Native Plant Development for
Reclamation in Alaska
Paul Krabacher, Bureau of Land ManagementMike Duffy, AK Natural Heritage Program
OBJECTIVE
To supply seed for BLM and its partners with native species - collected, cleaned, increased, and stored in Alaska
Native Plant Materials Development Program
Increase the diversity and amount of native seed available for stabilization, rehabilitation and restoration efforts on lands managed by various agencies
Native Plant Materials Development Program
In light of perceived climate change impacts and human-caused disturbance:
1. Collect workhorse species2. Collect range margin and
other species of interest
•Part of the National Native Plant Materials Development and Conservation Program
•National Native Seed Collection ProgramCoordinated by BLM
Alaska’s ListCollections made
•2002 – 2008100+ collections

2010 Collections of Conservation Significance
• Botrychium alaskense (G2G3 S2S3) is new to the Seward Peninsula; it is widely disjunct and represents the most northwestern occurrence in the state.
• A large population Botrychium virginianum (G5 S2) plants was found on Turnagain Arm.
Iowa State Herbarium
2010 Collections of Conservation Significance
• Astragalus agrestis (G5 SP) from the Copper Center area, which is apparently new to the state.
• Potentilla cf. fragiformis (G4 S1S2) was collected from Salmon Lake, Seward Peninsula - sent to ALA for review (gap-filling/few records for N America)
2010 Collections of Conservation Significance
Range Extensions:• Vahlodea atropurpurea was found on the
Seward Peninsula. This represents a range extension of over 600 km.
• Aquilegia brevistyla, Carex bicolor, Carex eleusinoides, Carex supina ssp. spaniocarpa, Rumex sibiricus, and Silene taimyrensis represent smaller range extensions or additional records of recent range extensions.
• Two aquatic liverworts, Riccia fluitans and Ricciocarpus natans uncommon in the state, were also encountered.
2010 Notes: TRACKED OR SIGNIFICANT RANGE EXTENSIONS
• Artemisia senjavinensis G3 S2S3• Astragalus agrestis G5 SP, new to Alaska• Botrychium alaskense G2G3 S2S3, large range extension• Botrychium virginianum G5 S2• Carex phaeocephala G4 S3• Draba ruaxes G3 S3• Lycopus asper G5 S1• Papaver walpolei G3 S3• Potentilla drummondii G5 S2• Potentilla fragiformis (if so) G4 S1S2• Riccia fluitans rare (?)• Ricciocarpus natans notable• Stellaria dicranoides G3 S3• Vahlodea atropurpurea large range extension• Viola selkirkii G5 S3
