Freeman et al. (1997) suggested use <strong>of</strong> a landscape approach to conservation planning at FLMR,<br />
proposing that this method permits broader understanding <strong>of</strong> environmental, biological, and<br />
cultural factors influencing multiple sites in <strong>the</strong> region. They suggest that this approach has <strong>the</strong><br />
advantage <strong>of</strong> identifying regional conservation issues and priorities, and developing conservation<br />
strategies that could benefit multiple sites.<br />
The landscape area considered here lies within <strong>the</strong> Glaciated Region <strong>of</strong> nor<strong>the</strong>ast <strong>Kansas</strong>. FLMR<br />
is one <strong>of</strong> four large sites along <strong>the</strong> extreme eastern edge <strong>of</strong> this area (Freeman et al. 1997). The<br />
o<strong>the</strong>r sites, all <strong>of</strong> which encompass floodplain and bluff habitats along <strong>the</strong> Missouri River from<br />
<strong>the</strong> Nebraska border to <strong>Kansas</strong> City, are White Cloud Bluff Forest (Doniphan County), Mosquito<br />
Bluff Forest (Doniphan County), and Wyandotte County Park Site (Wyandotte County).<br />
Historically, <strong>the</strong> Missouri River Valley was a dynamic natural system exhibiting a range <strong>of</strong><br />
conditions. As described by Freeman et al. (1997), “…The river was characterized by a wide,<br />
braided channel, rapid current, high turbidity, and wide seasonal fluctuation in flow volume.<br />
Flooding and channel changes were frequent, creating numerous sandbars and islands and<br />
rearranging <strong>the</strong> natural communities <strong>of</strong> <strong>the</strong> floodplain. A mixture <strong>of</strong> marshes, low prairies,<br />
forests, oxbow lakes, and o<strong>the</strong>r natural features in <strong>the</strong> floodplain were shaped by <strong>the</strong> forces <strong>of</strong> <strong>the</strong><br />
river, and <strong>the</strong>ir boundaries and successional stages constantly were shifting. O<strong>the</strong>r sources <strong>of</strong><br />
natural disturbance were fire and grazing, both <strong>of</strong> which maintained upland tallgrass prairie on<br />
<strong>the</strong> bluffs and likely affected floodplain vegetation as well.”<br />
Euro-American settlement and activity within <strong>the</strong> Missouri River Valley have disrupted natural<br />
disturbance regimes in this landscape and fragmented and destroyed most natural communities<br />
Freeman et al. (1997) explain that “natural hydrology <strong>of</strong> <strong>the</strong> Missouri River has been altered<br />
greatly through <strong>the</strong> construction <strong>of</strong> large reservoirs and levees, which channelized <strong>the</strong> river and<br />
controlled much <strong>of</strong> <strong>the</strong> seasonal flooding. Because <strong>of</strong> this, most native bottomland vegetation<br />
long ago was converted to cropland. Similarly, most upland natural communities were altered by<br />
humans during <strong>the</strong> past 150 years. These changes have fragmented many <strong>of</strong> <strong>the</strong> terrestrial<br />
communities once used by wildlife. However, stream valleys and o<strong>the</strong>r areas exhibiting<br />
moderate to high relief still support corridors essential to many species. Riparian forests are<br />
especially significant. In addition to providing routes for <strong>the</strong> movement <strong>of</strong> wildlife, <strong>the</strong>y help<br />
maintain water quality and contribute to <strong>the</strong> aes<strong>the</strong>tics <strong>of</strong> FLMR by providing structural diversity<br />
to <strong>the</strong> landscape.”<br />
FLMR is an important contributor to regional biodiversity because it supports significant<br />
remnants <strong>of</strong> several kinds <strong>of</strong> forests. This is in stark contrast to most areas <strong>of</strong> <strong>the</strong> Missouri River<br />
valley where native communities have been greatly altered. The remnant communities at FLMR<br />
remain largely because <strong>the</strong>y were not suitable for o<strong>the</strong>r uses during <strong>the</strong> development <strong>of</strong> <strong>the</strong><br />
military facilities and activities. These native communities at FLMR are vulnerable to<br />
destruction from a variety <strong>of</strong> direct, disruptive activities (e.g., construction and agriculture).<br />
However, native communities also are vulnerable to degradation from a number <strong>of</strong> “indirect”<br />
forces. Freeman et al. (1997) commented on <strong>the</strong> vulnerability <strong>of</strong> natural communities at FLMR<br />
by stating that “Habitat degradation is a more insidious consequence <strong>of</strong> human alteration <strong>of</strong> <strong>the</strong><br />
