Snatching defeat from the jaws of victory

Below is the full abstract from an excellent review of case material on river restoration in Newfoundland and Labrado, Canada:

Despite millions of dollars being spent annually to restore degraded river ecosystems, there exist relatively few assessments of the ecological effectiveness of projects. An evidence-based synthesis was conducted to describe river restoration activities in Newfoundland and Labrador. The synthesis identified 170 river restoration projects between 1949 and 2020. A practitioner’s survey was conducted on a subset of 91 projects to evaluate ecological success. When the perceived success of managers was compared to an independent assessment of ecological success, 82% of respondents believe the projects to be completely or somewhat successful whereas only 41% of projects were evaluated as ecologically successful through an independent assessment. Only 11% of practitioners’ evaluations used ecological indicators, yet managers of 66% of projects reported improvements in river ecosystems. This contradiction reveals a lack of the application of evidence to support value-based judgments by practitioners. Despite reporting that monitoring data were used in the assessment it is doubtful that any meaningful ecological assessment was conducted. If we are to improve the science of river restoration, projects must demonstrate evidence of ecological success to qualify as sound restoration. River restoration is a necessary tool to ensure the sustainability of river ecosystems. The assessment conducted in this study suggests that our approach to planning, designing, implementing, monitoring, and evaluating projects needs to improve. An integrated-systems view that gives attention to stakeholders’ values and scientific information concerning the potential consequences of alternative restoration actions on key ecosystem indicators is required.

My problem is not their main finding: “Despite reporting that monitoring data were used in the assessment it is doubtful that any meaningful ecological assessment was conducted.”

I can well believe it. What troubles me is that phrase, “only 41% of projects were evaluated as ecologically successful through an independent assessment.”

I don’t know what world the authors or you, the reader, live in. But in my world, a 40% success rate in river restoration projects is huge! I mean, really significant. Indeed, I come from a project implementation background where conjoining, “success” and “ecosystem restoration,” is like waving a red flag in front of a phalanx of critics at the ready to disagree.

This project victory (if indeed confirmed) is in no way to be characterized, I feel, as “only 41%”–a phrase repeated later in the body of the article.
