Have you ever seen a forest destroyed by fire? A great forest fire is an awful thing to see. Once a fire has started, it spreads quickly. Foresters say that late summer is the season when fire is the greatest danger to woods and forests. They are very dry then. Sometimes when the danger of fire is very great, foresters will not allow anyone to go into the forests. If people leave a campfire burning near a heap of leaves, this often causes a forest fire. Campers must always remember to put out their campfires and cover the place with earth. It is the duty of every camper to take the greatest care not to start a forest fire. Anyone careless enough to start a forest fire has done something, which makes life more difficult for all of us. Every fire destroys valuable wood, wildlife, and good soil. Everyone of us must know how important it is to care for our great forests and save them from fire.

Cuc Phuong, the first national park in Vietnam, was officially opened in 1960. it is located 160 km south west of Hanoi spanning Ninh Binh, Hoa Binh and Thanh Hoa provinces. The 200 square kilometre park attracts tourists and scientists alike. In 2002, nearly 100,000 visitors made their way to Cuc Phuong. Many come to see the work being done to protect endangered species. According to scientists, there are about 2,000 different species of flora and 450 species of fauna.
Cuc Phuong National Park has many caves. Quen Voi, also part of the park, is where Nguyen Hue’s army was stationed before it made its surprise attack on Thang Long and defeated the Quing invaders in the spring of 1789. Cuc Phuong is also home to the Muong ethnic minority, who live mainly on bee keeping and farming.
