To serve the growing Preserve, MSC trained 133 new stewards (a 50% increase over the preceding year) which helped to surpass 500 active stewards. Stewards devoted almost 40,000 hours to patrolling and maintaining trails, welcoming visitors, and educating the community through hikes, outreach programs, school tours and other key activities.
