Wetland plants of the Yellowknife Study Area, 1961-1962

The Yellowknife Study Area (YSA),Northwest Territories, Canada, was established in 1961 by H. W. Murdy, U.S. Fish and Wildlife Service, for the study of wetland and waterfowl ecology. The study area is located on the western edge of the Precambrian Shield and edge of the taiga and is recognized for its high wetland densities and waterfowl abundance. The region is underlain by discontinuous, warm permafrost and hence vulnerable to a warming climate. The completion of Highway 3 in early 1960s provided the first access to the region for development, research, and monitoring. The YSA is a 38-square km area centered on Highway 3, extending 48 km in length. In the 1960s, it encompassed 262 natural ponds and 313 man-made ponds created by highway construction, and portions of the original 1960s highway surface were removed. 
Within the first 6 years following highway construction in 1961, Murdy collected extensive data on the YSA’s wetlands and waterfowl. In 1961-1962 he recorded wetland plant species occurring in each of the 236 ponds and categorized their abundance.  Murdy died before he was able to analyze or publish the wetland data. The original data and aerial photographs are archived at the U.S. Geological Survey, Northern Prairie Wildlife Research Center. The unpublished wetland data described here provide a unique opportunity to investigate long-term changes in wetland plant communities and effects of road building. Related are three datasets describing other aspects of the YSA ponds (see Northern Prairie Wildlife Research Center, 2017, Wetlands of the Yellowknife Study Area, 1963-1965: Characteristics. U.S. Geological Survey data release, https:/dx.doi.org/10.5066/P9YXSNW5). Other data in archived files but not entered or digitally archived include depth to permafrost, selected upland plant communities, weather data, and phenology of plants and waterfowl, among other information.

Forest Management and Cervid Herbivory Data from Western Oregon, USA, 2012 (Seedling Data)

Land management practices often directly alter vegetation structure and composition, but the degree to which ecological processes such as herbivory interact with management to influence biodiversity is less well understood. We hypothesized that intensive forest management and large herbivores have compounding effects on early-seral plant communities and plantation establishment (i.e., tree survival and growth), and the degree of such effects is dependent on the intensity of management practices. We established 225 m2 wild ungulate (deer and elk) exclosures nested within a manipulated gradient of management intensity (no-spray Control, Light herbicide, Moderate herbicide and Intensive herbicide treatments), replicated at the scale of whole harvest units (10-19 ha). Herbivory and herbicide applications interacted to drive vegetation structure, composition and crop-tree establishment, with herbivory effects most evident at intermediate herbicide treatments. Control stands were too forage-rich and Intensive stands too forage-poor to be substantially affected by herbivory. However, with Moderate herbicide treatment – which approximates treatments applied to &gt; 2.5 million hectares in Pacific Northwest U.S.A. – foraging by deer and elk exacerbated the effect of the herbicides, resulting in simplified, low-cover plant communities resembling the Intensive herbicide treatment. In the Light herbicide treatment, herbivory suppressed shrub growth following herbicide treatment, improving planted conifer seedling survival, likely via competitive release from shrubs. Minor reductions in management intensity from the Moderate to Light herbicide treatments therefore facilitated the capacity of wild ungulates to benefit seedling survival – which constitutes early evidence of an ecosystem service. However, this ‘service’ may be to the detriment of native early-seral plant communities. These results demonstrate that by changing community composition and vegetation structure, intensive forest management alters foraging selectivity and subsequent plant-herbivore interactions; such shifts in early-seral communities are likely to influence understory plant communities and tree growth in later stages of forest development.

Backscatter B [7125]--Offshore Half Moon Bay, California

This part of DS 781 presents data for the acoustic-backscatter map of the Offshore of Half Moon Bay map area, California. Backscatter data are provided as two separate grids depending on mapping system (Reson 7125 and Reson 8101). The raster data file is included in "BackscatterB_7125_OffshoreHalfMoonBay.zip," which is accessible from https://pubs.usgs.gov/ds/781/OffshoreHalfMoonBay/data_catalog_OffshoreHalfMoonBay.html. These data accompany the pamphlet and map sheets of Cochrane, G.R., Dartnell, P., Greene, H.G., Johnson, S.Y., Golden, N.E., Hartwell, S.R., Dieter, B.E., Manson, M.W., Sliter, R.W., Ross, S.L., Watt, J.T., Endris, C.A., Kvitek, R.G., Phillips, E.L., Erdey, M.D., Chin, J.L., and Bretz, C.K.

The acoustic-backscatter map of the Offshore of Half Moon Bay, California, map area was generated from backscatter data collected by Fugro Pelagos and by California State University, Monterey Bay (CSUMB). Mapping was completed in 2006 and 2007, using a combination of 400-kHz Reson 7125 and 244-kHz Reson 8101 multibeam echosounders. Within the final imagery, brighter tones indicate higher backscatter intensity, and darker tones indicate lower backscatter intensity. The intensity represents a complex interaction between the acoustic pulse and the seafloor, as well as characteristics within the shallow subsurface, providing a general indication of seafloor texture and composition. Backscatter intensity depends on the acoustic source level; the frequency used to image the seafloor; the grazing angle; the composition and character of the seafloor, including grain size, water content, bulk density, and seafloor roughness; and some biological cover. Harder and rougher bottom types such as rocky outcrops or coarse sediment typically return stronger intensities (high backscatter, lighter tones), whereas softer bottom types such as fine sediment return weaker intensities (low backscatter, darker tones).
