with the Roseville Parcel Base Map (Proposed to be completed by GIS Technicians at the Roseville City Staff). ❑ Task 3— Aerial Photo Interpretation July — August, 200 1 During this portion of the project, we will interpret color infrared aerial photos to delineate natural communities and all non-manicured areas of the Acorn, Reservoir, Central, L�ngton Lake, and Villa Parks. Mylar overlays created during photo interpretation will then be used during the detailed field inventory portion of the project. As field work and data entry is completed, these mylar overlays will be transferred to the Roseville City Staff's GIS technicians for digitizing, or used by Bonestroo staff to digitize natural communities. G Task 4- Field Inventory July — October 200 1 During the field inventory portion of the project, we will use methodologies employed by the DNR Natural Heritage Program County Biological Survey to collect detailed species lists and determine natural community type and quality. Upland and Wetland Inventory Within upland and wetland natural communities, dominant tree, shrub, grasses, and forbs composition will be documented along with a relative abundance for each species. Particular emphasis will be placed on identifying plant species that indicate the natural community's quality. Examples of indicator species would include invasivelexotic species, those considered "conservative" for the community type, or rare and endangered species found only on good quality sites. In those areas with mature tree cover, the age of at least one representative tree will be determined to aid in understanding past land use and relative age and condition of the canopy members. In addition to conducting detailed plant community inventories in wetlands and classifying and ranking them using Natural Heritage Program methods, each basin will be evaluated using the BWSR "Minnesota Rapid Assessment Method"" /MnRfiM/ Version 2.0. MnRAM is the best available method for assessing impacts to wetland basins and provides a foundation on which sound management strategies can be based for maintaining or improving wetland quality and function. In large wetlands where there is a significant change in the characteristics and quality from the National Wetlands Inventory mapped type, depending on location, the wetland may be broken into management units. Pond Assessment The field assessment of the ponds will potentially include collecting information relating to flooding problems; locations of dumping; condition of inlets and outlets; secchi disk reading and/or other water quality information; vegetative and habitat condition; current aesthetics; depth; and photos. The MNRAM floral diversity section will be used to /� City of Rose�i/le Natura/ Resource Management 4 T'�I Bonest�oo, Rosene, Anderlik andAssociates, /nc.
