Issued also in French under title: Évaluation et rapport de situation du COSEPAC sur le Bryum de Porsild, Haplodontium macrocarpum, au Canada. Includes bibliographic references: p. 51-57. "This rare moss is patchily distributed and occupies very little area across a large Canadian range. It relies on very specific, rare habitats on shaded calcareous substrates with continuous growing-season moisture. These habitats are threatened by drought, ice scour, storm events, and wildfire, all of which are expected to increase in severity with climate change. Some sites are also subject to threats from recreation and industrial development. Many habitat patches are smaller than would be required to support a viable population. With 19 known locations in eastern, western, and Arctic Canada, the distance between these patches exceeds the likely dispersal distance of the species. Although new colonies have been discovered in Alberta, the species is continuing to show declines and colony losses, especially in Newfoundland and Labrador, which will likely result in further declines"--Assessment Summary – November 2017, p. iii. gccst Endangered species gccst Wild plants gccst Assessment Committee on the Status of Endangered Wildlife in Canada.
