Layer: NMSU_DEVA_Damage_Assessment_Points (4)

Name: NMSU_DEVA_Damage_Assessment_Points

Display Field: roadname

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This point feature class contains road damage assessment data collected by the Student Conservation Association (SCA) Flood Recovery Team during 2024 field operations in Death Valley National Park. The dataset documents point-based road damage features along unpaved roads throughout the park, collected in response to flood events that caused widespread damage to the park's backcountry road network. Point damage types include: Cattle Guard Damaged Driving Surface, Cattle Guard Damaged Gates, Cattle Guard Damaged Wings, Cattle Guard Silted In, Culvert Buried Pipe, Culvert Crushed Pipe, Culvert Full of Debris, Culvert Pipe Exposed, Culvert Pipe Blocked By Vegetation, Graffiti Carving, Graffiti Dirt Drawing, Graffiti Paint, Obstacle Eroded Ledge, Obstacle Hole, Obstacle Rock, Obstacle Other, Pothole Single, Pothole Multiple, Signage Damaged, Signage Missing, and Vegetation Tree Removal. Each record includes the damage type, severity rating (Low, Medium, or High where applicable), depth or height measurements in inches, recommended corrective actions, road name, milepost references, and FMSS asset identifiers. Pothole severity thresholds vary by road classification (2WD Low Clearance, 2WD High Clearance, 4WD High Clearance, and 4WD Rough Road) and consider both width and depth dimensions as defined in the Objective Damage Thresholds document (Version 1.0, January 8, 2024). Point features represent damage less than 2 meters in length along the road centerline; damage 2 meters or longer was collected as lines in a companion dataset (DEVA_GIS_SCA_Road_Damage_Lines). Data was collected using Esri Field Maps paired with Trimble Catalyst DA2 GNSS receivers operating on a Catalyst Premium subscription with real-time RTX (Real-Time Extended) satellite corrections, providing 60cm horizontal accuracy specification. An accuracy threshold of 6 feet (1.83 meters) was enforced; points exceeding this threshold were not accepted. Attachments are enabled on this feature class to store field photographs documenting damage conditions.

Layer: NMSU_Desert_Tortoise_Core_Habitat (5)

Name: NMSU_Desert_Tortoise_Core_Habitat

Display Field: habitat_category

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Core habitat areas for desert tortoise (Gopherus agassizii) in Death Valley National Park. This layer identifies concentrated zones of moderate and optimal habitat quality based on a multi-variable habitat suitability index (HSI) model. Core areas represent locations where suitable habitat is spatially concentrated rather than scattered or fragmented, indicating higher-quality habitat zones for tortoise populations. The layer was derived through focal density analysis of classified habitat suitability rasters, using a 450-meter radius neighborhood (approximately 64 hectares) to identify areas where at least 40% of the surrounding landscape consists of moderate or optimal habitat. This density-based approach distinguishes between core habitat areas (concentrated suitable conditions) and edge/marginal areas (isolated or scattered suitable pixels), providing a more ecologically meaningful representation of tortoise habitat than simple pixel-based classification. Core habitat categories: - Moderate Core: Areas with concentrated moderate-quality habitat (HSI scores 2.00-2.49) - Optimal Core: Areas with concentrated optimal-quality habitat (HSI scores 2.50-3.00) The underlying HSI model integrates eight environmental variables weighted according to published desert tortoise habitat research: soil depth to bedrock (20%), winter precipitation (15%), summer precipitation (10%), elevation (18%), slope (8%), aspect (7%), surficial geology (12%), and vegetation community type (10%). The model is based on Nussear et al. (2009) methodology adapted for Death Valley conditions.
