The high Andean wetlands of Peru provide not only the well-known ecosystem services such as water storage, flood mitigation, erosion control, and purification of water, but are also a source of income for local economies (as fodder), have medicinal properties, are a source of food, contribute to the development of ecotourism among many other uses. Economic and population growth have already damaged many parts of the high Andean wetlands including their rich flora. In order to promote the conservation of its diversity and unique flora, this study conducted extensive botanical explorations to identify and map the floristic composition of the high Andean wetlands of La Libertad, Peru, as well as their influence on local communities. The authors conducted explorations taking taxonomic, biogeographic and ethno biological data of the flora species as well as their therapeutic and economic botany. The study identified 64 species of flora distributed in 46 genera and 27 families including Asteraceae (with 8 species), Juncaceae (with 7 species), Poaceae (with 6 species), Cyperaceae (with 5 species), Licopodiaceae and Rosaceae (with 4 species each), Apiaceae, Gentianaceae, Orobanchaceae and Sphagnaceae (with 3 species each) and Poligonaceae (with 2 species). With reference to economic botany, it was found that 32.8% of species constitute resources with a very good economic benefit. The study concludes that it is imperative to take actions to protect the high Andean wetlands as they are ecosystems with great biodiversity. This study contribution expects to raise concerns regarding the increasing impact of economic and population growth on the loss of not only natural habitats but species as well. Conservation efforts will help protect the heritage of the Andes wetlands for future generations.

The Hill of Cerro Campana located in the north of the desert of the Pacific, is a unique ecosystem to host a high and specialbiological diversity, within which we find the "hummingbird ", very active and colorful bird species that feed on nectar and flower pollen. The objective of this work was to determine the number of interactions or visits of the hummingbirds to the species of flowering plants in the ACP Lomas del Cerro Campana, during 2021. For which were made 24 fixed points of counting, randomly distributed between the windward and leeward sides of this ridge and where interactions or visits to the flower of plants were recorded by the species of hummingbirds identified by direct and auditory observation. The presence of: Amazilia amazilia, Myrtis fanny, Myrmia micruraand Rhodopis vesper; birds that fed on the flowers of 20 plant species, belonging to 17 genera and 10 families; finding that Amazilia had preference for 16 plant species, Myrtis fannyby 06 species, Myrmia micruraby 08 species and Rhodopis vesperby 11 species of plants. These birds had a greater preference for interaction or visits by the flowers of species of the families Cactaceae, Bromeliaceae and Capparaceae. The plant species with which they had a greater number of interactions were: Puya ferruginea, with 12 interactions; Espostoa melanostele, Opuntia quitensiswith 9 each, Colicodendron scabridumwith 7; Tillandsia multiflora and Haageocereus decumbenswith 6 interactions each. These species, besides playing an important role in pollination, are an alternative to promote ecotourism in this ACP.
