The Environmental Impact of Sevin
- Bertwell, R.L.
Forest insects which are recognized as one of the greatest single hazards to forest crops have been periodically estimated by various independent and governmental agencies to be responsible for 30-40% of all the losses of saw timber and 20-30% of those of growing stock. Such losses indicate that at times forests must be protected from insects if we are to have:
1. Lumber, pulp, and other wood products,
2. Clean water for irrigation, hydroelectric power, as well as industrial, and domestic water needs,
3. Meadows and grasslands for grazing of domestic livestock and wildlife,
4. Suitable habitats for fish and wildlife sought by millions of fishermen and hunters,
5. Scenic areas for camping, vacationing, and recreation.
