"Chase Lake National Wildlife Refugee"

Theodore Roosevelt established the Chase Lake National
Wildlife Refuge on this date in 1908. The refuge encompasses 4,385 acres
northwest of Medina and is one of states largest surviving blocks
of native prairie. As a wilderness area, no motor vehicles and no roads
are allowed, leaving the area almost identical to pre-settlement days.
The refuge is home to at least 230 bird species (some of them rare), 35
species of butterflies and untold numbers of wildflowers.
Chase Lake has also been home to the largest nesting
colony of American white pelicans on the continent approximately
half the North American population. This June, however, scientists were
baffled when approximately 29,000 pelicans disappeared from the refuge
in a matter of days. Experts have no concrete reason for why the birds
suddenly abandoned their eggs and hatchlings
no indication of disease
or undue disturbances of nesting habitat. Some theorize the cold, wet
spring altered the pelicans food supply, and others believe this
may be a natural population correction. They are optimistic
that the birds will return next spring.
