“…In the southwestern United States, the salt cedar significantly degrades native riparian ecosystems through soil salinization and narrowing of river channels, resulting in displacement of native vegetation and a decrease in biodiversity (Zavaleta 2000). However, the salt cedar also provides critical nesting habitat for the flycatcher (Hatten andParadzick 2003, Owen et al 2005) because much of the native cottonwood (Populus spp.) and willow (Salix spp.)…”

“…In many real-world situations, this lack of consistency results in little disparity between ecosystem restoration and endangered species management. However, notable controversies have occurred across a wide variety of taxa and environments, particularly when endangered species use non-native invasive species for food or shelter or when restoration actions harm a species or its habitat, e.g., the Kanab ambersnail (Oxyloma haydeni kanabensis; Stevens et al 2001), the Southwestern Willow Flycatcher (Empidonax traillii extimus; Hatten andParadzick 2003, Owen et al 2005), the tidewater goby (Eucyclogobius newberryi; King et al 2006), and the Mexican Spotted Owl (Strix occidentralis lucida; Prather et al 2008). The phenomenon of endangered species facilitation by non-native species presents a management challenge that results in a conflict between the goals of ecosystem restoration and species preservation (e.g., U.S. Wildlife Service 1997, Van Riel et al 2000).…”

ABSTRACT. Management actions to protect endangered species and conserve ecosystem function may not always be in precise alignment. Efforts to recover the California Ridgway's Rail (Rallus obsoletus obsoletus; hereafter, California rail), a federally and statelisted species, and restoration of tidal marsh ecosystems in the San Francisco Bay estuary provide a prime example of habitat restoration that has conflicted with species conservation. On the brink of extinction from habitat loss and degradation, and non-native predators in the 1990s, California rail populations responded positively to introduction of a non-native plant, Atlantic cordgrass (Spartina alterniflora). California rail populations were in substantial decline when the non-native Spartina was initially introduced as part of efforts to recover tidal marshes. Subsequent hybridization with the native Pacific cordgrass (Spartina foliosa) boosted California rail populations by providing greater cover and increased habitat area. The hybrid cordgrass (S. alterniflora × S. foliosa) readily invaded tidal mudflats and channels, and both crowded out native tidal marsh plants and increased sediment accretion in the marsh plain. This resulted in modification of tidal marsh geomorphology, hydrology, productivity, and species composition. Our results show that denser California rail populations occur in invasive Spartina than in native Spartina in San Francisco Bay. Herbicide treatment between 2005 and 2012 removed invasive Spartina from open intertidal mud and preserved foraging habitat for shorebirds. However, removal of invasive Spartina caused substantial decreases in California rail populations. Unknown facets of California rail ecology, undesirable interim stages of tidal marsh restoration, and competing management objectives among stakeholders resulted in management planning for endangered species or ecosystem restoration that favored one goal over the other. We have examined this perceived conflict and propose strategies for moderating harmful effects of restoration while meeting the needs of both endangered species and the imperiled native marsh ecosystem.

“…The satellite model uses a logistic regression equation to divide riparian vegetation into a continuous range of probabilities extending from almost 0 to 99 percent, with higher probabilities most likely to contain a flycatcher territory. The model has been successfully tested at Alamo Lake, Arizona (Hatten and Paradzick, 2003); applied statewide in Arizona with 2001 imagery (Dockens and others, 2004); and projected along the Rio Grande River, New Mexico . In each case, the satellite model performed within expectations by identifying riparian areas with the highest densities of flycatcher territories.…”

“…The Arizona Game and Fish Department developed a flycatcher remote sensing/geographic information system (GIS) habitat model (hereinafter referred to as the "satellite model") that uses Landsat Thematic Mapper imagery and a 30-m-resolution digital elevation model (Hatten and Paradzick, 2003). The satellite model was developed with presence/absence survey data acquired along the San Pedro and Gila Rivers, and from Salt River and Tonto Creek inlets to Roosevelt Lake in southern Arizona.…”

Remote sensing has established a key role in modern wildlife ecology, but the data types and methods are both varied and complex, and the potential for misuse by the uninformed is high. The basic attributes of earth-observing sensors and data products can be described by their spectral, spatial, radiometric, and temporal resolutions, and general categories of data products are normally consistent across agencies and organizations. Users of remote sensing technology seeking to link information needs with remote sensing strategy must balance knowledge of data and processing techniques with a clear understanding of the nature of the information desired. Wielded within a sophisticated application framework, remote sensing allows for an impressive suite of wildlife ecology and habitat attributes to be modeled, predicted, and monitored through time, including land cover physiognomy, vegetation structure and condition, forage characteristics, specific nutrient concentrations, overall productivity, and biomass. IntroductionA spatial information management approach to applied wildlife ecology will rely on our capacity to link animal-based data sets -observations related to a species' distribution, abundance, health, or genetics, for example -to a variety of spatially
