The paper marks the 15-th anniversary of the Wildfires Monitoring Information System of the Federal Forestry Agency (ISDM-Rosleskhoz). Creation and development of the system was partaken by many organizations, including the Aerial Forest Protection Central Base (Avialesookhrana), Space Research Institute of the Russian Academy of Sciences (IKI), Center for Forest Ecology and Productivity of the Russian Academy of Sciences (CEPF RAS), State Research Center "Planeta", OOO Inkom, Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences (ISTP SB RAS), Saint Petersburg Forestry Research Institute (SPbNIILH). The system provides uniform near real-time information necessary for forest fires and their impact monitoring all over the Russia territory and border areas. The paper highlights main trends and key stages of ISDM-Rosleskhoz development and evolution during the entire operation time span. This constant evolution has made and is keeping the system as the largest fires monitoring industrial system operated by Forest Protection Services both in Russia and in the world. The paper also briefly provides major development directions of the system for the nearest years.
