- Description: Interviews across nine projects show that permitting, utilities, site constraints and long-term stewardship funding can be as decisive as ecological design.

Evidence

Peer-reviewed

Geography

California Bay-Delta, USA

System

Developed estuarine wetlands

## WHAT THE EVIDENCE SAYS

Interviews with 59 project developers, managers, funders and policymakers across nine restoration projects found barriers split between site-level and higher-scale causes. Common problems included conflicts among regulatory authorities, physical constraints from the built environment, and insufficient funding for post-project stewardship.

## WHY IT MATTERS / OUR READ

Nature-based infrastructure is not implemented on an empty map. Easements, utilities, elevation, salinity, permitting authority and long-term maintenance finance are part of the ecological feasibility of a restoration project, not administrative details outside the system.

## CAVEATS / UNCERTAINTY

The study documents reported barriers among projects that advanced far enough to study; it lacks a counterfactual sample of projects that failed or never began and is subject to interview recall bias.
