Byers A reconnaissance of the upper Hinku valley, the use of kerosene as a fuel substitute for Makalu-Barun National Park and Buffer alpine shrubs, and attempted to limit the Zone, Nepal was undertaken in May, 2007 number of new lodges that could be built in to determine the impacts of contemporary the valley. Repeat sampling of alpine hillslopes adventure tourism upon its subalpine and suggest that these actions have had significant alpine ecosystems. Results showed that visitor conservation benefits. However, it is clear numbers, lodges, and other tourist-related that the challenges of promoting high altitude infrastructure grew from one structure in 1995 conservation, and of finding renewable, to 129 in 2007. This growth was accompanied sustainable energy sources alternative to by a corresponding and accelerated harvesting alpine shrubs and kerosene, will remain for of subalpine timber for lodge construction, the foreseeable future. Strategies that could and of shrub juniper and dwarf rhododendron facilitate beneficial change in current alpine for use as fuel in alpine tourist lodges. These usage practices are discussed in the paper. practices were largely discontinued with the Keywords: Himalaya, Nepal, adventure tourism, alpine, formation of the Mera Alpine Conservation subalpine. Group (MACG) in 2008, which placed greater restrictions on timber harvesting, mandated HIMALAYA Volume 33, Numbers 1 & 2 | 25 Introduction was found to be linked to the unsustainable harvesting of alpine shrubs by lodges, climbing teams, trekking parties, Alpine ecosystems cover three percent of the earth’s land and porters to satisfy their fuelwood (for cooking and surface and contain over 10,000 species of plants. Among heating) and puja (ceremonial) requirements, which in the most biodiverse ecosystems per unit area in the world turn was responsible for the loss of an estimated 70,000 (Körner 1999), they are of critical importance as sources kilograms of shrub juniper per year from the hillslopes of freshwater (Bandyopadhay et. al 1997), medicinal and surrounding the Pheriche, Dingboche, and Chukung aromatic plants (Olsen and Larsen 2003; Buntane et al. settlements (Byers 2001, 2005). The accelerated harvesting 2006; Cox 2008), and as integral parts of high mountain of alpine cushion plants for fuel (especially Arenaria livelihoods that are increasingly becoming dependent on spp.) and dwarf rhododendron spp. (e.g., Rhododendron the adventure tourism trade (Godde et al. 2000; Nepal 2000; anthropogon, R. setosum), was also documented. This was Nepal et al. 2002). of particular concern because all of these plants have Alpine ecosystems throughout the mountain world have extremely slow growth rates, for example, a 5 cm-diameter been heavily altered by human activities, especially shrub juniper cross section collected near Chukung and during the past 20 to 30 years with the substantial growth analyzed by the Columbia University Tree Ring Laboratory of mountaineering, trekking, and adventure tourism to showed an age of 157 years (Krusic pers. comm. 2007). remote mountain regions (Nagy and Grabherr 2009: 299- Collectively, these disturbances appeared to be creating 302; Byers 2005). The most common impacts include the high altitude wastelands throughout much of the upper removal of slow growing alpine shrubs and cushion plants Imja khola (river) watershed (see Byers 2005: 127-136), by lodge owners, porters, and climbing/trekking parties including accelerated soil loss processes that were for use as fuel (Stevens 2003; Byers 2001, 2005). The recent estimated to exceed 40 metric tons/ha/yr (Byers 1987b: growth in the uncontrolled harvesting of the medicinal 169). National park enforcement of existing conservation plant yarsagumba (Cordyceps sinensis) has placed additional regulations was largely absent at the time for reasons stresses on alpine ecosystems in Nepal and elsewhere (Cox that are not entirely understood. I have observed similar 2008). Associated accelerations in soil loss and decreased processes occurring around many of the world’s iconic slope stability often result from the indiscriminate mountain landscapes that have experienced significant removal of these soil-binding shrubs (Byers 1987b, 1997, growth in tourist traffic over the past several decades, 2005; Körner 1999). Other forms of disturbance include including Everest (China and Nepal sides), Makalu, turf cutting (Byers 1987b, 2005; Olsen and Larsen 2003); Kanchendzunga, Kilimanjaro, Mt. Kenya, Huascarán, the increased numbers of pack animals (yak and dzopio in the Russian and Mongolian Altai, and others. Himalayas, burros and cattle in the Andes) to accommodate In 2004, The Mountain Institute (TMI) and American growing numbers of tourists (Byers 2005, 2011; Pérez Alpine Club (AAC) established the Alpine Conservation 1998); accelerated water borne health hazards as a result Partnership (ACP).

Community consultations are then held Sagarmatha (Mt. Everest) National Park (SNP) region in to discuss the findings, and to gauge local interest in the mid-1980s (see: 1987a, 1987b, 19897c), followed by forming an alpine conservation council or committee that more detailed work from 1995 to the present (see: Byers works in partnership with national park authorities to 2001, 2005: 127-131; this paper). Collectively, the results develop a series of conservation and alternative energy of my field investigations revealed that a heavy loss of interventions. Seed funding is provided in support of shrub juniper (Juniperus indica) and other alpine plants had activities approved by the alpine conservation committees occurred along the traditional Everest basecamp route for the first year or two, with the understanding that since the opening of the region to adventure travel in the the committees agree to be financially independent by early 1950s (Schneider 1963; Hillary 1999).
