This dataset was used as part of a continent-wide analysis of tree fecundity and its association with climate and tree size. This dataset consists of: plotinfo.csv, which contains basic attribute information for the field plots where the data were collected; seeddata.csv, which contains the data for seeds collected (how many, what type, etc.); trapxycoord.csv, which contains location and identification information for the seed traps used to collect the seeds; treexycoord.csv, which contains location and attribute information for the standing trees in the plot where the seeds were collected; and treedata.csv, which contains data on the size and species of standing trees in the plot where the seeds were collected.
Provided are data containing condition assessments on individual giant sequoia (Sequoiadendron giganteum; SEGI) stems and post-fire regeneration counts within Board Camp, Suwanee, New Oriole Lake, Homer’s Nose, and a subset of Redwood Mountain and Dillonwood groves of Sequoia and Kings Canyon national parks, respectively. Stem data contain condition-related attributes (e.g., spatial location, diameter breast height, status - live or dead, percent canopy that is live, scorched or torched). Regeneration plots are located using a spatially-balanced sampling design (Generalized Random Tessellation Stratified - 'GRTS'). Each regeneration plot is a fixed radius circle (11.35 meters or 17.84 meters) and contain count data...

This dataset details mercury (Hg) stable isotope values in dragonflies and fish tissues collected across U.S. National Parks. Dragonfly samples were collected as part of the Dragonfly Mercury Project (https://geonarrative.usgs.gov/dmp/), a citizen science project focused on using dragonfly larvae as biosentinels for Hg bioaccumulation. Fish were collected as part of separate park-wide monitoring initiatives. Biological samples were collected from 2014-2019 and composited for Hg stable isotopes measurements by the U.S. Geological Survey Contaminant Ecology Research Laboratory (CERL, Corvallis, Oregon). Measurements for Hg isotopes were performed by the U.S. Geological Survey Mercury Research Laboratory (MRL, Madison,...

These snag (dead tree) fall data were collected as part of long term forest dynamics data. Tree fall data were collected non-systematically as text comments until 2013, after which explicit snag fall data were collected on an annual basis. This particular dataset includes data from 23 plots in old-growth mixed conifer and montane conifer forests in Sequoia-Kings Canyon and Yosemite National Parks. The plots range in size from 0.9 ha to 2.5 ha and were established from 1982 to 2001. We used demography plot data through 2021 (collected before the extensive KNP Complex wildfire burned many of the plots). Before 2021, four of the 23 plots had experienced relatively recent prescribed burns or wildfires. When established,...

These tables include data from 25 long-term forest plots located in either Sequoia or Yosemite national park. Trees in these plots (established between 1982 and 2001) are censused annually for mortality and measured for diameter every 4 to 6 years. Plots were mostly 1 hectare (ha) in size (range 0.9 – 2.5 ha) and contained at least two 25 by 25 meter seedling sub-plots to monitor natural seedling recruitment. The largest plot, at 2.5 ha, included four such seedling sub-plots. Each sub-plot was divided into 5 by 5 meter quadrats. In almost all the plots these seedling sub-plots were established in 1999, but four plots (those with names starting with FF) were added to the study in 2002 and seedling data was only available...

Sequoia National Park, California. Snow chutes on the north side of Mount Hitchcock. 1935.
Sequoia National Park, California. Glacial cirque in massive, exfoliating granite southwest of Hamilton Lake. 1936.
Sequoia National Park, California. Mount Stanford, Mount Ericson, and Harrison Pass. 1935.
Sequoia National Park, California. A more perfect example of an Indian pit than photo mfe00680. The litter cleaned out of it contained a thin layer of rhyolitic ash and some charcoal near the bottom. 1925.
Sequoia National Park, California. Up East Lake with Mount Brewer group spurs on the right and Kings-Kern Divide in the distance. 1925. Photos mfe00743 and mfe00744 form a panorama.
Sequoia National Park, California. North side of Mount Hitchcock, viewed across Whitney Canyon. An unusually fine series of parallel avalanche chutes is shown here. These chutes have been formed across a system of vertical joint fractures in the granite; their positions are not determined by master joints extending parallel to their axes. The chutes all terminate at the upper limit of glacial action, below which the canyon wall is straight, although it is hackled in detail by glacial sculpturing. Circa 1935. Figure 49, U.S. Geological Survey Professional paper 504-A.

Sequoia National Park, California. Glaciated knob at the head of South Fork Kaweah River. This knob was overridden by the earlier glaciers but not by those of the Wisconsin Stage, as is evident from the relative position of the older and younger moraines nearby. During the long period since it was glaciated, the knob weathered into jagged forms. Infiltration of water doubtless has been facilitated by the high angle of the jointed fractures and, as a consequence, disruption by frost has been particularly vigorous. Circa 1935. Figure 28, U.S. Geological Survey Professional paper 504-A.
Sequoia National Park, California. Chagoopa Plateau and Moraine Lake, viewed from the edge of Big Arroyo. The plateau and timbered benches on the far side of Big Arroyo are remnants of an erosion surface left after trenching of the canyon. Circa 1935. Figure 40, U.S. Geological Survey Professional paper 504-A.
Sequoia National Park, California. Junction of Crabtree Canyon (foreground) and Whitney Canyon (background). The sparsely jointed floor of Crabtree Canyon shows the effects of glacial quarrying. The intercanyon ridge in the middle distance has angular hackly forms produced by glacial quarrying in well-jointed granite. The Whitney Glacier spilled over the ridge and quarried its downstream side. The well-jointed canyon slopes in the background also exhibit the effects of glacial quarrying. 1935. Figure 47, U.S. Geological Survey Professional paper 504-A.
