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.

Sequence of four images, showing the amount of change around the Eckart property in Trinity National Forest in Northern California. The first image marks the deforested areas in 1973 (in yellow), in a 20 kilometer square centered on the Eckart property. The second image is in 1980 and it marks all the areas that have changed classification since 1973. Images that have changed once are in yellowsince 1973 , those that have changed twice are in blue, and those that have changed three times are in red. The third image is in 1987, and the fourth is in 1994.
