Seed Mixes

Description This data is designed to assist preparing the SWMP for projects and supply Maintenance projects that need seed mixtures for work along Region 2 highways. Also, these seed mixtures are available in a digital format in ARC/GIS layer for CDOT’s OTIS Highway Map System. The intended users are Environmental, Engineers, and CDOT maintenance staff. However, there are limitations and assumptions that were considered when developing these seed mixtures. Assistance from the environmental staff is strongly recommended before using a seed mixture. Site specific conditions may require adjustment to the seed mixture(s). The seed mixtures contained in this dataset 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) Last Update 2014 Update Frequency Not planned Data Owner Region 2 Data Contact Region 2 Environmental Specialist or Water Pollution Control Manager Collection Method Projection NAD83 / UTM zone 13N Coverage Area Region 2 Temporal Disclaimer/Limitations There are no restrictions and legal prerequisites for using the data set.
