Conservation Efforts

Many conifer trees are threatened by deforestation, climate change, and other human activities. Conservation efforts are underway to protect these important species and their habitats.

One such effort is the Redwood National and State Parks in California, which protects over 139,000 acres of redwood forest. Another example is the Great Bear Rainforest in British Columbia, Canada, which is home to many conifer species and is one of the largest intact temperate rainforests in the world.

In this guide, we have explored the diverse world of conifer trees, from the towering redwoods to the diminutive cedars. Each species has its unique characteristics, uses, and conservation challenges. However, they all share a common beauty and importance in our natural world.
