Early in the first winter studied, prevalence of P. destructans was very low, and although transmission resulted in most bats harboring P. destructans by winters' end, declines in bat populations were limited.
As a result, natural and cultural resource managers seek to ensure public safety and protect historical structures while minimizing impacts on bats, especially in light of declines in bat populations as a result of WNS.
It was first discovered in North America in 2006 and spread rapidly, causing massive declines in bat populations across the northeast.
A recent study found that the decline in bat populations may cost farmers -- who rely on the mammals to eat insects -- more than $3.7 billion per year.
Although many of these bats can fly long distances, loss of roosting areas at the landscape level should ultimately cause declines in bat populations regardless of the availability of food or preferred habitats.
The destruction or degradation of their foraging habitats, usually a consequence of land use intensification, is one of the main factors that is contributing to the decline of bat populations [1].
Also, hunters, vendors and consumers who rely on E. helvum for secondary protein and income sources (Kamins et al. 2011) might start to experience a decline in quality of life if bat populations declined severely.
As of September, 2017, the disease had spread to thirty-one states, some of which have suffered ninety-per-cent declines in their bat populations; the crisis, which began in New York, now extends as far west as Washington.
Bats with symptoms of white-nose syndrome (WNS) were first detected in the United States in 2006, and the disease has subsequently caused precipitous declines in temperate bat populations across eastern North America (3, 4 ).
