Fish activity and movement information derived from acoustic monitoring of a restored Lake Erie coastal wetland from 2011-2014

These data describe estimates of large-bodied fish activity and their direction of movement with respect to a restored wetland located in Ottawa National Wildlife Refuge, Oak Harbor, Ohio, USA.  Acoustic sonar technology was used to monitor fish activity following restoration and reconnection of a hydrologically isolated wetland pool to the wider Lake Erie system. Fish activity was measured during 56 multi-day observational events spanning four years following reconnection (2011-2014). Each hour of acoustic data was processed as an observational unit using a combination of commercial and purpose-built software. The resulting dataset quantifies fish activity and characterizes this movement as immigration into or emigration out of the restored area for 2,022 hours of observation.

Invasive Cyprinid fishes auditory evoked potentials and behavioral thresholds in a lab

This data set contains auditory evoked potentials for four species of invasive carp; silver carp, black carp, grass carp, bighead carp, as well as goldfish (100-150 millimeters in total length) and behavioral thresholds on goldfish in a tank (dimensions 240 centimeters X 100 centimeters; depth of 25 centimeters) at the Columbia Environmental Research Center, Columbia, MO USA.  Ambient sound and experimental tones were recorded using a hydrophone (STD 300; Ocean Instruments, Auckland, NZ) located where fish were placed in the experimental setup. Auditory evoked potentials were collected using a signal processor and bioamplifier (RZ6 and 4Z, Tucker-Davis Technology, Florida, USA) and recorded using the BioSigRZ software (Tucker-Davis Technology, Florida, USA). The stimulus was 100 ms tone bursts at 300, 500, 800, 1000, and 1500 Hz with a cosine-squared gate and 10 ms rise and fall time. Behavioral thresholds were collected for goldfish. To determine threshold, tones were presented to a conditioned fish beginning at approximately 30 decibels (dB) re 1 micropascal above the expected threshold. Each time the goldfish showed detection (suppressing respiration), the tone was lowered by 10 dB. When the fish did not respond, the tone level was increased by 5 dB for a final presentation. Water temperature of the tank was collected with a data logger (HOBO data logger, OnSet, Massachusetts, USA).

Pedestrian evacuation time maps, population estimates, and cruise ship passenger estimates for USVI tsunami-hazard zones

These datasets support the conclusions in the journal article entitled " Population vulnerability of residents, employees, and cruise-ship passengers to tsunami hazards in complex seismic regions: a case study of the U.S. Virgin Islands" as described in the abstract below:
Reducing the potential for loss of life from tsunamis is challenging on islands located in complex seismic regions given the multiple sources that surround islands, differences among islands in the amount of time to evacuate before wave arrival, and the high number of residents, employees, and tourists in tsunami-hazard zones. We examine variations in population vulnerability in island communities to multiple tsunami threats and use the United States territory of the U.S. Virgin Islands (USVI), including St. Thomas, St. John, and St. Croix islands, as our case study. We estimate the tsunami-hazard exposure of residents, employees, and cruise-ship passengers on vessels docking at USVI marine facilities, as well as model pedestrian travel times out of inundation zones for 13 credible tsunami scenarios. Results indicate that the threat to life safety in USVI posed by tsunamis is not equal among the three islands, both in terms of the magnitude of people in hazard zones and the amount of time available to evacuate for the various scenarios. The number of employees and cruise-ship passengers in tsunami-hazard zones is orders of magnitude higher than the number of residents, suggesting that risk assessments that only account for residents are under-estimating threats to life safety from tsunamis. Finally, reducing departure delays has a greater impact than increasing pedestrian travel speeds on reducing the number of people that may have insufficient time to evacuate hazard zones before wave arrival.

Arizona Pronghorn Anderson Mesa Migration Corridors

Pronghorn in the Anderson Mesa herd reside in Game Management Units 5A and 5B, located southeast of Flagstaff, Arizona. The herd summers at higher elevations (7,326 ft [2,233 m]) on Anderson Mesa and winters at lower elevations (5,577 ft [1,700 m]) in Dog Valley. Summer and winter habitats consist primarily of perennial grasslands and shrubs. The steep mesa, as well as impermeable fencing and pinyon and juniper encroachment, limits pronghorn movement between seasonal ranges. These barriers force the Anderson Mesa herd to follow three distinct migration routes separated by Anderson Canyon, Canyon Diablo, and Jacks Canyon. 
Approximately 2.50 miles (4.02 km) north of the herd’s winter range, Interstate 40 creates a barrier to any substantial northward movement by the Anderson Mesa pronghorn. In 1967, high snow levels pushed the Anderson Mesa herd to the Interstate 40 boundary (State Route 66 at the time). The herd’s aversion to barriers and limited access to winter forage caused approximately 77 percent of the herd to die that winter. The Anderson Mesa pronghorn herd continues to recover from the large mortality event, which suggests the importance of maintaining migration corridors for the herd’s seasonal movements.
These mapping layers show the location of the migration corridors for pronghorn (Antilocapra americana) in the Anderson Mesa population in Arizona. They were developed from 30 migration sequences collected from a sample size of 14 animals comprising GPS locations collected every 8 hours.

