Tallinna \u00dclikooli projektimeeskond l\u00f5petas taimestiku v\u00e4liuuringud oma suurel (\u00fcle 3000 ha) taastamisalal Suursoo \u2013 Leidissoo kuivendatud madalsookompleksis. Taimkatte anal\u00fc\u00fcse tehti neljateisk\u00fcmnel kraavide suhtes risti paigutatud transektil pikkusega 200 kuni 500 meetrit. Transektide pikkuse ja neil olevate uurimisruutude arvu m\u00e4\u00e4ras \u00e4ra taimkattemuster. \u00dchel transektil oli neli kuni kuus uurimisruutu suurusega 10 x 10 meetrit puu- ja p\u00f5\u00f5sarinde parameetrite (liik, t\u00fcve l\u00e4bim\u00f5\u00f5t, k\u00f5rgus, vanus, v\u00f5rade katvus) m\u00f5\u00f5tmiseks. Igas sellises ruudus oli rohu-puhmarinde uurimiseks kolm\u00a0 2 x 2 meetri suurust allruutu, mis omakorda jagati neljaks 1 x 1 meetriseks allruuduks. Samblarinde liikide ja katvuste hindamiseks oli igal ruutmeetrisel rohu-puhmarinde uurimisruudul kolm v\u00e4iksemat, 0.25 x 0.25 meetri suurust allruutu. Kokku on sisaldab saadud andmestik 69 puu- ja p\u00f5\u00f5sarinde anal\u00fc\u00fcsi, 207 rohurinde anal\u00fc\u00fcsi 2 x 2 meetristelt ja 828 1 x 1 meetristelt ruutudelt ning 2484 samblarinde anal\u00fc\u00fcsi. Need katavad alal levinud erinevaid taimkattet\u00fc\u00fcpe looduslikest ja kuivendusem\u00f5julistest madalsookooslustest kuni k\u00f5dusoometsadeni. Igalt 10 x 10 meetriselt anal\u00fc\u00fcsiruudult m\u00f5\u00f5deti ka soovee pH ja eri-elektrijuhtivus.<\/p>\n

V\u00e4liuuringuid j\u00e4tkatakse daiverite installeerimisega\u00a0veetaseme muutuste j\u00e4lgimiseks ja proovide kogumisega \u00fclemistest turbakihtidest (0-10 ja 10-20 cm), millest m\u00e4\u00e4ratakse laboratoorselt turba mahumass, tuhasus ning N, P, Ca, Mg, Fe sisaldus. Valitakse kohad kasvuhoonegaaside m\u00f5\u00f5tmiseks ja alustatakse m\u00f5\u00f5tmisi. See andmestik v\u00f5imaldab hinnata soo seisundit proovoaladel ning selle muutusi p\u00e4rast veetaseme t\u00f5stmist.<\/p>\n

Ala suuruse t\u00f5ttu ei ole v\u00f5imalik seda tiheda anal\u00fc\u00fcsiv\u00f5rguga katta, seet\u00f5ttu tehti detailsemaks kaardistamiseks droonifotod, mida kasutatakse koos taimkatte andmetega taimkattet\u00fc\u00fcpide kaardi koostamiseks. Multispektraalkaamera abil saadakse veel t\u00e4iendavat infot, n\u00e4iteks biomassi suuruse kohta, jm.<\/p>\n

Droonifotode p\u00f5hjal t\u00f6\u00f6deldud uurimistransekti (punane joon) ala kujutis projektiala NE osas Metsl\u00f5ugu oja \u00e4\u00e4res. Fotod on tehtud SenseFly eBee drooni multispektraalkaameraga Parrot Sequoia. Kaardistatud ala kohta arvutati normaliseeritud taimkatte erinevuste indeks (NDVI). Rohelised toonid n\u00e4itavad NDVI k\u00f5rgeid v\u00e4\u00e4rtusi (suur biomass) ja lillad toonid NDVI madalaid v\u00e4\u00e4rtusi (v\u00e4ike biomass).
