RANGE SYSTEMS STUDY OF RAMECHAP DISTRICT (THODUNG REGION) OF NEPAL S.M. Pradhan1, D. Pariyar, J.R. Adhikari and R.C. Ghimire ABSTRACT Ramechap district lies in the hill and mountain region of Nepal. Considerable portions of Ramechap district are at high elevation (1000—4848 m) towards the peak of the Himalayan range while the southern part comprises the lower elevation of the mid - hill region (700 m). Maize, wheat and fingermillet as cereal crops and potato as horticulture crop are cultivated in the lower belt bariland of high altitude pastoral system (2600 -3000 m) where as wheat, nacked barley or barley are major crops in upper belt (3000 -3800 m). Annual food dificit at high altitude region is severe and substantial number of population spend their time with animals in transhumane system and dependent on animal production for their survival. Overgrazing is the main problem at areas from 2600 - 3400 masl. but above that level the rangeland utilization is less than 50% due to harsh climatic condition and difficult access. Presence of toxic plant species like Anemone elongata (Jukabikh), Chlorophytum sp. (Choto), Pieris formosa (Bulu) may pose danger to the grazing animals. 1. INTRODUCTION Geophysically Remechap district lies in the Hill and Mountain rcuion of Nepal. It is situated at latitude 27°28” —27°50” and longitude 85°50” 86° 35”. It covers a total area of 1546 square kilometer. Out of this total the cultivated land covers 26.6% (40050 ha), non - cultivated land 12.7% (19130 ha), grazing land 8% (11429 ha), Forest land 44% (66152 ha) and other 8. 9% (13433 ha). The district is elevated from south (700 m) towards North (1000 - 4848 m). The climate varies with the elevation of the places from cool, temperate to alpine towards northern part. The average annual temperature is about 11.9°C and maximum is 21.3° The average annual precipitation in the district is 2025 mm. Livestock are an effective means of utilizing and providing added value to natural resource in producing human food and additional income. The incremental effect of livestock on output from a given agroecosvstem form their multipurpose and form positive interactions with soils and crops (Quereshi, 1992). The stock farming in the high altitude of Nepal faces severe hardships. Large number of animals are grazed in small grassland areas. Consequently, the condition of grasslands is poor. This is particularly true for the more accessible grassland which are exposed to continuous grazing by a large number of animals (Thapa, 1993). Annual food deficit to the entire population is estimated as 2.5% (NRA, 1997), being severe at high altitude regions. Therefore, substantial number of population of high altitude regions as well as herdsmen along with animal flocks spend their time in transhumane system for income and survivability. 2. OBJECTIVES The objectives of this study are: • • • • 1 To study the traditional pastoral system of the high altitude rangelands. To identify major constraints and problems of rearing chauri. To study productivity and condition of different pasturelands. To document the indigenous knowledge for maintenance and to sustain high altitude pastoral system. National Coordinator, Nepal Agricultural Research Council, Kathmandu, Nepal. 3. MATERIALS AND METHODS The study was conducted from interview of the herders, field survey and sample collection. Structured questionnaire was developed to record information on stopover, camping sites, duration of stay at different sites, animal types, their production systems and marketing of products. Similarly information were also recorded on grazing systems, range conditions, toxic plants, grazing rights and socioeconomic status. A standard format was dcvclopcd to collect the plant species found in different grazing lands. With the help of the herder grasses, legumes and forbes were identified in the field. The plant species samples were properly pressed and carricd to Kathmandu for botanical identification. A quadrat of tin 2 was randomly laid out in order to assess the biomass (above ground) production. Fresh weight was recorded after harvesting it at 2.5 cms above the ground and key species were recorded. The soil samples of about 1 kg. up to 20 ems. depth was collected from seven grazing lands for their analysis. For obtaining data on animal herd composition 58 herdsmen were contacted and for household size, literacy, cropping systems and crop production 19 herdsmen were interviewed. Clipping scissors, balance, measuring tape, altimeter, compass, plastic and paper bags, auger, marker pens and other important materials were used to take the field data. 3.1 Description of Grazinglands The rangelands of Thodung region of Ramechap District are located at altitudes from 2600 to 4000 masl. About 1300 chauries utilize the vast areas of grazing lands (Table 1). Rangelands upto 2800 masl are located in the vicinity of the forest and beyond it the rangeland are called as open grazingland. Table 1. Description of grazinglands of Thodung regions of Ramechap, 1999.

