Buckthorn, and a Warning to the World

We spent the last couple of days cutting Buckthorn (Rhamnus spp) at a remediation site in Guelph (Eastview) for the City. Every two years, we haul out our brush saws, and for two days we hack back a kilometer, or so, of buckthorn that has taken over an area just off Eastview Road.


We clear a LOT of buckthorn. We clear Buckthorn for the City, we clear Buckthorn for acreage and woodlot owners, and even within the City, when we spot a buckthorn shrub growing along the fence line, we point it out, briefly discuss why it is such a threat to forest ecosystems through Eastern North America, and then offer to remove it.


Now, my point here is that Buckthorn is a terrible, terrible invasive plant. It is spiny, prolific, and difficult to control chemically. It is consuming Native Forests, has demonstrated resistance to climate change, spreading (seemingly unstoppable) and creates a forest-monoculture-desert, absent of food, dominant and destructive.


Buckthorn was introduced by a few landscapers, 150 years ago. They thought that it flowered nicely, and could be an effective means of delineating farm property lines.


Just imagine, then, what CRISP-R might achieve.
