An Introduction to the Bofedales of the Peruvian High Andes
An introduction to the bofedales of the Peruvian High Andes M.S. Maldonado Fonkén International Mire Conservation Group, Lima, Peru _______________________________________________________________________________________ SUMMARY In Peru, the term “bofedales” is used to describe areas of wetland vegetation that may have underlying peat layers. These areas are a key resource for traditional land management at high altitude. Because they retain water in the upper basins of the cordillera, they are important sources of water and forage for domesticated livestock as well as biodiversity hotspots. This article is based on more than six years’ work on bofedales in several regions of Peru. The concept of bofedal is introduced, the typical plant communities are identified and the associated wild mammals, birds and amphibians are described. Also, the most recent studies of peat and carbon storage in bofedales are reviewed. Traditional land use since prehispanic times has involved the management of water and livestock, both of which are essential for maintenance of these ecosystems. The status of bofedales in Peruvian legislation and their representation in natural protected areas and Ramsar sites is outlined. Finally, the main threats to their conservation (overgrazing, peat extraction, mining and development of infrastructure) are identified. KEY WORDS: cushion bog, high-altitude peat; land management; Peru; tropical peatland; wetland _______________________________________________________________________________________ INTRODUCTION organic soil or peat and a year-round green appearance which contrasts with the yellow of the The Tropical Andes Cordillera has a complex drier land that surrounds them.

Centre-Ville, Montréal, Québec, Canada 3current address: Geography, College of Life and Environmental Sciences, University of Exeter, UK _______________________________________________________________________________________ SUMMARY Peatlands have been widely studied in terms of their ecohydrology, carbon dynamics, ecosystem services and palaeoenvironmental archives. However, several assumptions are frequently made about peatlands in the academic literature, practitioner reports and the popular media which are either ambiguous or in some cases incorrect. Here we discuss the following ten common assumptions about peatlands: 1. the northern peatland carbon store will shrink under a warming climate; 2. peatlands are fragile ecosystems; 3. wet peatlands have greater rates of net carbon accumulation; 4. different rules apply to tropical peatlands; 5. peat is a single soil type; 6. peatlands behave like sponges; 7. Sphagnum is the main ‘ecosystem engineer’ in peatlands; 8. a single core provides a representative palaeo-archive from a peatland; 9. water-table reconstructions from peatlands provide direct records of past climate change; and 10. restoration of peatlands results in the re-establishment of their carbon sink function. In each case we consider the evidence supporting the assumption and, where appropriate, identify its shortcomings or ways in which it may be misleading. -

Glossary Ablation Till: Till Carried on Or Near the Surface of a Glacial Ice Column and Let Down As the Glacier Melted and Retreated
Glossary ablation till: till carried on or near the surface of a glacial ice column and let down as the glacier melted and retreated. alluvium: any mineral or detrital sediment that is transported and deposited by the flowing water of a river or stream. Riverbeds, floodplains, and deltas are all made up of alluvium. backswamp: low-lying wet areas on river floodplains, located away from the active river channel. basal till: till carried in the base of a glacial ice column and deposited under the glacier. Basal till is therefore very dense and typically forms a layer that impedes drainage. biological diversity (biodiversity): the complexity of all life at all its levels of organization, including genetic variability within species, species and species interac- tions, ecological processes, and the distribution of species and natural communities across the landscape. bog: an acidic, peat-accumulating wetland that is isolated from mineral-rich water sources by deep peat accumulation and therefore receives most of its water and nutri- ents from precipitation. Bogs are dominated by sphagnum moss and heath family shrubs. boreal forest: a circumpolar band of northern forests bordered to the north by open tundra and to the south by more transitional forests. Boreal forests are characterized by species of pine, spruce, fir, tamarack, birch, and poplar that are adapted to the extreme cold of this region. bryophyte: a division of plants including the mosses, liverworts, and hornworts. calciphile: a plant that thrives in calcium-rich soils. circumneutral: having a pH near 7.0 and therefore neither strongly acidic nor basic. cliff: an exposed, steep face of rock. -
Legal Protection Assessment of Different Inland Wetlands in Chile Patricia Möller1,2* and Andrés Muñoz-Pedreros3
Möller and Muñoz-Pedreros Revista Chilena de Historia Natural 2014, 87:23 http://www.revchilhistnat.com/content/87/1/23 RESEARCH Open Access Legal protection assessment of different inland wetlands in Chile Patricia Möller1,2* and Andrés Muñoz-Pedreros3 Abstract Background: Inland wetlands are well represented ecosystems in Chile that are subjected to various pressures affecting conservation. Protection means legal and administrative initiatives which promote the protection and/or preservation of a wetland, either in its entirety, considering their areas of influence or its components. Results: The aim of this work is to develop a methodology for estimating the value of protection of different types of inland wetlands in Chile. For this purpose: a) the Chilean regulations in relation to the issues of biodiversity, wetlands and water resources were compiled; (b) such legislation and its application were analyzed, (c) protection and restriction values of each legal standard was estimated, and then total protection value of standards applied to six types of wetlands in study. 47 legal rules related to protection of inland wetlands and eight directly or indirectly affecting conservation and wise use of wetlands were identified. Conclusions: In Chile there is no specific statutory rules or regulations on wetlands. Current legal standards do not protect equally the different types of inland wetlands, being swamp forests, peatlands and brackish Andean lakes less protected. To improve wetlands conservation, incentives promoting wetlands destruction must be eliminated and promulgate specific regulations for proper management and conservation. Keywords: Inland wetlands; Legal standards; Real protection; Wetland protection Background Wetlands support high biodiversity and are presently Chile is highly diverse in limnic systems mostly recog- recognized as the most threatened systems by human nized as wetlands and defined as ‘areas of marsh, fen, activities (Marín et al. -

