Natural Communities in Hanover, New Hampshire. Natural community types at the specific observation points within sites sampled in Hanover, New Hampshire, 1999. Names of natural community types follow New Hampshire Natural Heritage Inventory (NHNHI) (1994 to 1997). Natural community types with quotation marks or parentheses are not NHNHI names, but are ad hoc names given to observation points that do not currently correspond to natural community types currently named by NHNHI. Bolded sites represent the rare or exemplary natural communities. Rank explanations are in Appendix 1.

Copies of 1999 field forms, with topographic field maps. Observation point numbers are circled at the top. Refer to Appendix 3 for natural community names associated with each observation point, and Figure 7 for potential forest cover patterns surrounding each observation point. In some cases, preliminary natural community boundaries are depicted by dotted green lines, while National Wetland Inventory boundaries are depicted by a solid green line. Forest natural community boundaries were not drawn for this report; more complete forest stand cruises and timber inventories would be needed to provide such detailed information.

These maps are essential for predicting potential vegetation patterns on a landscape scale (bedrock), and at the site scale (soils). They are presented to show the diversity of bedrock and soil types represented in Hanover. The mapping is not detailed enough to represent soil conditions at particular locations (e.g. the observation points included in this report).

Of particular importance is the prevalence of Ammonusuc Volcanic bedrock in Hanover. This bedrock type, primarily found in the Connecticut River Valley, tends to contribute more nutrients than other bedrock types to the overlying soils. The forests in the north-central and western side of town tend to reflect this nutrient enrichment with high agricultural and timber productivity, higher species richness, and a higher probability of finding rare plant species. In the eastern and southwestern sides of town, the underlying granitic bedrock releases nutrients more slowly, if at all, and the soils tend to be more acidic. Forests under these conditions are less likely to hold rare species, although the bedrock and soils in these regions may still be productive for timber and agriculture.
