The data on the sanitary and forest health of monitoring of the forested area in the Kaliningrad region are presented. The influence of the main factors on the sanitary and forest health of plantations for the period from 2017 to 2019 is considered, considering forest fires, unfavorable weather and soil-climatic conditions, the foci of pests and diseases, as well as anthropogenic and non-pathogenic factors. Their threat to forest plantations is analyzed. The main reasons for the forest plantations death in the Kaliningrad region are highlighted, they are negative weather and soil-climatic conditions (65 % of the total damaged area) as well as diseases. The study results of the forested areas with the established weakening and dying, the distribution of foci of pests and diseases are presented. The main insect pest, i.e. typographer bark beetle (Ips typographus), has been determined. The absence of insects as forest pests, listed in the Red Data Books of the Russian Federation and the Kaliningrad Region, and classified as quarantine pests, was recorded. The impact of negative factors causing the weakening (drying out) of forest plantations in the Kaliningrad region has been analyzed, it is recommended to conduct forest health monitoring, sanitary and recreational activities, perform reclamation work, strengthen control over the timing and quality of forest protection measures, and sanitary cuttings in particular, by the authority executive power of the subject and its subordinate institutions.

Forest fire is one of the problem in forest management. The objectives of the study was to measure the forest fire severity based on soil physical and chemical properties. The forest fire effects were assessed using fire severity method and forest health monitoring plot. The study indicated that the burned areas at BKPH Parung Panjang after two years included in low fire severity. The site properties and growth performance analysis showed that the fire has only affected on pH, Mg and tree diameter significantly, whereas the other parameters such as bulk density, P, N, Na, K, Ca and height were not significantly affected. In addition, both burned and unburned areas are classified as in health condition.Key words : fire severity, forest health monitoring, growth performance, site properties

Pine (Pinus merkusii) is tree species that provides timber and gum rosin. To meet the needs of wood and non wood (gum rosin) products, planting by using superior or high quality seeds are needed. Seed procurements for planting are obtained from seedling seed orchard (SSO). However, Cijambu’s SSO was attacked by pine woolly aphid (Pineus boerneri). Therefore, assessment of Cijambu’s SSO needs to be done to evaluate the severity pest attacks that could affect to the quality and the quantity of seed production. Forest Health Monitoring (FHM) method is one of the methods to assess the health level of a stand. The number of trees found in all cluster plots in Cijambu’s SSO were 270 trees. Based on the value of the VCR (Visual Crown Rating), the trees located in all cluster plot have health level between low to high. Based on the value of the VCR showed 38.52% (104 trees) having VCR’s value was high, 49.26% (133 trees) having VCR’s value was middle; 12.22% (33 trees) having VCR’s value was low; and no tree having very low VCR’s value. The average of VCR’s value in all cluster plots were 3.25 and classified as middle health. Based on the value of TDLI (Tree Damage Level Index) from 270 trees in all cluster plot showed that 189 trees (70.00%) in healthy condition; 69 trees (25.56%) in slight damage condition; 11 trees (4.07%) in middle damage condition; and 1 tree (0.37%) in heavy damage condition. The value of damage in all cluster plots (ALI) was 261.22 and classified as in health condition. The trees located in all cluster plots were mostly suitable to be seed sources as 242 trees (89.63%), while 28 trees (10.37%) were not suitable for seed sources.Keywords: Forest Health Monitoring, Pinus merkusii, seedling seed orchard, Tree Damage Level Index, Visual Crown Rating
