    dct:description "This data set is a polygon representation that estimates the geographic area in which cedar decline is occurring. Cedar Decline refers to the dying or decline of yellow-cedar (Chamaecyparis nootkatensis) forests of southeast Alaska and is characterized by red foilage in trees currently dying, or by white-gray snags of old mortality. Mapped snags can be standing dead as long as eighty years. The data was collected via aerial sketch mapping techniques and recorded on 1:250,000 from 500-3000 foot above ground level(AGL). Survey coverage has been most intense for forests adjacent to shorelines and waterways. Data is collected, refined and updated on an annual basis." ;
