Little published information is available on the vegetation or its response to grazing in the high elevation (3,900-4,SOOm) grasslands ofthe Andes, known as the pun. The objective of this study was to evaluate grazing-induced vegetation changes on a major range site in the puma. Basal cow and diversity were compared on (1) rangelands managed by a coopentive of land holders (moderate grazing); (2) communal grazing land (heavy grazing); and (3) sacrifice or holding pastures (very heavy grazing). Basal cover was determined using point transects. With increased grazing pressure standing height of the vegetation was greatly reduced as was vegetstion basal cwer. Total cover of grasses was reduced while forb corer increased. Ability of a species to grow close to the soil surface probably enabled it to tolerate very heavy grazing. Species diversity as determined by Simpson's D, Shannon-Weaver's H', and species richness was highest on the community lands.

“…occurring between July and August. According to numerous studies on the phenological stages of F. dolichophylla (Choque, 2015;Flores, 2017;Florez et al, 1985;Gonzalez, 2017;Guillen, 2021), shows its highest daily production (5.3 kg ha −1 day) during this period and provides excellent nutritional value for domestic cattle and wildlife. Moreover, F. dolichophylla attains its peak crude protein content, ash, and organic compounds during this time (Tables 2 and 3; Choque, 2015;Florez et al, 1985;Gonzalez, 2017;Mamani-Linares & Cayo-Rojas, 2021).…”

“…By mid-April, when temperatures start to decrease in the Andes, mature seeds (caryopsis covered by the lemma and palea) of F. dolichophylla are ready to detach from the plant (seed shatter stage), and daily DM production declines to 3.8 kg ha −1 day (Choque, 2015;Florez et al, 1985).…”

This account provides information on all aspects of the biology of Festuca dolichophylla J. Presl (Chilliwa, Chilligua) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the International Biological Flora including distribution, habitat, communities, responses to biotic and environmental factors, structure and physiology, phenology, floral and seed characters, herbivores and disease, history, conservation and global heterogeneity. Festuca dolichophylla is a tall perennial tussock grass that thrives at high elevations. It is native and widely distributed along the Andes of South America. It also occurs in North and Central America, especially in Mexico and Costa Rica. Festuca dolichophylla plays a significant role in Andean ecosystems and communities of Ecuador, Perú, Bolivia and northern Argentina. It serves various purposes, primarily as food source for South American camelids such as llama and alpaca. Festuca dolichophylla is dominant in Altiplano (Andean high plains) grasslands and is also present in Bofedales (Andean peatlands), shrublands and possibly in Ecuador and Colombia paramos. Festuca dolichophylla reproduces through seeds and vegetative tillers. Flowering tillers bear panicles with multiple spikelets and florets. An ungrazed plant can produce as much as 15.6 g of seeds during May and June, and seeds can germinate in 7 days or more. Festuca dolichophylla exhibits physiological and ecological traits that enable it to thrive in harsh environmental conditions, including extreme temperatures, drought and nutrient‐poor soils. It thrives in a range of soil types from strongly acid to slightly alkaline, encompassing textures that include loamy, sandy clay loam, clay loam and clay, and which are influenced by the cold and semiarid Andean climate. Fertilizers with different NPK formulations enhance fresh aerial biomass, plant height and volume. Additionally, F. dolichophylla forms mycorrhizal associations, stores large amounts of fixed carbon in its stems, and bioaccumulates mercury, lead and arsenic. Despite its importance, Festuca dolichophylla remains poorly studied. Further research is needed to explore its ecology, breeding systems, diseases or ecotypes. Moreover, population and demographic studies are crucial to assess the impact of climate change on this species. Adaptive, strategic and organized management and conservation efforts are essential, particularly in Indigenous Andean settlements, where F. dolichophylla offers multiple applications and benefits. Furthermore, utilizing this species in grassland revegetation and restoration initiatives highlights the need for ongoing research and management endeavours to ensure its conservation and sustainable use.
