Reindeer Of St. Matthew Island Worksheet Answer Key Guide
Table of Contents :
The Reindeer of St. Matthew Island is a fascinating case study in ecology and population dynamics that has garnered attention from scientists, educators, and students alike. This article serves as a comprehensive guide to help you understand the key concepts surrounding the reindeer population on St. Matthew Island, along with an answer key that will aid in your studies.
Overview of St. Matthew Island
Located in the Bering Sea, St. Matthew Island is a remote and rugged landmass known for its unique wildlife and ecological dynamics. In the 1940s, reindeer were introduced to the island for research and potential hunting purposes. However, this introduction led to unforeseen consequences, demonstrating the delicate balance of ecosystems and the impact of human intervention.
The Introduction of Reindeer
In 1944, a herd of 29 reindeer was introduced to St. Matthew Island. The initial motivation was to create a sustainable population for future hunting, but the results were far beyond what was anticipated. The reindeer thrived due to the island's abundant vegetation and lack of predators, leading to an exponential increase in their numbers.
Key Points:
- Initial Population: 29 reindeer
- Introduced Year: 1944
- Lack of Predators: Allowed for rapid population growth
Population Explosion
The reindeer population increased dramatically, reaching over 6,000 individuals by the 1960s. This rapid growth led to overgrazing and a subsequent decline in the island's vegetation. As food sources dwindled, the reindeer faced starvation, leading to a population crash in the late 1960s.
Population Growth Table:

Decline of the Reindeer Population
By the early 1970s, the reindeer population had plummeted to zero. This decline illustrates the consequences of introducing a non-native species into an ecosystem without considering the potential ecological ramifications. The reindeer overgrazed the vegetation, leading to severe habitat destruction and a subsequent failure to recover.
Important Note:
"The case of the reindeer on St. Matthew Island serves as a cautionary tale about the management of wildlife and the importance of understanding ecological balance." 🌿
Ecological Implications
The reindeer story is not merely a tale of population dynamics; it offers critical insights into ecological principles such as carrying capacity, overpopulation, and the role of predators. The loss of the reindeer also affected the island's ecosystem, demonstrating how interconnected all elements of an ecosystem are.
Carrying Capacity
Carrying capacity refers to the maximum population size that an environment can sustain indefinitely. The reindeer exceeded the carrying capacity of St. Matthew Island, leading to habitat degradation and eventual extinction. Understanding carrying capacity is essential for effective wildlife management and conservation efforts.
Overpopulation Effects
The overpopulation of reindeer on St. Matthew Island serves as an important lesson on the impacts of overpopulation, not just on the species itself but also on the entire ecosystem. Overgrazing leads to soil erosion, loss of plant species, and a collapse of the food web.
Lessons Learned
The reindeer of St. Matthew Island highlight several crucial lessons for wildlife management, ecology, and conservation:
- Invasive Species Management: The dangers of introducing non-native species must be considered before any action is taken.
- Ecological Balance: Maintaining the balance within ecosystems is crucial to prevent population crashes.
- Sustainable Practices: Understanding and respecting the natural limits of an environment can help ensure the longevity of species.
Conclusion
The story of the reindeer on St. Matthew Island is both a warning and an educational opportunity. By studying this case, we can better appreciate the delicate nature of ecosystems and the profound effects of human intervention. Whether for schoolwork or personal interest, understanding the dynamics of the St. Matthew Island reindeer population offers valuable insights into wildlife management and ecological studies.
