Beaver Moderated Fire Resistance In The North Cascades, Wa, Usa, Joseph Weirich, Rebecca Brown Phd.
Beaver Moderated Fire Resistance In The North Cascades, Wa, Usa, Joseph Weirich, Rebecca Brown Phd.
2020 Symposium Posters
Climate change and fire suppression have altered historic fire regimes creating conditions for larger, high severity fires. Intense burns denude vegetation, alter hydrology, and cause channel incision, impairing riparian function. Burn severity varies based on topography and increases with distance from water sources like lakes, streams, and wetlands. Beaver introduction is a passive technique to restore incised and degraded streams using their unique abilities to build dams, store water and create wetland environments. The objective of this study was to assess whether beaver impoundments increase landscape resistance to wildfire by increasing riparian soil and vegetation moisture levels. We hypothesize that …
Impacts Of Fog Drip On Survivorship And Growth Of Native Herb And Shrub Seedlings On Santa Rosa Island, Julianne Bradbury, Ken Niessen, Kathryn Mceachern
Impacts Of Fog Drip On Survivorship And Growth Of Native Herb And Shrub Seedlings On Santa Rosa Island, Julianne Bradbury, Ken Niessen, Kathryn Mceachern
STAR Program Research Presentations
Overgrazing on Santa Rosa Island led to loss of topsoil in ridgeline groves of endemic island oaks (Quercus tomentella). Restoration specialists attempting to mitigate the impacts of wind and water erosion must determine efficient methods of reestablishing native vegetation. Planting pillows, burlap sacks filled with planting mix and attached to the bedrock substrate, may nurture seedlings long enough for their roots to penetrate the underlying sandstone. Since the island’s ridgeline habitat is often inaccessible during the rainy season, restoration efforts are largely confined to the dry summer months, during which condensed fog is an important source of moisture …
Sediment Loss Of Santa Rosa Island Slopes: An Erosional Study, Michael Perez
Sediment Loss Of Santa Rosa Island Slopes: An Erosional Study, Michael Perez
STAR Program Research Presentations
Ranching began on Santa Rosa Island in the 1840’s, consequently introducing nonnative megafauna that put novel selective grazing pressures on endemic plant species. Their movement patterns also altered sediment integrity as the land was denuded of any stabilizing vegetation. Dense groves of island oak (Q. tomentella) are known to aid in sediment deposition and retention. The groves also function to collect water during periods of intense fog that are common to the island. This experiment sought to quantify the volume of sediment that has been lost on a south facing slope in the middle of the island that …

Recent genetic analysis has shown that the extinct Caspian Tiger (P. t. virgata) and the living Amur Tigers (P. t. altaica) of the Russian Far East are actually taxonomically synonymous and that Caspian and Amur groups historically formed a single population, only becoming separated within the last 200 years by human agency. A major conservation implication of this finding is that tigers of Amur stock might be reintroduced, not only back into the Koreas and China as is now proposed, but also through vast areas of Central Asia where the Caspian tiger once lived. However, under the current tiger conservation …
