My name is mark and I run the restoration project in the Duwamish Greenbelt for The Nature Consortium. The marginal mountain bike runs directly through a 4 year old restoration project. Weedwackers are undoing 4 years of work in 4 minutes. I have spoken with one active bike group and have asked for a moratorium on building any new trails in the Greenbelt until we can sit at a table and come to an agreement. That group informed me that there were others active in the Greenbelt as well. The Nature consortium supports multiple use of the Greenbelt. If you or anyone you know is working on this project please cease building new trails and contact me immediately at buphalo@naturec.org. We would like to work together for everyone's benefit. Also, the use of chainsaw and weedwackers is illegal in the Greenbelt - we can't even use them for restoration work without approval from the city.
