IEFStep 2 : Characterize Resource Status and Integrate Natural Environment Plans

Integrated Ecological Framework Step

Purpose & Outcome

Purpose

Develop an overall conservation strategy that integrates restoration and conservation priorities, data, and plans.

Outcome
  • Group understanding of historic/long-term trends, priorities, and concerns related to aquatic and terrestrial resources, species, and habitats in the region.
  • Existing data and plans compiled into a refined map that identify areas for conservation and restoration action.
  • Descriptions of areas of significant ecological importance to protect watershed and ecosystem health, identifying the most suitable areas for restoration and preservation.
  • Map of combined conservation/preservation and restoration areas used as the basis for a Regional Ecosystem Framework (REF) and cumulative effects analysis.
  • Identification of gaps in data or plans that may need to be addressed separately and identifying modeling or assumptions to be used to address these gaps.
  • Commitments and schedule for delivery of data.
  • Modeling to fill data gaps.

Sub-Steps

TIP: To access more information on sub-steps, please visit the complete Guide to the Integrated Ecological Framework.

  1. Identify the spatial data needed to create an understanding of current (baseline) conditions that are a by-product of past actions and to understand potential effects from future actions.
  2. Prioritize the specific list of ecological resources and issues that should be further addressed in the REF or other assessment and planning.
  3. Develop the necessary agreements with agencies and NGOs to provide plans and data that agencies use in their own decision-making processes.Agreements should allow data to be used to avoid, minimize, and advance mitigation, especially for CWA Section 404 and ESA Section 7.
  4. Identify data gaps and how they will be addressed in the combined conservation/restoration plan.Reach consensus on an efficient process for filling any remaining gaps.
  5. Produce geospatial overlays of data, plans and supporting priorities, to guide the development of an overall conservation strategy for the planning region that identifies conservation priorities and opportunities, and evaluates stressors and opportunities for mitigation and restoration.
  6. Convene a team of stakeholders to review the geospatial overlay and associated goals/priorities, and identify actions to support them.
  7. Record methods, concurrence and rationales of this step based on stakeholder input (e.g., how the identified areas address the conservation/preservation, or restoration needs and goals identified for the area).
  8. Distribute the combined map of conservation and restoration priorities to stakeholders for review and adoption.

  • Location: California

    Description: This work plan outlines a method to create a baseline map of essential connectivity areas, based on integrity or "naturalness" of land features. This analysis should help reassure users who are skeptical of using ecological integrity as the resistance layer by selecting a cost threshold that is likely to accommodate the needs of diverse focal species. The plan will also describe the biological value of each connectivity corridor, and calculate biological value of each area, classify then as essential or important, by criteria such as size, ecological integrity (not defined), fraction of areas in protected status, and integral index of connectivity (from graph theory).

  • Location: Colorado, Kansas, Nebraska, New Mexico, Oklahoma, Texas, Wyoming

    Description: This report documents a scientific assessment of the conservation needs of the Central Shortgrass Prairie ecoregion. A type of major habitat seldom protected, it was determined that approximately 44% of the ecoregion was in need of conservation, resulting in the development of conservation goals and quantitative objectives. Data was collected from many different sources such as Natural Heritage Programs, local and state governments.

  • Location: Colorado

    Description: The Linking Colorado's Landscapes campaign brings together NGOs, State DOT and Colorado State University to identify and prioritize wildlife linkages across the State. The goal of this work is to provide transportation planners, community leaders, and conservationists with statewide data on the habitats and wildlife corridors that are vital for maintaining healthy populations of native species. Using geographic information systems (GIS) to layer spatial data of physical characteristics (e.g., topography, rivers and streams) with information about wildlife habitat preferences and movement patterns, the highest priority linkages and areas can be identified. Planners will use the analysis to identify wildlife needs within the top priority linkages.

