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".

An online flora of all known plants, supporting the Global Strategy for Plant Conservation. 1,325,388 names, 350,595 from accepted species, 56,408 images, 138,663 names with descriptions, 32,566 with distributions and 1,153,631 with references.

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.

InciWeb is an interagency all-risk incident information management system. The system was developed with two primary missions:

1. Provide the public a single source of incident related information

2. Provide a standardized reporting tool for the Public Affairs community

Learn how to use and navigate around InciWeb with this support guide.

A number of supporting systems automate the delivery of incident information to remote sources. This ensures that the information regarding active incidents is consistent, and the delivery is timely.

The Fire and Smoke Map displays information on ground level air quality monitors recording fine particulates (PM2.5) from smoke and other sources, as well as information on fires, smoke plume locations, and special statements about smoke issued by various sources.

​

This map is designed to:

• Allow the user to browse current conditions

• Show information relevant to the current location or another location of interest

This page provides links to the most recent versions of tools produced by the U.S. Forest Service PNW Research Station's Pacific Wildland Fire Sciences Laboratory in support of the Wildland Fire Air Quality Response Program and wildland fire operations.

The Interagency Wildland Fire Air Quality Response Program (IWFAQRP) was created to directly assess, communicate, and address risks posed by wildland fire smoke to the public as well as fire personnel. The program depends on four primary components: specially trained personnel called Air Resource Advisors, air quality monitoring, smoke concentration and dispersion modeling, and coordination and cooperation with agency partners.

The geospatial products described and distributed here depict the probability of high-severity fire, if a fire were to occur, for several ecoregions in the contiguous western US.

​

Users of these data should thoroughly read the README [pdf] file to better understand appropriate uses and interpretations of the data products distributed here.

Access wildfire data, live feeds, technology, and resources from esri. Use this collection of map layers, live data feeds, maps, organizations, blog posts, and how-to guides to help plan and manage your wildfire response.

We manage approximately 150,000 citations on all the topics related to wildland fire, including prescribed burning, smoke, climate change, paleofires, wildlife and invertebrates, and fire history, to name a few of the topics we cover. We have set up our site so that you can search and download documents without charge.

The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories.

The Global Historical Climatology Network daily (GHCNd) is an integrated database of daily climate summaries from land surface stations across the globe. GHCNd is made up of daily climate records from numerous sources that have been integrated and subjected to a common suite of quality assurance reviews.

​

GHCNd contains records from more than 100,000 stations in 180 countries and territories. NCEI provides numerous daily variables, including maximum and minimum temperature, total daily precipitation, snowfall, and snow depth. About half the stations only report precipitation. Both record length and period of record vary by station and cover intervals ranging from less than a year to more than 175 years.

DendroElevator is an open-source web platform for tree-ring image curation, visualization, and analysis. The system is optimized to maximize access to gigapixel images of tree rings and related paleoenvironmental proxy datatypes for remote research and distanced collaboration.

​

DendroElevator features a browser-based toolkit for tree-ring image visualization and time series measurement built for Elevator, a cloud-hosted digital asset management software with curation and robust streaming capabilities for file types of any size and common 2D and 3D formats, plus adaptability for various metadata and access permissions schemas.

​

DendroElevator constitutes an initial realization of our vision to create an open source, easily accessible online repository of high quality tree-ring imagery for entire collections of specimens. More information is here.

Welcome to the home of openDendro -- an open-source framework of the base analytic software tools used in dendrochronology in both the R and Python programming languages. Our goal is to create and curate a unified set of critical tools in open-source environments that will provide the necessary baseline for researchers using tree-ring data to adopt open-science practices and increase both rigor and transparency in dendrochronology.

N-TREND is a mainly tree-ring community driven initiative to bring together dendroclimatologists to identify a collective strategy to improve large-scale reconstructions of summer temperatures from new and existing tree-ring archives.

The Building Archaeology Research Database (BARD) has been designed as an easy to use and accessible summary index for both published and unpublished building records. It’s main aim is to encourage involvement in building archaeology and its current 23,000+ records (including many tree-ring dated buildings) can be freely searched on-line. 

1. BARD is a primarily an on-line scientific research tool showing how building styles developed through time and across regions.

2. BARD currently contains over 2500 tree-ring dated buildings and key features of timber-framing such as crucks, crown posts, wealdens, queen posts, etc can be selected and plotted.

3. BARD provides systematic recording system for buildings that also helps to narrow down the likely date of construction.
