Together with larva of the filbertworm moth (Cydia latiferreana), the filbert weevil feeds on the acorns of several species of oak tree. In British Columbia, up to 66% of acorns from garry oak (Quercus garryana) were infected with these larvae. These acorns are still able to germinate, but the germination rate is lower than for uninfected nuts. [2]
By eating only a small portion of the acorn (and sometimes none at all), these beetles help the seed germinate and become a seedling, which confers ecophysiological and reproductive advantages for the oak tree. [1] [7] Burying the acorns protects them from more efficient seed predators, leads to the developed seedlings having deeper roots, and ...
Oak regeneration failure is a woodland phenomenon whereby insufficient oak seedlings and saplings are recruited into the canopy to replace dead mature oaks.The result is a local decline in oak numbers while other more shade-tolerant trees such as maple, lime, and ash may become more prominent.
A buck works a scrape under the oak trees during a bumper crop year. Whitetails are not choosey as to color and texture, gobbling green apples and scarfing down those hard little acorns covering ...
Many animals eat unripe acorns on the tree or ripe acorns from the ground, with no reproductive benefit to the oak, but some animals, such as squirrels and jays serve as seed dispersal agents. Jays and squirrels that scatter-hoard acorns in caches for future use effectively plant acorns in a variety of locations in which it is possible for them ...
The loss of these oaks can also cause costly problems in city management. Dead bur oak trees pose a problem for the upkeep of urban areas. At $1000 per tree for removal, costs can add up fast. In the state of Iowa, removal can reach over $700,000 trees a year. [7] This could hurt the economies of the areas affected. [8]
It is in the white oak section, Quercus sect. Quercus, and is also called mossycup oak, mossycup white oak, blue oak, or scrub oak. The acorns are the largest of any North American oak (thus the species name macrocarpa, from Ancient Greek μακρός makrós "large" and καρπός karpós "fruit"), and are important food for wildlife.
