The RENS Meetings have been held for more than 40 years: the first edition was celebrated from September 24th to 28th, 1973 in Santiago de Compostela. During the first two decades, the meetings were held annually with the exception of the years 1976, 1984 and 1988. In the nineties, the meetings were held more irregularly. Lastly, since 2001, meetings are held every two years until 2019. From next year, meetings will be celebrated every three years.
Given the large amount of information and in order to avoid its loss, the RENS Section of Land Use Change carried out the tedious but impressive task of digitizing the field guides correspondent to all the Meetings, as well as other complementary documents. Many researchers have devoted their time to this compilation, among them those responsible for the RENS Section, Armando Martínez Raya and Emilia Fernández Ondoño, and with special mention the Dr. Carlos Dorronsoro, José Aguilar and especially Roque Ortiz.
In the following table, you can find all the information up to the date of the previous RENS meetings celebrated.
