationale,

that are produced upstream or downstream of spatial decisions.

Long-tail liability protection

Species selections are grounded in documented scientific and functional reasoning.

Where multi-year maintenance obligations apply, that documentation becomes the defensible decision.

Compliance documentation, ready to submit

PerenOS generates traceable community proposals calibrated to projected 2030–2060 conditions, structured for biodiversity net gain submissions, CSRD disclosure, TNFD reporting, and planning authority review.

PerenOS is designed for every practitioner
whose decisions shape land at scale.

The reasoning starts with the ecological function required on site,
then species are selected to answer the specific needs.

01
Entry at any stage of the project
Pre-design Mid-design Post-handover

PerenOS enters at whatever stage ecological reasoning remains open — before spatial decisions, after them, or alongside design software. Practitioners can define communities, take outputs into their CAD tool, and return to refine the design.

02
Community-scale reasoning, landscape-scale composition
Riparian Meadow Woodland

The design unit is the plant community. Species interactions, succession, and competition are modelled within each one — riparian edge, meadow zone, woodland margin — and reasoned about across the landscape as a whole.

03
Project accompaniment after handover
Establish Monitor Adapt

PerenOS stays with the project through establishment, monitoring, and adaptive maintenance. Where conditions diverge from projections, adaptations are proposed against the original reasoning record.

04
The output is a defensible argument
Inputs Trade-offs Uncertainty

Every output carries the reasoning that produced it: site inputs considered, trade-offs resolved, uncertainties named at the level of confidence available. The reasoning record itself is the documentation.

05
Practitioner judgment stays central
Propose Review Decide

PerenOS proposes, justifies, and surfaces uncertainty — but the practitioner holds the design decision. Outputs are arguments to evaluate, not specifications to accept.

Outputs trace to ecological science, name their uncertainties,
and add to a shared evidence base.

Scientific foundations
280,000+ taxa TRY Plant Trait Database Functional trait data across 280,000+ plant taxa, used to characterise species roles within modelled communities.
distribution modelling GBIF Global species occurrence records used to ground distribution modelling under current and projected climate conditions.
ERA5 · CMIP6 Climate projections ERA5 current conditions and CMIP6 scenario trajectories used to index community viability across each site's projected climate horizon.
National · global Soil and site data National and global soil datasets integrated with observed site conditions to anchor community selection in physical substrate.

Epistemic refusal

Where the evidence available is insufficient to produce a defensible recommendation, the platform states that explicitly and does not generate an output. All outputs are provisional. The practitioner's judgement takes precedence.

Observational Commons

PerenOS draws on a second knowledge layer: longitudinal observational data contributed by users across live projects. Every project recorded deepens the evidence base available to the next design decision. The knowledge base grows with use.

PerenOS is designed for every practitioner
whose decisions shape land at scale.

Landscape architects

What you receive

  • Community proposals with ecological reasoning explicit and traceable, ready for biodiversity net gain submissions and equivalent regulatory requirements across jurisdictions.
  • Climate-analogue species selection for design horizons beyond the reach of historical data.
  • Adaptive guidance that follows the project through establishment and long-term maintenance.
  • Field observation logging integrated into the site record from every visit.

Relevant pressures

Biodiversity net gain obligations
England's statutory 10% BNG requirement (February 2024) is the first legally mandated net gain framework to enter planning law. Equivalent obligations are now developing across Australia, South Africa, France, and multiple US states. The reasoning behind a planting proposal is increasingly part of the submission record, not only the spatial outcome.
Post-handover liability
Clients and regulators increasingly expect designed landscapes to perform ecologically over the life of the project, not only at the point of completion or handover.
Climate projection
Historical species lists are increasingly unsuitable for the conditions projected for 2040 to 2060, and practitioners are expected to document the basis for species selection against future conditions.

Ecological consultants

What you receive

  • Trait-based species selection grounded in global functional ecology datasets.
  • Explicit modelling of competitive dynamics and succession trajectories.
  • Regulatory framework integration across the jurisdictions you work in.
  • Longitudinal observation data that sharpens recommendations with each project.

