Which class of trees can survive harsher climates?

Coniferous trees, such as pines, spruces, and firs, are well-adapted to survive harsher climates, particularly in colder regions. Their needle-like leaves reduce water loss and allow them to withstand freezing temperatures and snow accumulation. Additionally, conifers typically have deep root systems that help them access water in challenging environments. This adaptability makes them resilient in areas with extreme weather conditions.
