Komodo Dragon: How Many Are Left in the Wild?

Species deep dive · komodo dragon

Roughly 4,000 Komodo dragons live in the wild, and all of them are in Indonesia. The Komodo National Park office counted about 3,270 dragons (± 371) across the park's five islands in 2024, and a separate survey puts about 700 (± 131) on the coast of Flores (Indonesian Ministry of Forestry). Only a fraction of those are breeding adults: the IUCN Red List counts 1,383 mature individuals and lists the species as Endangered (IUCN Red List).

So the honest answer is "a few thousand lizards, but only about fourteen hundred grown-ups", and the two numbers mean different things. Here is where they come from, and why a population that looks stable is still on the Endangered list.

The yearly count in Komodo National Park

The park office and the Komodo Survival Program survey 11 monitoring sites across the five dragon islands every year, using camera traps and site-occupancy models rather than a head count of every animal (Indonesian Ministry of Forestry). These are the park-wide estimates (ANTARA News):

The park describes the trend as relatively stable and slightly rising over seven years, with numbers going up and down with the deer, pigs and buffalo the dragons eat (ANTARA News).

Almost all of those dragons live on two islands. The 2023 count split like this: Komodo 1,694, Rinca 1,509, Nusa Kode 92, Gili Motang 70 and Padar 31 (VOI / ANTARA). Padar is a story of its own. Its dragons disappeared after poachers emptied the island of deer, and for decades they were thought gone: the Smithsonian's National Zoo reported that none were seen there from the 1970s onward (Smithsonian's National Zoo; Indonesian Ministry of Forestry). The 2023 park tally recorded them on Padar again, with 31 counted.

Flores: the dragons outside the park

Flores is by far the biggest island in the dragon's range, but there the lizards live mostly outside protected areas, among farms and villages. Over five years, researchers ran 346 camera stations along the Flores coast and detected dragons at just 85 of them, in three isolated pockets on the west, north-west and north coasts. Being close to farms and villages had the strongest negative effect on whether dragons used an area (Ariefiandy et al. 2021).

The government's action plan adds that feral dogs compete with dragons for prey: wherever cameras picked up lots of dogs, they picked up few or no dragons (Indonesian Ministry of Forestry).

Why "stable" still means Endangered

The IUCN assessment (assessed 2019, published 2021) lists the Komodo dragon as Endangered under criterion C1, which is about a small number of mature adults combined with an expected decline. It records 1,383 mature individuals in 8 locations, a generation length of 15 years, and a population trend of "stable" (IUCN Red List).

Three things make a few thousand island lizards fragile:

• They hardly move. Tracking, translocation and genetic studies show that Komodo dragons rarely leave the valley where they hatched, even though they are big and capable walkers (Jessop et al. 2018). A local loss isn't quickly refilled from next door.
• The islands are small and low. A climate model built on years of monitoring data projected that dragon habitat could shrink by 8–87% by 2050, with abundance falling by 27–99% depending on the emissions scenario. Komodo and Rinca came out as the safest refuges (Jones et al. 2020).
• Their food can be taken away. Padar shows what happens when the deer go.

What about zoos?

Zoos keep a backup population but nowhere near a second wild one. The Species360 ZIMS database listed 258 Komodo dragons in 102 facilities across 28 countries in 2024 (Indonesian Ministry of Forestry). Indonesia's plan treats them as a genetic reserve and wants future releases to wait until the genetics of wild and captive dragons are properly mapped, because the Komodo Island and north Flores populations are genetically distinct.

How the Komodo dragon plays in Wilder

The Komodo Dragon (Varanus komodoensis) is a Rare Reptilia card in the Grassland element. It costs 6 Energy, with Attack 6 and Health 8, and it has Basking, Feast and Thorns. Its active ability gives it Venom for 3 Energy, a nod to the real venom glands in its lower jaw. Flavour text: "One bite. Then patience."

Wilder is a free browser collectible card game about real animals, and you can play it free in your browser with no signup.
