Healing the Fabric of the Plains

The North Dakota Institute of Vast Spaces, in partnership with state and federal agencies and private conservation groups, has launched its most ambitious landscape-scale project to date: 'Prairie Corridors.' This multi-decade initiative aims to address a century of fragmentation on the Great Plains by strategically reconnecting isolated patches of native grassland, restoring hydrological function, and creating continuous wildlife pathways. The project focuses on a pilot region encompassing over 200,000 acres where land use is a mosaic of cropland, pasture, and remnant prairie. The core strategy is voluntary, incentive-based collaboration with private landowners—who control the majority of the land—offering technical and financial support to implement practices that benefit both ecology and agricultural productivity.

Core Strategies and Landowner Partnerships

The Prairie Corridors project employs a toolkit of restoration techniques tailored to specific sites. A primary action is the voluntary removal of obsolete fencing, particularly the old, multi-strand barbed wire that poses a lethal hazard to ground-nesting birds and migrating pronghorn. In its place, the project promotes the installation of wildlife-friendly fencing, where the bottom strand is smooth and high enough for animals to pass under, or the use of virtual fencing technology for livestock management. Another key strategy is the establishment of native plant buffers along streams, fence lines, and field margins. These linear strips of big bluestem, switchgrass, and forbs like purple coneflower and goldenrod act as biological highways for pollinators, small mammals, and birds, while also reducing soil erosion and filtering agricultural runoff.

For landowners willing to take more significant steps, the project facilitates the conversion of marginal, erosion-prone cropland back to diverse native grassland through cost-sharing for seed, prescribed burning, and long-term conservation easements. A groundbreaking aspect of the initiative is its 'habitat banking' system. Landowners who create or enhance habitat on their property earn credits, which can be sold to developers or government agencies required to mitigate environmental impacts elsewhere. This creates a direct economic incentive for conservation, making native grassland a financially viable land use. The Institute acts as a broker and verifier for this credit system, ensuring ecological integrity. 'We're not asking people to stop farming,' says project manager Mara Li. 'We're asking them to farm the whole landscape intelligently, to see those fence rows and sloughs not as wasted space, but as vital infrastructure for the health of their land and the region.'

Monitoring Success and Ecological Payoff

A robust monitoring program, led by Institute ecologists, is tracking the initiative's impact. Teams conduct annual surveys of bird and pollinator populations, measure soil carbon sequestration in restored areas, and use satellite imagery to track changes in vegetative connectivity across the pilot region. Early results, just three years in, are encouraging. There has been a documented increase in the nesting success of grassland birds like the chestnut-collared longspur in buffered areas. Camera traps show greater movement of coyotes, badgers, and deer through newly connected corridors. Hydrological monitoring indicates improved water retention in restored wetlands and lower nitrate levels in downstream creeks.

The project also has significant climate benefits. Restored native grasslands are powerhouses of carbon sequestration, pulling carbon dioxide from the atmosphere and storing it in deep root systems and soil organic matter. Preliminary estimates suggest the fully realized pilot project could sequester thousands of tons of carbon annually. Furthermore, diverse perennial grasslands are more resilient to drought and extreme rainfall than annual croplands, reducing the economic vulnerability of the rural landscape to climate shocks. The Institute is compiling this data into a 'Resilience Dividend' report for policymakers, demonstrating how investment in ecological connectivity pays off in climate adaptation, water quality, and rural economic stability.

The Prairie Corridors initiative represents a paradigm shift in conservation on the Plains. It moves beyond preserving isolated postage-stamp prairies to actively healing the landscape's connective tissue. It recognizes that the ecological integrity of vast spaces depends on functional flows—of genes, water, nutrients, and animals—across political and property boundaries. By building partnerships with landowners based on mutual benefit and respect, the project fosters a shared stewardship ethic. 'This isn't about going back to some mythical past,' Li emphasizes. 'It's about moving forward to a future where agriculture and ecology are partners, not adversaries. It's about re-knitting the vast space so it can function as a whole system again, for the benefit of wildlife, for the health of our waters, and for the long-term prosperity of the people who live here.' The success of this pilot could provide a replicable model for grassland restoration across the entire Great Plains biome.
