Non-Native Invasive Aquatic Plant And Mussel Survey Of Six Umpqua National Forest Area Lakes, Mark Sytsma, Rich Miller, Rupa Shrestha

Six lakes and ponds located within or near the Umpqua National Forest were surveyed for non-native aquatic plants and mussels during August, 2009. A diverse assemblage of native plants was identified along with one possible non-native aquatic plant hybrid in Herberts Pond. The possible hybrid between the non-native species Myriophyllum spicatum and the native species M. sibiricum requires genetic analysis for identification. Water chemistry is suitable for the establishment of invasive mussels in Buckeye Lake; however, no zebra or quagga mussel veligers were detected in any of the lakes.

This Alaska Spartina Prevention and Response Plan reviews the known impacts, biology, and invasion history of Spartina on the west coast. It outlines strategies for prevention, early detection and efficient organization of rapid response efforts following the confirmation of an infestation. The goal of the plan is to prevent the establishment of any Spartina populations and to eradicate established infestations if detected within the State’s estuaries or coastal wetlands. Five objectives and strategies are described and 31 specific tasks are outlined to achieve this goal. These include: • Prevention of establishment through vector and source population control. • Plan coordination …

Climate change will affect various sectors of water resources in Oregon in the 21st century. The observed trends in streamflow show significant declines in September flow and, although not significant, increases in March flow in many transient rain-snow basins. These streamflow trends are associated with rising temperature and coincident declines in snowpack in spring in the latter half of the 20th century. While there are no distinct trends in high precipitation events, such events are associated with climate variability such as ENSO and PDO. Effects of ENSO and PDO are more pronounced at the beginning and end of the wet …
