FOUNDATIONAL CONCEPTS FOR ENHANCEMENT AND RESTORATION OF THE NATURAL COMMONS IN THE BUILT ENVIRONMENT: “The starting point for application of EAP, the Ecological Accounting Process, is recognition that local governments have existing tools in the form of policies and legislation for ‘maintenance and management’ (M&M) of ecological assets within riparian corridors,” wrote Tim Pringle, EAP Chair, in the report on the application of EAP to Shelly Creek on the east coast of Vancouver Island (February 2020)


“Until now, what local governments have lacked are a pragmatic methodology for financial valuation, and meaningful metrics that go to the heart of sustainable service delivery. EAP provides metrics that enable communities to appreciate the worth of ecological assets,” stated Tim Pringle. Six foundational and cascading concepts underpin the EAP methodology and provide a mind-map. The M&M acronym is a starting point for encouraging practitioners to think holistically about the relationship between hydrology and ecology.

A KEY TAKEAWAY FROM APPLICATION OF ECOLOGICAL ACCOUNTING PROCESS TO SHELLY CREEK VALUATION: “Over decades of disturbance, ‘riparian ecosystems’ have become reduced to ‘riparian zones’ as shown on the maps of today,” stated Peter Law, President of the Mid Vancouver Island Habitat Enhancement Society, in commenting on how ecological systems and services are compromised by land development


“An alternative term, riparian network, could also be used to describe a system composed of a physical stream channel and adjacent riparian (vegetated) corridor. This system provides a critical ecological function in linking terrestrial and aquatic ecosystems in a watershed or creekshed. A common history of land uses on the east coast of Vancouver Island and other regions in BC has been the fragmentation of the riparian network in both rural and urbanizing landscapes. Over decades of disturbance, a landscape’s ecological links/services decline as it’s economic (land use) linkages increase,” stated Peter Law.

A PROPERLY FUNCTIONING ‘NATURAL COMMONS’ SUPPORTS A PACKAGE OF ECOLOGICAL SERVICES: Ecological Accounting Process, EAP, is a pragmatic ‘made in British Columbia’ approach to financial valuation of the ecological services supplied by a stream


“The EAP program has three stages: Test / Refine / Mainstream. During 2017 and 2018, two Stage 1 demonstration applications tested the concept, and demonstrated EAP relevance to local government. In 2019, two Stage 2 demonstration applications resulted in working definitions and consistent application of the EAP methodology. In 2020 and 2021, six Stage 3 demonstration applications will mainstream use of EAP. The grand total of ten demonstration applications will encompass a range of land use situations in five regional districts,” stated Kim Stephens.

NATURAL ASSETS AS ECOLOGICAL SYSTEMS & SERVICES: “EAP demonstration applications have yielded three defining conclusions. These go to the heart of how practitioners look at the world around us,” says Tim Pringle, Chair, Ecological Accounting Process Initiative


EAP is the culmination of a 30-year journey by Tim Pringle. He has thought about and worked hard to develop and evolve a guiding philosophy, pragmatic strategy and meaningful metrics for valuing the services provided by nature. “Residents and property owners are familiar with constructed commons services – roads, potable water, storm sewers and many other ongoing services. They expect these services to endure. Similarly, communities expect the ecological services provided by the natural commons to be enduring,” stated Tim Pringle.
