“…ScFM is blamed to harvest green trees and controversy arose during the implementation of the program due to the high number of trees cut in comparison to passive management followed during the past; but actually it was found that ScFM helps to remove overmature, diseased, and decayed trees from the forest and helps to maintain the forest's health [18]. Heart rot can be very hard to prevent and control but can be avoided if a tree is carefully monitored over its entire lifetime [19] and the active management scheme of ScFM enhances the monitoring activities in comparison to passive management. e sustainable practice of harvesting can enhance forest's health and also maximize the benefit by reducing the overmature trees [20].…”

A significant volume of wood was lost due to wood defects; however, few studies were done to quantify wood loss by wood defects. This study was focused on quantifying wood loss by heart rot, especially hollowness in Shorea robusta. The study was conducted in Tileswornath community forest of Rautahat district. The data were collected from the felling site of the regeneration felling block of Tileswornath community forest. 44 trees were selected randomly, and tree diameter, total height, and volume were measured. The destructive method was followed as heart rot cannot be visible from the surface. Felled trees were sanctioned into 285 logs and separated based on the hollowness. Hollow diameters at both thin end and mid and thick end, as well as length, were measured on the hollow log, and Smalian’s formula was used to calculate the volume of hollowed portion, and volume calculation formula for the cylinder was used to calculate total volume. For the solid logs, mid diameter and length of the log were measured and volume calculation formula for the cylinder was used to calculate total volume. Logistic regression was performed to identify the relation of total height and diameter with the probability of hollowness presence. The study showed that 59% of sampled trees and 34.39% of logs were found to be hollowed due to heart rot. 41.79% volume was occupied by hollow on the hollowed log. Logistic regression discards the relation of height to the hollowness but signified the relation of diameter to the probability of hollowness presence. Before implementation of scientific forest management modality, the timber retained in stump per tree was found as 0.18 cubic feet.

“…Fungi deplete the tree's hemicellulose, cellulose, and, in some cases, lignin, resulting in the tree's death (Figure 6) (Tripathi and Adhikari, 2021). Symptoms: Heart rot is difficult to diagnose since it occurs internally and can go undetected for years (Jha, 2020). Mushrooms typically grow on the trunk or branch of a tree in the later stages of heart rot.…”

“…S. robusta was seriously affected by heart rot-causing fungi in Nepal, posing a serious problem because timber is one of the country's most important resources (Tripathi and Adhikari, 2021). There is no cost-effective fungicide that can be used in heart rot fungi (Jha, 2020).…”

Sal (Shorea robusta) is one of the most indispensable species in Nepal, both ecologically and economically. This paper aims to provide updated guidance for the management and protection of this species in the future from various pests and pathogens. We reviewed 38 articles from Google Scholar and Research gate with keywords "Shorea robusta”, “Hoplocerambyx spinicornis”, “Polyporus shoreae”, “Heart rot”. S. robusta has the most insect fauna among the forest tree species. Out of the 346 insects reported on S. robusta, around 155 species of insects are associated with living trees. Hoplocerambyx spinicornis is the most destructive insect pest, wreaking havoc on S. robusta. Polyporous shoreae is the main cause of root rot in S. robusta, and spreads through root contact or root grafting. Heart rot in S. robusta is caused by the fungi Hymenochaete rubiginosa, Fomes caryophylli, and F. fastuosus. During the harvesting of S. robusta, the majority of the tree was observed to be faulty, resulting in a large amount of waste wood. The best way to determine the pathogen's "Achilles' heel" is to consider its life cycle. The Nepalese famous saying "prevention is better than cure" may be applicable in the management of S. robusta insect pests and pathogens. The current paper critically addresses these issues and argues the need for an improvised package of activities for insect pests, pathogens, prevention, and their control.
