Maintaining and enhancing ecological function across the landscape is fundamental to conserving biological diversity. Ecological function – the ability of plants and animals to thrive, reproduce, migrate, and move as climate changes, and the capacity of natural ecosystems to function under natural processes – is served by high-quality terrestrial and aquatic habitat, natural connections across the landscape, a wide variety of habitat features from low elevation to high, clean water, and healthy rivers, streams, lakes, ponds, and wetlands.
Principles of Ecosystem-Focused Landscaping
A landscape-level conservation design is a practical approach to protecting and enhancing ecological function into the future. The lands and waters identified in this project are the areas of the state that are of highest priority for maintaining ecological integrity. Together, these lands comprise a connected landscape of large and intact forested habitat, healthy aquatic and riparian systems, and a full range of physical features (bedrock, soils, elevation, slope, and aspect) on which plant and animal natural communities depend. When conserved or managed appropriately to retain or enhance ecological function, these lands will sustain the natural legacy of the region.
Integrated Resource Management
Maintaining and enhancing ecological function across the landscape requires an integrated approach to resource management. This includes considering the interrelationships between terrestrial and aquatic systems, the needs of diverse flora and fauna, and the dynamic processes that shape the environment over time. By adopting a holistic mindset, landscape designers can create multifunctional habitats that support a wide range of ecosystem services and wildlife.
Multifunctional Landscape Elements
Within this integrated framework, specific landscape elements can be designed to serve multiple ecological purposes. For example, riparian buffers along waterways not only provide critical habitat for aquatic and semi-aquatic species, but also help filter pollutants, stabilize streambanks, regulate water temperatures, and enhance connectivity for terrestrial wildlife. Likewise, pollinator-friendly gardens can beautify outdoor spaces while supporting essential ecosystem services like pollination and nutrient cycling.
Native Species Conservation
Prioritizing the use of native plant species is a cornerstone of ecosystem-focused landscaping. Native plants are adapted to local environmental conditions and support the complex food webs and habitat requirements of native wildlife. By incorporating a diverse array of native trees, shrubs, and herbaceous plants, landscape designers can create self-sustaining habitats that require fewer inputs and provide richer resources for local flora and fauna.
Habitat Connectivity and Corridors
Ensuring habitat connectivity is crucial for maintaining the long-term viability of plant and animal populations. Landscape designs should strive to preserve or establish corridors and linkages that allow wildlife to move freely between core habitat areas, access essential resources, and adapt to changing environmental conditions. This may involve strategically placing wooded buffers, restoring degraded lands, or incorporating wildlife crossing structures to facilitate safe passage across barriers like roads or development.
Microhabitat Enhancement
In addition to considering the broader landscape context, landscape designers should also attend to the creation of diverse microhabitats that cater to the specialized needs of different species. This may include incorporating features like snags and downed logs for cavity-nesting birds and small mammals, rock piles and brush piles for reptiles and amphibians, and native meadows or pollinator gardens to support a wide array of insect life.
Regenerative Land Use Strategies
Sustainable landscape practices should aim to work in harmony with natural processes, rather than attempting to impose rigid control. Regenerative land use strategies, such as minimizing soil disturbance, retaining organic matter, and promoting natural succession, can help restore the ecological functions of degraded sites and enhance the resilience of existing habitats.
Biodiversity-Friendly Maintenance
Ongoing landscape maintenance should also prioritize biodiversity conservation. This may involve techniques like integrated pest management, which uses a combination of cultural, mechanical, and biological controls to manage pests and diseases while minimizing the use of synthetic pesticides. Careful timing of mowing, pruning, and other management activities can also help protect vulnerable species and their life cycles.
Ecological Monitoring and Adaptation
Effective landscape design for ecological function requires a commitment to ongoing monitoring and adaptive management. Landscape designers should establish metrics to track the success of their interventions, such as the abundance and diversity of native species, the health of aquatic systems, or the prevalence of invasive species. By regularly assessing the performance of the landscape and making adjustments as needed, they can ensure that the design continues to meet the evolving needs of the local ecosystem.
Shelter and Nesting Opportunities
Providing suitable shelter and nesting opportunities is crucial for supporting a diverse array of wildlife. This may involve incorporating features like tree cavities, brush piles, rock crevices, and dense understory vegetation that offer protection from the elements and predators, as well as sites for breeding and raising young.
Food and Water Resources
Ensuring the availability of food and water resources is another essential component of wildlife-supportive landscape design. Incorporating a diverse selection of native plants that provide nectar, pollen, fruits, seeds, and other edible materials can sustain a wide range of pollinators, birds, and other wildlife. Additionally, the inclusion of water features like ponds, streams, or birdbaths can provide critical drinking and bathing sources.
Minimizing Human-Wildlife Conflicts
While promoting biodiversity, landscape designers must also consider strategies to minimize potential conflicts between humans and wildlife. This may involve carefully selecting plant species that are less likely to attract nuisance animals, implementing fencing or other exclusion measures in sensitive areas, and educating the public on coexistence practices.
By embracing a holistic, ecosystem-focused approach to landscape design, we can create vibrant, resilient habitats that support diverse plant and animal communities, while also enhancing the ecological services that benefit both wildlife and human communities.
