Pine Resin Trapping in Himachal Pradesh

Solan-In the past decade, intensive resin tapping by rill method has resulted in the drying of thousands of pine trees in Himachal Pradesh. It has also been observed, that the application of higher concentration of acid, used as a freshener, had adversely affected the growth of trees and even the tapped surface area is not healing.

Therefore, the HP State Forest Development Corporation will soon adopt the borehole technique of oleoresin extraction to minimize the damage caused to pine trees by resin tapping and simultaneously increase the quality of the collected resin.

It was informed by Himachal Pradesh Forest Minister Sh. Gobind Singh Thakur during the concluding session of the one-day training of officials from HP State Forest Development Corporation at the Dr YS Parmar University of Horticulture and Forestry (UHF) Nauni. The method has been developed by the scientists of the Forest Products Department of the university.

The Forest Minister said that the department would adopt the new technique in the coming time so that the twin motives of resin quality and its quantity along with ensuring the good health of the trees can be met. He said that the Forest Department will work in collaboration with the university so that the benefit of the various technologies developed by it can be put to the best use for the development of the state.

BD Suyal, MD State Forest Corporation said that technique is quite encouraging and the corporation will take up setting up 10-15,000 bores in every directorate to assess the results of the method. He added that in the second phase the contractors and the labourers will be also be trained on technique by the university. Earlier, Dr Kulwant Rai Sharma gave a detailed presentation and practical demonstration on the technique to the forest officials. He said that the adoption of the technology can prove to be boon for the forests and the resin industry. 

What is Borehole Method of Resin Extraction  

The new method involves drilling small holes (1 inch wide and 4 inches deep) with the help of simple tools into the tree to open its resin ducts. The holes are drilled with a slight slope towards the opening, so that oleoresin drains freely. Multiple boreholes are arrayed evenly around the tree’s circumference, or clustered in groups of two or three. Spouts are tightly fitted into the opening with polythene bags attached to it with the help of tie for resin collection.

Borehole Resin Extraction’ Method

The new technique was developed in an attempt to overcome some of the limitations of other conventional methods. A key feature of the method is that a closed collection apparatus prevents premature solidification of resin acids, thereby maintaining oleoresin flow for an extended period of up to six months. Due to reduced oxidation and contamination, the end product is of higher quality with substantially higher turpentine. The average yield per tree is almost the same if numbers of boreholes on a tree are adjusted as per the maximum carrying capacity of the tree. The method also allows tapping of lower diameter trees depending upon their potential of production without having any impact on their health. The crown fire hazards incidents are also less because there is no hard resin accumulation on the main stem and spread of ground blaze can be easily avoided by removing the bags well in time.

The rosin and turpentine oil obtained from borehole method are of very good quality, which can fetch higher prices in the market. In addition to tackling the problems of tree health, labour requirements and costs for borehole tapping are significantly lower than conventional methods. The borehole wounds cause little damage to the tree bark and since these holes are near the ground level, only a healed scar can be seen in the converted woods. Therefore, there is no damage to the merchantable part of the tree.

Further, the Forest Minister also said that the university and the forest department will look to work together for establishing an eco-tourism model on the university campus. He added that the University Vice-Chancellor will be invited to all the important policy meetings of the state forest department to seek their expertise. The forest minister visited the demonstration block of borehole technique and also planted a tree at the university.

UHF Vice-Chancellor Dr Parvinder Kaushal called for continuous interaction between the university and the forest department. He emphasized on apprising the grass root level workers and train them on the new technique.

The event was attended by  BD Suyal, Managing Director, HP Forest Corporation; KK Kataik Director(South); Dr JN Sharma, Director Research, Dr Kulwant Rai Dean College of Forestry and other officials of the university. Around 30 officers of the rank of Divisional Managers and Assistant Managers from various parts of the state took part in the training.

helpline for Forest Fires in himachal pradesh

Shimla-Forest fire is a recurrent annual phenomenon in Himachal Pradesh and causes losses worth several crores every year. Dry spell and summers make forests, especially chir pine forests, highly vulnerable to forest fires. These forest fires not only damage the forest wealth but also hit wildlife and biodiversity in general. The forest department attributes most fires to human factors.

Like every year, the forest department has claimed that it is all geared up and ready to combat forest fires this year too. Principal Chief Conservator of Forests Dr. Savita on Monday held a virtual review meeting with Forest Circles on preparedness for forest fires in the state.

She said that the Forest department was well prepared to fight the forest fires and a rapid forest fire fighting force and rapid response teams had been set up at forest division and range levels.

“Approximately 40,000 man-days of fire watchers would be engaged by the department in addition to existing frontline staff for preventing and combating forest fires,” she said. The state disaster control room with toll-free number 1077 at the state level and 1070 at the district level were operational for reporting of the forest fire by the local community, she informed.

Dr. Savita said messages regarding forest fire had been shared with the members of the rapid forest fire fighting force, in which approximately 50,000 volunteers had already been registered. Awareness to the community was also conducted through Nukkar Nataks, songs, speeches and other activities at different locations in the state. Besides, a massive state-level awareness program was also conducted at 45 places from 10 to 17 March 2021

She said that the department had created forest fire lines and did control burning and also constructed water storage structures in the forest areas to combat forest fires. Additional multi-utility vehicles and water loaded tankers in 80 fire-sensitive ranges had been engaged for three months. She that matter regarding Standard Operating Systems (SOPs) for requisition of helicopter services for dousing the forest fires had been sent to the Government for approval.

