Effects Of Manual And Mechanical Ammophila Arenaria Removal Techniques On Coastal Dune Plant Communities And Dune Morphology, Monique R. Silva Crossman

Cal Poly Humboldt theses and projects

The removal of invasive species as part of the restoration process can allow natives organisms to rebound. An ecosystem that incurs damages from invasive species is coastal sand dunes, which are dynamic systems. Some coastal sand dunes on the west coast of the United States have been invaded by Ammophila arenaria. The invasive grass, A. arenaria, is thought to alter and stabilize foredune morphology and reduce populations of native species. The objectives of my research are to examine the effects that manual and mechanical A. arenaria removal techniques have on coastal sand dune morphology and vegetative cover over time. …

Assessing Spatio-Temporal Patterns Of Forest Decline Across A Diverse Landscape In The Klamath Mountains Using A 28-Year Landsat Time-Series Analysis, Drew S. Bost

Cal Poly Humboldt theses and projects

Rates of tree mortality in California and the Pacific Northwest have greatly increased in recent years, driven largely by pest and pathogen outbreaks as well as the effects of hotter, warmer droughts. While there have been a multitude of regional-scale assessments of mortality and forest decline, landscape-level studies are necessary to better identify forests that are most vulnerable to decline and to anticipate future changes. This need is particularly notable in the remote and little-studied mountains of northwest California, which are renowned for their diverse, heterogeneous vegetation types. A recent observation of elevated levels of Shasta red fir (Abies …

Existing Ecological Conditions And Management Recommendations For A Portion Of The Chehalem Ridge Nature Park, Oregon, Amanda Pole

Environmental Science and Management Professional Master's Project Reports

Effective land management and habitat restoration work rely on the collection of baseline information regarding the existing conditions of the planning area. Existing conditions assessments can include such information as hydrologic conditions, botanical species assessment, land use issues, wildlife surveys, habitat distribution/quality assessments, etc. This project provides Oregon Metro’s Parks and Nature department with updated information regarding the existing conditions of a portion of the Chehalem Ridge Nature Park (CRNP) as well as recommendations and supplemental maps to aid in future management planning.

Within the ~61-acre project area exist several habitat types: a developing seasonal wetland, riparian forest, Douglas-fir forest, …

Climate Change Challenges For Land Conservation: Rethinking Conservation Easements, Strategies, And Tools, W. William Weeks, Jessica Owley, Federico Cheever, Adena R. Rissman, M. Rebecca Shaw, Barton H. Thompson

Articles by Maurer Faculty

Climate change has significant consequences for land conservation. Government agencies and nonprofit land trusts heavily rely on perpetual conservation easements. However, climate change and other dynamic landscape changes raise questions about the effectiveness and adaptability of permanent conservation instruments like conservation easements. Building upon a study of 269 conservation easements and interviews with seventy conservation-easement professionals in six different states, we examine the adaptability of conservation easements to climate change. We outline four potential approaches to enhance conservation outcomes under climate change: (1) shift land-acquisition priorities to account for potential climate-change impacts; (2) consider conservation tools other than perpetual conservation …
