DownloadableForest clearing detected via remote sensing in New HampshireWe used the Global Forest Change dataset (Hansen et al. 2003) to group loss pixels by year of loss, and restricted possible timber clearings to those ≥3.0 ac in size. Resulting polygons are assigned a year of harvest between 2001 and 2018. To detect areas of forest clearing in the state of NH.2000-01-01 to 2018-12-31
DownloadableForest clearing summarized by countyPolygons of forest clearing were grouped by county. A timber clearing polygon was assigned to a county or land ownership type based on the location of its centroid. To summarize forest clearing by county.2000-01-01 to 2018-12-31
DownloadableForest clearing summarized by land ownership typeForest clearing polygons were assigned to a county or land ownership type based on the location of its centroid. We converted the forest cover dataset by Hansen et al. (2013) to create a forest-non/forest image, where pixels with ≥30% tree cover were considered forest. We used this forest cover dataset to estimate the proportion of forestland. To summarize forest clearing by land ownership type.2000-01-01 to 2018-12-31
