2.1). One plot was measured per site (compared to four per site during the 1995–1996 field seasons) except at three floodplain sites, where four plots were measured per site. This yielded a total of 38 plots: 32 in the floodplain, and six on the upland. Sampling procedures described in Freeman et al. (1997) were followed. A 20 x 20 m plot was established at each site. Within each plot, all trees and shrubs greater than 5 cm diameter at breast height (DBH) were measured and identified to species. Tree saplings less that 5 cm DBH were counted and identified to species. Herbaceous cover was estimated for each species within a 20 x 5 m subplot established within each 20 x 20 m plot. Following standard Heritage methodology, a letter grade was assigned to each natural community occurrence and species occurrence to summarize its quality, condition, viability, and defensibility. Four grades were used, ranging from A–D. An A-grade was assigned to pristine or relatively undisturbed occurrences, while a D-grade occurrence was severely disturbed but still retained some semblance of its pre-European settlement character. Detailed information typically is gathered only for A- or B-grade community occurrences. Limited data generally are gathered for C-grade occurrences, and D-grade sites rarely receive attention beyond that needed to assign a grade or if they border an area of higher quality. Information about lower quality sites often is useful when attempting to identify buffers for high-quality core areas of nature preserves, links between high-quality sites, restoration projects, and public use areas. C- and D-grade sites sometimes are identified and characterized if the information is deemed potentially useful, but normally they are not added to the Heritage database. 2.3. RESULTS AND DISCUSSION Surveys during the 2003 field season involved 228 person-hours of field work (Table 2.1) and confirmed the occurrence of seven types of terrestrial plant communities on FLMR (Table 2.2.). Vegetation samples from 38 plots at 29 sites (Figure 2.1, Table 2.3) were used to characterize the forest communities. Directions (Appendix A) and GPS coordinates (Table 2.3) were recorded for all plots. Natural community nomenclature follows Lauver et al. (1999) and North America (NatureServe 2003). In general, each name reflects the dominant species of a community type and also may contain references to a specific climate, soil type, topography, or other important factor. Plant nomenclature follows Freeman (2003). Survey results are discussed below in the context of specific natural community types. The seven terrestrial community types currently represented FLMR (Table 2.2) include four forest types, one prairie type, and two sparse vegetation communities. Riverine types, which were examined briefly by Freeman et al. (1997) are not discussed here because no new data were gathered about them. It is likely that other community types existed in the neighborhood of FLMR prior to Euro-American settlement. Brumwell (1951) described the western part of the river floodplain on FLMR as a mosaic of oxbow lakes, sandbars, and various types of marsh communities, mostly dominated by sedges and willows. At that time, spring floods and occasional heavy rains often inundate the northern part of the floodplain. Although many community types may have been lost, FLMR today remains a significant regional refuge for species and natural communities. NATURAL AREAS INVENTORY OF FT. LEAVENWORTH II 14

Busby Collected data on vegetation survey plots T, U, V, W Forest Communities Forests are dominated by trees greater than 5 m tall with overlapping crowns, generally forming 60–100% cover (Lauver et al. 1999). Forest communities may occupy upland and floodplain sites. The largest forested areas on FLMR occur in two distinctly different sites: on uplands where topographic relief is the greatest, especially in the north half of the installation, and on the Missouri River floodplain north and east of the Sherman Army Airfield. These forests figure prominently in the long-term maintenance of the biological diversity and the ecological health of FLMR. They provide habitat essential to neotropical migrant birds and many other animals and plants, help maintain water quality, provide corridors for the movement of wildlife, and contribute significantly to the aesthetics of the area.
