From the surface, your pond’s ecosystem might look calm and quiet. Underneath the waterline, however, is a whole new world. From microscopic algae to large frogs, a healthy pond is home to various freshwater wildlife and pond creatures.
Whether you’ve built a backyard pond or are just curious about the natural world, learning about freshwater habitats can help you better care for your pond’s residents and attract new, beneficial critters. Even better, the wildlife and microorganisms in a pond provide a quick snapshot of the ecosystem’s health.
Let’s take a closer look at the animals, plants, and organisms that may call your pond home.
What Lives In A Pond?
A freshwater habitat consists of many related moving parts. Plants, animals, and microorganisms work together to achieve balance. Plants provide oxygen and shelter. Fish, frogs, and certain insects, like dragonflies, help control mosquitoes and other pest populations. And microscopic organisms break down organic matter, resulting in cleaner pond water.
Simple Pond Organisms
The term “pond organisms” refers to the tiniest pond inhabitants. The average pond has roughly 184 different microbes. Some more common ones include protozoa, bacteria, and even algae. They are often invisible to the naked eye (unless there’s an overgrowth of algae), but they’re essential for a balanced pond in the right quantities.
- Protozoa are single-celled organisms, such as amoebas. They are essential indicators of an ecosystem’s health and help keep bacteria populations in check.
- Bacteria break down fish waste, leaves, and debris. Too much, however, can harm your pond’s fish.
- Algae oxygenate the water and serve as food for many pond animals. Excessive amounts can cause green water or harmful blooms.
These simple pond organisms may be tiny, but they are vital to any pond ecosystem.
Common Freshwater Animals
A backyard pond can provide a home for many freshwater creatures. The wildlife a pond attracts depends on various factors, including geographic location, the size of the pond, and the health of the pond and its surrounding ecosystem. Some of the most common freshwater animals include frogs, toads, turtles, snails, and aquatic insects such as dragonflies and mosquitoes.
A preferential aquatic animal biome includes plants, shade, and other natural elements. Animals that live in lakes also require clean water and plenty of hiding spots.
Lake Animals and River Animals
You may encounter the occasional lake or river animal if you’re near a larger body of water or a river. These can be especially fun to catch as they are less common in a backyard pond.
Some lake and river animals you may spot include herons, muskrats, beavers, and small shore birds such as plovers and avocets. While these are not typical backyard dwellers, they are all a part of a thriving freshwater biome.
Building a Wildlife Pond
To attract wildlife, you must create a balanced freshwater ecosystem. Your pond should have some form of aeration, a good balance of plants and sunlight, natural features such as rocks or logs, and clean water.
You also may find yourself wanting to keep specific animal populations in check. Mosquitoes, raccoons, coyotes, and other unwanted visitors can create a problem for many backyard pond owners. Animal decoys, mosquito bits, and live traps can help you deter or remove unwelcome guests.
