description: These data are results of prioritization for watershed protection and restoration in Hawaiʻi County Department of Water Supply priority areas as completed in a UHERO study and published in the Journal of Environmental Management.  Continuous rasters give actual values of estimated groundwater recharge saved. Data are provided in imperial (million gallons per acre over 50 years OR gallons per acre per day) as well as metric (thousands of cubic meters per hectare over 50 years OR cubic meters per hectare per day). For priority rasters, values are as follows: 0: outside priority area; 1: priority 1 (highest priority); 2: priority 2; 3: priority 3; 4: priority 4; 5: priority 5 (lowest priority); 6: no change in recharge; 7: negative change in recharge (only relevant for reforestation rasters).   The Protection_Benefits  folder contains priority rasters estimating recharge benefits through protecting native forest from invasion and conversion to non-native forest and non-native grassland.  Within this folder are the following rasters:1. invasion_priority_cumulative_nonnative_10 --- prioritization of benefits over 50 years from native forest protection assuming equal fog interception in native and invaded forests (priority rankings 1-5; 0=outside priority area; 6=no change). Priority 1=>5.2 million gallons per acre (>48.6 thousand m3 per hectare); Priority 2 = 4.0-5.2 million gallons per acre (37.4-48.6 thousand m3 per hectare); Priority 3=2.8-3.9 million gallons per acre (26.2-37.3 thousand m3 per hectare); Priority 4= 1.6-2.7 million gallons per acre (15.0-26.1 thousand m3 per hectare); and Priority 5=<1.6 million gallons per acre (<15.0 thousand m3 per acre).2. invasion_priority_cumulative_nonnative_09 ---prioritization of benefits over 50 years from native forest protection assuming 10% lower fog interception in invaded forests vs. native forests (priority rankings 1-5; 0=outside priority area; 6=no change). Priority 1=>5.3 million gallons per acre (>49.6 thousand m3 per hectare); Priority 2 = 4.1-5.3 million gallons per acre (38.4-49.6 thousand m3 per hectare); Priority 3=2.9-4.0 million gallons per acre (27.1-38.3 thousand m3 per hectare); Priority 4= 1.7-2.8 million gallons per acre (16.0-27.0 thousand m3 per hectare); and Priority 5=<1.7 million gallons per acre (<16.0 thousand m3 per acre).3. invasion_snapshot_priority_nonnative_10 --- snapshot prioritization of annual benefits of forest protection assuming full invasion and equal fog interception in native and invaded forest (priority rankings 1-5; 0=outside priority area; 6= no change). Priority 1=>670 gallons per day per acre (>6.3 m3 per hectare per day); Priority 2 = 580-670 gallons per acre per day (5.4-6.3 m3 per hectare per day); Priority 3= 490-579 gallons per acre per day (4.6-5.3 m3 per hectare per day); Priority 4= 400-489 gallons per acre per day (3.7-4.5 m3 per hectare per day); and Priority 5=<400 gallons per acre per day (<3.7m3 per acre per day).4. invasion_snapshot_priority_nonnative_09 --- snapshot prioritization of annual benefits of forest protection assuming full invasion and 10% greater fog interception in native vs. invaded forest (priority rankings 1-5; 0=outside priority area; 6=no change).  Priority 1=>750 gallons per day per acre (> 7.0 m3 per hectare per day); Priority 2 = 650-750 gallons per acre per day (6.1-7.0 m3 per hectare per day); Priority 3= 550-649 gallons per acre per day (5.2-6.0 m3 per hectare per day); Priority 4= 450-549 gallons per acre per day (4.2-5.1 m3 per hectare per day); and Priority 5=<450 gallons per acre per day (<4.2 m3 per acre per day).The Reforestation_Benefits folder contains the prioritization raster estimating recharge benefits through  reforestation of non-native grasslands. Raster list:5. reforestation_priority -- prioritization of benefits over 50 years from reforestation (priority rankings 1-7; 0=outside of priority area; 6=no change; 7=negative change).   Priority 1=>9.5 million gallons per acre (>88.9 thousand m3 per hectare); Priority 2 = 7.5-9.5 million gallons per acre (70.2-88.9 thousand m3 per hectare); Priority 3=5.5-7.4 million gallons per acre (51.4-70.1 thousand m3 per hectare); Priority 4= 3.5-4.4 million gallons per acre (32.7-51.3 thousand m3 per hectare); and Priority 5=<3.5 million gallons per acre (<51.3 thousand m3 per acre).
