Return Reference	Explanation
FORM 990	COVID FINANCIAL IMPACTS: APRIL 15 MARKS THE 1ST ANNIVERSARY OF THORNE CLOSING ITS OFFICES DUE TO COVID-19. WITH SCHOOLS CLOSED AND IN-PERSON PROGRAMMING LIMITED, WE HAVE HAD TO PIVOT NEARLY 100% OF OUR PROGRAMS AND OPERATIONS, OFTEN WITH SIGNIFICANT FINANCIAL IMPACT. OUR GOAL HAS BEEN TO ADVANCE OUR MISSION WHILE ADDRESSING THE EMERGENT NEEDS OF THOSE MOST VULNERABLE IN OUR COMMUNITY. FORTUNATELY, OUR LONG-TIME CONTRIBUTORS LIKE THE XCEL ENERGY FOUNDATION HAVE REMAINED LOYAL, AND THE PHILANTHROPIC SUPPORT WE HAVE RECEIVED IN COMBINATION WITH PPP LOANS HAS ENABLED THORNE TO OVERCOME AN ESTIMATED 650,000 IN LOST PROGRAM FEES. WHILE WE HOPE TO RETURN TO OUR NORMAL PROGRAMMING SOMETIME THIS FALL, IT IS LIKELY WE WILL NEED TO CONTINUE TO PIVOT PROGRAMS TO RESPOND TO CHANGING COVID REGULATIONS AND COMMUNITY NEEDS. TO ENSURE THAT WE CONTINUE TO SUCCEED IN NAVIGATING THESE UNCERTAIN TIMES, WE WILL RELY ON THE SAME TWO BUSINESS STRATEGIES THAT HAVE PROVEN SUCCESSFUL THROUGHOUT THE FIRST TWELVE MONTHS OF THE PANDEMIC. FIRST, WE WILL MAINTAIN A STRONG FINANCIAL POSITION THAT ALLOWS FOR RISK-TAKING AND THE PURSUIT OF EXCELLENCE THROUGH PROGRAMMATIC INNOVATION. SECOND, WE WILL UTILIZE PROGRAMMATIC SUCCESSES TO DRIVE PHILANTHROPIC RETURNS. AT THE OUTSET OF THE PANDEMIC, THORNE'S THREE-MONTH OPERATING RESERVE ALLOWED FOR US TO CONFIDENTLY PIVOT STAFF AND FINANCIAL RESOURCES TO NEW COVID RESPONSE PROGRAMS, LIKE NATURE ACTIVITY KITS. THESE EFFORTS TO SUPPORT THOSE MOST VULNERABLE IN OUR COMMUNITY WERE THEN REWARDED BY INCREASED DONATIONS FROM EXISTING DONORS. THESE INCREASED DONATIONS HELPED ENSURE WE HAD THE FINANCIAL RESOURCES NEEDED TO CONFIDENTLY AWARD FULL SCHOLARSHIPS TO 25% OF OUR SUMMER CAMP PARTICIPANTS DESPITE ANTICIPATING SIGNIFICANTLY REDUCED REVENUE FROM THAT PROGRAM. THEN, JUST BEFORE SUMMER CAMP, OUR BUSINESS STRATEGIES PAID OFF WHEN A NEW DONOR STEPPED UP TO FUND 100% OF THE SCHOLARSHIPS. THIS GIFT THEN ENABLED THORNE TO CONFIDENTLY MAKE ITS NEXT BIG PROGRAM PIVOT AND OPEN A MICRO-SCHOOL TO PROVIDE LOW-INCOME FAMILIES ACCESS TO IN-PERSON LEARNING OPPORTUNITIES DURING LOCAL SCHOOL CLOSURES. IT IS THORNE'S GOAL TO CONTINUE FORWARD INTO WHAT IS AN INCREASINGLY UNKNOWN FUTURE RELYING ON THESE TWO BUSINESS STRATEGIES. WE ARE CONFIDENT THAT THIS APPROACH WILL NOT ONLY KEEP THORNE VIABLE THROUGHOUT THE REMAINDER OF THE PANDEMIC BUT ALSO ALLOW US TO BE OF THE GREATEST SERVICE TO OUR COMMUNITY.
FORM 990, PAGE 1, PART I, LINE 6	VOLUNTEER AND IN-KIND SUPPORT PLAY A CRITICAL ROLE IN THE SUCCESS OF THORNE'S MISSION, BY ENSURING ALL PROGRAMS ARE DELIVERED THROUGH THE MOST COST EFFECTIVE MEANS POSSIBLE. VOLUNTEER INVOLVEMENT: IN A TYPICAL YEAR, THORNE NATURE EXPERIENCE UTILIZES APPROXIMATELY 600 VOLUNTEERS AND INTERNS WHO CONTRIBUTE MORE THAN 12,000 VOLUNTEER HOURS. IN 2020, DUE TO COVID-19, THORNE NATURE EXPERIENCE WAS ABLE TO SAFELY ENGAGE 209 VOLUNTEERS CONTRIBUTING OVER 3700 VOLUNTEER HOURS. THORNE IS GOVERNED BY A VOLUNTEER BOARD OF TRUSTEES WHO OVERSEE POLICY LEVEL DECISIONS FOR THE ORGANIZATION, HIRE AND MANAGED THE EXECUTIVE DIRECTOR AND ENSURE THORNE'S FINANCIAL HEALTH AND WELL-BEING. ADDITIONAL VOLUNTEERS AND INTERNS PROVIDED SUPPORT BOTH IN THE OFFICE AND WITH THORNE PROGRAMS. THORNE HAS A SUCCESSFUL INTERNSHIP PROGRAM FOR UNDERGRADUATE AND GRADUATE STUDENTS TO GAIN HANDS-ON EXPERIENCE WITH TEACHING OUTDOORS IN NATURE. TYPICAL VOLUNTEER TASKS AT THORNE INCLUDE ASSEMBLING STUDENT-AUTHORED MINI BOOKS AND CREATING TEACHING PROPS FOR THORNE'S IN-SCHOOL PROGRAM, ASSISTING TEACHERS AND STUDENTS IN THE AFTER SCHOOL PROGRAM, SERVING AS TEACHING ASSISTANTS FOR SUMMER CAMP, IDENTIFYING, AND ERADICATING INVASIVE PLANTS SPECIES AT SOMBRERO MARSH, AND PROCURING AUCTION ITEMS FOR THORNE'S ANNUAL FUNDRAISER, NATURAL NIGHT OUT.
