# how to help save the florida panther

*the caloosahatchee crossing: fund corridors, crossings, and survivable roads*

the florida panther is not “a species problem.” it’s a map problem.

there are panthers. there is habitat. and then there is everything in between: highways, canals, subdivisions, fences—friction.

**coryi** is the florida panther (puma concolor coryi), the last wild cougar population in the eastern united states. after dropping to fewer than a few dozen animals in the 1970s, the population rebounded through aggressive protection and genetic rescue. today, public estimates commonly land around **~120–230 adult/subadult panthers** in the breeding range—still a fragile number for an animal that needs space.

## why one cat needs so much land

a single adult male can range across something like **~200 square miles** of connected habitat. that doesn’t mean “200 square miles of forest somewhere.” it means **200 square miles that behave like one place**—where a panther can move, hunt, find mates, and raise kittens without getting pinned into an island.

when habitat breaks into islands, small populations become vulnerable to:

- **road mortality** (still a leading cause of death)
- **inbreeding** (a symptom of isolation)
- **conflict** (cats pushed into human edges)

the next chapter isn’t just “more protection.” it’s **connection**.

## the caloosahatchee barrier

the caloosahatchee river has functioned like a hard line on the panther’s map—an ecological border created by development and roads as much as by water. expanding the breeding range north of this barrier is one of the clearest long-term requirements for a self-sustaining panther population.

in practical terms, that means:

- **protecting corridors** (the land that allows movement)
- **building crossings** (underpasses/overpasses that reduce vehicle strikes)
- **reducing edge friction** (fencing, lighting, speed, planning)

this is conservation as civil engineering.

## ensuring corridors (not just counting cats)

ensurance is built for this kind of problem: funding *the conditions* that keep a species alive, not just reacting after loss.

the coryi coin routes initial funding into the three protection channels that matter most for panther persistence:

- **temperate-forests.ensurance**
  - `0xe0f3242d908f10E95B634Ec13751350424f10501`
- **inland-wetlands.ensurance**
  - `0x7D19d271E587418974B2966dE43F87C9f7fD505f`
- **habitat.ensurance**
  - `0xa04c3EB7b8004Fa3B5BeAF54044A0F1F2E2B24C7`

trading generates **ensurance proceeds**—ongoing flows that can support corridor acquisition, easements, monitoring, and the unglamorous work of making roads survivable.
