Exo Terra Forest Bark Substrate

Exo Terra Forest Bark is a natural fir bark substrate designed for tropical and forest-dwelling reptiles, amphibians, and invertebrates that require consistent humidity in their enclosure. Available in a range of sizes to suit vivariums of different scales, it works actively to maintain the damp conditions that humidity-dependent species need to thrive.

Humidity Regulation

Fir bark is hygroscopic by nature — it draws in moisture and releases it gradually back into the enclosure air. This makes Forest Bark an effective tool for stabilising humidity levels over time, reducing the need for constant misting and helping to replicate the damp forest floor environments many tropical species come from.

Encouraging Natural Behaviour

The loose, chunky texture of bark substrate supports natural digging and burrowing instincts. For species that would naturally root through leaf litter and decomposing bark in the wild, this provides meaningful environmental enrichment within the terrarium.

Practical Husbandry

• 100% natural fir bark — no artificial additives
• Absorbs waste to help keep the enclosure cleaner between full substrate changes
• Hygroscopic properties actively support ambient humidity control
• Visually naturalistic — suits bioactive and display-focused setups

Choosing the Right Size

Forest Bark is available in several bag sizes, from smaller quantities suited to compact terrariums through to larger volumes for bigger enclosures or keepers who prefer to buy in bulk. Select your preferred size from the options above to suit your setup and how frequently you change substrate.

A reliable, purpose-built substrate for any keeper housing tropical reptiles, amphibians, or invertebrates — Forest Bark takes the guesswork out of humidity management and keeps the enclosure looking as natural as it functions.
