For lands and stewards, across time

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

The land you tend and the person you are on it form one system. PerenOS reasons from what that system requires: the functions the site needs to perform, the conditions it faces now, and those it is moving toward. What you observe across seasons enters the reasoning.

Conventional approach

Species first

Until now, species were chosen for the conditions your site has. The conditions it is moving into are different.

→ New climates bring new conditions.
Climate-adaptive approach

Functions first

The functions the site needs to perform are named first. Species are selected as a community capable of doing that work under your site's present conditions and those it is moving toward.

PerenOS is for the people who tend land,
on the scales they actually work.

If you hold the ecological intentbut the specific species for this soil, this microclimate, and this climate horizon remain the gap, PerenOS reasons about what those species are.

If food yield mattersPerenOS reasons about the productive plant community this soil can sustain and improve over time, including the species that build the conditions yield depends on.

If you want your land to hold for future generationsand planting is already in place, PerenOS reasons about what is there, what the system requires to hold together, and what needs to change to perform under the conditions it is moving into.

If the planting needs to be beautifulPerenOS treats that as a design requirement. Seasonal structure and visual character are outputs of the same ecological reasoning it applies to function.

If something that worked for years has stopped workingPerenOS reasons from what you observe now, diagnoses what the conditions your land is moving into require, and proposes the community suited to them.

What is a plant community?

A plant community is a group of species that grow together because their conditions, functions, and life cycles are compatible. The design unit in PerenOS is the community, not the individual plant.

They occupy different layers, support each other's establishment, and behave as a system over time.

How this relates to companion planting & guilds Show less

Gardening traditions name parts of this idea — companion planting names relationships between two or three species; guilds in permaculture describe a functional cluster around a central plant. Plant community is the ecological term for the whole assembly: its structure, its behaviour across seasons and years, and its relationship to site conditions.

What does climate-adaptive mean?

Climate-adaptive means every species PerenOS proposes is matched to where your site is going, not only where it is now. The climate reasoning spans 30 to 40 years.

The outputs serve the horizon you are working toward, whether it is a productive season, an established orchard, or a maturing woodland. Intermediate species may also be proposed: they perform adequately under current conditions and remain viable as conditions shift, bridging the transition.

Why proposals are site-specific Show less

This is because climate change has already altered the conditions on your site. Rainfall patterns, summer heat, frost timing, and soil moisture are no longer stable references across decades. Proposals are site-specific — PerenOS does not reason from regional averages, but from the conditions of your plot and the climate trajectory it sits within.

PerenOS reasons from the functions the planting needs to perform,
then selects species capable of performing them.

A planting can be asked to perform one ecological function or more, for example:

Anchoring slope & soil

Storing & releasing water

Supporting pollinators

Regenerating soil organic matter
