計畫資料
Development of a centralized database of wildlife road mortality, wildlife road crossing, and related habitat data for individual species for which data exists throughout the state of Vermont. This involved updating an existing database developed for a complimentary project designed to compile all existing data on black bear road mortality, road crossing, and significant habitats. It also included incorporating all data on moose collisions and deer collisions. In addition, new databases were developed to record existing bobcat, amphibian and reptile information. In order to expand and improve wildlife road mortality data, a partnership and recording procedures were developed with VTrans field/district staff enabling them to record a new array of wildlife road mortality information.

取樣方法
The two agencies responsible for this information have different recording techniques and levels of accuracy. F&W information has been recorded through various methods. F&W initiated a statewide black bear GIS database in 2001, collected from written documents at district offices and interviews to collect data back to 1971. Moose data came from game wardens and biologists that was entered into the state police CAD system. The records have been populated through various methods such as distance from intersection, landmark, location maps, GPS coord, and others. Though most have much better accuracy, records included in this database have proven to have a locational accuracy threshold of less than 0.5 mile. Starting in 2004, VTrans road maintenance staff recorded data in an ongoing maintenance tracking system.

| 品質控管 | In a quality assurance review by F&W, a locational accuracy acceptance threshold was created. Vermont Center for Ecostudies reviewed the data in 2024, assigned or reassigned coordinates that had been left blank or incorrectly georeferenced, and performed additional quality control on the data. An R script containing the quality control process transforming the original data from the Vermont Center for Geospatial Data, where it is archived, is available on request. |
方法步驟描述:
- Removed entry-error duplicate records.
- Assigned animals from their provided entry categories and comments to taxonomic names, sexes, age classes, and vitality. Many could not be assigned in full detail. Animals assumed dead unless otherwise specified.
- Corrected georeference of points where lat/long data was missing or incorrect.
- Split out multiple animals at different locations from records whose comments confirmed their presence.
- Corrected town and county locality assigned to points using spatial layers of towns and counties from VT Center for Geographic Information.
