Using Live Plants in Reptile/Amphibian Enclosures/Vivariums
Using “live”, or living plants inside an enclosure or vivarium for your reptile or amphibian is rapidly growing in popularity, and there are both many different species and types of plants which may be used, as well as materials and methods by which it can be done. Live plants often make for great additions to many different enclosures and setups for a variety of reasons, including greatly improving the enclosure or vivarium’s aesthetics, or otherwise improving its beauty and naturalistic appearance. There are, however, several considerations to keep in mind prior to purchasing and planting live plants in a terrarium, including the selection of the right plants (each species will have its own heating/lighting, temperature, humidity, and water level requirements that should be compatible with the husbandry requirements for your animal). Other considerations to keep in mind can include where and how the plants that you use are purchased or acquired, the health and conditions of the prospective plants, what kind of biome setup one desires (desert, temperate, tropical, etc.) and the biology and natural history of the species of reptile or amphibian they are intended to be used for.
Regarding these considerations further, live or potted plants can be purchased or acquired from a number of hardware and/or garden centers and their wholesalers/suppliers, as well as sometimes from reptile/exotic pet specialty stores or shows. When purchasing a plant from any of these sources, always ensure they (as well as the potting soil/mixture they are planted in) are free of pesticides, synthetic fertilizer residues, or other chemicals that may potentially harm your animal. Plants should also be inspected and examined for their overall health and condition, and be free of a variety of plant or household pests such as aphids, mealy bugs, mites, snails and slugs, or other pest species. Lastly, it is important to consider the biology and habits of the species the plants are intended for. Live plants can work well for many reptile and amphibian species, including geckos, chameleons, other lizards, smaller snakes, and many amphibians such as dart frogs and mantellas, but many herbivorous to omnivorous species (such as tortoises, iguanas, bearded dragons, some skinks, and other lizards) may try to eat plants planted in the vivarium. Ensure that the plants selected for these animals are either planted or installed out of reach for the animal and/or are too tough and fibrous, or distasteful (but not toxic) to be preferentially eaten by the inhabitants, such as some larger bromeliads. Some other animals such as monitors, tegus, and other larger or heavier snakes, tortoises, and lizards will usually burrow and uproot or crush/trample live plants in the enclosure, and if they are to be used with these animals, should be very firmly planted or potted.
Benefits of Live Plants in a Bioactive Enclosure
By definition, a “bioactive” enclosure or setup is one in which natural, biological effects and processes can take place fully. In a vivarium, plants can very often serve as natural forms of waste management and buildup/accumulation of nitrogens caused by animal wastes, particularly from smaller or “micro” species in which wastes may be difficult to detect and/or remove. The nitrogen cycle is an important and relevant process that takes place, where wastes are broken down by bacteria into ammonia, and then nitrite and nitrates. A buildup of any of these over time can become toxic and unhealthy for your animal, and may even be fatal, unless conditions are regularly maintained or improved. Plants are often “end users” in the nitrogen cycle in that they will use and absorb all forms of nitrogen to live and grow in the enclosure. Furthermore, live planted plants help remove carbon dioxide from the air, and add and maintain valuable oxygen and humidity to the surrounding conditions via the carbon cycle.
Plants also provide many other direct and indirect benefits for all life, including acting as food sources for many, as well as shelter and refuge. Arboreal species of reptiles and amphibians (such as many species of frogs, geckos, other lizards and many snakes) spend considerable time climbing, basking and foraging among trees/plants and their stems, cavities, and trunks. Many terrestrial (ground dwelling), fossorial (burrowing), and aquatic species will also use plants and their root systems as cover as well. Many species are dependent on plants for all or parts of their reproduction. For instance, tadpoles and larvae of many Amazonian species of frogs and toads grow and develop in small standing pools provided by bromeliads and hollow tree cavities. Even fallen, downed, or dying plants and debris such as leaf litter, fallen bark, logs, hollow stumps, and fallen branches and brush piles can serves as habitat for numerous other plants and animals. This is why it is important to know the biology and natural history and lifestyles of the reptile or amphibian species you select, and select the appropriate complementing plants with relation to how all or portions of the plants may be utilized by the animal or species as a whole. Overall, when adding plants to a bioactive vivarium, it is important to replicate the species’ natural conditions as closely as possible. In fact, using the appropriate live plants for many species may very well further our knowledge and developments towards successfully being able to keep and reproduce additional species in captivity for future generations to see, enjoy, and learn more about.
Vivarium Plant Care and Maintenance
Many types of planted plants, once planted inside the terrarium or vivarium, will require little to no maintenance. Each species has their own lighting/heating, temperature, humidity, and watering requirements that won’t be discussed in detail here, but many other forms of information and resources are available. In general, good lighting (including access to natural sunlight when possible), as well as a good substrate mixture, and sometimes pruning, if required, are typically most, if not all that is required in maintaining these components to a bioactive enclosure.
