Jul 23, 2012 • The My American Landscape Winners include: Lee County, Florida , Submitted by Carole Holmberg

Summary: The landscape of Lee County, Florida, has changed dramatically as its population greatly expanded over the last 40 years. Much of the area’s unique landscape of coastal mangroves, marshes, cypress forests, and upland pine flat woods and prairies have been replaced by homes, roads and new bodies of water that are being used by industry.

Maricopa County, Arizona, Submitted by Michelle Fuller

Summary: Arizona’s capital of Phoenix and neighboring towns in Maricopa County have undergone a major population boom in the last 40 years. The effects of this boom are seen in everything from the expansion of town and cities to an increased demand for fresh water. Michelle Fuller from Gilbert wrote asking to see these changes to the landscape; most visible in this series of images is how city streets and development are now covering the land that previously was used for agriculture.

North Central Colorado, Submitted by Justin Hirsch

Summary: The forests of northern Colorado have gone through many changes driven by both natural and human causes. Justin Hirsch from Steamboat Springs was interested in seeing the dynamic changes to the forest caused by mountain pine bark beetles. In this pair of Landsat images from 2001 and 2010, the tree die-off from the insect infestation is visible.

Nebraska Sandhills, Submitted by Mary Ann Vinton

Summary: The Nebraska Sandhills region is one of the largest areas of mostly intact grassland ecosystems in the country and has the largest grass-stabilized sand dunes in the world. Mary Ann Vinton from Omaha is interested in how these hills have changed since the 1970s. The spread of center-pivot irrigation that taps directly into the vast underground Ogallala Aquifer has meant that agriculture has slowly taken over the landscape.

Vermilion Parish, Louisiana, Submitted by Brent Yantis and Whitney Broussard

Summary: The landforms of southern Louisiana have been shaped by the wanderings of the lower Mississippi River, but with modern engineering of where the river flows, the salt marshes of the Chénier Plain are in a battle with the open ocean eroding the coastline. Brent Yantis and Whitney Broussard are interested in telling the story of the changing coastline.

Trinity County, California, Submitted by Roger Eckart

Summary: Forest fires and logging are the two main drivers of change in this area within Trinity National Forest in northern California. Roger Eckart and his siblings bought a grandfathered-in piece of private land within the forest in 1972 and so together the Eckart family and the Landsat program have observed changes in the forest for over 40 years.
