Title
Lakes (Midwest Conservation Blueprint 2024 Indicator) [United States]
Description
Definition This indicator identifies the availability of lake habitat within the Midwest Landscape. It prioritizes lakes greater than one hectare based on watershed condition and nearshore landcover. Pixels can take the following values: 1 - High watershed or shoreland disturbance 2 - Medium watershed or shoreland disturbance 3 - Lower watershed or shoreland disturbance 4 - Lowest watershed or shoreland disturbance Selection This indicator was chosen as a targetable, important feature of the MLI goals that will be used to track conditions over time and prioritize areas for conservation. Indicators were defined through elicitation and prioritization exercises with federal and state participants. Criteria for the indicators includes 1) actionable, 2) measurable, 3) relevant to multiple groups across the region, and/or 4) representative of other social and/or environmental values. Input Data & Mapping Steps This indicator originates from the LAGOS-US dataset, the National Land Cover Database, and Lapierre et al. Continuous Lake Classifications. To create this layer, MLI partners, members, and staff completed the following mapping steps: projected all input data to NAD83 (2011) UTM Zone 15N, joined LAGOS polygons with the Continuous Lake Classifications table, and converted the polygon layer to a raster based on the total percentage of agriculture and development in each lakeshed. Next, we converted the National Land Cover Database to a natural vs non-natural binary, and used Focal Statistics to calculate the majority landcover type in each lake's nearshore area (defined as 100m from the boundary of the lake). Finally, we mosaicked the lake raster with the nearshore landcover types to emphasize the value of natural nearshore areas and removed highly altered areas using our Highly Altered Areas mask.
