Plants used for hedging in Patagonian cities: an ethnobotanical contribution to conservation
Hedges constitute a significant part of Patagonian city landscapes, and can be very important not only as reservoirs of biodiversity, but also as possible sources of invasion. In this work, carried out in eight Patagonian tourist cities, species richness was estimated and the botanical families and biogeographical origin of the plants chosen for hedges were recorded. Considering the influence of European colonists on cultural and landscaping development in the region, one would expect a high proportion of resources to be of Holarctic origin. Species were identified in 100 homes chosen at random in each locality (San Martín de los Andes, Villa la Angostura, Dina Huapi, El Bolsón, Lago Puelo, Esquel and Trevelin) and in 300 homes in Bariloche, due to its greater size. Total plant richness was 137 species, the most common being Cytisus scoparius (L.) Link (9%), Rosa sp. (8%), Pseudotsuga menziesii (Mirb.) Franco (7%), Cupressus macrocarpa Hartw. ex Gordon (5%) and Ligustrum sinense Lour. (3%). Of the 48 botanical families represented, the most frequent were Rosaceae, Fabaceae, Cupressaceae and Pinaceae (67% of the total registered). Species come from the following regions: Holarctic (72%), Antarctic (23%), Paleotropical (19%), Neotropical (5%) and Australian (2%). We conclude that the hedges studied, in terms of species richness, display similarities with the main ornamental species at a global level. However, the presence of Antarctic elements (32 species) indicates the incorporation of species native to Andean-Patagonian forests, and therefore an important role is being played here in terms of conservation. In addition, our survey shows that certain species may present a risk of biological invasion (e.g., Sorbus aucuparia L., Crataegus monogyna Jacq., Ulex europaeus L.) and we therefore propose that the population should be warned about the negative effects of these species.

Los cercos vivos son parte significativa del paisaje de las ciudades de la Patagonia y pueden ser muy- importantes no sólo como reservorios de biodiversidad sino también como posibles fuentes de invasiones. En este trabajo se estimó la riqueza de especies, sus familias botánicas y el origen biogeográfico de las plantas seleccionadas como cercos vivos en ocho ciudades turísticas de la Patagonia. Si se considera la influencia que los colonos europeos han tenido sobre el desarrollo cultural y paisajístico de la región, es esperable una proporción elevada de recursos de origen Holártico. Se identificaron las especies en 100 casas elegidas al azar por localidad (San Martín de los Andes, Villa la Angostura, Dina Huapi, El Bolsón, Lago Puelo, Esquel y Trevelin) y 300 para Bariloche dado el mayor tamaño de la ciudad. La riqueza total correspondió a 137 especies, y las más comunes fueron: Cytisus scoparius (L.) Link (9%), Rosa sp. (8%), Pseudotsuga menziesii (Mirb.) Franco (7%), Cupressus macrocarpa Hartw. ex Gordon (5%) y Ligustrum sinense Lour. (3%). De las 48 familias botánicas representadas, las más frecuentes fueron: Rosaceae, Fabaceae, Cupressaceae y Pinaceae (67% del total del registro). Las especies provienen de la región Holártica (72%), de la Antártica (23%), Paleotropical (19%), Neotropical (5%) y Australiana (2%). Se concluye que los cercos estudiados muestran en términos de riqueza de especies, similitudes con las principales especies ornamentales a nivel global. Sin embargo, la presencia de elementos antárticos (32 especies) indicaría la incorporación de especies nativas de los bosques andino-patagónicos en los criterios locales, por ende, con un valioso papel a nivel de la conservación. Por otra parte, el relevamiento muestra que ciertas especies pueden representar riesgos de invasiones biológicas (e.g., Sorbus aucuparia L., Crataegus monogyna Jacq., Ulex europaeus L.), por lo que se propone la difusión de sus efectos negativos en la población.
