Current Issues Facing Native Seed...
Transcript of Current Issues Facing Native Seed...
Seed Specifications • Developing • Examples
Species Availability• Cultivated Species• Collections
National Seed Strategy• Challenges
Form of communication• Industry will recognize the demand
Steps in Developing• Determine species• Determine species percentages• Determine rates (in PLS lbs.)
Develop a wish list
Consider existing vegetation
Consider climate & soil types
Ecological Literature
Discuss with local expertise
Develop a revised list
Determine availability*
Produce the final list
Use acceptable varieties or cultivars and collections from similar geographic areas.
• May be necessary for larger projects• Readily available • Prices are typically less
Use local sources within a specific geographic range.
• Better suited for small projects• Plan ahead• Cost prohibitive
Use both (Known sources UP Materials)
Determine desired percentages of grasses, forbs and shrubs
Determine species most likely to succeed short term and long term
Determine individual species percentages
Percentages based on seeds not by weight.
Determine desired number of Pure Live Seed (PLS) per square foot
• PLS = % Germination x % Purity
Calculate planting rate• Planting rate of commercial seeds in
PLS lbs/acre
Species list with both common and scientific names
Rates specified in PLS lbs./acre
Notes of any special requirements

Crop failure (weather, insect predation, disease)
Increase in demand
Requests for materials the reclamation industry has not typically neededor wanted in the past
SEED
Grass species are typically easiest to acquire.
Farm cultivated & Machine harvested
Some forbs are field produced, but most are collected
Find large enough stands to collect
Must obtain permission/permits
Must monitor stands
Must organize and time collections perfectly
Vision- Right Seed Right Place Right Time
Mission- Ensure availability of genetically appropriate seed to restore viable and productive plant communities and sustainable ecosystems.
Increased demand for locally adapted seed
Increased need for communication with researchers and land managers.
Increase in resources
Collections• More & Smaller• Planning Efforts
Grow Out Contracts• Smaller Fields
Inventory• Storage• Risk
With the National Seed strategy there is an anticipated increase in demand for local seed
A key to meet this demand will be increased communication
Seed specifications can be one effective tool for communication
