More than 100,000 trees — including many beautiful live oaks and magnolias — were lost when Hurricane Katrina devastated New Orleans in 2005.

In response, Hike For KaTREEna — a nonprofit group dedicated to reforesting the Crescent City — was created.

Since 2006, more than 10,000 volunteers have helped to plant 13,400 trees — including oaks, cypress, red maples, crepe myrtles, magnolias, redbuds, Savannah hollies and citrus trees such as navel orange, satsuma, lemon, lime and grapefruit.
