Conservation advocates have long touted the need to preserve Sonoma County’s bucolic landscape, but a report released last week for first time assigned a dollar value to those open spaces and their natural resources.
The value of services provided by undeveloped and working lands, both public and private, in Sonoma County ranges from $2.2 to $6.6 billion annually, according to the report from the Healthy Lands and Healthy Economies Initiative. The study stems from a years-long collaboration between open space and conservation districts in Sonoma, Santa Clara and Santa Cruz counties.
“It’s clear that our community values open space and working lands, but the main point of the report is that not only do we value them, but these lands have an immense value that’s not commonly understood in the typical market framework,” said Karen Gaffney, conservation planning manager for the Sonoma County Agricultural Preservation and Open Space District.
The report assigns value to a variety of ecosystems. It accounts for green spaces that absorb runoff to curb flooding while filtering out pollutants. It highlights the benefit of soil, which captures and stores atmospheric carbon and sustains ground cover to prevent damaging erosion. It quantifies the public health benefit provided by trees and plants, which boost air quality, and of open spaces that harbor insect- and wildlife that can limit pests.
It’s the first clear picture of the total estimated value of Sonoma County’s “natural capital,” or its stock of natural assets, and the way they can provide cost-effective alternatives to man-made infrastructure.