Available Phosphorous (P 205 kg/ha) in the soil was also low (14.2 -30.05 kg/ha). Full dose of phosphorus is needed to get optimum forage production from those grazingland. As in sailung rangeland (Shrestha & Pariyar, 1998) available potash and organic matter content is high. The soil texture varied from sandy loam to loamy sand. 3.2 Grazing route and stopovers Five district grazing routes are used by 60 herds of high altitude regions of Thodung region and the stopover! camping points are fixed for every route and herd (Table 2). Almost all the herds spend 4-6 months in Winter in the low altitude grazing lands (2600-2800 mast), 2-4 months in transitional zone while moving up in March to June and returning back in September and October at an altitude of 2900 - 3200 mast. In the grazinglands above 3300 mast. the duration of grazing shortens to about 1-3 months particularly in the months of June to August (Table 3.). In Far-Western Hills of Nepal also the farmers graze their animals in high altitude pastures from June! July to Septernber!October (Rajbhandary and Pradhan, 1981). Table 2.

Their herds were composed of 1279 chauries, 57 local breeding bulls, 78 goats and only 2 poultry birds. All the chauries in the herd were in milking which may be due to selling of unproductive animals for meat or other purpose in the Tibetan boarder. In contrast to herd composition of Sailung region of Ramechap district no sheep were reared and poultry was also negligible. On an average a herd was composed of 22 ehauries, 1 breeding bull and 1.3 goats. 3.4 Breeding and calving pattern The main breeding season for chauries is in summer (June - July) which was similar to that in Sailung region. Parturition takes place after 9 months which is generally in February-March. Though during this time there is shortage of feeds, but due to high price for off season production, the farmers prefer calving in dry season. The breeding bulls kept by farmers are of small size but are active for breeding use. Less problem of dystokia is faced by the farmers and rare case of abortion was observed. Incase of goats, 3 kidding in two years is common in high pastoral area whereas kidding twice a year is common in the lower belt of the region. 3.5 Health care and mortality in animals Occasional occurrence of Red water, Mastitis and Foot and mouth disease were reported. Locally available herbs are used to treat the animals. Pneumonia was the major problem in goat kids. Some casualties were reported in chauries due to falling from steep mountain slopes and the meat is shared by the herders. 3.6 Livestock Products 3.6.1 Milk Sale of raw milk is the main source of income to the farmers. Both the Dairy processing plants (Dairy Development Corporation and private Dairy) have 3 collection centres each with permanent infrastructures at different altitudes. The herders have to walk not more than two hours to supply their milk to the collection centres. Average milk production from a chauri in 270 days lactation period was estimated to be 630 litres. The milk production was around 3 litres/day during April-May and increases upto 4-5 litres/day during June-August Which drops down to 1-1.5 litres/ day in September-December. The farmers get gross benefit of NRs. 2,07,900 per year from a average herd of 22 chauries only by selling milk at the rate of NRs. 1 5/Litre. Supposing fifty percent of the income is spent on feed, medicine and management, a farmer’s family get net benefit of NRs. 1,03,950 per year from their herd. 3.6.2 Animal sale and purchase Herders purchase 1 to 1.5 years old young hcifers to replenish their herd from Namche bazar and khumjung areas of Solukhumbu district. The heifers are mated at about 3 years of age and give first calve around the age of 4 years. A chauri is kept for 9-1&’ lactation. Generally the milk production drops down from 9th lactation. So the herders sell their chauries after S “‘ lactation to Tibetan traders. Tibetan traders occasionally come to buy the animals. A few herders practice buying young stock at 1.5 years of age for NRs. 3000-4000 and rear them upto the age of 6 years or second lactation and sell at the price of NRs. 15,000-20,000 for a chauri. 3.6.3 Hair and chamar None of the herders reported harvesting hair from chauri but the chamar (Tail part) of dead chauri is sold for performing religious ceremony. A chamar fetches NRs. 200-800 according to color of the chamar. Whitish color fetches maximum price followed by mixed (white and black) and brown colour. 