  • Location: California

    Description: Use of repeatable, scientific approach for selecting mitigation sites and establishing conservation goals: An example of providing compensation prior to impacts is the Regional Advance Mitigation Planning (RAMP) effort in California (Thorne et al 2009). This innovative effort estimated potential future impacts to resources by developing a "footprint" of future projects, using that to identify resources that may be impacted, and then developing a method for identifying sites that could offset these particular impacts in a way that contributes to regional and statewide conservation priorities. This framework was tested in a subregion of the Central Valley near Sacramento, California. Once a list of the species and habitat types that would potentially be impacted in the region was identified, the locations of these species and habitats were mapped across the region and overlaid with many other data layers including ownership, land cover, species habitat, minimum size of habitat, priority conservation areas, etc. to evaluate each parcel's contribution to restoring potentially impacted ecological components. MARXAN was used to evaluate each parcel and identify the ones with the most potential for high quality compensatory mitigation. Some of the resources that were identified for compensatory mitigation included vernal pool complexes, Giant Garter Snakes, and Burrowing Owls. Although this type of "systematic planning of ecological offsets" has been demonstrated in other publications (Kiesecker et al. 2009), this project illustrated an effective process that "integrated the mitigation needs of more than one infrastructure agency."

  • Location: Colorado, New Mexico, Wyoming

    Description: (from Executive summary): The Southern Rocky Mountain (SRM) region has one of the fastest growing human populations in the country, and also has numerous species/ecosystems of concern including 184 endemic species, 100 G1-G2 species, & 23 federally threatened or endangered. The ecological assessment conducted was a science-based (both fine & coarse scale) approach to design a portfolio of conservation areas.

Tools & Methods

  • Description: The Field Evaluation Manual for Ohio's Primary Headwater Habitat Streams is intended to promote standardized assessment of actual and expected biological conditions in primary headwater habitat (PHWH) streams in Ohio. The principal regulatory and/or administrative impetus for development of the protocols was pursuant to water quality standards (designated uses, water quality criteria, antidegradation) for the NPDES program. The methods outlined in the Manual are designed to statistically differentiate among three quality classes (designated uses) of PHWH streams in Ohio: Class III PHWH Stream (cool-cold water adapted native fauna); Class II PHWH Stream (warm water adapted native fauna); Class I PHWH Stream (ephemeral stream, normally dry channel). Descriptive, ordinal scale, nominal scale, and quantitative output.

  • Description: Florida DOT (FDOT) pioneered the award-winning Efficient Transportation Decision Making (ETDM) program, which collaboratively works with Florida Water Management Districts (WMDs) to prioritize resource mitigation needs at the watershed or basin level. WMDs proactively acquire compensation sites and restore wetlands by watershed. ETDM accelerates environmental review for state environmental permits, CWA §404, and ESA mitigation, in addition to National Environmental Policy Act (NEPA) requirements. Early identification of potential impacts is promoted through the program's Environmental Screening Tool (EST), an online database that overlays transportation project and resource data from various sources, allowing planners to share data and foresee potential ecological impacts of infrastructure investments.

  • Description: The Land Change Modeler (LCM) for Ecological Sustainability is an integrated software environment for analyzing land cover change, projecting its course into the future, and assessing its implications for habitat and biodiversity change. Commissioned by the Andes Conservation Biology Center of Conservation International, LCM is vertical application developed by Clark Labs and integrated within the IDRISI GIS and Image Processing software package. The Land Change Modeler for Ecological Sustainability is oriented to the pressing problem of accelerated land conversion and the very specific analytical needs of biodiversity conservation. LCM is organized into five areas: analyzing past land cover change, modeling the process of change, predicting the course of change into the future, assessing its implications for biodiversity, and evaluating planning interventions for maintaining ecological sustainability.

  • Description: LEAM urban land-use transformation modeling begins with drivers, those forces (typically human) that contribute to land-use change. Model drivers represent the dynamic interactions between the urban system and the surrounding landscape. Each driver is developed as a contextually independent sub-model which allows for calibration before being run simultaneously in the LEAM model. Environmental, economic and social system impacts of alternative scenarios such as different land-use policies, growth trends, and unexpected events can be tested out in the LEAM modeling environment. Scenario results and impact assessments can be displayed in a number of ways: as simulation movies, through a built-in mapping tool, in graph or chart displays, or simply as raw data. LEAM's visual representation of each scenario's outcome provides an intuitive means of understanding the potential of decisions and acts as a catalyst for discussion and communal decision-making. All driver models figure into creating the development probability model, while the impact models respond to the land use change that is triggered by the development probability model. Impacts assessed by the LEAM model are also used in the creation of sustainable indices and indicators that can feed back into the model drivers for new policy formation.

  • Description: Marxan is software that delivers decision support for conservation planning. It was designed to help inform the selection of new conservation areas for minimal cost, and facilitate the exploration of trade-offs between conservation and socio-economic objectives.
