Skunk cabbage, a plant that contains crystals of the deadly substance oxalic acid, specifically crystals of calcium oxalate, is a common food source for deer in the spring.

When skunk cabbage initially appears in the spring, deer seek it and consume the green leaves and the yellow flower spike. In addition to having harmful substances, it is also high in protein, which is essential for hungry deer following the sparse winter harvest.

The majority of forbs and browse found in nature are laden with poisonous substances.

Deer probably adapt to this by eating a range of plants, consuming toxic plants in moderation, and focusing on more nutritious plants when they are available.

Deer will consume multiple plant species at once, and this combination of plants in the digestive tract may lessen or eliminate some meals’ hazardous effects.

Final Thoughts

Symbiotic bacteria found in the first two of an animal’s four numerous stomachs, or rumen-reticulum, aid animals like deer, moose, and cows digest the plant they consume.

The microorganisms in moose’s digestive tract alter when they transition from consuming green vegetation in the summer to twigs and woody browse in the winter, and the microbes more suited to the winter diet become much more prominent.

Similar to this, consuming modest amounts of plant poisons can cause microbial adaptations in the stomach, giving the animal’s body a chance to adjust to the toxin. This explains why various members of the same species may have varied dietary tolerance levels.