FORM 990, PART III	FIELD TRIP PROGRAM AND SCHOOL PROGRAMS - THESE SCHOOL PROGRAMS ENGAGE MORE THAN 2,600 BVSD AND SVVSD SECOND GRADERS AND NEARLY 500 STUDENTS FROM OTHER SCHOOLS ANNUALLY IN A DAY-LONG FIELD TRIP TO THE 45-ACRE SOMBRERO MARSH ENVIRONMENTAL EDUCATION CENTER IN BOULDER OR SANDSTONE RANCH IN LONGMONT. THROUGH FUN, HANDS-ON, PLACE-BASED ENVIRONMENTAL EDUCATION EXPERIENCES, STUDENTS INTERACT WITH AND LEARN TO CARE ABOUT, THE ECOSYSTEMS AROUND THEM. THORNE'S THREE-VISIT IN-SCHOOL PROGRAM REACHES NEARLY 6,000 ELEMENTARY STUDENTS EACH YEAR. THE PROGRAM EXPANDS STUDENTS' KNOWLEDGE IN THE AREAS OF SCIENCE AND LITERACY THROUGH A SERIES OF LESSONS THAT INVOLVE INTERACTIVE EXPLORATIONS, INQUIRY-BASED EXPERIMENTS, SCIENTIFIC INSTRUMENTS, AND SPECIMENS, AND WRITING A PICTURE BOOK. AT SELECT SCHOOLS, THORNE OFFERS AN ADDITIONAL TWELVE WEEKS OF AFTER SCHOOL PROGRAMMING TO 280 STUDENTS WHO ARE INTERESTED IN FURTHER EXPANDING THEIR KNOWLEDGE OF SCIENCE AND CONNECTION TO NATURE. IN 2020 FALL SCHOOL CLOSURES LEFT FAMILIES IN NEED OF CHILDCARE, ACADEMIC SUPPORT, AND ENRICHMENT ACTIVITIES. IN RESPONSE, THORNE CREATED ITS NATURE LEARNING PODS PROGRAM AND IS OFFERING 40,000 A MONTH IN SCHOLARSHIPS TO PROVIDE LOW-INCOME FAMILIES WITH 30 HOURS/WEEK OF NATURE-BASED PROGRAMMING. ALSO, TEACHERS ARE STRUGGLING TO ADAPT TO NEW LEARNING ENVIRONMENTS. THORNE IS SUPPORTING EDUCATORS BY TRANSLATING 100% OF ITS CURRICULUM INTO HIGH- QUALITY, VIRTUAL PROGRAMS THAT INCLUDE VIDEOS AND ACTIVITIES. EACH PROGRAM IS AVAILABLE IN ENGLISH AND SPANISH. THORNE NATURE PRESCHOOL EXPANSION - THE PANDEMIC INCREASED THE DEMAND FOR SAFE, RELIABLE CHILDCARE OPTIONS FOR YOUNG CHILDREN. IN RESPONSE, THORNE EXPANDED ITS NATURE PRESCHOOL TO LAFAYETTE AND IS PROVIDING OVER 50,000 IN SCHOLARSHIPS TO FAMILIES IN NEED. NATURE FOR ALL - THORNE PROVIDES MORE THAN 400,000 IN CAMP SCHOLARSHIPS AND SUBSIDIZED SCHOOL PROGRAMS TO MORE THAN 7,000 YOUTH FROM LOW-INCOME AND LATINO FAMILIES EACH YEAR (GREATER THAN 50% OF THORNE'S TOTAL PARTICIPANTS). THORNE BELIEVES THAT MORE FREQUENT AND IN-DEPTH INTERACTION WITH PARTICIPANTS INCREASES THE LIKELIHOOD THAT THEY WILL TRULY CONNECT WITH NATURE AND BECOME LIFE-LONG STEWARDS OF THE EARTH. FOR THIS REASON, THORNE HAS DEVELOPED ITS NATURE IMMERSION PROGRAM (NIP), WHICH SEAMLESSLY DELIVERS THORNE'S SUMMER CAMP, FIELD TRIP, IN-SCHOOL, AND AFTER SCHOOL PROGRAMS AT ELEMENTARY SCHOOLS WITH HIGH PERCENTAGES OF UNDERSERVED YOUTH. DUE TO COVID, MANY FAMILIES LACK THE RESOURCES TO SAFELY GET KIDS OUTSIDE. THORNE IS HELPING TO OVERCOME THIS BARRIER BY PROVIDING LOW-INCOME FAMILIES WITH TENS OF THOUSANDS OF DOLLARS IN NATURE EXPLORATION SUPPLIES, BACKYARD CAMPING TENTS, GARDENING TOOLS, TRAIL SNACKS, AND OF COURSE FACE MASKS.