3.6.4 Manures There is the practice of manures collection and storing in the major grazing lands up to height of 3200 masl. Above this height it is difficult to collect, store and carry manures to the bariland. They pile the manures at different places of the major grazing land and carry to the higher areas in dried form only. They carry the dried dungs in sacks or Thumse. Large amount of dry manures are put inside a pit to decompose it for a month and use for the cultivation of crops in bariland at high altitudes. 3.6.5 Hides The hides of chauri is used for bedding. 3.6.6 Marketing There is no problem of marketing as such. Fresh raw milk is sold to Dairy Development corporation and three private cheese factories. The herders have to carry the milk to the collection centres by walking a distance of not more than two hours. Most of the milk is processed to make cheese, which have good market in Kathmandu as well as trekkers and expedition groups going to Solukhumbu. 3.7 Feeding and Grazing Over 60 herders rear the ruminants solely on available forage from the grazing lands in transhumane system of grazing. These herds are moved upwards ahd downwards through five district routes and utilize the biomass through rotational grazing system. Chauries are provided 50-100 gins of salt per day and maize flour is provided to the chauries during the calving and after calving for about 2 weeks. Some weak chauries are also provided maize flour. In a year about 11 kg (5 Pathi) maize flour is provided to a chauri. Medicines are hardly used only during difficult times. The herders opinion and system of grazing is different in Thodung than from sailung area. In their opinion sheep graze to the surface like chauries and there is competition for nutrition and palatable grasses, forbes and legumes if they rear sheep. The herdsmen prefer goat to sheep for the reason that they are browsers and do not compete with chauries for feed. The herders also believe that the chauries do not graze in the particular area already grazed by sheep due to the odor or bad smell of urine and dropping of sheep. The herdsmen graze goats only up to 3200 masl. 3.8 Fodder trees The practice of feeding leaves and twigs of fodder trees are rare in high altitude. Leaves and twigs of Arundinaria sp. (Shrub) and Ouercus semicarpzfolia (tree) which are found upto the height of 3100 masl is fed to the animals for about 10 days after calving. The annual production of fodder from a Qyercus semicarpzfolia tree and Arundinaria sp. shrub is 30 kg. and 8-10 kg. respectively 3.9 Botanical composition and biomass production A total of 63 native and naturalized plants species have been collected and 30 were identified as forbes, 15 as grass, 8 as shrub, 4 as tree, one as legume and five species not identified in Thodung region (Table 4). The species which were not identified was due to poor samples. Trifolium repens c.v. Huia which was introduced during 1974-75 was the only legume specie in that area. In some of the stopover place white clover is still growing well because of rotational grazing. Three samples each from nine randomly selected grazing lands situated at an altitudes of 2800, 3100 and 3300 masl were taken using 1m2 quadrant to record avenge biomass yield. From an altitude of 2800 to 3300 masl, not much difference in vegetation was found . The predominant species found at 3300 masl were Danthonia sp., Pogonatherum paniceum and Anaphalis cornorta. The productivity of the green matter (GM) was recorded to be 0.5 U’ ha in the first cut in May-June, 1999. From three cuts that could be taken in the growing season of May-August, the average yield per hectare was estimated at 1.5 t. In the open grazing lands at 3170 masl the dominant species were found to be Danthania sp., Pogonatherutn paniceum, Tr:fo/ium repens and mixture of other species produce almost 2.8t/ha. However in the fenced area, the dominant species were found to be Dan (hon/a sp., Pogonadierum pan/ce urn, Trrfoliurn repens, call/ia palunri, anaphahs con(orta and Gal/urn aparine and the yield was 7.0 ton per hectare. In the lower altitude rangelands of Deuralil Yaknagi, where Anaphalis contorta, Pogonatherum paniceurn, Anaphal/s rnargaritacea were dominant have produced 2.4 ton per hectare GM production The vegetation coverage increased with the increase in elevation. The vegetation coverage in the grazing lands around 2800 mast was 40-70%, at 3170 masl. was 60-70% and at 3300 masl. it was 70-90%. Table 4. 