English: United States Department of Agriculture—USDA Natural Resources Conservation Service distribution maps of the Flora of New York.


Note
  • The USDA PLANTS Database contains the disclaimer:
  • Our county data are based primarily on the literature, herbarium specimens, and confirmed observations. However, not all populations have been documented, so some gaps in the distribution shown above may not be real.
  • Remember that only native and naturalized populations are mapped.
  • These maps have been modified from the originals as follows:
  • Width was reduced from 600px to 500px by reducing horizontal resolution (to remove stretch).
  • Height was reduced from 450px to 375px by cropping the "PLANTS Database" logo from the bottom and taking a little off the top to center the map vertically.
  • Format was changed from JPEG to 8-color indexed PNG with no dithering, as a quick way to get rid of the more obvious high-compression JPEG artifacts in the original, while reducing file size.
  • This mode change usually, but not always, results in the field colors RGB(225-235-224) and (121-204-132). The very rare obvious deviations have been fixed.
  • More recent maps have been converted to the indexed mode using the fixed color table:
00 00 00   FF FF FF   82 CC 82   E0 EB E0
33 33 33   66 66 66   99 99 99   CC CC CC
  • This precludes the rare occasions of a missing color (like when the only reports of a plant have been from ballast piles in The Bronx).
