Impacts of White-Nose Syndrome

White-nose syndrome has caused a great deal of impact across North America, not only to the bats themselves but also their environments. The primary and most substantial impact being that it has decimated an estimated 6.7 million North American bats, cases have documented the mortality rate of bat populations inflicted with WNS to be as high as 95%! It does not stop there however. Bats are very productive members of their environment. They play a very large role in maintaining economical balance amongst their community. Bats serve as the primary predators for nocturnal-flying insects, meaning they are the primary consumer of insects like mosquitos, moths, beetles, and various other pests. Bats eat thousands of insects nightly, consuming roughly half their weight in insects each time. By keeping these insect populations in check bats play a large role in forestry, agriculture, as well as human health. The decrease in bat population has led to a vast increase in nocturnal-flying insect population leaving their ecosystems in a state on unbalance. With no consumer to regulate the amount of nocturnal-flying insects their numbers flourish which takes a grave toll on the agricultural industry. These insects are left to freely gorge themselves on agricultural crops leaving less food for other members of the ecosystem as well as cutting a large amount of profit for agricultural workers. According to www.batconservation.org bats save the agricultural industry “at least” $23 billion dollar annually because the farmers do not have to purchase as many pesticides. The decrease in bat population causing the agricultural industry to purchase more pesticides may result in the increase of food costs in order to make up for expenses and lost profit. In tropical environments bats also serve as aids in pollinating plants and dispersing seeds. Bats eat fruit and pick up pollen from plants which they transfer to other plants resulting in pollination. Similarly by eating fruit, seeds become dispersed throughout the environment whether they be deposited to new location through feces or unknowingly attached to the bats fur then randomly discarded. That being said the decline of bats has taken a grave toll on various environments, causing a plethora of issues and inconveniences. Not to mention, they are also really cute, and nobody likes when cute things die…