3.10 Toxic species and serious weeds There was an acute problem of toxic plants in the grazing lands of Thodung area where as in Sailung area there was no problem like this(Shrestha and Pariyar, 1998). Anemone elogata (Jukabikh), chorophytum sp. (Choto) and Pieris formosa (BuIu) are the main toxic plants.. Chorophytum sp. was rated highly toxic in comparision to Anemona elongata and Pierisformosa. Chauries and goats die within shor period of two hours if they graze on chlorophytum sp. and no antidote was known locally to the herders. Chlorophytum sp. are more fatal to new and young stock because they graze the tender parts of chlorophytum sp. due to lack of, selcctivity of species in the begining chlorophytum sp. at younger stage is more poisonous than old and semi-dried plants. Chlorophytum sp. coverage of grazing land is growing at a faster rate and farmers demanded an effective program to eradicate this species. Rarely any animal has died by consuming Anemone elongata and Pieris formosa but it causes production loss for some days due to bloating and indigestion in the ruminants. 3.11 Range condition The condition of rangeland was poor to medium. Over grazing was a common problem in low altitude areas (2600-2800 masl) due to grazing of animals from lower belt as well as higher hills and longer stay of almost six months. Due to favorable climatic condition, easy access and easy stay the herds stay for longer duration (8-10 months) in the lower belt grazing lands (2600-3400 masl) and the vegetation utilization is over 90% upto Thodung (route 1 and 2), Phokte (route 3) Koshi kharka (route 4.) and Serding (route 5).

Rajbhandary and Pradhan (1981) also reported under utilization of alpine pasture to the extent of 45% only. Herds stay in these area for shorter duration (2-3 months) due to harsh climate, difficult access and stay. The Village Development Committee (VDC) have facilitated the herders by constructing trail and drinking water facilities for which they have to contribute Rs. 500 -1000 per herd to the respective VDC's. 3.12 Grazing rights Traditional demarcation for the use of grazing areas are still maintained. The herds of Thodung (Ramechap) region utilize grazing lands of chuchure VDC, Bamti VDC and Gumdel VDC. No specific grazing rights system exists except to the traditional utilization law, which has fixed five routes and has identified the herdcrs for utilizing grazing lands. 3.13 Socio-economic status The average family size of herders was 5.3 of which 52% were female and 48% were males. The literacy rate in males was 26% and that in females was 18%.j| On an average of 19 herdsmen, 1.27 ha (25.4 Ropanis) of cultivated uplands is owned by each family. For lower belt bariland (2600-3000 masl.) of high altitude pastoral system Maize, Wheat and Fingermillet were major cereal crops and Potato as vegetable crop. They produce two crops in 1.5 year and their cropping pattern was rotational. Incase of higher altitude bariland (3000-3800 masl) they cultivate one crop in a year. Wheat, Nacked barley, and Barley arc major cereal crops and Potato vegetable crop. The cropping pattern in rotational system is. Only 18% requirement of food crops of the total family is met by their production. The people in those areas need income generating activities to sustain their life and which may be main reason that the people living in that are attracted towards chauri farming. 3.14 Constraints • Toxic plants: Invasion of rangelands by toxic plants like Anemone elongata (Jukabikh), chlorophytum sp. (Choto) and Pieris formosa (Bulu) is the major concern to the herders. • Overgrazing: Overgrazing in the areas upto 2900 masl was one of the other major problems to chauri herders. • Low productivity of Rangeland: Although there were large number of grazing land, the productivity was very poor, which may be due to less coverage by legumes and low production from available native species. Low production from native species may be due to lack of protection oftliese species and overgrazing by large number of animals with resulting in loss of soil fertility. • Diseases: Red water. Mastitis, Foot and months disease and Pneumonia cause health hazards into the flocks. 3.15 Suggestion by herders and an outline for future activities An effective initiative should be taken by Government agencies to eradicate the toxic plants in the grazing fields. • An orientation program or training should be organized to create awareness among the herders to make them able to manage the rangeland effectively. • A study should be carried out with high yielding native species as well as less fertilizer demanding improved species through participatory approach of Research, extension and users group. • The herders should be provided opportunities to qualify for semi-skilled technician by providing training in animal health care and management. 4.
