Join FOSS By joining FOSS, your membership fees go towards creating and maintaining the extensive trail network in Myra-Bellevue and Okanagan Mountain Parks. The 2003 fire that started in Okanagan Mountain Park and spread to Myra-Bellevue Park has increased the need for trail maintenance to a level that volunteers alone cannot fulfill. FOSS hires contractors to keep up with the increased water erosion repairs and windfall tree clearing required and this creates the need for additional funding. How to Join Sign up on-line and pay by credit card or with a PayPal account. You can also print a membership form, fill it out and mail it to FOSS. How to Volunteer FOSS members can adopt a trail and perform trail brushing and other trail maintenance as required. FOSS will provide instruction and the tools required. To adopt a trail, send an e-mail stating your interest in the program. Another way to volunteer is to follow the Trail Work Day notices posted on the FOSS-Kelowna Facebook page. The details of the Trail Work Day will by posted at that time. FOSS always welcomes new people who are willing to help.
