This is Scientific American 60-second science. I'm Julia Rosen. Got a minute?

In 1869, the Smiley family purchased a parcel of land about 100 miles north of New York City.

Over time, some of their property and much of the surrounding landscape became the Mohawk Preserve,

which has since grown to 8,000 acres and attracts droves of visitors to its thick forests and rugged crags, popular among rock climbers.

But the Mohawk Preserve also has a long scientific legacy.

In the 1930s, Dan Smiley, a descendant of the original owners, began keeping track of the plants and animals that lived in the area.

He wrote meticulous notes on the backs of menus

from the Mohawk Mountain House, a resort owned by his family. He would take these old menus

because he was green. He was environmentalists. So he would cut up these menus into squares

and actually on the back of all of our index cards or you can see parts of the menu from back

in the 1920s and 1930s. So you can see what was served for dinner that night. Meganopoli, a research ecologist with the Mohawk Preserve in New York.

Smiley's efforts produced a rare long-term data set of observations.

It's ideal for studying the impacts of climate change, which often play out over the course

of many decades and cause subtle changes in the timing of natural processes.

For instance, other research has shown that songbirds are migrating north earlier and earlier in the spring.

The reason that it's important that the birds arrive at the proper time in the spring is because

they need to time their arrival with the insect emergence.
