Who we are

A holon is a whole that is also a part.

Conservation is already happening in this city, and almost none of it is called that. We call it urban conservation, and we know the word is borrowed: in a city the work is more than ecological.

Land conservation grew up inside a few disciplines. A front yard is a habitat, a rain catchment, a meeting place, a parcel, a budget and a record at once, and it never holds still. It needs someone whose subject is how the parts relate.

We are engineers and systems people who spent our working lives inside industries where mistakes are expensive, and we came to this work from there, with a great deal to learn from the people who came from ecology.

In one year, before any grant, we built the first parts of what a city of small keepers needs: a standard that measures ten dimensions and never adds them up, a catalog of more than fifty promises a neighbor can make about their own ground, a way for neighbors to witness each other's work that pays the same for a yes and a no, a privacy architecture written before the first round is walked, the networks, the knowledge, and the software that holds it.

Our work is to bring urban conservation to the level it deserves: a shared standard, the record, a way to trust it without a center, and rules that belong to the people who live under them.

Where things stand

This is what exists, and the date we last said so.

Foundations, companies and civic institutions can anchor this from the start. The method, the record and the software already exist, built before any grant; a first gift funds their first use. We will bring the full plan, the budget, and the written conditions under which we would stop.

Where we stand

On the shoulders of people who started earlier.

NPSOT Houston has done native-plant-knowledge work for decades. Homegrown National Park reframed the front yard before us. The Xerces Society, Wild Ones, and generations of growers carried this. Our work is downstream of theirs, and we say so on purpose.
