Exo Terra Forest Bark Vivarium Substrate 4.4L (PT2750)

ET Forest Bark is a 100% natural fir bark substrate designed for humidity-loving reptiles, amphibians, and invertebrates. If you're keeping species that need consistent ambient moisture — tropical boids, chameleons, dart frogs, or bioactive setups — this is a substrate that actively works with your enclosure environment rather than against it.

Natural Composition

Made from 100% natural fir bark, this substrate contains no artificial additives or treatments. The organic structure of fir bark makes it a reliable choice for keepers who want a naturalistic vivarium floor that also performs a functional role.

Humidity Regulation

Forest Bark is hygroscopic — it absorbs moisture readily and releases it slowly back into the enclosure air. This helps buffer humidity levels over time, reducing the peaks and troughs that can stress sensitive species. Regular misting charges the substrate, which then maintains ambient humidity between sessions.

Behavioural Enrichment

The loose, chunky texture encourages natural digging and burrowing behaviour in species that exhibit it in the wild. Providing an outlet for these instincts contributes to a more stimulating and stress-reduced captive environment.

Practical Keeper Benefits

• Absorbs organic waste, helping to manage odour between cleans
• Decorative appearance suits naturalistic and bioactive vivarium setups
• 4.4L bag suitable for smaller enclosures or as a top-up supply

ET Forest Bark gives humidity-dependent species the substrate conditions they need while keeping maintenance straightforward — a dependable choice for any tropical vivarium build.