Relevant pressures

Capacity ceiling
Demand for ecological input at the design stage consistently exceeds the hours available at project scale, across every market where biodiversity obligations are entering planning law.
Monitoring obligations
The EU Nature Restoration Law, biodiversity net gain frameworks, and CSRD all require ongoing ecological monitoring, not single-point assessments. The evidence burden is moving from design stage to lifetime performance.
Data continuity
Every project currently starts from scratch because no mechanism preserves ecological knowledge across the design, establishment, and long-term management phases.

Property developers

What you receive

  • Pre-application ecological modelling with reasoning explicit and traceable.
  • Documentation ready for planning submissions and regulatory review, across jurisdictions.
  • An adaptive maintenance plan that reduces non-compliance risk over the lifetime of the development.
  • Support for CSRD, ESRS E4, and TNFD reporting.

Relevant pressures

Biodiversity net gain, mandatory or approaching
Every major development in England must demonstrate 10% biodiversity net gain at planning consent (February 2024). Australia's Environment Protection Reform Act 2025 introduces an equivalent net gain test. South Africa's National Biodiversity Offset Guideline requires biodiversity offsetting under environmental authorisation. Multiple US states are developing analogous frameworks.
Lender requirements
Green finance instruments increasingly require ecological performance evidence, not only design intent. TNFD-aligned disclosure of nature-related financial risk is becoming standard for institutional lenders.
Post-handover liability
Poorly specified landscaping creates ecological compliance risk that persists for years beyond completion, particularly where regulatory monitoring obligations run with the land.

Planners and municipalities

What you receive

  • Site-specific ecological reasoning that can be defended to planning committees, oversight bodies, and the public.
  • Integration with ZAN, the EU Nature Restoration Law, urban biodiversity obligations, and equivalent frameworks across jurisdictions.
  • Long-term adaptive management guidance that follows the landscape through its lifetime.
  • Green infrastructure and urban heat island framing suited to institutional reporting and climate adaptation plans.

Relevant pressures

ZAN and urban planning obligations
France's zero net soil sealing law requires municipalities to integrate biodiversity restoration targets into SCoT and PLU planning documents, with obligations opposable from 2031.
EU Nature Restoration Law
Member states and their planning bodies are required to halt the decline of urban green space and integrate nature-based solutions into urban infrastructure, with binding targets from 2030.
Urban heat
Cities across multiple EU and global markets are now legally required to integrate nature-based cooling solutions into adaptation planning. The ecological quality of green infrastructure determines whether those solutions perform.

Infrastructure operators

What you receive

  • Community-level habitat design for linear, fragmented, and corridor sites, with reasoning adapted to each zone's conditions.
  • Ongoing monitoring integrated into asset management and reporting workflows.
  • TNFD and CSRD biodiversity disclosure support, with traceable documentation.
  • Climate-analogue species selection suited to infrastructure with 30-to-50-year design horizons.

Relevant pressures

TNFD and institutional investors
Nature-related financial disclosure is now expected by institutional investors for infrastructure asset holders. The ability to produce traceable ecological reasoning and longitudinal performance data directly supports TNFD-aligned reporting.
Ecological corridor obligations
Infrastructure verges and rights-of-way are increasingly identified as critical habitat corridors under national biodiversity strategies and the EU Nature Restoration Law. The ecological quality of those corridors is now a managed obligation, not a residual.
Climate exposure
Infrastructure designed to historical climate conditions faces performance degradation under projected 2040 to 2060 scenarios. Species selections that fail under future conditions create maintenance liability and ecological compliance risk across the asset's operating life.
Building in the open

Talk to us
before we build further.

PerenOS is in active development. Before the next round of build decisions is made, the team is speaking with professionals to understand how ecological reasoning actually fits into real working practice. These conversations directly shape what the platform becomes.

Research interviews run for 30 to 45 minutes, remote, and are held in full confidence.

Thank you. We will be in touch within a few days to arrange a time.
