With the broad range of plants susceptible to Phytophthora and other plant pathogens, there is the potential in restoration activities to inadvertently introduce Phytophthora-infected nursery stock into sensitive habitats, setting up a direct pathway for pathogen introduction and spread, and destroying the ecological values that restoration is trying to enhance.

In 2011, efforts for a large-scale habitat enhancement project in this section of the Little Truckee River began, first with characterization of the system’s functional impairments, followed by development of a conceptual habitat enhancement design.
Squaw Creek and the montane meadows of Olympic Valley are iconic of Sierra watersheds with prominent visibility as an international tourist destination. As Squaw Creek winds its way down from the Pacific Crest to the Truckee River, three landowners account for about 90% of the watershed’s land base. The protection, restoration, and enhancement of the Squaw Creek watershed warrants participatory collaboration amongst these landowners for the mutual benefit of the resource.
What do you get when you mix Caltrans, an environmental advocacy group, tufa soil (pH8.3), a 60-degree slope, and the need to make sure you can effectively stabilize that slope?
Adaptive management has become popular precisely because it has been recognized and shown that command and control structures are often not applicable to dynamic, complex, and oftentimes chaotic, natural processes. But what is adaptive management and does it work?
Invertebrates can be effective indicators of the consequences of non-native plant invasions due to the important functional roles that they play in ecosystems, including nutrient recycling and energy flow, pollination, seed dispersal, and the maintenance of plant and animal community structure.
As practitioners tasked to plan or evaluate restoration projects and meet permit requirements in freshwater habitats, we often neglect non-listed species. Half of all freshwater species in California are considered to be vulnerable to extinction, and extinction rates in freshwater ecosystems are 4 to 5 times higher than those of terrestrial systems.
SWAMP has developed a variety of tools for use in bioassessment, including indices for interpreting stream health based on biological data, taxonomic resources for identifying BMIs and benthic algae, and standard operating procedures for conducting field sampling and sample processing in the laboratory.

In 2012 the first detection was made of a new plant pathogen, Phytophthora tentaculata (USDA), in a native nursery in California and the potential for restoration nurseries to be direct vectors of pathogens to wildland sites became chillingly clear. Our paradigm as to the “responsible” or “right way” to revegetate is being challenged.
In September 2015, a National Seed Strategy for Rehabilitation and Restoration was introduced by the federal government (BLM) to address the impacts of plant community disturbances by natural and man caused events.
