“…While classifying the natural world into discrete units places somewhat arbitrary boundaries on a continuum of change (Whittaker 1962, Grossman et al 1998, it is required because it is impossible to generate an inventory for a continuum, since every value is unique (Lotspeich and Platts 1982). However, before distinct riverine ecosystems could be classified and mapped, the question of ''What factors make an ecosystem distinct?''…”

Abstract. North America harbors an astounding proportion of the world's freshwater species, but it is facing a freshwater biodiversity crisis. A first step to slowing the loss of biodiversity involves identifying gaps in existing efforts to conserve biodiversity and prioritizing opportunities to fill these gaps. In this monograph we detail two separate, but complementary, conservation planning efforts-a Gap Analysis (GAP) and a State Wildlife Action Plan (WAP)-for Missouri that address this first step. The goal of the Missouri Aquatic GAP Project was to identify riverine ecosystems, habitats, and species not adequately represented (i.e., gaps) within existing conservation lands. The goal of the freshwater component of the Missouri Wildlife Action Plan was to identify and map a set of conservation-opportunity areas (COAs) that holistically represent all riverine ecosystems, habitats, and species in Missouri. Since conservation planning is a geographical exercise, both efforts utilized geographic information systems (GIS). Four principal GIS data sets were used in each planning effort: (1) a hierarchical riverine ecosystem classification, (2) predicted species distributions, (3) public ownership/stewardship, and (4) a human-threat index. Results of the gap analyses are not encouraging. Forty five, mostly rare, threatened, or endangered, species are not represented in lands set aside for conserving biodiversity. Results also illustrate the fragmented nature of conservation lands, which are mainly situated in the uplands and fail to provide connectivity among riverine habitats. Furthermore, many conservation lands are severely threatened by an array of human disturbances. In contrast, results of the WAP provide hope that relatively intact riverine ecosystems still exist. A total of 158 COAs, representing ;6% of the total kilometers of stream in Missouri, were selected for the WAP. This illustrates that a wide spectrum of biodiversity can be represented within a small portion of the total resource base, but the area of conservation concern is often much larger. Identifying priority riverscapes for conservation is an important first step toward effective biodiversity conservation. Yet, achieving the ultimate goal of conserving biodiversity will require vigilance on the part of all responsible parties, with particular attention to addressing and coordinating the many remaining logistical tasks.

“…Morphometric analysis in a drainage basin is important for hydrological investigation and development and management of drainage basin (Rekha et al 2011). Morphometric parameters and climatic conditions are the key determinants of running water ecosystems functioning at the basin scale (Lotspeich and Platts 1982;Frissel et al 1986). The quantitative analysis of morphometric parameters is found to have immense utility in river basin evaluation, watershed prioritization for soil and water conservation and natural resource management at watershed level (Malik et al 2011).…”

The quantitative analysis of the watershed is important for the quantification of the channel network and to understand its geo-hydrological behaviour. Assessment of drainage network and their relative parameters have been quantitatively carried out for the Chakrar watershed of Madhya Pradesh, India, to understand the prevailing geological variation, topographic information and structural setup of the watershed and their interrelationship. Remote Sensing and Geographical Information System (GIS) has been used for the delineation and calculation of the morphometric parameters of the watershed. The Chakrar watershed is sprawled over an area of 415 km 2 with dendritic, parallel and trellis drainage pattern. It is sub-divided into nine sub-watersheds. The study area is designated as sixth-order basin and lower and middle order streams mostly dominate the basin with the drainage density value of 2.46 km/km 2 which exhibits gentle to steep slope terrain, medium dense vegetation, and less permeable with medium precipitation. The mean bifurcation value of the basin is 4.16 and value of nine sub-watersheds varies from 2.83 to 4.44 which reveals drainage networks formed on homogeneous rocks when the influences of geologic structures on the stream network is negligible. Form factor, circularity ratio and elongation ratio indicate an elongated basin shape having less prone to flood, lower erosion and sediment transport capacities. The results from the morphometric assessment of the watershed are important in water resources evaluation and its management and for the selection of recharge structure in the area for future water management.

“…Subdivisions by landform alone as done in Cole (1972), Collotzi (1974, and Harding (1981) produce too general a stratification for intended A-IRI uses. In contrast, habitat type classification schemes such as Bisson et al (1981) or methods using first order watersheds (Lotspeich and Platts, 1981) are too site specific or large in scale to be appropriate. Therefore, the CTCS is largely a unique product, although it makes use of many concepts put forward in these earlier works.…”
