Highbush cranberry, also known as Viburnum opulus var. americanum, is a deciduous shrub native to North America. It is widely cultivated for its attractive flowers, berries, and ability to attract wildlife. However, like any other plant, highbush cranberry is not immune to predators. In this article, we will delve into the world of animals that feed on highbush cranberry, exploring the various species that eat its leaves, stems, and berries.
Wildlife that Eats Highbush Cranberry
Highbush cranberry is a valuable food source for various wildlife species. The plant’s berries, in particular, are a staple food for many birds and small mammals. Here are some of the most common wildlife species that eat highbush cranberry:
Birds
Birds are among the primary consumers of highbush cranberry berries. Many bird species, including:
- Robins
- Blue jays
- Woodpeckers
- Finches
feed on the berries, using them as a source of energy and nutrients. The berries are rich in antioxidants, vitamins, and minerals, making them an essential part of a bird’s diet.
Small Mammals
Small mammals, such as:
- Rabbits
- Squirrels
- Chipmunks
- Mice
also feed on highbush cranberry berries. These mammals often cache the berries, storing them in hidden locations to retrieve later. This behavior helps to disperse the seeds, promoting the spread of highbush cranberry.
Deer and Other Large Mammals
Deer, particularly white-tailed deer, feed on highbush cranberry leaves and twigs. Other large mammals, such as elk and moose, may also browse on the plant’s foliage. While deer can be beneficial to the ecosystem, overgrazing can harm highbush cranberry plants, reducing their growth and productivity.
Insect Pests that Feed on Highbush Cranberry
In addition to wildlife, various insect pests feed on highbush cranberry. These pests can cause significant damage to the plant, reducing its growth and productivity. Some common insect pests that feed on highbush cranberry include:
Aphids
Aphids are small, soft-bodied insects that feed on highbush cranberry sap. They can transmit plant viruses and reduce the plant’s growth rate. Aphids are often found on the underside of leaves and on stems.
Scale Insects
Scale insects are armored insects that feed on highbush cranberry sap. They can cause significant damage to the plant, reducing its growth and productivity. Scale insects are often found on the stems and branches of highbush cranberry.
Spider Mites
Spider mites are tiny, spider-like insects that feed on highbush cranberry sap. They can cause yellowing or bronzing of the leaves and reduce the plant’s growth rate. Spider mites are often found on the underside of leaves.
Managing Pests that Feed on Highbush Cranberry
Managing pests that feed on highbush cranberry requires a multi-faceted approach. Here are some strategies to help manage pests:
Cultural Controls
Cultural controls involve modifying the growing conditions to prevent pest infestations. Some cultural controls include:
| Control | Description |
|---|---|
| Pruning | Prune highbush cranberry plants regularly to promote air circulation and reduce humidity. |
| Watering | Water highbush cranberry plants deeply but infrequently to prevent overwatering. |
| Fertilization | Fertilize highbush cranberry plants regularly to promote healthy growth. |
Biological Controls
Biological controls involve using natural predators or parasites to control pest populations. Some biological controls include:
- Encouraging beneficial insects, such as lady beetles and lacewings, which prey on aphids and other pests.
- Introducing parasitic wasps, which prey on scale insects and other pests.
Chemical Controls
Chemical controls involve using pesticides to control pest populations. However, chemical controls should be used as a last resort, as they can harm beneficial insects and the environment. Some chemical controls include:
- Insecticidal soap, which can be used to control aphids and other soft-bodied insects.
- Horticultural oil, which can be used to control scale insects and other armored insects.
Conclusion
Highbush cranberry is a valuable food source for various wildlife species, including birds, small mammals, and deer. However, the plant is also susceptible to insect pests, such as aphids, scale insects, and spider mites. Managing pests that feed on highbush cranberry requires a multi-faceted approach, including cultural, biological, and chemical controls. By understanding the predators that feed on highbush cranberry, we can better manage the plant and promote its growth and productivity.
What is Highbush Cranberry and why is it important to know its predators?
Highbush Cranberry is a type of shrub that is native to North America. It is a popular ornamental plant due to its attractive flowers, berries, and fall foliage.

These animals feed on the plant’s leaves, stems, and berries, causing damage and affecting its growth. Insects such as aphids and spider mites also feed on the plant’s sap, causing damage to its leaves and stems.
Other predators of Highbush Cranberry include small mammals such as mice and voles, which feed on the plant’s seeds and berries. These animals can cause significant damage to the plant, especially during the winter months when other food sources are scarce. By knowing the common predators of Highbush Cranberry, gardeners and wildlife enthusiasts can take steps to protect the plant and maintain its health.
How do deer affect Highbush Cranberry plants?
Deer are one of the most significant predators of Highbush Cranberry, as they feed on the plant’s leaves, stems, and berries. Deer can cause significant damage to the plant, especially during the winter months when other food sources are scarce. They can also spread disease and pests to the plant, affecting its growth and health.
To protect Highbush Cranberry plants from deer, gardeners can use repellents such as predator urine or hot pepper spray. Fencing can also be effective in keeping deer away from the plant. Planting deer-resistant plants around the Highbush Cranberry can also help deter deer from feeding on it.
What role do birds play in the ecosystem of Highbush Cranberry?
Birds play a crucial role in the ecosystem of Highbush Cranberry, as they feed on the plant’s berries and help disperse its seeds. Birds such as cedar waxwings and American robins are attracted to the plant’s berries, which provide them with a source of food during the winter months. By feeding on the berries, birds help disperse the plant’s seeds, allowing it to spread and grow in new areas.
However, birds can also cause damage to Highbush Cranberry plants, especially if they feed on the plant’s leaves and stems. To protect the plant from bird damage, gardeners can use netting or bird-repellent balloons. Planting bird-friendly plants around the Highbush Cranberry can also help attract birds to the area and reduce damage to the plant.
How can I protect my Highbush Cranberry plants from predators?
To protect Highbush Cranberry plants from predators, gardeners can use a combination of methods, including repellents, fencing, and plant covers. Repellents such as predator urine or hot pepper spray can be effective in deterring deer and other animals from feeding on the plant. Fencing can also be used to keep deer and other animals away from the plant.
