Questions about wetland location and use should be referred to the ANR DEC Wetlands section, 802-244-6951. NWI maps were used by the State of Vermont Agency of Natural resources as a means of creating this data layer in conjunction with the VSWI. The NWI and VSWI were joined by a union, to create the new 2010 Vermont Significant Wetland Inventory data layer, representing Vermont's regulatory wetlands. The VSWI prior to 2010 was created by hand digitizing nearly two-thirds of Vermont's wetlands from RF 24000 scale NWI mylars. The remainder of the state was scanned from RF 24000 or RF 25000 scale mylars.These mylars were created by transfering wetland polygon boundaries from RF 62500 scale NWI mylars to RF 24000 scale base maps.</SPAN></P></DIV></DIV>

This data layer is intended for planning and informational use, to alert the public to the presence of regulated wetlands. This data layer is not designed to be used as sole criteria in any decision making process. Questions about wetland location and use should be referred to the ANR DEC Wetlands section, 244-6951.
This is a digital "representation" of Vermont's Significant Wetlands Inventory. The majority of the wetlands were derrived from NWI maps and prior VSWI data layers which were digitized from USFWS NWI maps. The 2008 National Wetland Inventory was unioned with the VSWI layer of 2009. The two datasets were then dissolved based on their class and all attributes of the NWI and VSWI were kept where unique. The wetlands in the WaterWetlands_VSWI coverage are mainly palustrine complexes (regulatory). A smaller subset of the data define riverine and lacustrine wetland complexes (regulatory). Single line streams are not included. The wetlands in this coverage are those regarded as regulatory by the VT Water Resources Board. They correspond to the outer boundaries of palustine areas mapped by the USFWS NWI section with the following exceptions (includes some riverine and lacustrine wetlands). See Feature Accuracy for details on the accuracy of the source maps.This data layer is intended for planning and informational use, to alert the public to the presence of regulated wetlands. This data layer is not designed to be used as sole criteria in any decision making process. Questions about wetland location and use should be referred to the ANR DEC Wetlands section, 244-6951.
The data was developed and QA/QCed in several phases. Attributes consist of those from the NWI and the VSWI where unique.
The wetland boundaries are very approximate due to the methods used to generate the original maps. Errors of as much as 500 meters have been observed when clearly identifyable boundaries were plotted over RF 5000 scale orthophotos. Most boundaries are expected to be within several hundred meters of their true locations. However, not all wetlands appear on the NWI maps, and some non-wetland areas may appear as wetlands. Review of the NWI maps by the Wetlands Office of the VT Agency of Natural Resources has shown that only a very small percentage (estimated at 1-2%) of the wetlands on the NWI maps are not found on the ground; many of these have been filled in since the 1977 inventory. It is also estimated that there are about 25% more wetlands than appear on the NWI maps, most of these being below 3 acres in size (often closed-canopy wetlands or open water). Discrepancies have been noted between the original 1977 NWI maps and a more recent inventory along the Connecticut river. For more information on the accuracy and use of the NWI maps, contact the Wetlands Office of the Agency of Natural Resources

Preliminary release data available statewide (except for several missing USGS quads in QUAD16 tile 45). Data are topologically correct, but attributes and linework are currently being verified. All areas where data were previously available have been superceded by updated ANR data. Operator - Steve Bower, VCGI

In order to provide ANR and the public a coherent and manageable spatial product representing Vermont's regulatory wetlands the internal boundaries of the VSWI (first release 2010) have been dissolved. The dissolved product allows ANR wetland scientists to effectivelty manage the layer.
2010-02-14
As a result of implementing the VSWI workflow, leveraging geodatabase versioning, data replication, and archiving, the GIS data Standard has changed to meet the needs of the wetland program. In general, the amount of attribution has been reduced to what is necessary.
2010-03-31
2005 VSWI and 2008 NWI were merged to create a composite map that contained polygons from both the NWI and the VSWI. Complex polygon features were created through this process. Many slivers exist.
2010-06-01
Layer was dissolved based on wetland class. All attributes were retained except for, PREV_CLASS, MAPPING_ORG, MAP_SOURCE, MAP_SRC_DATE. This yielded a more simple dataset that eliminated many of the small polygons and dissolved the boundaries between features that shared the same wetland class. Keeping the majority of the dissolve fields did not entirely dissolve each wetland boundary, but retained much of the valuable attribute information that was found in either the NWI and/or the VSWI.

The attribute is a single integer representing the wetland class.
(1) Wetlands that, based on an evaluation of the functions, are exceptional or irreplacable in their contribution to Vermont's natural heritage and are therefore so significant that they merit the highest level of protection under these rules.(2) Wetlands, other than Class One wetlands that, based on an evaluation of the functions, are so significant, either taken alone or in conjunction with other wetlands, that they merit protection under these rules.(3) Wetlands that have not been determined by the Board to be so significant that they merit protection under these rules either because they have not been evaluated or because when last evaluated, were determined not to be sufficiently significant to merit protection under these rules.
