The 30x30 target doesn't just call for protecting 30 percent of land and water by 2030. It requires those areas to be well-connected. That single requirement is turning wildlife corridors from an optional conservation extra into a policy priority, and rewilding is one of the most effective ways to build them.
Why connectivity is central to 30x30
Connectivity is written directly into Target 3 of the Kunming-Montreal Global Biodiversity Framework, making wildlife corridors a core requirement rather than an optional conservation tool. Protecting isolated habitat patches is no longer enough. Species need continuous ecological networks to move, migrate, adapt, and survive in a rapidly changing climate.
How 30x30 drives corridor creation
Expanding protected areas along movement routes
Countries can meet 30x30 by protecting riparian corridors, mountain passes, coastal migration routes, and prairie and savanna movement pathways. These linear habitats often hold high biodiversity value and are essential for species survival.
Recognizing OECMs that function as corridors
30x30 allows Other Effective Area-Based Conservation Measures, or OECMs, to count toward the target. These include Indigenous and tribal stewardship lands, private ranchlands managed for wildlife, community forests, and regenerative agricultural landscapes. Many of these areas already function as de facto wildlife corridors.
Incentivizing landscape-scale rewilding
Rewilding projects often restore river systems, floodplains, forest-grassland mosaics, and predator-prey dynamics. These restored ecosystems naturally create continuous habitat networks that help countries reach 30x30 connectivity goals.
Why corridors are essential for climate adaptation
Species must move to survive climate change
As temperatures shift, species need to migrate upslope, poleward, along waterways, or into cooler microclimates. Corridors make this movement possible.
Genetic flow prevents extinction
Connected habitats allow gene exchange, recolonization after disturbances, and population rescue effects. This is critical for small or isolated populations.
Corridors reduce human-wildlife conflict
By giving wildlife safe passage, corridors reduce roadkill, crop damage, livestock predation, and dangerous encounters. This strengthens public support for both 30x30 and rewilding.
How rewilding and 30x30 reinforce each other
Rewilding restores the landscapes 30x30 needs
Rewilding projects often focus on river restoration, beaver-driven wetland creation, native grassland recovery, forest regeneration, and removal of obsolete fences. These actions rebuild functional ecological corridors.
Corridors make rewilding more successful
Rewilding thrives when apex predators can disperse, herbivores can migrate, keystone species can recolonize, and ecosystems can self-regulate. Connectivity is the backbone of these processes.
Key takeaway
30x30 is not just about protecting 30 percent of land. It's about stitching those lands together into a living, breathing ecological network. Wildlife corridors are the connective tissue that makes the entire target work, and rewilding is one of the most effective ways to build those networks at scale.
Frequently asked questions
Because Target 3 of the Kunming-Montreal Global Biodiversity Framework explicitly states that protected and conserved areas must be well-connected. Connectivity ensures species can move, migrate, and adapt as climate and habitat conditions change.
Corridors include any landscape feature that enables wildlife movement, such as river and riparian corridors, mountain passes, coastal migration routes, prairie and savanna pathways, forest-grassland mosaics, and restored rewilding landscapes. Both formal protected areas and OECMs can function as corridors.
OECMs allow Indigenous territories, private ranchlands, community forests, and regenerative working lands to count toward 30x30 if they deliver long-term biodiversity outcomes. Many of these lands already act as de facto corridors.
As temperatures shift, species must move upslope, poleward, along waterways, or into cooler microclimates. Corridors enable this movement, making them essential for climate adaptation.
Corridors give animals safe passage, reducing road collisions, crop damage, livestock predation, and dangerous encounters near communities. This increases public support for conservation and 30x30.
Rewilding restores natural processes that rebuild connectivity, including river and floodplain restoration, beaver-driven wetland creation, native grassland recovery, removal of obsolete fencing, and predator and herbivore dispersal routes. These restored systems naturally form continuous ecological networks.
Yes. Private lands can count toward 30x30 as OECMs if they support biodiversity, maintain ecological function, and have long-term conservation commitments. This makes corridor creation far more scalable.
Not always. Corridors can be continuous habitat, stepping-stone patches, riparian ribbons, or mixed-use landscapes with wildlife-friendly management. What matters is functional connectivity, not perfect continuity.
Corridors allow gene flow between populations, recolonization after disturbances, reduced inbreeding, and stronger population resilience. This is critical for species facing climate and habitat pressures.
30x30 pushes countries to map national wildlife movement routes, integrate connectivity into land-use planning, prioritize restoration in bottleneck areas, and coordinate across borders and jurisdictions. Corridors become a policy requirement rather than an optional conservation tool.
