Ekområden och punktskiktet ekar från 2006, uppdaterat 2017 med hjälp av nya fältinventeringar och flygbildstolkning utifrån skötselaspekter, samt komplettering med nyfunna jätteekar. Shp-filen Kärnområden är dock densamma som skapades 2007 utifrån inventeringen 2006, eftersom inga nya värdeklassningar har gjorts inom projektet. <\/SPAN><\/P>

Polygonerna visar områden med kluster av ekområden och karterade ekar som bedömts som kärnområden för Stockholm stads Ekmiljöer. Buffertzoner på 250 m gjorda runt alla klass- 1 och 2-ekar från punktskiktet \u201dEkar\u201d har legat till grund för den geografiska avgränsningen. Övriga kriterier har varit förekomst minst en klass 1- ekområde i ett kärnområde samt totalt minst 30 grova ekar av klass 1-3, varav minst 10 värdefulla ekar av klass 1-2.<\/SPAN><\/P>

Mer information; Data har framställts för projektet \u201dStockholms Unika Ekmiljöer\u201d på uppdrag av markkontoret, Stockholms Stad. Beskrivning av metoden finns i Rapporten \u201dStockholms unika ekmiljöer \u2013 Metodutveckling och litteraturstudie 2006-10-01\u201d. Analysresultat samt mer information finns i slutrapport \u201dStockholms unika ekmiljöer \u2013 Förekomst, bevarande och utveckling\u201d skriven av Ekologigruppen AB, maj 2007.
