Butunjahon paleoklimatologiya ma'lumotlar xizmati daraxt halqasi ma'lumotlarining dunyodagi eng yirik jamoat arxivi bo'lgan Xalqaro Tree-Ring Ma'lumotlar Bankini (ITRDB) boshqaradi.  Nazorat ITRDB maslahat qo'mitasi tomonidan amalga oshiriladi. ITRDB xom halqa kengligi, yog'och zichligi, izotop o'lchovlari va oltita qit'adagi 5000 dan ortiq saytlardan sayt o'sishi indeksi xronologiyalarini o'z ichiga oladi. Qayta tiklangan iqlim parametrlari ham ayrim hududlar uchun mavjud.

Dendroxronologiya yog'ochda har yili o'zgarib turadigan halqa kengligini o'rganadi. Madaniy merosdan yog'ochdan yasalgan halqa naqshlari avvalgi xronologiya, ijtimoiy iqtisodiyot, tarixiy landshaft va undan foydalanish, iqlim va yog'och texnologiyasi haqida noyob ma'lumotlarni o'z ichiga oladi. DCCD - bu daraxt halqasi ma'lumotlarining raqamli ombori va interaktiv kutubxonasi. Uning mazmuni, jumladan, arxeologik yodgorliklar (shu jumladan eski landshaftlar), kema qoldiqlari, binolar, mebellar, rasmlar, haykaltaroshlik va musiqa asboblarini tadqiq qilish orqali ishlab chiqilgan. DCCD Tree-Ring Data Standard (TRiDaS) ga asoslanadi va boshqa keng qoʻllaniladigan maʼlumotlar formatlarini konvertatsiya qilishga imkon beradi. U raqamli daraxt halqasini o'lchash seriyalarini va o'rtacha xronologiyalarni, shuningdek ularning tavsiflovchi va izohlovchi metama'lumotlarini o'z ichiga oladi. Bu hissa qo'shuvchilarga o'z ma'lumotlariga kirishni nazorat qilish va boshqarish imkonini beradi.

​Xalqaro Multiproxy Paleofire ma'lumotlar bazasi (IMPD) - bu daraxt izlari, ko'mir va cho'kindi yozuvlari kabi tabiiy proksilardan olingan yong'in tarixi ma'lumotlari arxivi. IMPD butun dunyo bo'ylab yuqori sifatli paleofir yozuvlari uchun doimiy omborni ta'minlash uchun maslahat kengashining rahbarligi bilan tashkil etilgan.

The Tree Mortality Network is an initiative of the IUFRO task force on tree mortality. Our mission is to facilitate collaboration between scientists to combine expertise, knowledge and data, thereby allowing a global assessment of tree mortality and providing crucial information for forest managers and policymaking.

The European Atlas of Forest Tree Species is the first comprehensive publication of such a unique and essential environmental resource, that is, our trees. Leading scientists and forestry professionals have contributed in the many stages of the production of this atlas, through the collection of ground data on the location of tree species, elaboration of the distribution and suitability maps, production of the photographic material and compilation of the different chapters.

The main European added value of the ESBN has been the joint effort towards bringing together soil information collected in separate European countries, using very different methodologies, standards and scientific backgrounds, into one single geographic information system (GIS) while demonstrating that, at least for soil science, a “Europe without borders” is possible. Lengthy cross-border harmonisation sessions between bordering countries have resulted in a common fully harmonised soil geographical database of Europe at a nominal scale of 1:1,000,000. This database has allowed the production of the maps that are at the heart of the new “Soil Atlas of Europe".

The Wood Database contains around 600 species currently, which only represents about 1/4 of the database's creator's, Eric Meier, total collection! Eric's book, The Wood Dictionary: From Acacia to Ziricote, A Guide to the World's Wood is also available.

FloraVeg.EU is an online database of European flora and vegetation data prepared for various projects of the Vegetation Science Group, Department of Botany and Zoology, Faculty of Science, Masaryk University, Brno, Czech Republic. Most of the datasets were created in collaboration with partners from the European Vegetation Survey Working Group of the International Association for Vegetation Science. It uses the Pladias database platform developed in collaboration with the Institute of Botany of the Czech Academy of Sciences.
The Flora part of the database focuses on native and naturalized flora occurring in Europe. Cultivated plants are not within the scope of the database, although the most commonly cultivated crops and woody plants are included. Taxon concepts and nomenclature largely follow the Euro+Med PlantBase. Species are characterized by their biological traits, origin, ecological indicator values and their occurrence in habitat and vegetation types.