Annual Bird Count in Himachal Pradesh 2021

Shimla-The habitat of migratory and resident water-birds in Himachal Pradesh has gradually improved, said Forest Minister Rakesh Pathania.

The annual water-bird count at Pong Dam Lake Wildlife Sanctuary was conducted in the first of February, 2021 and the exercise was conducted under restrained conditions due to the prevailing Avian Influenza outbreak in Pong Dam Lake as well as the COVID-19 Pandemic, he said.

The exercise was conducted by Wildlife wing of Himachal Pradesh by deploying 57 staff members in 26 sections of the sanctuary for counting the water-dependent birds.

Total 108,578 birds of 96 species were counted during this year. Out of the total number, 101,431 of 51 species are water-dependent migratory birds and 6,433 of 29 species are water-dependent resident birds. As many as 714 birds of 16 other species were also recorded. The total population of the flagship species, Bar-Headed Geese, is 40,570.

The other species which have higher population count during this year are Eurasian Coot (24,163), Northern Pintail (12,702), Common Teal (8,444), Little Cormorant (3,649), Great Cormorant (3,410), Grey Lag Goose (2,297), Northern Shoveler (2,275) and Common Pochard (2,138). The species which find noticeable mention are Red Necked Grebe, Great Bittern, Lesser White-Fronted Goose, Red Crested Pochard, Ferruginous Pochard, Pied Avocet, Northern Lapwing, Peregrine Falcon etc. During the counting exercise, one Bar-headed Goose and one Grey Lag Goose with collars were also spotted.

This year the Annual bird count exercise assumes significance, considering the Avian Influenza outbreak in the Wildlife Sanctuary. Further, the Minister expressed satisfaction over the timely and effective containment measures taken by Wildlife Wing to control and contain Avian Influenza outbreak in the Wildlife Sanctuary.

PCCF (Wildlife) Archana Sharma and CCF Wildlife (North) Dharamshala Upasana Patial also participated and supervised the Annual Water Bird Count.

The total population of birds, as well as number of species, counted this year are marginally less as compared to last year, probably due to the impact of Avian Influenza outbreak which was first reported on 28th December 2020.

Although the total population of water birds declined during the peak of the Avian Influenza outbreak, there is a gradual increase in the total population of birds, the Minister informed.

Himachal First State to Complete Assessment of Snow Leopard and its Wild Prey

Snow Leopard Population Assessment in Himachal Pradesh

Shimla-The assessment of snow leopard population in Himachal Pradesh has been completed by the state wildlife wing in collaboration with Nature Conservation Foundation (NCF) Bangalore following the protocol aligning with the SPAI (Snow Leopard Population Assessment in India) protocols of the Ministry of Environment, Forests and Climate Change. Himachal Pradesh has become the first state to complete assessment of snow leopard and its wild prey.

The state has an estimated population of up to 73 snow leopards.

It is the first scientifically robust estimate of snow leopards and its prey for the State. Since snow leopard is the state animal, the study assumes great significance for Himachal Pradesh.
The exercise revealed that snow leopard density ranged from 0.08 to 0.37 individuals per 100 sq.km., with the trans-Himalayan regions of Spiti, Pin valley and upper Kinnaur recording the highest densities, both of the predator and its prey, mainly ibex and blue sheep.

This study covered the entire potential snow leopard habitat of Himachal Pradesh: an area of 26,112 sq.km., utilising a stratified sampling design. Camera trapping surveys were conducted at 10 sites to representatively sample all the strata i.e. high, low and unknown. The camera trap deployment over the mountainous terrains was led by a team of eight local youth of Kibber village and more than 70 frontline staff of HPFD were trained in this technique as part of the project. Snow leopards were detected at all the 10 sites (Bhaga, Chandra, Bharmour, Kullu, Miyar, Pin, Baspa, Tabo, Hangrang & Spiti) suggesting that snow leopards are found in the entire snow leopard habitat in Himachal Pradesh either as resident individuals of a population or as dispersing individuals navigating through these connecting habitats.

Another revelation from the study is that a bulk of snow leopard occurrence is outside protected areas, reiterating the fact that local communities are the strongest allies for conservation in snow leopard landscapes.

The NCF and wildlife wing collaborated in the effort and it took three years to complete the assessment. MoEFCC had launched the First National Protocol on Snow Leopard Population Assessment in India, on the occasion of International Snow Leopard Day. You can read the complete protocol here.

Snow leopard is the icon of high mountains of Asia. In India, they inhabit the higher Himalayan and TransHimalayan landscape in an altitudinal range between approximately 3,000 m to 5,400 m above MSL, spanning c. 100,000 km2 in the five states of Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Sikkim and Arunachal Pradesh. This area contributes to about 5% of the global snow leopard range.

Snow leopards occur over a vast, relatively remote and difficult to access mountainous area. Together with their elusive nature, this makes a complete population census of snow leopards an unfeasible goal. Even their distribution remains unclear. For example, recent surveys show that they do not occur in 25 % of the area that was thought to be their range in the state of Himachal Pradesh Their density is expected to be variable in space, dependent on several factors such as habitat suitability, prey availability, disturbance and connectivity. Variation in density across space also poses the risk of biased sampling, and, indeed, most of the snow leopard population assessments conducted so far across the world are biased towards the best habitats.
