Data for: Loss of the world's smallest forests
Riva, Federico; Martin, Caroline; Millard, Koreen; Fahrig, Lenore — 2023-01-09 <p>A large number of small forests typically harbor higher biodiversity than a small number of large forests totaling the same area, suggesting that small patches are disproportionately valuable for biodiversity conservation. However, policies often favor protection of large forest patches. Here we demonstrate a global trend of higher deforestation in small than large forest patches: the likelihood that a randomly-selected forest plot disappeared between 1992 and 2020 increased with decreasing size of the forest patch containing that plot. Our results imply a disproportionate impact of forest loss on biodiversity relative to the total forest area removed. Achieving recent commitments of the post-2020 Global Biodiversity Framework will require revision of current policies and increased societal awareness of the importance of small habitat patches for biodiversity protection.</p> https://creativecommons.org/publicdomain/zero/1.0/

Pontone, Nicholas; Millard, Koreen; Thompson, Dan K.; Guindon, Luc; Beaudoin, André — 2024-02-07 Authors: Pontone, N., Millard, K., Thompson, D. K., Guindon, L., Beaudoin A. (2024) Contact:NicholasPontone@cmail.carleton.ca   Description:A map of peatland sub-classes (bog, poor fen, rich fen and permafrost peat complex) for the Canadian Boreal Forest circa 2020 created using a three-stage hierarchical classification framework. Training and validation data consisted of peatland locations derived from various sources (field data, aerial photo interpretation, measurements documented in literature). A combination of multispectral data, L-band SAR and C-Band interferometric SAR coherence, forest structure, and ancillary variables were used as model predictors. Ancillary data were used to mask agricultural areas and urban regions, and account for regions that may exhibit permafrost Pixel Values: 1: Bog2: Rich Fen3: Poor Fen4: Peatland Permafrost Complex5: Mineral Wetlands6: Water7: Upands8: Agriculture9: Urban Recommended Colours 1: 4C00732: FFFF003: E64C004: 7272725: F4C2C26: 0070FF7: 4C73008: 6231319: 000000   Please cite as: Pontone, N., Millard, K., Thompson, D.K., Guindon, L. and Beaudoin, A.

1.Turn on the map filter by clicking the “Limit by map area” toggle.
2.Move the map to display your area of interest. Holding the shift key and clicking to draw a box allows for zooming in on a specific area. Search results change as the map moves.
3.Access a record by clicking on an item in the search results or by clicking on a location pin and the linked record title.
Note: Clusters are intended to provide a visual preview of data location. Because there is a maximum of 50 records displayed on the map, they may not be a completely accurate reflection of the total number of search results.
