Characterizing Hydrologic Variability of the Cosumnes River Floodplain

Natural riverine and floodplain ecosystems are adapted to highly variable hydrologic regimes, which include periodic droughts, infrequent large floods, and relatively frequent periods of inundation. To more effectively manage water resources and maintain ecosystem services provided by rivers and...

Priming the productivity pump: flood pulse driven trends in suspended algal biomass distribution across a restored floodplain

1. Chlorophyll a (Chl a) distribution across a 0.36 km2 restored floodplain (Cosumnes River, California) was analysed throughout the winter and spring flood season from January to June 2005. In addition, high temporal-resolution Chl a measurements were made in situ...

Perennial Pepperweed Infestation on the Cosumnes River Experimental Floodplain A Report to the California Bay-Delta Authority

Riparian floodplains present a unique challenge for restoration management, in that these are, by definition, dynamic, constantly changing ecosystems. As restoration projects are initiated and progress through time, both native and invasive species can become established. During the initial...

Invasion in a Diversity Hotspot: Exotic Cover and Native Richness in the Californian Serpentine Flora

Exotic species have been observed to be more prevalent in sites where the richness of native species is highest, possibly reflecting variation among sites in resources, propagule supply, heterogeneity, or disturbance. However, such a pattern leaves unclear whether natives at species-rich sites...

CalJep: A Spatial Distribution Database of CalFlora and Jepson Plant Species

CalJep is a spatially enabled database that reconciles or cross-walks the two prominent electronic plant distribution lists for California: CalFlora and Jepson. We intersected the distribution information from the two data sources to create a refined spatial distribution repository that can be...

Current and Potential Riparian Forest Conditions Along Scott River Watershed Tributaries

In February 2005, members of the Scott River TMDL technical advisory group met in Ft. Jones, California, to review a number of elements of the ongoing work performed by the North Coast Regional Water Quality Control Board, including their affiliates. The TAG members had the opportunity to review...

Fish invasions in California watersheds: testing hypotheses using landscape patterns

An important goal of invasion biology is to identify physical and environmental characteristics that may make a region particularly receptive to invasions. The inland waters of California (USA) are highly invaded, particularly by fishes, although there is wide variation in numbers of nonnative...

Managing Water Temperature TMDLs Under Economic and Environmental Uncertainty

This paper presents an empirical model for analyzing the economics of information acquisition and adaptive watershed management. An empirical application drawn from the Total Maximum Daily Load standard implemented to control in-stream water temperature pollution for the Navarro River watershed...

Nonpoint Source Pollution Modeling in the North Coast of California

The Navarro River watershed hosts one of the last extant populations of coho salmon (Oncorhynchus kisutch) in the Central California Evolutionarily Significant Unit. As such, the identification and restoration of riparian habitats in the Navarro River watershed is paramount to the continued...

Hydrolapse Videography: A Coupled Hydroinformatic Stack For Improved Visual Assessment Of River Dynamics

A central problem for managers of river ecosystems is understanding hydrodynamics in an intelligible fashion for effective decision-making. Too often decisions are based on some combination of incomplete hydrologic time series, poorly parameterized models, photographic snapshots of the place in...
