Marsh plume thistle (Cirsium palustre), listed as a noxious weed in BC’s Central Interior by the Invasive Plant Council of BC, is showing it’s presence in ALRF’s harvest areas. The plant grows in moist locations and competes with native plants and crop trees. A containment program for this purple-flowered plant is currently underway in the Central Interior aimed at preventing its expansion. According to the IPCBC the most effective way to limit the spread of the species is by cutting the plants down before they go to seed. Other methods such as biological controls and herbicides are in development.
Last summer, several harvest areas on the Research Forest were surveyed for invasive plants and several species were found in varying quantities. This provides excellent baseline information to help ALRF monitor increases and decreases in the diversity and abundance of invasive plants and to implement strategies for managing them.
Is it drought? Is it the late spring frosts we had this year? Perhaps it’s the famous Aleza Lake mosquitos…?
There are several disappointed bears and field workers out there who can’t grab and quick snack in the woods this summer – present company included! After several seasons of abundant huckleberry and blueberry crops at the Research Forest over the past few years, this growing season is turning out to be quite a change. Not only are the plants not producing berries, some of the patches are actually missing leaves, with the bare stems showing a carpet if grey like a stand of mountain pine beetle killed trees.
What happened to the berries? If anyone can answer this question, please post a comment!
Three foresters from Germany visited ALRF earlier this month as one of many stops on a three week tour of the Pacific Northwest. This group is part of a government training program in Germany where new recruits are required to travel and observe forest management practices in other countries. In addition to visiting the Ancient Forest and ALRF, Jon, Steffen, and Hendrik’s trip also includes the Yukon, Oregon, Washington, Vancouver Island and the Malcolm Knapp Research Forest.
