Abstract:

Digitization of a part of CIRAD's' xylotheque, one of the most important collections of tropical timber in the world, now allows researchers, experts in the field, trainers and archaeologists to have a new source of homogenized information. This corpus constitutes a unique database on the botanical characteristics of many species of Madagascar and could feed the research in both ecological and systematic fields by the possibility to define traits and criteria usable for example in phylogeny or functional ecology.

The island of Madagascar presents a remarkable floristic diversity, with a very high rate of endemism, making it a permanent laboratory for the study of the mechanisms governing evolution.

The digitization project was conducted in close coordination with other projects currently underway involving the same partners. 995 species are concerned by the ArchiWood project: 3 planes of anatomical sections for each species, associated with a total of 100 field notebooks (architectural sketches) and 20,000 slides.

Contents:

This dataset is composed of digitized legacy documents, all related to Madagascar biodiversity:

More than 2,300 illustrations and notes taken from field notebooks

More than 1,200 anatomical cuts

More than 70 photographs of plants and landscapes

Methods:

Digitization of anatomical cuts

For each species, there are 3 anatomical cuts associated with the 3 planes of symmetry of the material: radial, tangential and longitudinal. Each cut was scanned using an Olympus DP71 digital camera fitted on an Olympus BX60 microscope. The shooting software that drives the camera is Archimed from Microvision Instruments. The image format is 24 bits colored TIFF. Each image is 1600 x 1200 pixels for 3 different magnifications of the microscope: x40 (overview of the cut), x200 (main features anatomical from IAWA), x400 (highlighting fine lines such as punctuations).

Digitization of sketches (from field notebooks)

The digitized information in the field notebooks is made up of architectural sketches (with descriptive notes). The slides include additional remarkable visual information of field sketches (flowers, fruits, overview, geographical implantation conditions…). The sketches were scanned using a resolution of 300 dpi, 24 bits colors in JPEG format.

Digitization of photographs (24 x 36 mm)

The photographs were scanned at 600 dpi, 24 bits colors in JPEG format.

File management and data quality control

Controlling images and adding metadata operations were carried out by the researchers concerned in their field of activity (anatomy, botany, architecture). The homogenization and final harmonization of the metadata and data was carried out by the data manager.

State and local governments are increasingly interested in understanding the role forests and harvested wood products play in regional carbon sinks and storage, their potential contributions to state-level greenhouse gas (GHG) reductions, and the interactions between GHG reduction goals and potential economic opportunities. We used empirically driven process-based forest carbon dynamics and harvested wood product models in a systems-based approach to project the carbon impacts of various forest management and wood utilization activities in Maryland and Pennsylvania from 2007–2100. To quantify state-wide forest carbon dynamics, we integrated forest inventory data, harvest and management activity data, and remotely-sensed metrics of landuse change and natural forest disturbances within a participatory modeling approach. We accounted for net GHG emissions across (1) forest ecosystems (2) harvested wood products, (3) substitution benefits from wood product utilization, and (4) leakage assoc..., Primary data inputs to CBM-CFS3 included a detailed forest inventory, growth-yield relations to estimate forest productivity, and estimates of harvest yields and intensity, land-use change, and natural disturbances. Inventory data are categorized by a series of forest classifiers defining relevant characteristics such as spatially referenced boundaries, ownership, forest type, site productivity, or reserve status. Allometric equations are used to predict tree volume-to-biomass relationships (Boudewyn et al., 2007). For this study, forest inventory, growth-yield curves, and harvest data were estimated from the USDA Forest Service Forest Inventory and Analysis (FIA) program, which we accessed through the FIA DataMart (USDA Forest Service, 2019) using the rFIA package (Stanke et al., 2020) in the R programming environment (R Core Team, 2020), which enables data exploration and user-defined spatio-temporal queries and estimation of the FIA database (FIADB).

This dataset provides formatted input databases and post-processed results databases for the CBM-CFS3 ecosystem model portion of this analysis. Additionally, the post processed data from both the CBM-HWP-MD and CBM-HWP-PA harvest wood product models are provided. Please see the methods section and appendices for more detailed descriptions of data sources and data processing.

To be compatible with the CBM-CFS3 software, ecosystem model inputs were processed and reformatted into a MS access database format. The input databases are then run through the simulation software using a Python API where results are exported in CSV format. Ecosystem model results are post-processed to be inputted into the associated harvested wood product models which then provide additional CSV files.

Under Section 18 of the Clean Air Act 1993, many parts of Scotland are Smoke Control Areas. If you live in a smoke control area it is an offence to produce smoke from a chimney of a building, or a chimney of any fixed boiler or industrial plant, unless you're burning an authorised fuel or using exempt appliances (e.g. burners or stoves). In practice, this means that in a smoke control area it is illegal to burn house coal or wood in an open fire, although it is legal to burn these in a stove or other appliance that has been approved to burn that fuel. It is also illegal to deliver any unauthorised solid fuels, e.g. wood and normal house coal, to any premises in a smoke control area unless the seller can demonstrate that they were aware that the unauthorised solid fuel is to be burnt in an exempt appliance. Site name, designation date and website URL (for more information) are now mandatory attributes for this dataset.