Arizona Elk State Route 260 Winter Ranges

The State Route 260 elk herd resides east of Payson, Arizona, along State Route 260 in Game Management Units 3C, 4A, 4B, 5A, 22, and 23. The herd winters in a concentrated range around State Route 260 near Kohls Ranch, south of Diamond Rim, and extending to Christopher Mountain and Bearhide Canyon. Most elk summer on the Mogollon Rim (hereafter, Rim), a rugged escarpment at the southern tip of the Colorado Plateau, and descend from the Rim in two primary locations, Sharp Creek and Al Fulton Point, to reach the winter range. Other individuals summer below the Rim, but as winter approaches, they migrate south to the winter range. 
In 2021, the Average Annual Daily Traffic (AADT) on State Route 260 near the herd’s winter range was 6,557 vehicles. Previous studies suggest that when the AADT exceeds 10,000–15,000 vehicles, elk rarely attempt to cross highways unless a designated crossing, such as an underpass, has been established. As development in Arizona continues to expand, it will become increasingly important to effectively manage traffic and accommodate wildlife crossings along State Route 260.
These mapping layers show the location of the winter ranges for elk (Cervus canadensis) in the SR260 population in Arizona. They were developed from 60 sequences collected from a sample size of 41 animals comprising GPS locations collected every 1-4 hours.

Channel centerline for the Nehalem River, Oregon in 1939

The Tillamook Bay subbasins and Nehalem River basins encompass 1,369 and 2,207 respective square 
kilometers of northwestern Oregon and drain to the Pacific Ocean. The Tillamook, Trask, Wilson, Kilchis, 
and Miami Rivers flow into Tillamook Bay near the towns of Tillamook and Garibaldi. The Wilson and 
Trask River basins cover the largest areas (500 and 451 square kilometers, respectively) whereas the 
Tillamook and Kilchis Rivers encompass similar sized areas (156 and 169 square kilometers, respectively) 
and the Miami River the smallest area (94 square kilometers). In cooperation with the U.S. Army Corps 
of Engineers, the U.S. Geological Survey completed a reconnaissance-level assessment of channel 
condition and bed-material transport relevant to the permitting of in-stream gravel extraction along the 
major alluvial portions of six river systems, including the lowermost 14.1 km of the Tillamook River, 
16.3 km of the Trask River, 15.2 km of the Wilson River, 7.8 km of the Kilchis River, 11.6 km of the 
Miami River, and 31.4 km of the Nehalem River. To support these analyses, digital channel maps 
were produced to depict channel and floodplain conditions in the Tillamook Bay sub-basins and 
Nehalem River basin from different time periods. GIS layers defining the wetted channel and bar 
features and channel centerline in the study area were developed for four time periods: 1939, 1967, 
2005, and 2009. For this project, the active channel was defined as area typically inundated during 
annual high flows, and includes the low-flow channel as well as side channels, islands, and channel-
flanking gravel bars. The wetted channel and bar feature datasets were developed by digitizing from 
aerial photographs. Aerial photographs from 1939 and 1967 were scanned, rectified, and mosaicked 
for this project (See metadata for each photograph set for more information on the rectification process 
and resolution of each dataset). Digital orthophotographs from 2005 and 2009 are publicly available.

LANDFIRE 2023 Anderson Fire Behavior Fuel Model (FBFM13) HI

LANDFIRE's 2023 Update (LF 2023) 13 Anderson Fire Behavior Fuel Models (FBFM13) product represents distinct distributions of fuel loadings found among surface fuel components (live and dead), size classes, and fuel types (Anderson 1982). The fuel models are described by the most common fire carrying fuel type (grass, brush, timber, or slash), loading and surface area-to-volume ratio by size class and component, fuel bed depth, and moisture of extinction. LF FBFM13 can be used for fire spread related characteristic models. To create the FBFM13 product, expert rulesets were developed to understand how different types of disturbance would change pre-disturbance fuel models to post disturbance fuels, based on the severity and time since disturbance. These rulesets are represented in the LF Total Fuel Change (LFTFC) Tool and Database. In LF 2023, non-disturbed fuels are the same as LF 2016 Remap for natural vegetation. 
To designate disturbed areas where FBFM13 is modified, the aggregated Annual Disturbance products from 2014 to 2023 in the LF Fuel Disturbance (FDist) product are used. All existing disturbances between 2014-2023 are represented in LF 2023, and the products are intended to be used in 2024 (the year of release).  
When using any product from the LF 2023 fuel product suite, users should consider adjusting fuel layers for disturbances that occurred after the end of the 2023 fiscal year (after October 1st, 2023). Disturbances that occurred after the end of the 2023 fiscal year are not accounted for within LF 2023 fuel products. Learn more about LF 2023 at https://landfire.gov/data/lf2023.

LANDFIRE 2023 Fuel Vegetation Type (FVT) HI

LANDFIRE's 2023 Update (LF 2023) Fuel Vegetation Type (FVT) product represents the LF Existing Vegetation Type Ecological Systems (EVT) product modified to represent pre-disturbance EVT in areas where disturbances have occurred over the past 10 years. In LF 2023, vegetation products are created through an image-based process (within the Conterminous United States (CONUS)) that assesses canopy structure (Forest Canopy Height (CH) and Cover (CC)). Due to shifting EVT codes and labels throughout the years, the FVT codes are based on an early version of EVT codes translated from the current version. FVT is an input for fuel transitions related to disturbance and fuel products in LF 2023 were created with LF 2016 Remap vegetation in non-disturbed areas. 
To designate disturbed areas where FVT is modified, the aggregated Annual Disturbance products from 2014 to 2023 in the LF Fuel Disturbance (FDist) product are used. All existing disturbances between 2014-2023 are represented in LF 2023, and the products are intended to be used in 2024 (the year of release).
