“We are responsible for the third generation of oaks in McHenry County.” Mary Tree McClelland, horticulturist, Glacier Oaks Nursery in Harvard.
To Mary's way of thinking, the first generation of oaks was the one that was here when European-American settlers moved into the county in the mid-1830s. At that time, nearly 40% of McHenry County was covered in oak woodlands or savannas. The remainder of the landscape was prairie, wetland, and open water.
By 1872, settlers had cut half the original oak woods, whittling them down to just 18% of the county, or about 70,000 acres. The second generation of our oaks is the one that sprouted and grew since the 1830s, but they never regained the ground lost in those early years of settlement. In fact, during the second generation, oaks have steadily lost ground to farming and development, so that today, oak woods cover just 4% - 14,000 acres – of the landscape.
Of the remaining oak woodlands, very few, perhaps 25%, are healthy. The vast majority are dying off as oaks are choked by invasive shrubs like buckthorn and honeysuckle, and rapidly-growing trees like box elder. Acorns fall, young oaks sprout, but they never grow to adulthood because they are shaded out by the invaders.
As the second generation of local oaks nears the end of its natural life (200 years?), the county faces the prospect of the third generation being nothing more than a handful of remnants in public natural areas – just like zoo specimens.
There is a different way. The descendants of the early settlers and the new settlers who arrive by the thousands each year have a choice. The community can choose to plant oaks. Not just specimens in backyards, but actually recreating oak woodlands and savannas on the soils where these woodland communities once thrived.
And, our community can choose to take better care of the oak woodlands that remain by clearing invasive brush and giving the young oaks sprouting in the woods a chance to mature.
If local settlers – new and old – choose to help, the third generation of oaks can thrive!
Look for "Oak Rescues" that TLC holds throughout the winter months. These are days when volunteers gather on a privately-owned property for the purpose of helping the landowner clear invasive buckthorn and honeysuckle from around some ancient oaks. We get a good brush fire going, have something warm to drink and even cook some brats over the fire for lunch once the work is done. Contact Linda for more information.
