In this study, the main hypothesis to be tested is whether the population of L. kunkelii is stable or not. The study site is located in Gran Canaria. Monthly censuses of the population recording size (height and diameter), mortality, regeneration, and presence of reproductive structures in each individual were carried out, and this monthly information of variables was correlated with climatic variables. | Turkish Journal of Botany http://journals.tubitak.gov.tr/botany/ Research Note Turk J Bot (2018) 42: 362-369 © TÜBİTAK doi:10.3906/bot-1707-63 Monitoring an endangered and rare plant: population growth and viability of Lotus kunkelii (Esteve) Bramwell and Davis (Gran Canaria – Canary Islands) 1 2 3 Agustín NARANJO-CIGALA , Marcos SALAS , Francisco Javier DÍAZ , 2 4 5, Aday Miguel GONZÁLEZ-GARCÍA , Ana RAMOS , José Ramón ARÉVALO * 1 Department of Geography, University of Las Palmas de Gran Canaria, Las Palmas de Gran Canaria, Canary Islands, Spain 2 IUNAT Instituto de Estudios Ambientales y Recursos Naturales, University of Las Palmas de Gran Canaria, Canary Islands, Spain 3 Department of Animal Biology, Soil Science and Geology, University of La Laguna, La Laguna, Canary Islands, Spain 4 Environmental Service, Cabildo de Gran Canaria Las Palmas de Gran Canaria, Canary Islands, Spain 5 Department of Botany, Ecology and Plant Physiology, University of La Laguna, La Laguna, Canary Islands, Spain Received: 27.07.2017 Accepted/Published Online: 03.04.2018 Final Version: 03.05.2018 Abstract: Species monitoring is a valuable tool that can be used to answer a wide range of questions directly related to species conservation, management, and population improvement. We monitored the only remaining population of Lotus kunkelii on a monthly basis over 3 years to reveal important characteristics of the population that could help protect it. In this study, the main hypothesis to be tested is whether the population of L. kunkelii is stable or not. The study site is located in Gran Canaria. Monthly censuses of the population recording size (height and diameter), mortality, regeneration, and presence of reproductive structures in each individual were carried out, and this monthly information of variables was correlated with climatic variables. The population is growing (from 105 to more than 200 individuals during the studied time) at a slow pace and is restricted by the .
