I am an emerita Biologist at the U.S. Geological Survey. During my career I studied the interaction between large herbivores (elk and mountain goats) and vegetation, and the effects of climate change on subalpine vegetation. I also worked on designing ecological monitoring programs and protocols; and incorporating climate change into natural resource management plans.
As an emerita scientist, I have been finishing up a few projects that were not completed before I retired. These included two papers with co-authors describing long-term data sets: 36 years of research on old-growth forest structure based on data from elk exclosures and 28 years of data on subalpine fir seedling survival, both in Olympic National Park. I also completed with co-authors an implementation guide for decision tools meant to incorporate climate change into management decisions made by the USDA Forest Service. I am currently working on updating a field guide to mosses, lichens, and liverworts of the Pacific Northwest. I remain very interested in the curious distribution of cottonwoods in Olympic National Park and may pursue that a bit more before calling it a career.

Ecosystem structure and processes of coastal temperate rainforests of the Pacific Northwest are thought to be strongly influenced by herbivory primarily of Roosevelt elk (Cervus elaphus roosevelti) and secondarily of Columbian black-tailed deer (Odocoileus hemionus columbianus). Two large (0.5-ha) exclosures were built in old-growth coniferous rainforest communities in Olympic National Park, WashiAuthorsAndrea Woodward, Kurt Jenkins, Mark E HarmonEstablishment and survival of subalpine fir (Abies lasiocarpa) in meadows of Olympic National Park, Washington
Establishment of trees in subalpine meadows is a potential indicator of ecological effects of climate change. Tree establishment is a multi-year process including cone and seed production, germination, establishment, and growth, with each demographic step possibly sensitive to different climate limitations. While most studies have focused on one or a few steps, this study follows a cohort of indivAuthorsAndrea Woodward, Jonathan A.

Rock gnome lichen (Gymnoderma lineare [Evans] Yoshimura and Sharp) was listed as a federally endangered species in 1995. It is endemic to the southern Appalachian Mountains, with most known populations occurring in North Carolina, where it grows on vertical rock faces in the fog zone above an elevation of 1,525 meters or in humid, deep river gorges. Threats to the species include recreational useAuthorsAndrea WoodwardIntegrating climate change considerations into natural resource planning—An implementation guide

Salmon populations spawning in the Lake Ozette watershed of northwestern Washington were once sufficiently abundant to support traditional Tribal fisheries, and were later harvested by settlers. However, in 1974 and 1975, the sockeye salmon (Oncorhynchus nerka) harvest decreased to 0 from a high of more than 17,500 in 1949, thus stimulating research into the causes of decrease, which resulted in eAuthorsAndrea Woodward, Mike Haggerty, Patrick CrainSkagit River coho salmon life history model—Users’ guide
Natural resource management is conducted in the context of multiple anthropogenic stressors and is further challenged owing to changing climate.

The rugged landscapes of northern Idaho and western Montana support biodiverse ecosystems, and provide a variety of natural resources and services for human communities. However, the benefits provided by these ecosystems may be at risk as changing climate magnifies existing stressors and allows new stressors to emerge.

A major challenge in the biological monitoring of stream ecosystems in protected wilderness areas is discerning whether temporal changes in community structure are significantly outside of a reference condition that represents natural or acceptable annual variation in population cycles. Otherwise sites could erroneously be classified as impaired. Long-term datasets are essential for understandingAuthorsAlexander M. Milner, Andrea Woodward, Jerome E. Freilich, Robert W.

Natural Resource Condition Assessments (NRCAs) evaluate current conditions for a subset of natural resources and resource indicators in national parks.

Terrestrial Vegetation Dynamics
Plant communities are the foundation for terrestrial trophic webs and animal habitat, and their structure and species composition are a result of biological and physical drivers. Additionally, they have a major role in geologic, geomorphic and soil development processes. Several global and regional stressors (for example, climate change, atmospheric and precipitation chemistry, introduced pests...Tools and Techniques for Synthesizing Monitoring and Other Data
Determining the best strategy for managing natural resources often requires a synthetic analysis describing the interactions among a multiplicity of ecosystem components and driving factors. However, comprehensive data sets are rarely collected to include all factors relevant to a given management decision. When data are obtained from multiple sources, they are often difficult to synthesize...Frameworks, Strategies, and Protocols for Monitoring and Interdisciplinary Research
Natural resource managers are faced with the prospect of dramatic climate change, the commencement of ecosystem- and landscape-scale restoration and management initiatives, as well as an interest in learning from and being accountable for restoration projects. The consequent needs for information have motivated many agencies to institute ecological monitoring programs and interdisciplinary...Developing Tools for Climate Change Adaptation
Resource managers contend with achieving goals and mandates in an ever-changing world of exotic species invasions, emerging diseases, extinction risks, and shifting public expectations among others. These challenges must be faced in the context of a changing climate, which potentially alters ecosystem structure and function and undermines the predictability of ecosystem response to management... - Data

Riparian Final Vegclass. Olympic National Park NRCA Westside Rivers Riparian Vegetation Project (2016)
Beschta and Ripple (2012) assert that increased elk populations in the Olympic National Park due to extirpation of wolves in the 1920s has led to a reduction in riparian vegetation. They hypothesize that a decrease in this vegetation has led to an increase in erosion and undercutting of large conifer trees along the river banks, causing woody debris in the river, which in turn impacts channel morp - News
