In school we learned that what makes a rain forest a huge and dense forest is, well, the rain. Alaska actually advertises its soggy and mossy pine forests as northern rain forests. I've wondered why Norway doesn't do the same. In the summer, this wet country is as lush as a tropical rain forest. Anywhere from 18 to 24 hours of daylight in the middle of summer and a lot of rain makes everything grow incredibly fast. We don't have the tall, dense canopies of the tropics; our denseness tends to be closer to the ground. But the huge number of trees, the millions of leaves, create a solid green along roads, up mountainsides, across vistas, and around my local pond.
Summer where I live has been cool and wet. Nature seems not to care. The moment the ground thaws and temperatures stay somewhere above 10 C, stuff grows. Norwegians with lawns find themselves a bit frustrated: All the rain makes the lawns grow fast, but all the rain makes it impossible to mow said lawn. What we learned early in school about plants thriving on sunlight and water is never clearer than when looking at the lushness of my local pond.
The combination of blue and green, of water and leaves, is always attractive and calming to humans. Never more so during an undisturbed moment, viewed through thick foliage on a late summer's day.