The Effects of Check Dams and Other Erosion Control Structures on the Restoration of Andean Bofedal Ecosystems Brett D
RESEARCH ARTICLE The effects of check dams and other erosion control structures on the restoration of Andean bofedal ecosystems Brett D. Hartman1,2, Bodo Bookhagen1,3, Oliver A. Chadwick4 Restoring degraded lands in rural environments that are heavily managed to meet subsistence needs is a challenge due to high rates of disturbance and resource extraction. This study investigates the effcacy of erosion control structures (ECSs) as restoration tools in the context of a watershed rehabilitation and wet meadow (bofedal) restoration program in the Bolivian Andes. In an effort to enhance water security and increase grazing stability, Aymara indigenous communities built over 15,000 check dams, 9,100 terraces, 5,300 infltration ditches, and 35 pasture improvement trials. Communities built ECSs at different rates, and we compared vegetation change in the highest restoration management intensity, lowest restoration management intensity, and nonproject control communities. We used line transects to measure changes in vegetation cover and standing water in gullies with check dams and without check dams, and related these ground measurements to a time series (1986–2009) of normalized difference vegetation index derived from Landsat TM5 images. Evidence suggests that check dams increase bofedal vegetation and standing water at a local scale, and lead to increased greenness at a basin scale when combined with other ECSs. Watershed rehabilitation enhances ecosystem services signifcant to local communities (grazing stability, water security), which creates important synergies when conducting land restoration in rural development settings.

Vegetation of Andean Wetlands (Bofedales) in Huascarán National Park, Peru
Vegetation of Andean wetlands (bofedales) in Huascarán National Park, Peru M.H. Polk1, K.R. Young1, A. Cano2 and B. León1,2 1Department of Geography & the Environment, The University of Texas at Austin, USA 2Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima, Perú _______________________________________________________________________________________ SUMMARY Hybrid terrestrial-aquatic ecosystems in the Andes, commonly known as bofedales, consist of both peatlands and wet meadows and line valley floors at elevations > 3800 m. Compared with similar ecosystems at lower altitudes and higher latitudes, the ecosystem processes and spatial patterns of bofedales are only just beginning to be understood. The research presented here provides the first exploratory and descriptive analysis of the biodiversity and place-to-place variation of vegetation in bofedales in three valleys inside Peru’s Huascarán National Park. Through vegetation surveys, we recorded 112 plant species in 29 families. Over a short geographical distance, a valley-to-valley comparison showed high dissimilarity in terms of species composition. Based on dominant life form and species composition, vegetation in bofedales can be grouped into five assemblages. Our preliminary analysis suggests that several abiotic factors could influence the floristic composition of bofedales: elevation, bulk density, percent organic matter, and cation exchange capacity. The findings of high valley-to-valley variation in species, soil and elevation influences may be useful to land managers of high mountain landscapes that are undergoing transformation related to glacier recession. While our findings advance research on tropical Andean bofedales, they also highlight the need for additional comprehensive investigations to fill gaps in knowledge about the tropical mountains of Latin America.
