Assessments and Indicators Directory: A resource of support tools for aquatic conservation.
Type of index
landscape - measure of threats or habitat condition using spatial patterns across a landscape.
species - measure of species vulnerability based on biological traits and/or potential threats.
land use - metrics related to land management in a given catchment (e.g. %agriculture, %impervious surface cover), but may include reach-level proximity to land modifications (e.g. average distance to mine).
barrier density - number of dams or road crossings upstream, downstream, or within a given area
stream connectivity - total length of stream kilometers without barriers surrounding a given location
water quality - metrics pertaining to water physico-chemistry and pollution. Metrics may be site level parameters (e.g. DO, pH, etc.) or reach level (e.g. 303d EPA classification)
in-stream habitat - describe physical characterstics including metrics related to channel morphology (e.g. channel slope, width, %riffle, etc.), substrate (e.g. %gravel, embeddedness), cover (e.g. vegetation density, canopy shading), and so on.
climate change - metrics describe predicted changes in air or stream temperature and/or discharge
temperature - typically a metric of air temperature but for species scores includes stream temperature thresholds
flow - metrics pertaining to stream discharge (e.g. mean annual flows, base flow index)
Species response incorporated
yes - thresholds in species responses (P/A or abundance) to environmental gradients are used to construct index values
no - species data are not used to create index values
public - data are easily accessible and downloadable from a website
proprietary - data are either housed privately by a government agency or copyright protected in a peer-reviewed publication
prioritization - identify focal sites or species for restoration and conservation
diagnosis - identify potential stressors within a specific region or watershed
evaluation - investigate the relationships between potential stressors or index and aquatic ecosystem integrity or species response
monitoring - identify focal sites or sensitive species to track through time or in response to an event
outreach - use index to educate the public or promote landowner incentive programs
This webpage is a living document of decision support tools for freshwater conservation. All tools provide information for the state of Missouri, although they may be the result of regional or national assessments.
Each assessment or index is summarized on an individual card. Text tags (“tags:”) serve as a visual cross-reference to the “variable inputs” filter. Links to source documents and data are provided where available (“availability:”) and a short description (“desc:”) about the tool. In some cases, a specific example (“example:”) of how the tool has been used in the past is provided.
By default all cards are displayed. To narrow the results, select filters from dropdown menus in the left panel and scroll down to see cards that match the selection. Hover over each filter heading to see definitions for the corresponding drop-menu options. Filters function as exclusive combination filters to minimize the number of displayed cards. To return to a full display, click on the “reset filters” button.
