PV Nature Biodiversity Standard

Overview

PV Nature is Plan Vivo's biodiversity standard for community led projects that restore or protect ecosystems. Its methodology and data protocol set out how projects establish a baseline, measure biodiversity change, and quantify benefits, and certified projects can issue and sell Plan Vivo Biodiversity Certificates. Certificate revenue funds project operating costs and local communities. A certificate represents a quantified, verified biodiversity outcome calculated under the Plan Vivo Biodiversity Certificate calculation protocol.

01 · Roles

The workflow as an explicit directed graph. In Graph each column is one role, so you can see who acts at each step; every node names the org.broadlistening.policy.block.* def it resolves to plus its input and output record. Data flow switches to a lineage view that makes explicit what data each node needs and makes, with dependency arcs tracing every record back to the node that produced it, including where the Darwin Core occurrence + measurement records feed in. Hover to trace, click to inspect; revise edges (dashed) send work back.

03 · Generated lexicon records

The records this methodology compiles to, ready to write to a PDS. The first tabs are the new policy engine records; the ★ claim.activity tab and those after it are reused ATProto Collective Funding Ecosystem records (org.hypercerts.*): the issued hypercert batch, its rights, an example verification attachment and a retirement receipt. The ◈ dwc.occurrence and ◈ dwc.measurement tabs are the Darwin Core field evidence the monitoring node writes; see the section below.
