*To our valued climbers in South Suburban Parks & Rec District (ssprd), South Platte Park, Littleton: You may have heard by now that our recreational tree climbing programs are no longer being offered at South Platte Park. Our programs at SPP had always been very popular, usually with waiting lists and requests for additional special climbs from area residents. This why we wanted to give you more detail as to why this happened, and also let you know that we offer recreational tree climbing programs for individuals, families, birthdays, scout groups, etc. at various sites along the Front Range, including through the recreation departments of Golden, Lafayette, and Longmont. Please check our calendar below for dates and links to register for a climb.

As to the reason for the South Platte Park situation: Due to new administrative personnel at ssprd, a directive was issued mandating background checks on all outside contractors offering programs within the district. We have no problem with checks in principle. However, ssprd outsourced this task to a little-known private, out of state company, a company which then demanded we turn over our social security numbers to them to facilitate their investigation. With the increasing risk of identity theft, the commonly used alternative of substituting other identifiers such as drivers license numbers to obtain needed personal data, and the widespread advice to only provide one’s SS# to financial and government services, we declined to reveal our social security numbers to this private outside company, while still offering to work with them on alternatives. Despite the best efforts of the great staff at South Platte Park, whom we’ve known and worked with for almost 20 years, the new district personnel told us that we and our programs were no longer wanted.

We love connecting people of all ages with trees and forests. But sometimes, and increasingly, administrators put process and the perceived needs of bureaucracies ahead of people and the humanity of what we’re trying to do. We hope to see all of you at one of our other great trees, and we invite you to reach out to us with any questions or thoughts, at Harv at treeclimbingco com. Until then, thank you for your passion for nature. We’ll do our best to honor that shared passion and pledge to continue to be of service to people and nature.
