In addition, SSI provided scientific technical support to Bear Yuba Land Trust on a meadow restoration project, and community support in developing meadow restoration projects on private land. Finally, SSI continued working with both federal and NGO partners in designing spawning habitat projects upstream of the Beale Air Force Base project on non-federal land. 339370 Education: In 2023, the SSI Education team completed the final year of implementation of the National Science Foundation-sponsored Our Forests project. This project included direct educational support of teachers and students learning about Forest Health and Fire Ecology while collecting data through hands-on Field Investigations to then provide their own interpretations of forest health and recommended management activities to regional land managers. UC Davis research partners then continued data collection on student learning outcomes as part of their research on how hands-on science activities influence student science agency. The program also began development of new educational activities with funding proposals submitted to begin new projects in 2024. 99780 Monitoring and Research: In 2023, SSI researchers continued water quality and benthic ecological monitoring of sites throughout the Yuba and Bear River watersheds to continue to establish baseline conditions and monitor responses to stress. These data were utilized to complete a study examining Sierra stream response to drought and flood stress, along with preliminary explorations of how these results influence understanding of climate change impacts on our region. Finally, SSI completed the final year of fieldwork on a project supported by the California Institute for Biodiversity to generate genetic libraries of benthic taxa in our region to support the continued rollout of environmental DNA tools. This project will improve accuracy of eDNA tools and improve monitoring capacity of small organizations. 1093005 true false false false false false false false false false true false false false true false true false false false false false false false false false false false false false false false false false false false false false true false false false false false false false false true 30 0 true 21 true false false false false false false false 0 false false false false false false false X 10 10 false false false false false false false true false false false true true true true false false false false false CA X X Carrie Ammerman 5304777132 117 New Mohawk Road Nevada City CA 95959 Jeff Lauder Executive Dir. 40.00 0.00 X X 86300 0 0 Marsha Burch Director 2.00 0.00 X 0 0 0 Lang Waters President 5.00 0.00 X X 0 0 0 Louise Johnson Secretary 2.00 0.00 X X 0 0 0 Leslie Estes Director 2.00 0.00 X 0 0 0 Inge Ivens Treasurer 3.00 0.00 X 0 0 0 Poyom Riles Director 1.00 0.00 X 0 0 0 Lynn Barakos Director 2.00 0.00 X 0 0 0 Alex Palm Director 2.00 0.00 X 0 0 0 Dave Herbst Director 4.00 0.00 X 0 0 0 Peter Hollingshead Director 2.00 0.00 X 0 0 0 86300 0 false false false 0 1283248 151175 40876 1434423 Fee for Service 95757 95757 Sales 352 352 96109 564 564 0 0 0 0 0 0 0 Loan Forgiven 13000 13000 Other Income, refunds, rewards 5805 5805 Program Tuition Income(refund) 18805 1549901 114914 564 X 0 0 0 0 86300 38943 46279 1078 0 751000 550400 188086 12514 0 11400 11400 68174 48103 18932 1139 0 0 0 0 0 0 275735 237223 35330 3182 0 0 0 0 43796 43513 283 38648 28596 9281 771 0 0 0 0 18242 18242 13709 13709 Miscellaneous 105934 104028 1774 132 Project/Program Lab Supplies 48085 47706 379 Operating Expenses Supplies 40884 36949 3658 277 In-Kind Expenses 39644 39644 7552 1057 3729 2766 1549103 1093005 433956 22142 87542 62758 128321 99599 0 174204 244333 0 0 0 0 0 97957 29667 58099 68290 38922 50043 0 0 0 1994 1995 489082 527018 51099 102117 15632 2933 13000 7712 30549 87443 135599 X 399121 391419 2518 401639 391419 489082 527018 X 798 10576 -21594 X false true X false true true X 188065 228563 980491 1139982 1393547 3930648 63846 96109 159955 0 0 0 188065 228563 980491 1203828 1489656 4090603 0 0 4090603 88 146 1659 66 564 2523 0 88 146 1659 66 564 2523 0 103290 2054 18805 124149 188153 228709 1085440 1205948 1509025 4217275 0.97000 0.96270 0.00060 0.00070 X 5313 1936 3377 92644 27731 64913 68290 Payroll Liabilities 30549 30549 1560477 10576 10576 1549901 1549901 1549103 1549103 1549103 Volunteer Hours 40876 false false false Form 990, Part VI, Section B, Line 11b No review was or will be conducted.
