Would You Like Fires With That? Using Stakeholder-Derived Forest Management Preference Maps To Model Landscape-Level Fuel Reduction Treatment Effects On Wildfire Spread, Brooke A. Cassell, Robert M. Scheller, Max Nielsen-Pincus
Would You Like Fires With That? Using Stakeholder-Derived Forest Management Preference Maps To Model Landscape-Level Fuel Reduction Treatment Effects On Wildfire Spread, Brooke A. Cassell, Robert M. Scheller, Max Nielsen-Pincus
ESM Colloquium
Management of public lands in the U.S. aims to achieve multiple goals relating to ecological function, wildlife habitat, support of local economies, and recreation; and in fire-prone landscapes these goals are often combined with fuels reduction treatments such as forest thinning and prescribed fire. Applied landscape research may attempt to evaluate the tradeoffs implicit in public lands planning or envision potential future land management scenarios, but often fails to incorporate the spatial diversity of stakeholder perspectives. This study explores the use of public participation geographic systems (PPGIS) to identify spatial and thematic community preferences for fuel treatments in a fire-prone …
Non-Native Mangroves Of Moloka’I, Hawai’I: A Socio-Ecological Analysis, Casey Lewis
Non-Native Mangroves Of Moloka’I, Hawai’I: A Socio-Ecological Analysis, Casey Lewis
ESM Colloquium
Invasive species are recognized as a leading threat to biodiversity and their management is expensive, time consuming, and labor intensive. Therefore, it is important to review both benefits and detriments of the species to inform appropriate management decisions. Red mangrove was introduced to Moloka'i, Hawaii in 1902 to mitigate the effects of soil erosion and has since spread along the coast and to adjacent islands creating novel habitat. This study assessed both biological services and social attitudes towards Moloka'i's non-native mangroves to provide a comprehensive evaluation of the species. Zooplankton community structure was examined in mangrove and non-mangrove sites and …
Modeling The Effectiveness Of Riparian Restoration On Stream Shading In The Clackamas River Basin, Rachel Barksdale
Modeling The Effectiveness Of Riparian Restoration On Stream Shading In The Clackamas River Basin, Rachel Barksdale
ESM Colloquium
Rivers and streams within the Clackamas River Basin are not currently meeting water quality standards in terms of temperature. The Clackamas River Basin Council (CRBC) designed a restoration program to address the thermal loading on behalf of Portland General Electric (PGE) in which native trees and shrubs are planted along streams to restore riparian canopy cover. Solar radiation can be blocked by restoring canopy cover and is an effective way to provide shade, as well as providing ancillary environmental benefits such as enhanced wildlife habitat and erosion control. Stream and vegetation data were collected at nine sites to model the …
Effects Of Beaver Dams On Surface Water Flow During Storm Events In An Urban Landscape, Erin Poor
Effects Of Beaver Dams On Surface Water Flow During Storm Events In An Urban Landscape, Erin Poor
ESM Colloquium
Urban land-use generally alters the hydrologic cycle, leading to changes in the natural flow regime of local streams. Runoff from impervious surfaces and routing of stormwater to streams causes urban streams to respond quickly and more intensely to storm events-more so than then would be observed in a less urbanized landscape. The rapid pulse of water that is routed to streams during precipitation events can degrade the physical structure of the channel and alter water quality and habitat availability. To manage these common urban stream issues, agencies have been seeking alternative ways of restoring and enhancing resilience in urban stream …
Long-Term Ecological Research In Forest Park: Tracking Urban Impacts To Forest Structure And Productivity, Andrew Addessi, Marion Dresner
Long-Term Ecological Research In Forest Park: Tracking Urban Impacts To Forest Structure And Productivity, Andrew Addessi, Marion Dresner
ESM Colloquium
Current and historic land use practices as well as exposure to an urban environment can impact forest structure and function. Past and ongoing research in Forest Park, a large urban forest in Portland, Oregon, suggests that mature Douglas-fir (Psuedotsuga meziesii) dominated conifer stands in the more urban end of the park are not developing certain late successional features. Notably, they lack a shade-tolerant conifer understory composed of western hemlock (Tsuga heterophylla) and western red-cedar (Thuja plicata). Here, I present three lines of investigation taken from several 1-hectare permanent long-term ecological research (LTER) plots in Forest Park. First, I investigated whether …
Community Science And The Ecological Merits Of Backyard Habitat Patches And Adjacent Green-Spaces For Urban Avian Species, Kristen S. Gulick, Nikkie West, Marion Dresner
Community Science And The Ecological Merits Of Backyard Habitat Patches And Adjacent Green-Spaces For Urban Avian Species, Kristen S. Gulick, Nikkie West, Marion Dresner
ESM Colloquium
In what ways do small-scale urban backyards contribute to local bird abundance and biodiversity? In what ways might these yards serve as an ‘extension’ of neighboring native forest areas? This project investigates the contribution that a group of backyards, certified through the Backyard Habitat Certification Program, have in the suburb of Hillsdale, Oregon, which is adjacent to the natural area of Keller Woodland. Backyard owners functioning as citizen or community scientists assisted with conducting residential bird point-counts once a week in each backyard and the natural area. Counts were done for a total of 8 weeks during nesting season to …
The Limitation Of Spread Of Non-Native Marine Invertebrates From Artificial Structures To Natural Habitats, Whitney Mcclees, Catherine E. De Rivera
The Limitation Of Spread Of Non-Native Marine Invertebrates From Artificial Structures To Natural Habitats, Whitney Mcclees, Catherine E. De Rivera
ESM Colloquium
Artificial structures created for aquatic anthropogenic activities are often colonized and fouled by many non-native species, few of which have invaded natural areas. Some research has indicated predation is limiting the spread of non-native species, while other research has indicated that it is dispersal-driven. To determine the effects of dispersal limitation and predation on the risk to surrounding habitats of being invaded by non-native species established on marina docks, we used a three-factor design, deploying seven unglazed ceramic panels per each treatment combination of 1) inside versus outside a marina in Yaquina Bay, Oregon; 2) cage keeping out predators >mesh …
Informing Oregon's Marine Protected Area (Mpa) Baseline: Past And Present Tribal Uses Of Marine Resources, Sabra Marie Tallchief Comet
Informing Oregon's Marine Protected Area (Mpa) Baseline: Past And Present Tribal Uses Of Marine Resources, Sabra Marie Tallchief Comet
ESM Colloquium
Native American tribes with ancestral land adjacent to the coast have gathered, hunted, and fished marine resources for millennia. In 2012, the state of Oregon designated five marine sites as reserves in which ocean development and harvest were prohibited. Marine Protected Areas (MPAs) are paired with each of the reserves and have less stringent “take” restrictions. Conflict over tribal use of MPAs have arisen in other states (e.g., California) as designation of MPAs and Reserves can impact subsistence, ceremonial, and traditional uses. My master’s thesis is intended to inform Oregon MPA management by developing a dataset that will describe tribal …
