Description: This data was collected by CDOT maintenance crews and represents roadkill collected from 2005 - 2011. This data does not include animal/vehicle collision data collected by the Colorado State Patrol, but is useful to determine where, and to what magnitude, deer and elk are unsuccessfully attempting to cross Colorado highways
Description: When a species is proposed for listing as endangered or threatened under the Endangered Species Act, the U.S. Fish and Wildlife Service must consider whether there are areas of habitat believed to be essential the species’ conservation. Those areas may be proposed for designation as “critical habitat.” Critical habitat is a term defined and used in the Act. It is a specific geographic area(s) that contains features essential for the conservation of a threatened or endangered species and that may require special management and protection. Critical habitat may include an area that is not currently occupied by the species but that will be needed for its recovery. An area is designated as “critical habitat” after the Service publishes a proposed Federal regulation in the Federal Register and receives and considers public comments on the proposal. The final boundaries of the critical habitat are also published in the Federal Register.

Description: Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2005). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

A 5 meter offset tolerance was used to make any geometry shifts very negligable.

Description: Absence of wetland polygons within an area does not indicate absence of wetlands. Additionally, wetland delineations legally expire after five years. Data found on this GIS platform should not be used in lieu of field investigations.

Description: The seed mixtures contained in this document are designed for the site specific conditions (e.g., soil texture and chemical composition, precipitation, elevation, aspect, etc.) associated with the approximate mile marker along Region 2 highways. Native species were selected for the seed mixtures with few exceptions. The individual plant species were selected based on their adaptions to the site conditions, ability to control erosion, and compatibility to establish a diverse plant community. The species composition of the seed mixture was also based on the recommendations found in the Natural Resources Conservation Service’s (NRCS) “Major Land Resource Areas (MLRA).”(http://www.nrcs.usds.gov)

Description: LWCF post-completion compliance responsibilities apply to each area or facility for which Land and Water Conservation Fund assistance is obtained consistent with the contractual agreement between National Park Service and the State.The State is responsible for compliance and enforcement of these provisions for both State and locally sponsored projects. Responsibilities cited in Title 36, Part 59 in the U.S. Code of Federal Regulations (LWCF act of 1965) apply to the area described on the 6(f)(3) boundary map and/or as described in other project documentation approved by the Department of the Interior.Section 6(f)(3) of the LWCF Act requires: No property acquired or developed with assistance under this section shall, without the approval of the Secretary, be converted to other than public outdoor recreation uses. The Secretary shall approve such conversion only if he finds it to be in accord with the then existing comprehensive statewide outdoor recreation plan and only upon such conditions as he deems necessary to assure the substitution of other recreation properties of at least equal fair market value and of reasonably equivalent usefulness and location.Field DescriptionsPropID: Each LWCF property has a unique property identification number that represents a site (usually contiguous) that should be inspected as a single unit.GrantID: The grant number associated with the footprint, displayed in integer format. The number is assigned by the NPS, using the following convention: [2-digit state FIPS ID]-[5-digit incrementing grant number]PropNameOfficial: The property name that the sponsor publically uses to identify the LWCF property. This is a way to have the properties labeled so that the field and public can recognize the property.PropNameAKA: An alternative property name known to the public/sponsor that differs from the PropName.PropNameOld: The original property name when the grant was executed, and has since been officially changed to the PropName.ControlType: Type of asset control the Sponsor has on the parcel.EffectiveDate: The date that the grant closed, found in the physical grant file, used as the beginning date of the LWCF encumberment.TerminationDate: Date that encumberment will expire, this would be for leases, etc. If the parcel is fee title or some type of perpetual agreement or easement, then there is no termination date (12/31/9999 is used).SpatialSource: The GIS layer sourced to create the LWCF footprint polygon geometry.Comments: A brief description of the grant purpose, and any notes regarding a flagged footprint or potential issues with the footprint (i.e. conversion, geometry, changes, etc.).MappingStatus: The mapping status of the footprint - footprints are flagged when there is an issue with geometry, the 6f map, conversion, or other reasons that require further staff review.ApprovalStatus: The approval status of the footprint.Acres: Area in acres (US) as calculated by ArcGIS.SHAPE_Length: Length in meters as automatically calculated by ArcGIS.SHAPE_Area: Area in meters squared as automatically calculated by ArcGIS.
