Big Island State Park will create rare savanna habitat The removal of more than 100 diseased oak trees at Myre Big Island State Park will allow restoration of rare prairie oak oakley outlet prices savanna, according to the oakley glasses online Minnesota Department of Natural Resources. "Oak savanna was once one of the most common vegetation types in the Midwest," said Molly Tranel Nelson, DNR regional resource management specialist. "It was the transitional area between prairies and forests, once covering about 10 percent of the state. Savanna was dominated by scattered oak trees, standing in a diverse mix of native grasses and flowering plants." Since statehood much of the savanna once common to south central Minnesota was cleared for agricultural use. The control of fire allowed unmanaged oak savannas to become choked with vegetation. "Today oak savanna cheap oakley sunglasses for sale is considered one of the rarest plant communities on earth," Tranel Nelson said. Birds such as the eastern whip poor will, red headed woodpecker and northern flicker, flourish in oak savanna. Park Manager Jerry Katzenmeyer said many of the oaks at Myre Big Island State Park are being hit by bur oak blight, two lined chestnut bore or oak wilt. "While it may be surprising to see large, oakley script mature oaks being cut, the reality is that by harvesting the dying oaks, we have a better chance of saving the remaining trees," he said. Oaks in the park will be harvested through the winter. Visitors will see stumps and brush disturbance until the grasses begin to fill in, next summer.
"Restoring oak savanna has long been a goal at the park," Katzenmeyer said. "Removing the dying trees enables us to restore a landscape that existed when the area was first settled.".
