Oregon Shellfish in an Acidified Ocean
Changes to the global atmosphere result in regional shifts in Oregon’s nearshore ocean conditions. As ocean waters throughout the Pacific Basin become more acidified, the biogeochemistry of marine waters also changes along the thin ribbon of the Oregon coast and in bays and estuaries. These open coast and estuarine areas are inhabited by diverse communities of shellfish, including oysters, clams, mussels, abalone, crab, shrimp, sea stars sea urchins, and many others. The presentation will describe ocean acidification as an emerging threat to marine communities, provide a description of the potential impacts to commercially and recreationally valuable groups of shellfish, and characterize the capacity of living shorelines such as kelp beds and eelgrass to serve as a buffer to acidified marine waters.

Ecological Aspects of Transient Killer Whales off the California and Oregon Coast Transient killer whales are important apex predators in marine ecosystems along the Pacific coast. Insights into the latest findings regarding ecology, abundance, distribution, and community structure of these whales along the outer coast and offshore waters of Oregon and California will be presented..
Presenter: Josh McInnes, marine ecologist and marine mammal researcher

Oregon’s Red Abalone
Oregon’s red abalone (Haliotis rufescens) have been the target of a recreational trophy fishery since the 1950s, but following a perfect storm of negative environmental conditions, the fishery was closed in 2018 due to population concerns. Acquiring new information about red abalone biology and habitat, history of the fishery in Oregon and genetic information, allows researchers and managers to work towards a conservation and fishery management plan. ODFW and Oregon Sea Grant have partnered to collaborate with university researchers, agency staff, and fishery participants to determine a framework for an environmentally conscious conservation and management plan for red abalone in Oregon.

Early Period of Occupation at the Tahkenitch Landing Site & Surrounding Area
Molly Kirkpatrick, Archaeologist with the Siuslaw National Forest, will discuss previous archaeological research and the results of recent geoarchaeological investigations at the Tahkenitch Landing Site. This will include a general overview of landscape evolution along the Central Oregon Coast since the last ice-age and its influence on the preservation and distribution of archaeological sites along the coastal front.

Winners and losers: climate and Pacific salmon in coastal Oregon
For species like Pacific salmonids who use habitats from mountains to sea, we would expect different effects from future climate. What we don’t know, is whether our native species have enough adaptive resilience to survive the potentially confounding effects of a changing climate across these varied environments. In this talk, Dr. Flitcroft will discuss the development and adaptation of Pacific salmon to Northwest stream environments, and some of the changes we may expect to see in the future.

Variability in recovery of sea star populations following wasting disease along the Oregon coast and beyond
Beginning in 2013, a disease epidemic termed “sea star wasting” (SSW) caused massive declines within sea star populations ranging from southcentral Alaska to southern California. While SSW persists at low levels in most regions, ochre star populations are trending towards recovery in many areas, including Oregon. However, patterns of recovery vary substantially at both local and broad-scales. Thus, continued monitoring will be essential for documenting the lasting impacts of SSW on this important keystone predator.

Kelp to whales: evidence for a bottom-up trophic cascade
Kelp forests are dynamic ecosystems that provide crucial habitat for a myriad of species across all trophic levels of coastal food webs, including gray whales on the Oregon coast. Gray whales forage heavily in kelp-dominated reefs where high abundances of their zooplankton prey are found. However, kelp forests have been declining along the US West Coast coincident with increases in purple sea urchin populations. Are these changes happening on the Oregon coast and are higher trophic levels, like gray whales, affected? Come hear about the research that a team of Oregon State University researchers to answer these questions.

A Deeper Understanding of Oregon’s Marine Reserves
Join us as we get familiar with Oregon’s five marine reserve sites, look underwater at the Cape Perpetua Marine Reserve, and see what we’ve learned from studying the human dimensions of the marine reserve sites and the Oregon coast.
Presenter: Cristen Don, Marine Reserves Program Leader, Oregon Department of Fish and Wildlife
Registration: https://capeperpetuacollaborative.org/event/deeper-understanding-oregon- marine-reserves/About Cape Perpetua Collaborative: Cape Perpetua exemplifies a unique place where land and sea intersect to produce productive coastal rainforests and ocean upwelling that fuels a productive food web. Working collaboratively and coordinating conservation efforts in this region will help make efficient use to leverage available resources and accelerate the pace at which Oregonians are made aware of, appreciate, understand and support the natural and cultural values of this region.
- Located on the central coast of Oregon, the Cape Perpetua area includes the Cape Perpetua Marine Reserve and Marine Protected Area, numerous state parks, Audubon’s Ten Mile Creek Sanctuary, US Forest Service areas (including the Siuslaw National Forest, Cape Perpetua Scenic Area, and the Rock Creek and Cummins Creek Wilderness Areas), a Globally Significant Important Bird Area for the ESA listed Marbled Murrelet, the Oregon Islands National Wildlife Refuge, Oregon’s Ocean Shore State Recreation Area, and numerous other sites and natural and cultural resources that provide habitats for migratory and resident seabirds, marine mammals, and native fish and wildlife as well as places for people to recreate.
