Bulkley Timber Supply Area - Forest Planning Data by Griess, Verena Christiane; Man, Cosmin; Spies, Jillian

This data package contains landscape level forest data, growth and yield data, metadata and models for modelling timber supply in the Bulkley Timber Supply Area, British Columbia, BC, Canada, using a spatially explicit forest management planning software, such as Forest Planning Studio Atlas (UBC), Patchworks (Spatial) or Woodstock (Remsoft).

Details can be found in the README file.

Multivariate maps of forest attributes for management units in Canada's boreal forestby Kyle Lochhead; Valerie LeMay; Gary Bull; Olaf Schwab; James Halperin

A spatially explicit “wall to wall” forest inventory of percent crown closure (CC), average height (Ht), average age (Age), and commercial species percentages derived using a multi-source inventory approach from Lochhead et al. (2017). This process involved compiling a suite of spatial layers including Landsat TM/ETM+ imagery, interpolated climate variables, topographic variables and other remote sensing products to be used as predictors and Canada’s National Forest Inventory photo plot information (1986-2010) as the source of dependant variables.Following Lochhead et al.(2017) the application used a method called kriging with external drift which relies on a system of non-linear models with spatially varying parameters to produce multivariate maps for the year 2010 at a 90m x 90m pixel resolution. The resulting maps are clipped to each forest management area (FMA) boundary which was sourced online ( For cases, where a 90 m x 90 m pixel window overlapped non-vegetated area (e.g., waterbodies) the forest attribute information was averaging using only the vegetated pixels (i.e., prorating). For more information on methods refer to the publication.

Great Bear Rainforest - landscape level planning databy Griess, Verena Christiane; Man, Cosmin; Leclerc, Marie-Eve

This dataset was developed to analyze various forest management alternatives for the area under the 2016 Great Bear Rainforest order (GBR order). It was developed for the use with common forest management planning software, such as WOODSTOCK (Remsoft) or Forest Planning Studio Atlas (FPS-Atlas). The area under the GBR order objectives includes 5 timber supply areas (TSA): Kingcome, Mid Coast, North Coast, Strathcona, and small sections of the Pacific. Geographical data were collected from the BC government's open data program in Canada (DataBC), and the BC government’s website on Strategic Land and Resource Planning for the GBR. The geographical databases accessed from public sources included: (1) administrative boundaries (e.g., GBR boundary, tree farm licenses, Indian reserves, etc.), (2) forest inventory (e.g., BC vegetation resource inventory, depletions to year 2015, environmentally sensitive areas, roads), and (3) management guidance (e.g., reserves, wildlife habitat areas, ungulate winter range, recreation inventory, sensitive watersheds, streams, rivers, lakes, wetlands). Some of the geographical datasets were not publicly available (e.g., logging operability) and are therefore not part of this dataset. The productive forest land base (PFLB) was established after excluding the Provincial and National Parks, reserves, various timber licences (tree farm licences, woodlots, other leases), and non-forested land. Coniferous tree-leading stands dominate the PFLB, with the most common species being western and mountain hemlock (Tsuga heterophylla and Tsuga mertensiana) (46.8%), western redcedar (Thuja plicata) (32.6%) and yellow cedar (Chamaecyparis nootkatensis) (8.9%). The yield curves associated with each stand type, and spatially with each polygon, were imported from the latest Timber Supply Review (TSR) documents for the Kingcome and Mid Coast TSAs. For the North Coast and Strathcona TSAs, the stand type information in the latest TSR documents was used to develop yield curves using the Variable Density Yield Projection (VDYP) (Forest Analysis and Inventory Branch, 2009) and Table Interpolation Program for Stand Yields (TIPSY) (BC MFLNRO, 2016d) software tools. The Pacific TSA does not have a published TSR document, yet the small sections of the Pacific TSA that fall under the GBR (0.7%) are spatially adjacent to the Kingcome TSA. It was assumed that Pacific TSA had similar yields and stand types to the Kingcome TSA The dataset represents the status quo at data preparation in the area.

This dataset provides fallow management, soil, and biodiversity metrics, and tree species community composition data for sampled fallows (n=47) and one primary forest stand in the community of San Jose [pseudonym] in the Peruvian Amazon from 2011. Management metrics were calculated from collected oral land use histories and air photo interpretation. Vegetation metrics were calculated from sampled vegetation plots in fallows 3-20 years of age and rarefied to common number of stems (n = 120). Fallow soils were collected and analyzed at La Molina University in Lima, Peru and adjusted for bulk density. Tree species data were collected for all stems > 2cm in sampled fallow vegetation plots. The dataset includes site level data on proportional break down of functional traits based on the relative proportion of stems per site; relative location of a site from Primary forest and village centre; time period since isolation; and measured soil properties adjusted for measured bulk density.
