This is mostly due to the inaccessibility of larger forest complexes on account of the underdeveloped forestry road network, as well as the general absence of modern optoelectronic equipment for early detection, reporting and warning of forest fires, and limited technical capacities resulting from the lack of modern fire-suppressing equipment, vehicles and special aircraft. Estimates from 2004 show that, on average, over 7,400 tons valued at US$ 10 million are exported each year. Control over unauthorized collection of such plants has improved in recent years, and the pressure has slightly decreased, which is also due to the educational campaigns, training and technical assistance provided under the Private Forestry Development Programme.
