Research & Maps

Friends’ scientific research gives decision makers the information to make sound choices about San Juan County’s growth management.

Shoreline Inventory

Friends and its partners’ scientific research and habitat assessments help inform the region’s decision-makers and government agencies so their growth management decisions can be based on current science.

Friend’s Nearshore Habitat Assessment

Forage Fish Spawning Habitat Survey

Friends leads efforts in San Juan County to map beach spawning forage fish, including surf smelt and Pacific sand lance, and assists with exploratory surveys for pacific herring spawning areas.

Eelgrass Health

Friends and agency partners completed the first countywide mapping of eelgrass. Current projects monitor eelgrass beds in priority bays to assess their location, condition, and impacts from other environmental factors.

Feeder Bluff Mapping

Friends partnered with Coastal Geologic Services to complete a countywide feeder bluff mapping effort and works to protect our valuable feeder bluffs by making them a conservation and restoration priority.

Shoreline Modification

Friends surveyed all 400+ miles of the county’s marine shorelines, cataloging and mapping over 3,500 individual shoreline modifications such as hard bulkheads, docks, and buoys. Used with habitat inventory results, this data helps identify and prioritize shoreline restoration opportunities. With roughly 40% of all shoreline parcels having been modified in some way, our shorelines are in need of protection.

Sea Level Rise Vulnerability

Friends partnered with coastal scientists to develop a countywide evaluation and mapping  of the infrastructure, developments, and habitats that are vulnerable to increased erosion and flooding from rising sea levels. Results are being used by public and private property owners and communities to increase resiliency.
