Data for modeling American chestnut distribution circa 1940 in Monroe County, New York State, US

Contained in this item are data to perform species distribution modeling or related analysis of American chestnut distribution in the mid-20th century in Monroe County, New York State, US. Modeling in the associated study was original performed using MaxEnt 3.4.4 software, but the data in this item could be used for training a species distribution model using any presence-only modeling technique. This item contains two files:

"castanea_dentata_1940.csv" is a CSV file containing the estimated locations of woodlots 1938-1940 where American chestnut was observed. It contains latitude and longitude columns, with coordinates stored in the State Plane New York West coordinate reference system (NAD 1983, meters, WKID 32117). Data are based on maps from the following publication:

Shanks, R.E., 1966. An ecological survey of the vegetation of Monroe County, New York. Proceedings of the Rochester Academy of Science 11, 105–255.

"predictors_ascii_10m.zip" contains zipped ASCII gridded data layers for 11 environmental variables. Data are provided at 10 m resolution, and are stored in the State Plane New York West coordinate reference system (NAD 1983, meters, WKID 32117). Sources for the data, and software to create the data layers, are as follows:
