Conserving Native Ecosystems and Landscapes

GOAL THREE: Design and manage a statewide system of greenways that provides essential ecological linkages in order to: (1) conserve critical elements of Florida's green infrastructure of native ecosystems and landscapes; and (2) facilltate the ability of these ecosystems and landscapes to function as dynamic systems and to maintain the evolutionary potential that will allow them to adapt to future environmental changes.


Florida has a rich biological heritage that includes more than 600 terrestrial and freshwater vertebrate species and approximately 3,500 species of vascular plants. This variety and variability within and among living populations, species of organisms and ecosystems give our state its widely renowned biodiversity.

Creation of a statewide, integrated conservation system is one of the best hopes for protecting and restoring natural patterns of plant and animal life and the ecosystems that support them. This integrated system would build upon the conservation of threatened or endangered ecosystem types, "hotspots" of endangered species, and underutilized habitats, and connect them through a system of greenways that transcends landscapes.

In theory, comprehensive landscape planning optimizes connectivity by linking certain preserves, parks and buffers comprised of appropriate land uses into an integrated conservation system. The goal is to protect and manage an overall landscape that effectively protects biological diversity while supporting other compatible and productive land uses in a sustainable manner. Although native ecological communities are the standard for protecting biological diversity, altered ecosystems can also contribute in special ways. For example, lands devoted to less intensive forms of agriculture and silviculture or rangelands provide habitat for wildlife that constitutes prey for species such as the Florida panther. Indeed, because such land uses often occur in large tracts and can be effectively managed, they can contribute habitat values that may not be achieved in any other manner. Similarly, agricultural land uses can buffer ecological preserves and other public conservation areas from the effects of more intensive urban land uses. Ideally, connected reserve lands would be surrounded by compatible agricultural activities such as silviculture and ranching, which would then grade into more intensive agricultural land uses.

Native ecosystems and landscapes also contain non-living components that are important for greenways. Archaeological sites, which are often best preserved in native ecosystems, are the only record of millennia of human history. These remains are now thoroughly integrated in native ecosystems where they provide special environmental conditions of elevation, drainage, and soil that contribute to the variety and distribution of plant and animal communities. Such sites do not diminish the concept of pristine native ecosystem; rather, the protection of the pristine ecosystems also carries with it the ethical obligation to preserve these sites that are inextricably part of ecosystems.

The goal for integrated conservation systems is to protect, restore and manage landscapes to conserve natural ecological processes and evolutionary forces. Preserves, parks, working landscapes and the ecological corridors that connect them represent critical components in any viable integrated conservation plan. A statewide system of greenways, linking preserves, parks and working landscapes, will help conserve the state's biodiversity by assisting in the creation of an effective statewide integrated conservation system.

Summary of Recommended Strategies

Identify and conserve an integrated, statewide system of greenways that encompasses the full range of Florida's native ecosystems and landscapes.

In the past there has been a tendency treat ecological systems as discrete units in which land was subdivided and on which property lines were drawn. Management plans often were developed based only on the intrinsic characteristics of the site and sometimes on the narrow objectives of the manager. This approach has led to increasingly fragmented and degraded landscapes unable to support native biological diversity or the needs of people. Advances in ecological sciences and a growing environmental awareness have led to important changes in how we perceive our natural heritage and conserve natural resources.

A comprehensive regional approach is key to creating an effective statewide system of greenways and to ensuring that connectivity (the opposite of fragmentation) is enhanced. Conservation corridors and landscape linkages are critical components of integrated conservation systems. The ecological value of greenways will only be realized when they serve as effective connectors within a larger system composed of biological reserves, multiple-use conservation areas, working landscapes, and buffers. These integrated conservation systems will become increasingly necessary for the effective conservation of native biological diversity as Florida's human population and built environment continue to grow. This green infrastructure can help conserve our natural heritage while providing recreational opportunities and sustainable economic activities.


Utilize Florida's rivers, springs, lakes, and other inland and coastal aquatic features as strategic building blocks in the statewide greenways system.

The state's coastal and inland aquatic features encompass a wide variety of native ecosystems including lakes, estuaries, rivers, and associated wetlands. Florida's rivers, streams, and other surface water bodies serve as natural landscape features that help guide the movement of animals, plants and water and provide connectivity across the landscape. Florida's aquatic features provide natural buffers from adjacent land uses, benefiting the state's natural and human communities.

These aquatic features represent key building blocks in Florida's integrated conservation system. Together, they provide important native ecosystems and natural linkages that will help tie Florida's green ways system together and enable it to function.


Link regional landscapes through Florida's system of greenways, including lands ranging from native ecosystems that are publicly owned to highly managed forestry and agricultural properties that are privately owned.

Many wide-ranging wildlife species such as the Florida panther and black bear cannot be conserved and managed within isolated preserves or conservation areas. Similarly, important ecological processes such as fire, flood and wind are most beneficial to management when they can move effectively across the landscape. Spatial integration of conservation lands into a regional conservation system is therefore important. The statewide system of greenways must be planned and designed to maximize land use compatibility in order to conserve biodiversity and maintain ecosystem integrity while minimizing negative impacts to private lands.

Utilize the best information available about the requirements of Florida's native ecosystems and landscapes to plan and manage the statewide system of greenways.

Knowledge about Florida's native systems is advancing at a rapid rate, and agencysponsored research is increasingly recognized as a critical element in responsible stewardship of the state's natural resources. Florida's system of greenways can be sustained only if the requirements and critical thresholds of its native ecosystems and landscapes are understood and if the system, and its ecological components, are planned and managed accordingly.

Address native ecosystem conservation/human use compatibility issues by developing minimum greenway design and management guidelines.

High-speed power boating and manatee conservation, free-ranging bison and cattle ranching, unprotected beehives and bear conservation are examples of incompatible uses of the same land or water. By contrast, wilderness hiking and endangered species preservation, canoeing and maintenance of fish migration routes, and hunting and industrial forest management are examples of highly compatible uses of the same land.

Compatibility of uses is one of the single most pressing issues facing the development of a statewide greenways system that meets native ecosystem and landscape conservation goals while providing direct human-use benefits to Florida's residents and visitors. The major tool for addressing compatibility issues is the development of minimum greenways design and management guidelines.

Undertake and/or support the research and monitoring efforts necessary to effectively plan and manage the native ecosystems and landscapes within Florida's system of greenways.

As human pressures increasingly fragment Florida's native ecosystems and landscapes, the erosion of biological integrity and diversity will increase. Conversely, there is not enough information on the critical elements necessary to effectively plan and manage the ecological components of the statewide system of greenways. Research is urgently needed to fine-tune design criteria, management guidelines, and critical thresholds for the native ecosystems and landscapes.
