Forest Health Conditions in Alaska. 2016
Editat de Forest Service (U.S.)en Limba Engleză Spirală – 20 apr 2017 – vârsta de la 18 ani
This report summarizes monitoring data collected annually by our Forest Health Protection team and some of our key partners. It is intended to provide technical assistance and information to stakeholders on the forest conditions of Alaska. The report also helps to fulfill a congressional mandate (The Cooperative Forestry Assistance Act of 1978, as amended) that requires survey, monitoring, and annual reporting of the health of the forests. This report also provides information used in the annual Forest Insect and Disease Conditions in the United States report.
Forestry technicians, conservation specialists, scientists, arborists, tree wardens, natural resource planners, and others involved in forest and wildlife protection would be interested in this report. Students pursuing coursework in natural resources management and forestry may also be interested in this primary source document.
