In the twentieth century, Soviet zoologist Nikolai Velechagin embarked on an ambitious mission to revive the scene of ancient Caucasian fauna that had long been extinct, leaving a mark that is still visible in Azerbaijan today. Through a series of archaeological discoveries and exciting experiments, Velechagin sought to reshape the ecosystems of the region, leading to the introduction of new non-native species. These initiatives were not merely scientific research but experiments that would leave negative impacts on the biodiversity of the Caucasus. In this article, we explore that strange experience of one man and how it affected the environment in Azerbaijan, as well as what we can learn from his story regarding the introduction of alien species and dealing with them in our current time.
The History of Nikolai’s Project in the Caucasus Ecosystems
Russian zoologist Nikolai Velechagin played a major role in documenting the history of ecosystems in the Caucasus during the mid-twentieth century, embarking on an ambitious mission to gather information about the extinct animals from this region. Velechagin used his discoveries to present a comprehensive narrative spanning 11,000 years, tracing the environmental changes that occurred as a result of climate change and indiscriminate human activity. In his book “Mammals of the Caucasus,” he created an intersection between ancient archaeological data and modern hunting stories, contributing to a new understanding of the environment of the Caucasus region and human impacts on that environment.
Impact of Introducing Non-Native Species
Velechagin’s goal went beyond merely documenting history; he also sought to reshape ecosystems by introducing non-native animals to the region. In Azerbaijan, several mammal species were introduced, but the most impactful was the muskrat, which was introduced for its fur in the clothing industry. Velechagin and his team did not realize the environmental consequences of this process, and as a result, the attempt to refill these ecosystems led to catastrophic changes. The muskrat, currently considered one of the worst invasive species in the world, spread to almost all wetland areas in Azerbaijan, impacting local biodiversity.
Dimensions of Scientific and Environmental Research on the Muskrat
The muskrat has been a major point of interest for researchers over the years, especially in light of some research efforts aimed at measuring its impact on the environment. Zulfu Farjaliev, an environmental researcher, led campaigns to raise awareness about the problems caused by the introduction of non-native species. Farjaliev aims to encourage the scientific community to study the spread of the muskrat and assess the damage it may cause to those ecosystems. Many experts question the population of muskrats in Azerbaijan and the true impact they have had on wetland environments.
The History of the Muskrat as an Invasive Species and Its Transcontinental Impact
The history of the muskrat extends beyond Azerbaijan, as it has spread across many continents, reaching unintended places as a result of fur farming. The muskrat began to emerge as a bred species in fur farms during modern times, quickly revealing this animal’s ability to adapt to new environments. Human experiments with the muskrat varied, including its use as food in some countries during certain periods, but its uncontrolled spread has been a major cause of the threats facing biodiversity in various regions.
Observing the Effects of Public Policies on Biodiversity
During the Soviet period, policies were enhanced to encourage muskrat populations to descend into natural environments, as these species were considered undesirable. For example, there was a substantial financial reward for anyone who killed wolves, contributing to an unchecked increase in muskrat numbers. These operations are part of a long history of environmental experiments, where ecological balances were dismissed in the name of improving agricultural productivity or meeting market needs.
Lessons
Lessons Learned from the Caucasian Experience
The experience of introducing the coypu to the Caucasus reflects important lessons about the impacts of non-native species on new environments. There is an increasing urgency to conduct in-depth research on environmental practices and how to manage species sustainably. Additionally, Vereshchagin’s experiences serve as a warning for understanding ecological balance and highlight the potential consequences of any human intervention in natural ecosystems.
History of the Coypu’s Arrival in Azerbaijan
The coypu is a native species of South America, but its arrival in Azerbaijan was the result of human intervention in natural habitats. This species was introduced to the region in the 1920s, which marked the beginning of an environmental crisis in the local ecosystem. Although the goal of introducing it was hoped to increase biodiversity in the area, the outcomes were the opposite. These animals managed to thrive and spread rapidly, disturbing the ecological balance in Azerbaijan. According to research, the initial number of coypus introduced was 213, and since then, their numbers have multiplied into the thousands at present time.
This growth statistic indicates the coypu’s ability to adapt and thrive in new environments, which has raised concerns among environmental experts. In a short period, these animals were able to establish a strong presence in various regions, including Armenia and Georgia. The impact of the coypu extends to the wetland areas and fragile ecosystems in Azerbaijan, making it essential to understand how to manage and control their spread.
The Effect of the Coypu on Biodiversity
The coypu is an invasive species that significantly affects biodiversity. Areas experiencing the spread of the coypu, such as the Gizilagh Nature Reserve on the Caspian Sea coast, face major threats. This reserve is an important point for millions of migratory birds, including endangered species. The coypu is known to negatively impact nests, leading to declines in bird populations in these areas.
Experiments conducted in other regions, especially in Italy, have shown that the coypu destroys natural habitats by heavily sitting on nests and breaking eggs. Similarly, visitors during birdwatching trips in Azerbaijan observe the presence of coypus in the same habitats occupied by waterfowl. These dynamics indicate the need for further research to understand the relationship between the coypu and local wildlife, as well as how to manage this species effectively.
Coypu Management Strategies
Completely eradicating the coypu is challenging due to the complexity of environmental conditions and the logistical challenges associated with organizing campaigns. For example, the United Kingdom successfully reduced coypu numbers through systematic culling campaigns during the 1970s and 1980s, but this strategy may not be feasible or effective in other areas where numbers are too high and resources are lacking.
Instead of eradication, several countries, including some U.S. states, rely on control strategies to limit their harmful effects. For example, Louisiana offers financial rewards for turning in coypu tails, which helps mitigate damage to ecosystems. In Azerbaijan, a proposal exists to restore a reward system to counter invasive species, where hunters are exempt from fees related to hunting coypus.
However, this approach comes with risks, as increased rewards often encourage indiscriminate hunting rather than actual control efforts. Therefore, it is important for strategies to adopt a long-term approach not only to remove coypus but to control their populations after a decline. In the short term, wildlife managers may need to raise awareness among local communities about the impact of coypus and the importance of preserving local ecosystems.
Awareness
Changing Local Behavior
One of the main obstacles in addressing the spread of the coypu in Azerbaijan is the lack of public awareness about the risks of its presence. Most locals are unaware of the negative environmental impact these animals have on the ecosystem, so it is essential to change this behavior. Awareness campaigns are needed to convey information about how the coypu affects local wildlife, including threatened migratory birds.
Local communities such as herders and fishermen need to realize that by allowing the coypu to spread, they are undermining the biodiversity upon which they depend. Education is key here, as local educational programs can teach people about the negative effects of bringing in invasive species and how participation in natural resource management can be beneficial.
Moreover, the government must take effective steps to promote laws and regulations aimed at protecting local species and biodiversity. Continuous communication with the local community is an essential part of the success of any management strategy. Furthermore, we must remember that we are part of the ecosystem and that any human intervention must be carefully considered to prevent harm and preserve the ecosystems upon which living beings rely.
