Exo Terra Forest Bark

Exo Terra Forest Bark is a natural Fir bark substrate designed for humidity-loving reptiles, amphibians, and invertebrates. Available in a range of sizes to suit terrariums of different scale, it supports a bioactive-style environment while keeping maintenance straightforward for the keeper.

Natural Humidity Regulation

Forest Bark is hygroscopic, meaning it readily absorbs and releases moisture into the enclosure. This makes it well-suited to species that require elevated ambient humidity, helping to stabilise conditions without constant manual intervention. Misting the substrate allows it to act as a natural humidity reservoir throughout the terrarium.

Encourages Natural Behaviour

The loose, chunky texture of Fir bark gives reptiles and amphibians the opportunity to dig and burrow — behaviours that are important for physical and psychological wellbeing in captivity. A substrate that supports natural activity is always preferable to one that simply sits inert beneath the animal.

Practical and Decorative

• 100% natural Fir bark — no artificial additives
• Absorbs waste to help manage enclosure hygiene
• Visually appropriate for forest, rainforest, and woodland setups
• Complements live or artificial planting in bioactive and naturalistic builds

Choosing the Right Size

Forest Bark is available in multiple bag sizes to suit everything from a compact arboreal setup to a large, heavily planted terrarium. Select the option that matches your enclosure volume and how frequently you refresh your substrate — a larger bag is worth considering if you're setting up a new build or maintaining a sizeable enclosure.
