In addition to them, the following persons helped to carry out field work: Aira Alasi, Allar Annusver, Alina Gorecky, Elo Hermann, Dagmar Hoder, Epp Hunt, Katrin Jürgens, Alo Kaasik, Laila Kaasik, Inga Kangur, Julia Koblitzek, Marten Kose, Tõnis Peeter Kull, Siim Kuresoo, Säde Lahtmets, Vilge Lahtmets, Aleksei Lotman, Martti Maasik, Eha Metsallik, Rita Miller, Laine Opp, Tiina Orason, Anneli Palo, Kristi Parro, Raul Pihu, Tiit Randla, Martti Rohusaar, Urmo Saar, Jüri-Ott Salm, Eke Jaan Sarv, Erlend Sarv, Aleksander Sprogis, Monika Suškevi s, Jaak Tamboom, Üllar Tammekänd, Ants Tekko, Sirje Tekko, Ülle Valgi, Enn Vilbaste, Mariliis Võsu, Sirje Zahkna and Mark Zirk. In most cases, both sides of the worksheet were filled out for each mire site. In cases where the site turned out to be strongly influenced by human impact or was very similar to the neighbouring one, only the evaluation form was filled out.
7.7 Development of geographical information system 7.7.1 Database In the course of database management some of the original 13,901 data sheets were united into one, some divided into two or three, some united with data sheets from the older period, and a few were left out of the database (those erroneously filled out not for the habitats marked on the map, but somewhere in the neighbourhood). All in all, 13,850 data sheets from 2009–2010 were added into the database. All textual data were computerized using the special Visual FoxPro 9.0 application designed and programmed by Lauri Lutsar. Data input was carried out by Berit Hänilane, Eerik Leibak, Talis Lepik, Taime Puura and Gerda Spuul. All data sheets were checked, missing data (e.g. the Natura 2000 habitat type) interpreted and added, and individual differences of different experts unified by Eerik Leibak. Though only mires were intended to be checked in the field, the selected areas actually contained a large variety of different habitats. This was caused by the errata on the basic map, use of the same map symbols for different site types (e.g. for fens and paludifying grasslands), fulfilment of data sheets per neighbouring habitats if field experts were strayed from the proper area, etc. In the result, the mentioned 13,850 data sheets represented the following site type groups: mires – 8,676 sheets, paludifying grasslands – 2,049 sheets, peatland forests – 1,587 sheets, paludifying forests – 409 sheets, ESTONIAN MIRES: INVENTORY OF HABITATS
