Inaugural Cache In Trash Out Event a Success!

The Mississippi National River and Recreation Area hosted its first ever Cache In Trash Out event, calling on geocachers to pitch in and help restore the floodplain forest habitat at Crosby Farm Regional Park. At a typical Cache In Trash Out event, geocaching volunteers remove litter to clean up a local park; however, at this event, the “trash” was the dreaded invasive shrub known as European Buckthorn, which has invaded the forest and threatens to take over the entire ecosystem at Crosby Farm Regional Park.

Participating volunteers received coordinates to the event where they were met by National Park Service Rangers ready to lead them in the habitat restoration event. Geocachers worked hard to remove the pre-cut woody trash from the forest, hauling and stacking overgrown buckthorn in enormous piles for later removal by Saint Paul Parks.

The Mississippi National River and Recreation Area has been working in cooperation with Saint Paul Parks to manage invasive species in parks like Crosby Farm Regional Park. Thanks to the efforts of volunteers the park is undergoing a dramatic transformation as non-native plants are removed and native plants are being re-established.
