Cultural and Natural Assets for Willamette Basin, Oregon Sustainability
نویسنده
چکیده
In this paper, we consider the transfer of environmental and cultural assets to the next generation as a potential measure of sustainability. We define “net assets” as the value of renewable and nonrenewable natural resources plus humanmade, intellectual, social, and cultural capital, minus any debts. We apply this approach by first reviewing survey data reflecting how cultural capital may yield microbehaviors that add up to the macroresults of environmental protection and restoration. Second, we evaluate how human activities play out on the landscape. Rather than a dollar measure of assets, historical changes in land use are a proxy for asset change. A broad look at the Willamette Valley, Oregon’s most urban and industrial area, shows that capital in forest lands has shifted from significant loss to improvement, agricultural lands have decreased only slightly, and urban development has taken a relatively small share of the total landscape. However, sprawl is increasing despite efforts to contain urban growth. Looking at highly valuable ecological features for the future, we find that wetlands continue to be lost, important species are endangered, and the secondary impact of urbanization on the landscape is increasing.

متن کاملThe population structure and recent colonization history of Oregon threespine stickleback determined using restriction-site associated DNA-sequencing.
Understanding how genetic variation is partitioned across genomes within and among populations is a fundamental problem in ecological and evolutionary genetics. To address this problem, we studied the threespine stickleback fish, which has repeatedly undergone parallel phenotypic and genetic differentiation when oceanic fish have invaded freshwater habitats. While significant evolutionary genet...
متن کاملMapping and valuing ecosystem services as an approach for conservation and natural-resource management.
Current approaches to conservation and natural-resource management often focus on single objectives, resulting in many unintended consequences. These outcomes often affect society through unaccounted-for ecosystem services. A major challenge in moving to a more ecosystem-based approach to management that would avoid such societal damages is the creation of practical tools that bring a scientifi...
متن کاملBody morphology differs in wild juvenile Chinook salmon Oncorhynchus tshawytscha that express different migratory phenotypes in the Willamette River, Oregon, U.S.A.
Body morphology of juvenile Chinook salmon Oncorhynchus tshawytscha in the upper Willamette River, Oregon, U.S.A., was analysed to determine if variation in body shape is correlated with migratory life-history tactics followed by juveniles. Body shape was compared between migrating juveniles that expressed different life-history tactics, i.e. autumn migrants and yearling smolts, and among parr ...
