Composite Burn Index

NOROCK science has developed capabilities for the remote sensing and evaluation of burns. Working with diverse institutions and individuals in fire science and information technology, we advance mutual interests of fire science partners by undertaking relevant research, and by disseminating findings through coordination and technology transfer.

Robert Fire Montana Tailed Frog Data_2001-2015

The data represent counts of Rocky Mountain Tailed Frog larvae from 8 streams in Glacier National Park, Montana. Each stream was surveyed during 5 different years. We originally sampled the eight streams during June 2001 to evaluate a time-constrained method for potential inclusion in a monitoring program. We sampled streams by turning rocks and disturbing the substrate in front of D-frame...

Predicted daily elk distribution in southern GYE 2010, 2012, 2014

Using data from 288 adult and yearling female elk that were captured on 22 Wyoming winter supplemental elk feedgrounds and monitored with GPS collars, we fit Step Selection Functions (SSFs) during the spring abortion season and then implemented a master equation approach to translate SSFs into predictions of daily elk distribution for 5 plausible winter weather scenarios (from a heavy snow, to...

2015_Glacier margins derived from 2015 satellite imagery for the named glaciers of Glacier National Park, MT and environs

These polygon features represent digitization of the glacier margins for the 37 named glaciers of Glacier National Park (GNP) and two glaciers on U.S. Forest Service’s Flathead National Forest land, derived from 2015 satellite imagery. The polygons represent only the main body portion of each glacier as it appeared in 2015 satellite imagery. Disconnected patches are not included as...

Quantitative PCR results for detecting Tetracapsuloides bryosalmonae in fish tissue and environmental DNA water samples

A probe-based quantitative real-time PCR assay was developed to detect Tetracapsuloides bryosalmonae, which causes Proliferative Kidney Disease in salmonid fish, in kidney tissue and environmental DNA (eDNA) water samples. We present data that was used to determine assay sensitivity, specificity and to define the limits of detection and quantification.

Conventional PCR results for detecting Tetracapsuloides bryosalmonae in fish tissue and water samples

We developed and validated conventional and quantitative real-time PCR assays for the detection of DNA from the myxozoan parasite Tetracapsuloides bryosalmonae, the causative agent of proliferative kidney disease in fish. Assays were tested on fish tissue and on field-collected water samples to assess diagnostic and environmental DNA capabilities. The specificity, sensitivity, and broad...

1998_Glacier margins derived from 1998 aerial imagery for the named glaciers of Glacier National Park, MT and environs

These polygon features represent digitization of the glacier margins for the 37 named glaciers of Glacier National Park (GNP) and the 2 glaciers along the border of GNP derived from aerial images acquired on September 11, 12, 14, 15, 1998. The polygons represent only the main body portion of the glacier as they appeared in the 1998 imagery. Disconnected patches are not included as this dataset...

Distribution of the Yellowstone Grizzly Bear (2000-2014)

The grizzly bear distribution boundary delineates the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2000-2014. The distribution boundary was generated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the...

Multi-century reconstructions of temperature, precipitation, and runoff efficiency for the Upper Colorado River Basin

With increasing concerns about the impact of warming temperatures on water resources, more attention is being paid the relationship between runoff and precipitation, or runoff efficiency. Temperature is a key influence on Colorado River runoff efficiency, and warming temperatures are projected to reduce runoff efficiency. Here, we investigate the nature of runoff efficiency in the upper...

Randomized shortest paths for Grizzly Bear dispersal between the GYE and NCDE

The Randomized Shortest Path (RSP) raster delineates potential dispersal paths for male-mediated gene flow between grizzly bear (Ursus arctos) populations in the Greater Yellowstone Ecosystem (GYE) and the Northern Continental Divide Ecosystem (NCDE). A RSP algorithm was used to estimate the average number of net passages for all grid cells at a spatial resolution of 300 m in the study region...
