| IFW_dwa_organized | This data set includes deer wintering areas in organized townships that qualify as Significant Wildlife Habitat under Maine's Natural Resources Protection Act. Deer Wintering Areas (DWAs) are forested areas used by deer when (a) snow gets more than 12 inches deep in the open and in hardwood stands, (b) the depth that deer sink into the snow exceeds 8 inches in the open and in hardwood stands, and (c) mean daily temperature is below 32 degrees Farenheit. This data set includes DWAs in organized townships that qualify as Significant Wildlife Habitat under Maine's Natural Resources Protection Act as mapped by MDIFW Regional Biologists. Please refer to the metadata for complete information. | 6/2009 |
| IFW_iwwh | Inland Waterfowl/Wading bird Habitat (IWWH), a Significant Wildlife Habitat defined under Maine's Natural Resources Protection Act (NRPA). IWWHs with a high or moderate rating meet the Significant Wildlife Habitat definition and are protected under NRPA. Low-rated IWWHs are NOT included in this layer because they do not meet the definition and are not protected under NRPA. Each IWWH boundary includes a 250-foot upland zone around the wetland perimeter (buffer excludes developed areas). Data developed by MDIFW. See metadata in ArcCatalog. Downloaded from MEGIS 1/2012. | 9/2012 |
