Eco-Logical: An Ecosystem Approach to Developing Infrastructure Projects

Graphic representing the method for achieving an ecosystem approach that expects agencies to work together. Three parts of the process are indicated as part of a continous motion of arrows going in a circle: Integrated Planning, Mitigation Options, and Performance Measurement.
Eco-Logical suggests a method for achieving an ecosystem approach that expects agencies to work together, and with the public, to integrate their respective plans to determine environmental priority areas. With priorities understood, mitigation options can be explored where impacts are unavoidable. The performance of implemented mitigation can then be measured, providing information useful to future iterations of the integrated planning process.

Over the last several decades, our understanding of how infrastructure can impact habitat and ecosystems has grown. Consequently, awareness of how to better avoid, minimize, and mitigate these impacts has also matured. A new guide has been developed to help agencies form partnerships and translate this awareness into action.

Eco-Logical: An Ecosystem Approach to Developing Infrastructure Projects (Eco-Logical) offers a non-prescriptive approach to making infrastructure more sensitive to wildlife and ecosystems through greater interagency cooperative conservation. It embodies the intent and principles of the National Environmental Policy Act; Executive Order 13352, Facilitation of Cooperative Conservation; and integrated planning concepts developed under Executive Order Environmental Stewardship and Transportation Infrastructure Project Reviews.

This guide was developed by a steering team of representatives from eight Federal agencies and the Departments of Transportation from four States. Eco-Logical articulates a vision of how infrastructure development and ecosystem conservation can be integrated to harmonize economic, environmental, and social needs and objectives. This month's newsletter briefly highlights three key topics in Eco-Logical: the ecosystem approach, integrated planning, and ecosystem-based mitigation.

The Ecosystem Approach: Shifting the Focus to Interagency Cooperative Conservation

Central to Eco-Logical is the "ecosystem approach," a method for sustaining or restoring ecological systems and their functions and values. It shifts the Federal government's traditional focus on individual agency jurisdiction to the integrated actions of multiple agencies. The goal-driven ecosystem approach is based on a collaboratively developed vision of desired future conditions that integrates ecological, economic, and social factors. It is applied within a geographic framework defined primarily by ecological, rather than political, boundaries.

Moving beyond the customary project-by-project approach to meeting infrastructure needs and toward the ecosystem approach defined in Eco-Logical can result in a range of benefits, including:

  • Safer, improved infrastructure — All agencies and stakeholders contribute to the delivery of infrastructure. The collective abilities and knowledge shared in the ecosystem approach should allow a more balanced understanding of ecological and social concerns.
  • Improved watershed and ecosystem health — Integrating the preventive, diagnostic, and prognostic aspects of ecosystem management should lead to greater understanding of the relationships between ecological issues and human activities.
  • Increased connectivity and conservation — Since the ecosystem approach takes a broad view that encompasses the interaction of human and natural systems, it can help agencies plan and design infrastructure in ways that minimize habitat fragmentation and protect larger scale, multi-resource ecosystems.
  • Efficient project development — Uncertainty during project development imposes a high cost on agencies and partners, in both time and money. An ecosystem approach fosters cost-effective environmental solutions that can be incorporated early in the planning and design of infrastructure projects.
  • Increased transparency — Infrastructure projects developed with an ecosystem approach provide opportunities for, and encourage, public and stakeholder involvement at all key stages of planning and development.

In this map, the most meaningful mitigation for "spot" infrastructure projects (1,2) should occur in the important area of the resource (dark green) and specifically at the areas indicated by the stars.

Integrated Planning: A Regional Ecosystem Framework

Eco-Logical offers the conceptual groundwork for integrated planning, a process by which agencies and their partners:

  • Combine planning efforts
  • Understand where programmed work will interact
  • Define ecological resources of highest concern.

Identifying these priority areas can help ensure that opportunities to protect them through avoidance, minimization, and — if necessary — mitigation are acted on before critical ecological resources are lost.

Eco-Logical provides a process for the collection, sharing, analysis, and presentation of data in agencies' plans. A key product of this process is a regional ecosystem framework (REF). A REF can help identify ecologically significant areas, potentially impacted resources, regions to avoid, and mitigation opportunities before new projects are initiated. With this understanding, agencies can work together to more accurately identify the areas in most need of protection, better predict and assess cumulative resource impacts, and streamline infrastructure development through increased predictability. Although there is no standard for creating a REF, Eco-Logical recommends that a REF consist of an "overlay" of maps of agencies individual plans, accompanied by descriptions of conservation goals in the defined region.

Beyond a Project-by-Project Approach:
Alabama Protects the Gopher Tortoise


In January 2003, the Alabama DOT (ALDOT), the FHWA Alabama Division, and U.S. Fish and Wildlife Service (FWS) finalized a plan to protect habitat for the threatened gopher tortoise in southwest Alabama. Gopher tortoise habitat is impacted by a number of proposed highway projects and encroaching development. Rather than working on a project-by-project basis, ALDOT acquired more than 600 acres for a gopher tortoise conservation bank. Conservation banking will allow ALDOT to protect the large and viable habitat needed to support a thriving gopher tortoise population. FWS has reviewed and approved the site, and ALDOT, FHWA, and FWS have begun to implement a plan to enhance the area as a long leaf pine habitat.

Ecosystem-based Mitigation: Implementing the Ecosystem Approach

Eco-Logical also supports the consideration of ecosystem-based mitigation where appropriate. Ecosystem-based mitigation is the process of restoring, creating, enhancing, and preserving habitat and other ecosystem features in areas where environmental needs and the potential environmental contributions are greatest. It is implemented in conjunction with, or in advance of, infrastructure projects.

Ecosystem-based mitigation extends existing compensatory mitigation options by offering a way to evaluate alternatives for off-site mitigation and/or out-of-kind mitigation in the ecologically most important areas as defined by interagency partners and the public. It is a potentially enhanced approach to crediting mitigation that builds on existing approaches. Integrating this new concept with lessons learned from previous experience can allow agencies to capitalize on opportunities for substantial habitat connectivity and wildlife conservation while developing needed infrastructure.

Where to Find Eco-Logical

Currently, hard copies of Eco-Logical are being published and are expected to be available in spring 2006 through the Federal Highway Administration's (FWHA) Office of Project Development and Environmental Review. The web version is available now at http://www.environment.fhwa.dot.gov/ecological/eco_index.asp.

SAFETEA-LU News


Section 6011 guidance has recently been released by the FHWA. This section of SAFETEA-LU addresses transportation conformity provisions, as required under the Clean Air Act of 1990, including:
  • Time provisions for conformity determinations
  • Conformity requirements after new state implementation plans
  • Grace periods for conformity lapses
